| Description |
| This machine was recontrolled with a Fanuc 15MB CNC in roughly 1999. It is currently an operational machine and is in good condition. We are offering this machine with a compete recertification done by our expert technicians. We will install our latest SFPS Gear hobbing software, and update the PLC logic to add additional error detections and safety. The machine will be tested to verify that it performs all the available cycles and that the axes repeat, and are geometrically accurate. Additional checks and repairs can be done if requested. |
