Product Overview

This custom PEEK helical gear combines a helical tooth profile with a stepped hub and D-shaped bore. CNC machining is used to create the functional relationship between the gear teeth and the torque-transmitting bore, followed by deburring to protect handling and assembly edges.

Helical Tooth Geometry Control

The helical teeth form a three-dimensional surface, so tooth direction, helix angle, and profile consistency must be controlled together. Process planning focuses on stable fixturing and a tool path that follows the tooth surface consistently, helping reduce variation that could affect mesh smoothness and transmission noise.

PEEK Cutting and Bore Alignment

PEEK retains heat while cutting, so cutting conditions need to limit heat buildup that can discolor or damage the material surface. The D-shaped bore is treated as a functional torque-transfer feature. Its positional relationship with the helical teeth is controlled from a repeatable datum so that clamping offset does not introduce uneven meshing or load distribution.

Project Value

For PEEK helical gears, the key decision is not only the material choice but also whether the tooth surface and drive bore are controlled from a shared machining reference. This approach helps protect assembly fit, torque transfer, and stable gear engagement while avoiding avoidable surface damage during machining.
