PVD technology appeared in the late 1970s. The films prepared have the advantages of high hardness, low friction coefficient, good wear resistance and chemical stability. The initial successful application in the field of high-speed steel cutting tools attracted great attention from manufacturing industries around the world. While developing high-performance and high-reliability coating equipment, people also conducted more in-depth coatings on cemented carbide and ceramic cutting tools. layer application research. Compared with the CVD process, the PVD process has a low processing temperature and has no effect on the bending strength of the tool material below 600°C; the internal stress state of the film is compressive stress, which is more suitable for coating precision and complex carbide tools; PVD The process has no adverse impact on the environment and is in line with the development direction of modern green manufacturing. At present, PVD coating technology has been widely used in the coating treatment of carbide end mills, drill bits, step drills, oil hole drills, reamers, taps, indexable milling inserts, special-shaped tools, welding tools, etc.What does PVD coating mean?Meaning: PVD (Physical Vapor Deposition) physical vapor deposition technology: means that under vacuum conditions, physical methods are used to vaporize the material source - solid or liquid surface into gas atoms, molecules or partially ionized into ions, and pass through low-pressure gas (or plasma body) process, a technology that deposits thin films with special functions on the surface of a substrate.The PVD coating we usually know is the so-called vacuum coating technology. Vacuum coating technology and processes have been widely used in vacuum coating processing companies. PVD coating is mainly coated under vacuum conditions. Its usage industries and market prospects are also It is very broad, and the process flow and construction conditions of PVD co

Which electroplating color is easiest to change color? 1. White steel: electroplated stainless steel, which is the most common white electroplating material; 2. Light gold, frosted gold: gold, mostly using 14K gold plating; 3. Rose gold: Rose K gold electroplating, suitable for young and fashionable consumers; 4. Light silver: Electroplated silver, the purest of all whites, is more common in earrings and brooches. It is hypoallergenic and unlike sterling silver which easily oxidizes and turns black, it ensures a pure and durable color; 5. Gun color: similar to the color of the surface of a gun barrel, black and shiny, stable in nature, and least likely to change color; 6. Oxidized silver: Pure silver easily turns black in the air. After oxidation treatment, its properties become more stable, and its color is more ancient and soft, giving it a retro look and feel; 7. Bronze oxidation: red, ancient color; 9. Platinum: electroplated platinum. It is the electroplating with the best color and quality inside white, and is usually electroplated on the surface of copper materials. Causes and solutions of graying White fog after nickel plating usually occurs together with blackening of deep holes and other places. It is because the nickel plating solution is contaminated by metal impurities and organic impurities. Metal impurities such as zinc and copper will cause the coating in the low current area to become dark and black; too many organic impurities, improper use of additives or imbalance (see note below) will cause the nickel plating layer to become foggy and white. The solution is to clean the plating solution. deal with. The treatment process is as follows; (1) Take out the anode, add 5ml/l of impurity removal water,

If you're already clear on what a mechanical keyboard is, and you've read the article What Brand of Mechanical Keyboard is Good, what you might want to pick, is the shaft of the mechanical keyboard. Mechanical keyboard what axis is good it, we first look at the mechanical keyboard white axis, black axis, green axis, tea axis, red axis difference. (In most cases, the term "mechanical keyboard axis" refers to the Cherry MX axis.) Differences between mechanical keyboard axes (overview) White shaft Higher operating pressure grams than the Black Shaft Stronger segmentation than the Tea Shaft Discontinued Black shaft Operating pressure: 58.9g±14.7g No segmentation sensation Green Shaft Operating Pressure: 58.9g±14.7g Tactile Pressure: 58.9g±19.6g Segmented feeling is very good Tea Shaft Operating pressure: 44.1g±14.7g Tactile pressure: 54.0g±14.7g Slight Segmentation Red Shaft Operating Pressure: 44.1g±14.7g No Segmentation *Yellow shaft--Ryber's own developed shaft, pressure 50g PS: What is a mechanical keyboard's "feel"? It's hard to describe in words. If you slowly scroll the mouse wheel, you will feel a scale is slightly stuck, but if you slightly push, it will scroll over quickly. Keyboards have a similar feel to this. It's easy to understand after using a mechanical keyboard that has a sense of paragraphing. What is the best axis for mechanical keyboards The reason why there are various mechanical keyboard axes is so that users can find the right one for them. The various gaming axes are applicable: Black axis: suitable for playing games, typing (not recommended if finger po

