Super hard abrasive coatings are most commonly used on resin-bonded grinding wheels, while nickel and copper are the preferred coating materials. Coating thickness depends on coating material. Copper coating usually accounts for 50 % of the total weight of coated abrasive particles. Nickel coatings accounted for 30, 56 or 60 percent of the total weight of the coated grains. The 56 nickel coating has a stronger grain holding force (longer holding time), but it also generates more heat. Silver can also be used as a grainy coating for resin-bonded grinding wheels, which, despite its high cost, has the desired lubrication properties. The silver-coated super hard grinding wheel is mainly used to grind the spiral groove of the cemented carbide drill bit.     2.Abrasive coating of metal and vitrified bonded grinding wheel The coating used for metal-bonded grinding wheels is metal-carbide base coating. The most common coating materials are titanium carbide and chromium carbide. The

Wheel shape: For chain grinding Outside diameter: 5 3/4" or 146,05 mm Abrasive layer thickness: 1/4" or 6,35 mm Bore diameter: 7/8" or 22,23 mm Free bushing (reducing spacer) included to fit arbor shaft 12 m

Diamond cutting wheels are used for efficient cutting of hard, short-chipping and wear resistant materials such as  glass, ceramics and carbide, graphite, quartz, ferrite and semiconductor materials.

Grinding in two steps: The first step: rough grinding, the grinding parameters are: abrasive grain size 125-150 mesh; grinding wheel RPM is 25-30m / s; workpiece RPM is 0.3m / s; grinding depth <0.01mm; moving speed 0.2-0.3 m/min, longitudinal feed amount 0.025-0.05mm The second step:fine grinding, the grinding parameters are: abrasive grain size 380-400 mesh, grinding wheel RPM 25-30m/s; workpiece RPM 0.5m/s; grinding depth less <0.005mm, moving speed 0.05-0.1m/s, the longitudinal feed rate is 0.025-0.05mm.

Vacuum blazed diamond grinding wheel In order to give full play to the role of diamond, it is necessary to increase the control force of bond on diamond and improve the bond strength of grinding wheel. Single-layer high temperature brazing super-hard abrasive grinding wheel can overcome the shortcomings of electroplating grinding wheel, and can realize chemical metallurgical bonding among diamond, binder and metal matrix, with high bonding strength, Only by maintaining the thickness of the combined layer to maintain the height of the grinding grains by 20% ~ 30%, the grinding grains can be firmly controlled by high-speed and efficient grinding with large load, so that the bare height of the grinding grains of the brazing grinding wheel can reach 70% ~ 80%. Thus, the chip space is increased, the grinding wheel is not easily blocked, and the abrasive is more fully utilized. Under the same processing conditions as electroplated grinding wheels, the grinding force, power loss and

Effect on diamond wheel hardness. The hardness of the grinding wheel refers to the ease with which the superhard abrasive falls off the grinding wheel. The harder the abrasive particles fall off, the higher the hardness of the grinding wheel.In general, the more the combined dose, the stronger the abrasive is held, the more difficult the abrasive particles fall off, and the higher the hardness of the grinding wheel. The grinding wheel has a bad cutting edge during grinding, which is prone to grinding.The life of the diamond grinding wheel will increase, but the surface of the composite sheet is prone to chipping. It is necessary to properly grind the grinding wheel to avoid grinding cause waste.     Effect on the content of binder and the bonding strength of diamond abrasive. The hardness of the composite sheet itself is very high. During the grinding process of the outer circle, the diamond on the surface of the grinding wheel is subjected to a large grinding force and im
