Diamond grinding wheel is a better choice for grinding hard alloy, optical glass, ceramics, gem and stone materials with high hardness and high brittleness. However, diamond is not suitable for grinding steel because it is easy to carbonize at 700℃~800℃. The hardness of CBN is slightly inferior to diamond, but it has good thermal stability (can withstand 1300℃~1400℃ high temperature), CBN is not like diamond in high temperature, that is, oxidation and grapitization, and iron group elements chemical inertia, high thermal conductivity, with its production of grinding wheels long life (up to corundum grinding wheel dozens of times to more than 100 times), It is a better choice to replace hardened steel, high speed tool steel, bearing steel, stainless steel, heat resistant steel and titanium alloy and other metal materials with high hardness and toughness.

Silicon nitride ceramics have the characteristics of high strength and high temperature resistance. Among the ceramic materials, its comprehensive mechanical pr

Through laser welding technology or cold forming technology, the sintering section is fixed on the matrix, with high strength and strong anti-interference ability. The matrix has different holes, which is convenient to clean the residual rough material and increase the cooling effect of diamond grinding wheel.
Application of diamond grinding wheel for concrete and stone industry：
Used for grinding and polishing granite, marble, cement concrete, water flat, floor tile, tile, and other stone industry. Perfect for fast grinding and rough deburring.

Gear processing process:
1. Forging gear blank
2. Normalized:
The purpose of this process is to obtain hardness suitable for the cutting of rear sequence gear and to prepare the structure for the final heat treatment to effectively reduce heat treatment deformation. The gear steel used is usually 20CrMnTi.
3. Turning processing
In order to satisfy the high precision positioning requirement of gear machining, gear blank processing all adopt numerical control lathe, using mechanical clamping not heavy ground vehicles Under the knife, realized in a clamping aperture, end face and outside processing synchronization is complete, not only ensure the inner hole and end face of the vertical degree requirements, and ensures that the size of the discrete small gear billet production in large quantities. Thus the precision of gear blank is improved and the machining quality of rear sequence gear is ensured .

In order to meet the requirements of surface quality and machining accuracy of stainless steel parts, grinding is usually used. 

Due to the high toughness, low thermal conductivity and small elastic modulus of stainless steel, there are often the following problems in grinding:

1. Grinding wheel is easy to stick and jam.

2. The processing surface is easy to burn.

3. Work hardening phenomenon is serious.

4. The workpiece is easy to deform.

Generally, the dicing blade is made of synthetic resin, copper, tin, nickel and so on, which are combined with artificial diamond as binder. It is mainly divided into two categories: hard cutter with wheel hub and integral cutter without wheel hub. It is suitable for processing chips and semiconducting materials of different types.