Mechanical keyboard with a long life and extraordinary feel, "reclaimed" the position once replaced by the membrane keyboard, became the peripheral players and enthusiasts of the heart. In addition to the feel and life, the mechanical keyboard attraction lies in the freedom to replace the keycaps, change a set of their favorite keycaps is like changing a keyboard, the player can according to their own preferences or needs, so that their keyboard has a unique appearance, and the feel of the keyboard will also change. If the shaft determines the basic feel of the mechanical keyboard, then the keycaps are the icing on the cake for the user's feel in use. Different colors, different processes, different materials of the keycaps will not only affect the face value of the keyboard, but also affect the feel of the keyboard, thus affecting the use of the keyboard experience. Mechanical keyboard keycaps can be freely replaced, but the price is high, part of the limited edition keycap price can even be compared with the high-end keyboard shoulder, and mechanical keyboard keycap material, although common are plastic, but the different materials do not have the characteristics of the different materials, and there are many other special materials of the keycap, favored by the enthusiasts, just a keycap price can reach thousands of dollars. Common mechanical keyboard keycaps can be divided into ABS, PBT, POM three materials, of which ABS in the mechanical keyboard in the highest usage rate, whether it is a few hundred dollars of the popular type of products or thousands of dollars of the flagship keyboard, you can see the figure of the ABS ABS plastic is acrylonitrile (A) - butadiene (B) - styrene (S) of the copolymer, a synthesis of the performance of the three components,

1. Pin buckle This kind of watch buckle is the most common now, usually used in the leather strap watch. This kind of above will have more than one hole, convenient for different people to adjust the length of the strap. Because there is a certain distance between each hole, so the adjustment time may not be so in line with the length of the wrist, but this kind of buckle is more solid, leather strap is basically the use of this kind of buckle. 2.Butterfly buckle Butterfly buckle is two sides of the double dark buckle, generally are metal bracelet with this kind of buckle, and more appear in the ladies watch, this kind of buckle is more beautiful, and there is basically no trace after the buckle. Bidirectional clasp is also more solid and fixed. If the length of the bracelet is not suitable, you can only cut off the bracelet. 3. hook buckle Hook buckle in my opinion is the most convenient kind of clasp, generally there will be a hook shape first hang the other side, and then buckle, this kind of clasp is not only firm, but also can be adjusted at will the length of the bracelet, because it is the other side is stuck in the bracelet, after opening the bracelet can be adjusted on the bracelet. 4. folding insurance buckle This is a common type of buckle on the stainless steel bracelet, the two pieces of the same length of the bracelet will be folded, the other side will also be buckled, so that the two-way insurance, more solid, and can not see any traces. 5. bracelet buckle This kind of clasp will generally appear in the ladies watch, is at the end of the two sides of the watch chain, the shape of the clasp and the watch chain is the same, equivalent to the removal of a ring in the watch chain, a very small folding clasp, after the clasp on the square which

