Planetary Gear Case Study
Customer Profile: A Virginia-based machining and fabrication shop dedicated to supplying the heavy trucking industry with planetary gear cases.
Speed the process of reverse machining of planetary gear cases while maintaining high tolerances through heavy interrupted cut.
A Torque Bar Activated Autofacer® was used on a vertical CNC machining center at a rate of 275 SF/Min, .003 IPR. Ø3.638 spot face holding a ±.002 perpendicularity between front and back faces and through hole. Heavy interrupted cut.
The Autofacer® advantage elimintated a costly secondary broaching operation. Machining the front and back faces in one operation without indexing the part. Successfully maintained spot face and perpendicularity tolerances through heavy interrupted cut.
