Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, and in particular relates to a CNC gear chamfering machine. Background Technology

[0002] Chamfering is an important process in gear manufacturing. It can remove burrs and sharp corners from gear edges, effectively reduce quenching cracks, reduce stress concentration, reduce gear meshing noise, and improve gear meshing quality and life.

[0003] Currently, most gear chamfering devices on the market use a clamping mechanism to hold the gear and then use a floating cutter to chamfer it. Due to the limitation of its fixed method, this method cannot chamfer both sides of the gear at the same time, resulting in low efficiency. In addition, its processing angle is relatively fixed, which cannot process gears with different tilt angles, thus limiting its applicability and increasing the production and processing costs for enterprises.