Tea axis is called the most luxurious axis, mainly because it is the mechanical keyboard in the "oil", "all-purpose axis"! If you are an Internet practitioner, or often deal with the computer partners, not limited to work, games, then you for a variety of keyboards are not so strange. You will find more and more people around you, the use of the keyboard are from the ordinary membrane keyboard slowly transitioned to the mechanical keyboard. Mechanical keyboards and ordinary membrane keyboards from the structure, there is a very obvious difference, that is, the mechanical axis, that is, each key of the mechanical keyboard has a separate axis, this mechanical axis is actually a switch used to control the closure. The various axes in the current market can be broadly categorized into: black axis, green axis, red axis, tea axis, and Romer-G and optical axis, electrostatic capacitance axes of these categories. So, what is the role of these mechanical shafts? Because of the existence of mechanical shafts, so in the keystrokes will feel a stronger sense of paragraph, and because of the mechanical keyboard some axis design makes the mechanical keyboard response more sensitive, but become more suitable for games and entertainment. For example, the black axis is generally more suitable for games and entertainment, the green axis is suitable for typing, but there is a drawback is that the sound of the keys is relatively large, etc., it can be said that different axes for different people, the use of different scenarios, the feeling that the fish and the bear's paw can't have it both ways! So, is there a mechanical axis body is more omnipotent, let us fish and bear the bear's paw can be both? As the saying goes: there is a demand there is a market, in the mechan

Let's talk about metal straps first. Metal straps are divided into precious metal materials and other metal materials, and the common precious metal materials used as watch straps are platinum and k-gold. The precious metals commonly used as watchbands are platinum and k-gold, while other metal watchbands are mostly made of steel and titanium. One of the biggest advantages of metal watch bands is that they are durable and have a long service life, and if there are scratches, they can be treated and restored to as good as new after treatment. This is why most people are willing to wear watches with metal straps. The disadvantages are: one is afraid of sweat, two is afraid of collision, three is afraid of discoloration. The watch band as a direct contact with the skin part, due to the length of use, use habits and environment, more or less will produce dirt, metal watch band in contact with sweat without timely treatment, easy to accumulate dirt and thus lead to wear and corrosion of the situation, this situation is easy to dirty clothing or even make the wearer's skin allergies. In addition to the need to clean up sweat in time, precious metals such as k gold material, due to the material itself is softer, for the impact and other accidental touch bearing capacity is weak, easy to scratch the surface of the strap in daily life. Then, with the growth of wearing time, as well as wearing with the human body sweat contact, easy to make the metal discoloration. Below is a picture of a metal watch band. The biggest advantage of the leather strap is that it is skin-friendly. That is, in terms of wearing comfort, leather strap is more comfortable, especially in the cold fall and winter seasons to wear more warm and comfortable. Compared with other materials, leather straps are less likely to harm skin and clothing. In addition to the material itself, the

The Milanese steel band, a combination of fashion and classic, uses a smooth surface with polished treatment, which is soft and comfortable to wear on the wrist, with a unique flavor. Because the outer layer of the strap uses magnetic treatment, the length of the strap can be adjusted arbitrarily by using the magnetic head at the end, and the most comfortable length can be selected to fit the wrist perfectly. Among the series of Feike watches, the Milanese strap is one of the rare straps that can perfectly embody literature and elegance, business and leisure at the same time. 1. What is "Milanese"? Milanese is the phonetic translation of the original name "Milanese", a warp knitting technique originally invented around 1960. Warp-knitting technology was transformed from the warp-knitting process of the weaving industry, like weaving a group or groups of warp yarns arranged in parallel, compiled along the longitudinal direction, using two groups of reverse characteristics of the weaving of diamond-shaped pattern. Due to the difficulty of operation and high technical requirements, the tiny parts between the bands bring flexibility while making the cost soar. Traditional webbing, there will be visible threads on both sides of the edge, while Milanese is not, Feike's method is to use laser welding technology to weld all the threads on both sides of the edge, and then flat grinding, so that the whole strap threads are completely closed, and it looks smooth and flat. 2.How the magnetism of the steel band is formed Why the steel band will be magnetic, is due to the stainless steel melting cold drawing before, Feike in the manufacture of materials added to the magnetic powder, and then pull the mo

