Sabre CNC Vertical Grinding Center

The Cincinnati Machine Sabre computer-numerical-controlled (CNC) vertical grinding center is available for user research projects. It is on loan to the High Temperature Materials Laboratory as part of an in-kind contribution by Cincinnati Machine (a UNOVA Company) under the terms of a Cooperative Research and Development Agreement. This equipment was originally configured as a vertical machining center, and has been modified for high-speed grinding. Modifications include a variable-speed grinding spindle capable of 24,000 RPM and extensive modifications to the way covers to protect the machine from damage due to grinding swarf. The grinder is instrumented for force measurements.
