Cylindrical grinding generally has longitudinal grinding, horizontal grinding and deep grinding three ways.

The hardness of CBN grinding wheel is too high: the grinding wheel with proper hardness should be replaced.

Whether it’s Apple, Samsung, or Huawei, smartphone screens are getting bigger and bigger, and the majority of smartphone screens are made of optical glass (made by grinding and polishing).

Gear industry is the basic industry of China’s equipment manufacturing industry, with high industrial correlation, strong employment absorption and intensive technology capital, which is an important guarantee for equipment manufacturing industry to achieve industrial upgrading and technological progress.

Rotary diamond dresser dressing grinding wheel is different from single point diamond dresser. Moresuperhard diamond roller is in contact with the working face of the whole grinding wheel width in the dressing process. The cut dressing method can be formed in one time, with short dressing time and high efficiency.

Bearing raceway grinding methods are divided into swing method, cut method and forming method. Among them, the cutting method is the most common. The method used is to dress the grinding wheel into the required raceway shape and then directly process the raceway shape by the cutting grinding wheel. The surface topography of the grinding wheel will be reflected on the machining surface. Therefore, the dressing accuracy of grinding wheel working surface is the key to affect the machining quality of bearing raceway.

Materials hard to grind refers to the material with poor grinding machinability during grinding.

Bearing steel is the steel used to make balls, rollers and bearing rings.  Bearing steel is also known as high carbon chromium steel, carbon content ω C is about 1%, chromium content ω Cr is 0.5%-1.65%.  Bearing steel is divided into high carbon chromium bearing steel, chromium-free bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel six categories.

The China Cutting Tools and Equipments Exhibition-2021 will be held in Suzhou International Expo Center from November 2 to 4, 2021.