What is a watch movement? A watch movement is the device housed in the case that powers the watch. The term originated in early clocks and watches that consisted of many functioning parts. Movement types vary from watch to watch and include mechanical, automatic and quartz movements. Remember, regardless of the type of movement in a watch, its core purpose is to tell accurate time. Ready to learn what a mechanical movement is? This watch basics guide will explain mechanical movements and much more. What are the types of watch movements? Watch movements can be divided into two categories: mechanical movements and quartz movements. As the name suggests, a mechanical movement consists of a series of interconnected parts that operate "mechanically" without the use of electricity or batteries. Quartz movements, on the other hand, are battery-operated watch movements. How does a mechanical watch work? There are two types of mechanical watches: manual and automatic. The former requires the watch to be wound manually by turning the crown every few days. The latter, invented at the end of the 18th century, has an automatic winding mechanism, meaning that it does not need to be wound manually if the watch is worn continuously. The movements of both types of mechanical watches consist of a crown, a mainspring, a gear train, an escapement and a balance wheel. The principle is not complicated. The mainspring is the power reserve, which stores energy and transfers it through the gears and hairspring, regulating the release of energy and ultimately powering the watch.

Recently, as e-sports games continue to break through the circle, higher performance mechanical keyboards have become a "must enter the pit" for many novice players. But choose mass production mechanical keyboard or custom? Which brand and which accessories to choose? What is the right price? A variety of choices in front of consumers have become a mechanical keyboard problem, relying on various keyboard rankings is the norm, but the final experience may not meet expectations. May wish to understand the keyboard structure, familiar with the keyboard selection to start, even entry-level players can choose to suit their own heart water keyboard. The mechanical keyboard mainly includes five structures: shell, PCB, positioning board, shaft body and key cap. At present, in order to match different needs, many mechanical keyboards have focused on the transformation of part of the structure. Keyboard white can first understand the structure and components of the mechanical keyboard, familiar with the layout (keyboard layout), keyboard height and even customized keyboard fixed scheme options, according to their own more attention to the effect, to make a reasonable choice. With a basic understanding of the mechanical keyboard, you can begin to familiarize yourself with the corresponding product choices in the major price ranges currently on the market. In the low price range of 100 yuan to 400 yuan, the appearance design of mechanical keyboard products is relatively simple, generally only in the mechanical shaft, key cap and collocation to meet the basic game and office needs of consum

Keyboard (1) Material: plastic, metal, wood. Plastic, needless to say, the cheapest shell, and the color is also very rich, and milk shell and transparent shell is very suitable for PCB with bottom light, the effect is obvious. Of course, the disadvantages are also common to plastic, the shell is not strong and easy to deform. Metal, generally CNC cutting, is strong and more tough, and the color after the anode is even richer than plastic, and because of the strong plasticity of the material, many high-end custom kits are metal shells. The disadvantage is fear of falling, fear of touching, once the metal bump is generally irreparable scars, and the price is also higher. Wood, wood shell because of the universality of the problem, generally used in 60% of the keyboard, the color of the material is of course related to what wood, like a little dark walnut, like a clear texture of the yellow pear, like a little bright pine, it can be said that the choice of wood types is still very much. As for the disadvantage is that the wood will have a certain change in shell size due to the climate, and even crack.

The so-called customized mechanical keyboard is, of course, a customized mechanical keyboard. Customization is the meaning of customization, the word customization comes from Hong Kong and Taiwan, the mainland is not common. The mechanical keyboard refers to a keyboard that uses a mechanical switch (also known as a mechanical shaft) to trigger key technology. Other trigger methods are common thin film, electrostatic capacitance, etc., so there are also customized electrostatic capacitance keyboards. The mechanical oem parts keyboard can be customized, the necessary conditions for the existence of: the overall cost of design, manufacturing and sales, to reach the range of consumers. To be specific: High standard of core accessories and low cost (based on Cherry MX switch, patent expired) The keyboard structure is relatively simple, there is no complex mechanical structure The electronic hardware demand of the keyboard is not high, and the component cost and PCB design cost are low Open source firmware supports software capabilities with less development effort Affordable processing costs Social/e-commerce platform sales Why choose customization? minority individuation Rich gameplay Customized gameplay Customized gameplay

