Why Does a Gear Shaping Machine Produce Straight and Cross Waviness During Machining?

Section 1: Straight wave patterns appear on the gear surface

Mostly due to the poor rigidity of machine tool cutting tools and workpiece coefficients, a certain frequency of vibration is generated during the gear rolling process.

Machine tool-related factors include:

Due to the wear of the abrasive washer on the blade shaft's axial direction, the axial gap of the blade shaft has become excessively large, resulting in excessive axial movement of the blade shaft.

Due to the wear on the cone sleeve supporting the roller knife shaft, the clearance has become excessive, resulting in the roller knife exceeding the radial roundness tolerance.

Surface finishing with transverse wave patterns on gear teeth

The saddle slider strip on the knife holder has worn out and been readjusted to be too tight.

2. The vertical feed screw of the tool holder exceeded the installation precision.

3. The workbench cone guide rail has uneven wear and is too tightly fitted.

4. Vertical feed screw and indexing worm thrust bearing damage on the tool holder.
