Grinding is the use of high-speed rotary grinding wheel grinding workpiece processing method, grinding and other cutting processing methods have the following characteristics:
1. High grinding speed, up to 30m ~ 50m per second; The grinding temperature is high, up to 1000℃ ~ 1500℃; The grinding process takes a very short time, only about a ten-thousandth of a second.
2. Grinding can obtain high machining accuracy and small surface roughness value.
3. The cutting depth during grinding is very small, and the metal layer that can be cut out in one stroke is very thin.
4. When grinding, a large number of fine grinding chips fly from the grinding wheel, and a large number of metal chips splash from the workpiece. Dust and metal shavings can cause damage to the operator's eyes, and dust can also be harmful if not inhaled into the lungs.
Grinding processing, in mechanical processing belongs to finishing, processing amount is small, high precision. In the machinery manufacturing industry is more widely used, after heat treatment quenching carbon tool steel and carburized hardened steel parts, in the grinding and grinding direction of the basic vertical surface often appear a large number of more regular arrangement of cracks - grinding cracks, it not only affects the appearance of the parts, more importantly, it will directly affect the quality of parts.
