How to choose internal grinding Wheel?

Diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the workpiece will increase, which will increase the grinding heat and make cooling and row cutting difficult. If the diameter of the grinding wheel is too small, it is difficult to achieve the ideal grinding speed (30m/s~50m/s), which increases the grinding thickness, increases the conformity of the grinding grains, and is easy to blunt, which increases the surface roughness of the inner hole and reduces the production efficiency when grinding the hole of workpiece.

Dicing Blade selection for wafer cutting

At present, most of the wafer cutting is using high precision scribing machine, which is mainly mechanical processing.

Under the action of mechanical stress, the wafer is prone to quality abnormalities after cutting. Common quality abnormalities include: product surface, back Chipping, PAD oxidation, delamination, missing Angle and other abnormalities.

How to distinguish ND, MCD, PCD?

Diamond is mainly divided into single crystal system and polycrystalline system.
The single crystal system is divided into natural diamond ND and synthetic single crystal. Among them, synthetic single crystal is divided into artificial single crystal MCD and synthetic single crystal CVD.
The polycrystalline system is divided into polycrystalline diamond PCD and chemical vapor CVD.

Advantages of domed type PDC cutter and PDC bits for drilling gravel formations

Domed type PDC bits front teeth are non-planar cutters, the back teeth are conical teeth, the front row tooth composite plate adopts convex ridge structure design, which can effectively improve the impact resistance and wear resistance of the bit. Rear row compound conical teeth are conical cutting elements, which can effectively share the drilling load of the front row main cutters by participating in formation fragmentation, which is conducive to protecting the front row cutters and greatly improving the service life of the bit.
