Grinding Process

What is grinding process?

Grinding process is also known as grinding machining.

Grinding is machining the surface of metal parts by grinding wheel,oil stone and abrasive.

Machined parts with grinding process
The machine tool that uses grinding wheel is usually called grinding machine,the machine tool that uses oil stone and abrasive is called precise grinding machine.

The grinding wheel is a cutting tool with a lot of small and extremely hard abrasive particles.From its cutting action,each of the fine grinding granules on the surface of grinding wheel, the effect is equal to a subtle blade.grinding machining just like countless subtle blade cut at the same time.

In grinding process,blunt the edges of the grinding grain,since the effect of cutting force,It often breaks or falls off to reveal a new sharp sharpen,This kind of the phenomenon is called self -sharpness of grinding wheel.

The abrasive grinding process produces a lot of heat,So we need to cool down with a lot of flowing cooling water.

The range of grinding is very wide,almost any surface can be machined with grinding,such as inner and outer cylinder,Internal and external cone,kinds of plane,the screw thread,gear, spline, forming surface.Further more,it is hard to process hard materials such as hardened steel and hard alloy.
Due to the multiple blade and self-sharpness of grinding wheel, high cutting speed and The grinding machine has high precision,the precision and surface finish of metal parts are high after grinding,The average grinding precision reaches grade 1-2, the roughness can meet Ra0.4-Ra0.8, for precise grinding parts,the surface roughness can meet Ra0.05.

At present, the grinding process is generally used as the finishing process of parts surface.However, it can also be used for rough processing of pre-processing and cleaning works.
