CNC deep hole internal grinder processing process and high hardness

May 24, 2019

Widely used in the mechanical manufacturing industry, heat-hardened quenched carbon tool steels and carburized and hardened steel parts often have a large number of regularly arranged crack-grinding cracks on the surface perpendicular to the grinding direction during grinding. It not only affects the appearance of the part, but more importantly it directly affects the quality of the part.

The CNC deep hole internal grinder uses a high-speed rotating grinding wheel to machine the surface of the workpiece. Grinding is used to machine the inner and outer cylindrical faces, conical faces and planes of various workpieces, as well as special and complex forming surfaces such as threads, gears and splines.

CNC deep hole internal grinder is self-sharpening due to the high hardness of abrasive grains. Grinding can be used to process various materials, including hardened steel, high-strength alloy steel, hard alloy, glass, ceramic and marble. Contour hardness of metal and non-metallic materials. The grinding speed refers to the linear speed of the grinding wheel, which is generally 30 to 35 m/s. When it exceeds 45 m/s, it is called high speed grinding. With the development of high-efficiency grinding such as slow-feed grinding and high-speed grinding, parts can be directly ground from the blank. Grinding is also useful as a waste processing, such as grinding the riser of a casting.
