Machine Tool Services and Repair Support

Practical machine tool service for manufacturers that need accuracy, uptime, and the right repair path.

Locher, Inc provides machine tool service, repair, inspection, and support for manufacturing facilities that rely on CNC machines, machining centers, boring mills, lathes, and other production-critical equipment.


Our core services include on-site spindle taper grinding, boring mill replaceable spindle taper inserts, machine tool spindle rebuilding, headstock rebuilds, #50 CAT conversion cartridges, machine calibration and alignment, machine tool design and engineering, and preventative maintenance consultation.


When a machine shows runout, chatter, poor finish, sticking tools, taper damage, bearing symptoms, headstock concerns, boring accuracy issues, or alignment problems, Locher helps review the machine and determine which repair path should be evaluated first.
