Mechanical processing technology type

Mechanical processing technology is mainly divided into two categories: cutting processing and pressure processing. Cutting processing includes core processes such as turning, milling, drilling,

grinding, boring, planing, pulling, inserting, and tooth surface processing. ‌‌‌

Core cutting technology

Turning and turning

The rotation of the workpiece forms the main cutting motion, and the tool moves along the axis to complete the machining. It is suitable for rotating surfaces such as outer circles/inner holes/

end faces/threads of shaft and disk parts, with an accuracy of IT6 level and a surface roughness of Ra0.1 μ m. ‌‌

Milling

rotary cutting tools are used for complex contour machining of flat surfaces, grooves, gears, etc. It is divided into forward milling (high cutting efficiency) and reverse milling (good

machining stability), with an accuracy of IT8-IT7 levels and a roughness of Ra1.6-6.3 μ m. ‌‌

Drilling and reaming

drill bits rotate to form holes (roughness Ra5-6.3 μ m), which can be improved to IT6 level accuracy (Ra0.4 μ m) with precision machining of reamers, suitable for batch hole

machining. ‌‌

Grinding High speed rotation of grinding wheel achieves precision machining (IT5 level accuracy, Ra0.025μm）， Mainly used for surface finishing of quenched steel parts and high hardness materials. ‌‌‌

Boring
Expand the accuracy of existing holes (up to IT7 level), suitable for high-precision inner hole machining of box type parts, and complement drilling to improve positional accuracy. ‌‌

Planing and slotting
Linear reciprocating motion for machining flat surfaces/grooves, high stability but low efficiency; Cutting is specifically designed for processing confined spaces such as keyways/polygonal holes. ‌‌

Pull cutting A multi tooth cutting tool can complete complex surface machining in one stroke, with an accuracy of IT7 level and high efficiency. However, the tool cost is high, making it suitable for large-scale

production. ‌‌ Gear surface machining adopts forming method (milling cutter) or expanding method (hobbing/hobbing) to process gears, and the accuracy is significantly affected by the rigidity of the machine

tool and the tool life.

Pressure processing and other techniques

Pressure processing: changing the shape of materials through plastic deformation, including casting, forging, stamping and other methods, suitable for blank manufacturing and batch part

forming. ‌‌

‌Special processing: such as laser cutting  and electrical discharge machining (processing superhard materials), breaking through the physical limitations of traditional cutting tools.
