Grinding
Grinding refers to the processing method of using abrasives and abrasive tools to remove excess materials on the workpiece. It belongs to the finishing industry and is widely used in the machinery manufacturing industry.
Grinding is usually used for semi-finishing and finishing, with an accuracy of IT8-IT5 or higher, and the surface roughness is generally 1.25-0.16μm.
1) Precision grinding surface roughness is 0.16-0.04μm.
2) Ultra-precision grinding surface roughness is 0.04-0.01μm.
3) The surface roughness of mirror grinding can be less than 0.01μm.
Drilling
Drilling is a basic method of hole machining. Drilling is often carried out on drill presses and lathes, or on a boring machine or milling machine. cnc milling part
Drilling has a low processing precision, generally only achieves IT10, and the surface roughness is generally 12.5-6.3μm. After drilling, reaming and reaming are often used for semi-finishing and finishing. cnc maching part
Boring
Boring is an internal diameter cutting process that uses tools to enlarge holes or other circular contours. Applications range from semi-roughing to finishing. The tools used are usually single-edged boring tools (called masts).
1) The precision of the boring of steel materials is generally up to IT9-IT7, and the surface roughness is 2.5-0.16μm.
2) The precision of precision boring can reach IT7-IT6, and the surface roughness is 0.63-0.08μm. anodizing part
