Grinding is a mechanical processing method that removes material. In a narrow sense, it refers to the processing method of removing excess material on the workpiece with an abrasive tool. Grinding wheels, superabrasive tools, grinding heads, mounted points, sand tiles, oilstones, abrasive belts, etc.

The diamond grinding wheel of #800(particle size 20 μm) can quickly remove the surface material of gallium oxide wafer without cleavage breaking, but the surface damage is serious and there are a lot of obvious microcracks. The surface quality of gallium oxide wafer grinding with diamond wheel 1000(grain size 16 μm) was significantly improved, and only a few microcracks were observed on the wafer surface. The ultra-smooth surface processing technology of gallium oxide wafer was determined by using #800 diamond grinding wheel, #1000 diamond grinding wheel and silica sol polishing solution successively.

One of the purposes of cutting tool sharpening is to obtain cost-effective cutting edge quality, and the key to quality is the choice of the size of the sharpening wheel. The finer the particle size of the grinding wheel, the smaller the chipping of the cutting edge, and the lower the grinding efficiency.

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.
