(1) Clamping of workpiece: when machining long rack like M5 gear rack, due to insufficient horizontal movement distance of the worktable of the milling machine, the longitudinal movement distance of the worktable must be divided, that is, the positioning reference surface on one side of the workpiece is required to be parallel to the longitudinal feed direction of the worktable. The workpiece can be directly pressed on the worktable or clamped with a special fixture.  

(2) Installation of milling cutter: when processing the long rack like M5 gear rack, the tooth pitch is controlled by the longitudinal lead screw of the worktable. Therefore, the direction of the original milling cutter rod on the horizontal milling machine cannot meet the processing requirements. The direction of the milling cutter rod must be parallel to the longitudinal feed direction of the worktable. Therefore, the spindle of the milling machine must be refitted.

The development of M5 gear rack processing technology is in the continuous pursuit of improving machining accuracy and machining efficiency, which is specifically reflected in the following aspects:

1. Numerical control

2. Intellectualization

3. High speed

For small module gear and rack, due to the advent of high-performance gear and rack machine tools and the improvement of tool performance, the cutting speed has been greatly improved. The cutting speed of gear hobbing machine can reach 90m/s; The number of strokes of gear shaper can reach 2000 times / min.

4. High precision
