  • The Difference Between A Natural Diamond And A Synthetic Diamond

    Synthetic diamond is the artificial stimulation of natural diamond formation conditions so that the non-diamond structure of carbon into the diamond structure of carbon. To put it simply, the raw material of graphite powder is transformed into the diamond structure through high temperature and high-pressure processing.There are two main types of artificial diamond manufacturing processes that we can achieve today: high-pressure high temperature (HPHT) and chemical vapor deposition (CVD). Since the first successful use of high-pressure and high-temperature diamond production methods in 1950, this method has gradually been promoted in many countries. Gem-quality synthetic diamonds produced using this method are now mainly in China, Russia, the United States, and other countries.Difference Between A Natural Diamond And Synthetic Diamond1. The valueThere is not much difference in appearance between synthetic diamonds and natural diamonds. But in terms of value, synthetic diamonds of the same quality are much cheaper than natural diamonds. Some synthetic diamonds cost only a fifth of the price of natural diamonds. The value of natural diamonds on the market is relatively stable and sustainable, and there may be greater production value in the future.2. Colour and lusterBoth natural and synthetic diamonds are made of carbon atoms and are arranged in the same lattice, so they have the same physical properties. The only feature is irregularities or defects in the micro and atomic lattice. In this regard, natural diamonds and artificial diamonds are no different due to different growth environments, such as chemical atmosphere and growth rate. Most artificial diamonds on the market today are very strong yellow, orange, and brown, while natural diamonds are transparent and easy to distinguish.

But also the processing of small hardware, scraper for papermaking machinery, bending machine mold, plastic mechanical cutting edge, mower cutting edge, cutting machine cutting edge, harvester cutting edge, and processing of some small parts plane and so on. Its electromagnetic chuck can design to adjustable in angle or fixed, so its use is very extensive. Some applications are recommended by users. We can make various special specifications according to user requirements. Grinding machines such as grinding machines, grinding machines, etc. Safety instructions for the sharpening machine As a high-precision grinding machine, we must pay attention to the standard operation when using the Micra-10 sharpening machine to prevent accidents. Below Demina has sorted out the safe operation of the sharpener and hopes to help you. First, check whether the grinding wheel is tight and eccentric before using the sharpener to sharpen the knife. If cannot meet the user requirements, be sure to adjust and use them. In addition, safety measures such as protective glasses must be worn when sharpening the knife. It is strictly forbidden to adjust the locking tool holder when the grinding wheel is running. If it needs to adjust, it must stop the grinding wheel. Also, in the process of sharpening the knife with a sharpener, it is important to remember that the feed of the tool in the direction of the grinding wheel should not too large. In addition, the Micra-10 small drill grinding machine requires different grinding wheels for the grinding of different tool materials. It is strictly forbidden to grind high-speed steel tools on the alloy grinding wheel. The general-purpose grinding wheel is a resin grinding wheel, and the common grinding machine is used. Accessories must place in a designated position, and tools that cannot be repaired must be disposed of. The sharp situation of sharpening machine 1. Operate with a small amount of force, but both hands are raised. And the practice of sharpening the point of view also increases, only grinding the edge of the blade, but not the blade. Because the operation of the sharpener is very small, even if it happens by chance, as long as it is a micro-cut. The blade will not form an early roll, but it also constrains the sharp progress. 2. Both hands are reduced, the practice sharpening point of view is reduced. No matter whether the force is applied, the edge and the blade face can not ground, only the inner edge line can ground. In this case, the edge line will be rounded. However, there is no harm to the cutting edge. 3. Adhere to the Micra-10 sharpening machine height of the blade ridge is unchanged. And the hand pressing the blade is unstable due to instability, and the blade is suddenly sinking. Because of the elastic deformation, the sinking of the blade caused the tip to lift 2.620. The practice sharpening point of view dropped to 22.210. The added force is transferred to the inner edge line through the blade, although this will cause the edge line to be rounded and untidy, it is useful to maintain the edge. 4. Adhere to the height of the knife sharpener and the hand of the knife is unstable, causing the blade to tilt. Because of the elastic deformation, the ridge of the blade not only does not increase the point of view of the sharpening but makes the tip of the blade lift up 1.323. The sharpening point of view is reduced to 23.899. The situation is extremely similar to the third condition and can also maintain the cutting edge. 5. Because the oil stone is not smooth, and the particle size is not uniform. The blade will be impacted from time to time, the blade body's elastic deformation will make the blade upturn, and then avoid or reduce the direct impact on the cutting edge, which is conducive to the improvement of sharpness.

  • Selection Of PCD Tool Sharpening Equipment

    PCD Tool Sharpening EquipmentIn order to improve the cutting efficiency of PCD tools, the cutting equipment needs to have certain conditions, mainly manifested in the following aspects:1. Enough rigidity and stability: because the grinding material hardness is very high, there is no certain pressure between the grinding wheel and the grinding part can not be removed PCD tool material. Therefore, the sand wheel shaft and other mechanisms must have enough rigidity. In addition, the spindle power should large enough, should not less than 1kW, recommended to use 2kW.2. Unique wheel tilting mechanism: unlike general tool grinding machine, special tool grinding machine used grinding wheel rack for transverse swing, to prevent caused by grinding wheel wear than low grinding wheel surface groove, bearing, precision grinding machine should be used precision guide rail and precise belt drive system. In order to avoid the grinding wheel on the tumbler to produce small jitter and affect the quality of blade.3. Adjustable grinding force: according to the difference between the processed tool and the grinding wheel, the grinding pressure should be adjustable at constant pressure. The purpose of adjusting the grinding force is to compensate for the change of grinding force between the grinding wheel and the contact area of the workpiece.4. High precision rotary table system and optical projection device on more advanced tool grinding machine are usually with optical projection equipment and high precision rotary table, so that after an outfit card, not only can grind the edge, and can accurately grinding tool arc between the two edges, and can through projection device on the machine tool directly observe arc and edge quality.5. Coolant can be fully supplied: the cooling system should have a flow rate of at least 20L/min, and an aqueous solution with an anti-rust agent is usually used as the coolant.Demina produces PCD tool sharpening equipment.
