03 planing

Planing is a cutting method that uses a planer to horizontally reciprocate the workpiece horizontally. It is mainly used for the shape processing of parts. The accuracy of the planing process is IT9-IT7, and the surface roughness Ra is 6.3-1.6um. The planing motion consists of: the reciprocating linear motion of the workpiece is the main motion of the cutting, and the feeding motion is the linear intermittent motion of the tool.

Since there is a return empty motion in the main motion of the planing, and the reciprocating motion cannot be high speed, the productivity is low. Due to the characteristics of planing, planing is mainly used in single-piece and small-batch production, and is widely used in maintenance workshops and mold workshops.

Planing is mainly used to machine planes (including horizontal, vertical and inclined), and is also widely used for processing straight grooves, such as right angle grooves, dovetail grooves and T-shaped grooves. If appropriate adjustments are made and certain accessories are added, It can also be used to machine racks, gears, splines and busbars with straight forming surfaces.