Positioning Plate Positioning plate: PC, PC semi-steel, FR4 glass fiber, aluminum alloy, brass, cardboard, beech laminate. PC positioning board: with 4f linear axis feel more comfortable, the material is soft, the rebound is very comfortable, with a strong paragraph axis will slightly absorb to ease the feeling of the bottom paragraph, it should be noted that the installation needs to be slightly careful, otherwise it is easy to scratch the surface, personal favorite collocation. PC semi-steel positioning plate: The letter area because there is no steel, psychologically some feel unstable, but in fact, there is no impact, compared with the PC feel softer, the installation is slightly more troublesome than the PC, and I don't like it. Carbon fiber positioning plate: the overall feel is still soft, but it is harder than the PC feel, and the rebound is strong but not shocking, the customized price is cheaper, and the personal second choice.

Linear axis: linear axis press no feeling of stuttering, press all the way smoothly, smooth trigger -> Smooth bottom of this experience, recommended shaft body are: TTC fast silver shaft, TTC gold powder shaft, Jiadalon G yellow shaft, Tiffany shaft and so on. Paragraph axis: The paragraph axis is the button midway to have a feeling of stutness, smooth - Caton Smooth this press experience, recommended shaft body are: TTC Moon white, cherry tea shaft, HP Holy Panda shaft. Click axis: The sound axis of Click is that there will be a crisp sound in the middle of the key along with the feeling of the paragraph axis, smooth -> Caton + Sound -> Smooth this press experience, recommended shaft body are: cherry green shaft, Kaihua BOX white and so on. (2) Brand: Cherry Cherry shaft, Jiadalon shaft, Kaihua shaft, Tiffany shaft, Saint Panda shaft,Cherry Cherry shaft Cherry Black axis: The pressure gram of the black axis is 80g, the trigger key path is 1.5mm, and the click life is about 60 million times. The black axis has no sense of paragraph, high pressure grams, sensitive trigger, completely silent, giving people a straight up and down feel, due to the short key path, fast trigger, more suitable for competitive games. Although the black axis can also be used for typing, due to the high pressure required, the fingers may be tired after a long time. Due to the "hard feel" of the black Axis, it is not the most popular choice in the game industry. For professional players, in some games that require a large number of repetit

Keycaps Types: ABS, PBT, POM, metal, resin, among which ABS and PBT are the most common Mechanical keyboard keycaps ABS: Material: ABS plastic is A terpolymer of acrylonitrile (A), butadiene (B), styrene (S) three monomers, the relative content of the three monomers can be arbitrarily changed to make a variety of resins. Features: ABS plastic has the common properties of three components, A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, S makes it have the processing and forming characteristics of thermoplastics and improve electrical properties. Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easy access to raw materials, good comprehensive performance, cheap price and wide use. Disadvantages: easy to grease, depending on whether the coating, the surface of the key looks shiny and shiny, sensory and physical feeling will be greatly reduced. PBT: Material: Polybutylene terephthalate (PBT), is a polyester made of terephthalic acid and 1, 4-butanediol condensation, is an important thermoplastic polyester, one of the five major engineering pla

As a product for a specific market, children's watches don't need excessive performance and complicated functions, they only need to do the most basic positioning and tracking and guarantee communication, basically even if it is a qualified product. For parents, the child's location data is one of the most concerned information. In the industry's view, children's products are more difficult to build compared to adult products, one of the main reasons is that manufacturers need to balance the needs of children and parents: on the one hand, parents need to keep track of the child's dynamics to ensure that the child can grow up safely and healthily; on the other hand, today's teenagers are more autonomous, and need to own a certain amount of their own privacy and space for activities. In this regard, relevant experts said that children's smartphone manufacturers should dig deep into the industry moat through in-depth insight into the needs of users, and constantly carry out technological research and development and product innovation. Taking children's smartwatch brand Little Genius as an example, the recently launched new product Z9 is equipped with an independent positioning GPS chip, an exclusive barometer, a five-fold sensor, and 3DSYS upgraded algorithms and low-power WIFI. for example, parents can learn where the child has stayed based on the trajectory heatmap; when the child is near the water, the watch can also be given a reminder. In terms of health monitoring, Little Genius combines the dynamic monitoring of the temperature curve in hospitals, and improves the accuracy of temperature measurement after combining a large number of users' fever data model information through physiological medical research + biological modeling

