Peeling grinding usually uses a CBN wheel with a width of 4-6mm or so, and a 10-15°chamfering area is set in the abrasive layer. Its width is generally 1-2mm, and the width of the outer circular part is 3-5mm.

The cemented carbide matrix overcomes the shortcoming of hard and brittle polycrystalline diamond and improves the impact resistance toughness of the whole product. The easy weldability of cemented carbide solves the problem that the polycrystalline diamond is difficult to be combined with other materials by welding method, and the polycrystalline diamond composite sheet can be vertically inlaid on the drill bit. MORE SUPERHARD PDC cutter can help you get better results.

Most of the CBN grinding wheel substrate is made of metal, and when the CBN grinding wheel is grinding, most of the heat energy will be transmitted to the direction of the grinding wheel. Therefore, in the grinding process, heat energy will be continuously transferred to the grinding wheel. The metal matrix then begins to expand as heat accumulates.

Copper has good ductility, it is easy to cause blockage of pores, and the grinding wheel loses heat dissipation capacity, which in turn causes burns or expansion and deformation of the workpiece, which is one of the materials that are difficult to grind.

The grinding mechanism is completely different with cutting.

In cutting,using the tool cut into workpiece material so the material deforms then breaks.

Vitrified diamond grinding wheel not only has the wear resistance of metal bond and the porosity of vitrified bond. There are many advantages: high abrasion rate, minimal bond/workpiece interaction, excellent chip and coolant carrying capacity, good sand fixation ability and tool life, reduce surface damage to the self-sharpening behavior of the work piece, and change the grinding wheel Grit Selection and customization of hole structure.

Most of the vitrified diamond grinding wheels we produce are used for the grinding and polishing of precision PCD tools. Generally, the quality of the cutting edge of PCD tools requires 50 times magnification without chipping, and the high requirements are 200 times magnification without chipping, Even 5 μm edge accuracy

Cylindrical wheels is used for grinding and finishing of thermal spray coatings ( including tungsten carbide , chrome carbide and chrome oxide ), ceramics, carbides, chilled iron composites and other hard-to-grind materials.

Peeling grinding is a process that combines the durability and efficiency of CBN wheel with the superior performance of high speed grinding.

The accuracy of the work piece depends largely on the consistency of the process system state.After dressing the layer thickness decreases and the grinding wheel local changes to the designated calibration position, which leads to the change of the state of the whole process system, so the size consistency cannot be guaranteed.Therefore, it is very important to compensate the grinding wheel after dressing.
