Product Introduction

Heavy Duty Rack And Pinion.

(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

Numerical control can not only improve the machining accuracy, but also improve the machining efficiency. Numerical control gear and rack machining machine tools have a great trend to replace the traditional gear and rack machining machine tools.

2. Intellectualization

According to the stress, strain and temperature rise of the machine tool, the cutting process parameters of the machine tool, namely the cutting parameters, can be dynamically adjusted to ensure the machining accuracy of the workpiece and the cutting efficiency of the machine tool.

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

Due to the rapid development of computing technology and the continuous improvement of interpolation algorithm, the data processing and curve fitting accuracy of CNC system can reach a high level. The adoption of feedforward control, nonlinear control, fuzzy control, neural network control and other intelligent control methods has greatly improved the tracking response characteristics of servo system, thereby improving the machining accuracy of gears. The further reduction of the pulse equivalent of the servo system, the further shortening or complete replacement of the mechanical transmission chain, and the application of the automatic compensation function and error compensation function of tool wear also improve the machining accuracy of the gear rack to a great extent.
