Chinese made, for Colchester. We had one in the Cold Lake Machine Shop, and it was a very nice machine to run!
The CF 'used' to have a Section under the REME flag, that took care of basic Machine repairs and coordinating outside Contracters for repairs, but that all went away with the reductions in manning levels through the eighties and nineties. All that remained was the solid idea that "It's not our problem!", as far as doing basic maintenance and repairs, and I clashed regularly with my supervisors, when they caught me fixing things anyways... Nothing to make you feel the dumb, like having a guy drive up from Edmonton, so that you can point at the memory battery on the milling machine control, and hand him the part number, so he can drive back down, order the $15 part, and drive back up the week after to install same... Or having yourr boss inform you that you cannot change out the oil in the headstock, because it's "Not your job!"
It may be as simple as a shear pin, or a few stripped teeth on a gear, or it may have bent the headstock spindle or done damage in the drive for the carriage. A fella gotta use due dilligence and bring a dial indicator along while checking it out...
About the only negative thing I had to say about ours, was that the Constant Surface Speed unit that was part of the DRO (a C-80 CSS, Newall) did not ever work as advertised, and eventually the CSS controller was removed, on a Safety Recall, as it apparently did not play nice with the VFD, apparently causing uncontrolled movements of the spindle.
