Replacement of passivated sand. When the passivation time of 400# sand tool is more than 20 minutes, the sand needs to be replaced or redeployed.

The dicing blade used in wafer cutting is a missing link in China's semiconductor packaging industry chain, which has been dependent on import for a very long time.

In cutting processing, tool performance has a decisive influence on the efficiency, accuracy and surface quality of cutting processing.

As the saying goes: strong horse with strong saddle. In the modern manufacturing industry, major companies use a large number of advanced CNC machining equipment,

Due to its advantages of high hardness, high strength, low density and excellent mechanical properties, superrigid aluminum alloy is widely used in aviation, aerospace, rail transit and automobile.

Due to the high hardness and wear resistance of PCD tools, it is difficult for general machine tools to meet the precision requirements of its edge grinding.

Polycrystalline diamond (PCD) was produced in the 1970s by sintering with binder (cobalt, nickel and other metals) at 1,000 ~ 2,000 ℃ and about 50,000 ~ 100,000 atmospheric pressure using natural or s...

PCD tools is made of super hard material “poly-crystal diamond” and substrate (HSS or tungsten carbide) by special process.
