Gear manufacturer teach you the requirements of gear finishing after hot turning

Processing steps:

1.Card loading requirements

First, the base surface and non base surface of the workpiece are determined, then the non base surface of the workpiece is used as the positioning surface for clamping the workpiece, and the base surface side is processed first.

2.Aligning workpiece

a) There is no gap between the positioning surface and the support, and the quarter point runout of the outer ring end face of the base surface is within 0.1mm.

b) Align the workpiece with the outer circle of the tooth (black skin after heat), and align the quartering point. The specific requirements are as shown in Table 5:

3.Machining base

(1) The inner hole of the workpiece is survived, the inner ring end face and outer ring end face are survived, and the chamfer is survived.

(2) Turn the 20-30mm gear grinding alignment belt at the outer circle of the tooth part on the base surface, and the outer circle can be polished.

4.Processing non base surface

Turn over the surface and align the inner hole of the workpiece within 0.1mm. The end face of the inner ring of the lathe is survived and the chamfering is survived.
