Gunn Machine & Tool Co. has designed a spindle taper insert, to repair machine spindles, such as, in large horizontal boring mills, when damage is more severe and cannot be repaired by grinding alone.

Inserts can be made for drawbolt or pull stud type retention systems.

The insert is repairable and replaceable should damage occur in the future.

Inserts may also be used in spindle conversions, to change form older style morse tapers to CAT style tooling. We also offer CNC repair & CNC machine repair.
