Spindle Conversions


Gunn Machine & Tool Co. can update your older style Morse or NMTB spindle taper to accept newer CAT style tooling. This is done by the installation of a special insert that utilizes the use of OTT drawbar system. The insert is similar to the ones we use to repair severely damaged spindles. The addition of a hydraulic system to unclamp and safety switches that will only allow clamping cycles only when the spindle is stopped completes the job.

This insert has been in service for over 8 years
