CNC Grinding Machine Repair and On-Site Field Service
When your grinder is down, every hour costs you parts. MMS field technicians repair CNC grinding machines on-site across the United States, Canada, and Mexico, backed by 40+ years of hands-on precision grinding experience.
Every repair starts with a methodical diagnostic process: mechanical inspection, electrical checks, and full system verification. Whether it is testing and cleaning linear scales on a Jones & Shipman, realigning a Kellenberger workhead after a crash, or swapping a complete B axis on a Studer, we work from manufacturer specs and real field data, not guesswork.
Our technicians are based in the Northeast, Midwest, and Southeast and travel nationwide. Same-day response is available for production-down emergencies during business hours, and we routinely overnight critical parts to compress your downtime.
Common repair scenarios our customers call us on
Servo drive alarms and parameter loss after power events.
Axis scale, encoder, and linear scale alarms that fail intermittently.
Unresponsive or intermittent electrical issues that shop electricians cannot localize.
Profibus alarms that drop drives or peripherals out of the network.
Workhead, tailstock, or B-axis alignment problems after a move, crash, or rebuild.
Hydraulic and hydrostatic pressure faults causing axis inhibit on startup.
What sets MMS apart on a grinder repair
Grinder-specialist technicians, not general machinery generalists. Most of our team trained on Kellenberger and Hardinge platforms before MMS.
Direct OEM relationships and authorized reseller status for HEIDENHAIN and Elaso means parts arrive on faster lead times than generic third-party sourcing.
One vendor for diagnosis, parts, and installation. You get one invoice, one technician trail, and one accountable owner of the repair.

Frequently asked questions
How quickly can you get a technician on site for a production-down grinder?
For urgent production-down calls during business hours, MMS responds within two hours and dispatches a field technician to the nearest qualified engineer. We routinely arrive next-business-day in the Northeast, Midwest, and Southeast and within 48 hours nationwide.
Do you repair grinders from manufacturers no longer in business?
Yes. Legacy and orphaned grinders are a significant share of our work. With 200+ years of combined experience and cross-reference part sourcing, we routinely keep Tschudin, Voumard, Tripet, Gioria, and other legacy brands in production.
Can you diagnose remotely before sending a technician?
Yes. For many control and electronics faults we can guide your maintenance team through diagnostic steps by phone, narrow the failure, and arrive with the right parts in hand instead of making two trips.
