Part 1 The Cutting Tools Materials for Aluminum Alloy When machining Aluminum Alloy, if we dont choose the proper cutting tool materials, it usually has some problems, such as sticking cutters and chips removal, which will lead to the cuttin...

The carbon fiber composite material has high specific strength and specific rigidity. It is a composite material formed by using carbon fiber or carbon fiber fabric as reinforcement and resin, ceramic, metal, cement, carbon or rubber as the...

Part 1 The main advantages of PCD materials (1) The Hardness can reach 8000HV, is about 80~120 times of the cemented carbide ; (2) The thermal conductivity is 700W / mk,is about 1.5~9 times that of cemented carbide, even higher than that of...

Aluminum alloy are widely used for producing pistons because of its light weight, good Thermal conductivity and low Thermal expansion coefficient. Even the cutting force when machining aluminum alloy is smaller than that machining steel, th...

Part 1 The Materials of the Gearbox In past times, the gearbox is made of gray cast iron, which is easily forming, and has good shock absorption and low costs. With the usersincreasing requirements for driving comfort of the cars and the ma...