With the arrival of the original Apple Apple Watch, there are many domestic brands are online smart watches and sports bracelets and other products, then for watches and bracelets, the user's use of different environments, and ultimately different choices, so what is the difference between the two? The difference between a smart watch and a bracelet - watch As the name suggests, its most basic function is the function of a watch, with the appearance of an ordinary watch, a relatively large dial, appearance, the weight is greater than the bracelet, and waterproof is slightly inferior to the bracelet, but the general movement of sweat stains, splashes of water and so on are able to cope with. Smartwatches use an internal smart system to transfer phone calls, messages, photos, music, etc. from your phone to your watch via Bluetooth synchronization. Most smartwatches also need to be connected to a cell phone, and there are some that can be plugged into a cell phone card, which is equivalent to a watch-type cell phone. That is to say, there are two ways for smartwatches to work, depending on the cell phone and not depending on the cell phone as a terminal, and the one that does not depend on the cell phone is an independent terminal. The difference between a smart watch and a bracelet - bracelet In fact, a bracelet, just like the most primitive jewelry, must be lightweight and compact from the shape, it is the use of the sensor chip inside the bracelet, through the collection of information on the human body, health monitoring, sports pedometer, sleep monitoring, heart rate monitoring, fall determination, sedentary reminder, etc., but it can't be an

This question can be answered according to the Zhihu tradition, first ask if, then ask why. Judging from the people around me, probably more young people are not wearing anything, but the watch-wearing crowd does have a majority of young people wearing smartwatches. Smartwatches, and I have a few of them, I like them as a direct result of being able to pull out my phone less often. In recent years, the watch is no longer as a single function of the decorative objects, the development of a more practical smart wearable devices, to make up for the lack of cell phones or replace some of the functions of the phone, so that the travel is more simplified. However, with the development of the market, there are now a wide variety of smart wearable devices, and some questions arise when shopping, most people are at a loss when shopping, especially those who have not been exposed to smart watches. I have purchased some smartwatches, and the following describes how my shopping process was. The difference between smartwatches and smart bracelets Smart watches tend to be much more expensive than smart bracelets, and many people say that smart watches are large smart bracelets, which is not wrong to describe a certain point of view, smart watches have a larger display area, more functions, and more professional data monitoring than smart bracelets. Some good smart bracelets can receive phone calls, can have independent applications, similar to a small cell phone, while the bracelet is based on watching the

Generally speaking, there are two parts of a smartwatch that demonstrate CMF design capability: the watch body itself and the watch band. Compared to the current structure of the watch body (case, bezel, bezel, crown, etc.), no matter the type of material, shape, texture, structure and color styles, the future of the watch band will have a higher degree of freedom in CMF design. Just earlier this year, oppo had released a watch with a three-color oil pressure wristband. Through the mold, the blue layer, two translucent layer a total of three layers of strap prepared by oil pressure shaping, combined three into one. Taking into account the aesthetics, skin-friendly and comfortable touch, dirt and oil resistance and other characteristics. The three-color strap can be molded in one shot through the injection molding process, and can achieve multi-color, surface texture and other effects, making the product more cool and beautiful. In this article, let's learn more about it. Mainly include: I. Three-color watchband and production process ideas II. process flow analysis III. three-color injection molding related equipment and mold show IV. multi-shot implantation technology in the field of smart watches CMF Design Corps has set up a smartwatch CMF industry chain exchange group, aiming to gather a group of professional elites from upstream and downstream enterprises of the industry chain to do industry exchanges and resource docking around materials, design, process and development trend. Add CMFDESIGN008 to join the group, and note that you have to note "smartwatch" Oh~~!
