Our 4-Stage Rapid Restoration Protocol
Engineered to get your high-value production spindles and axes back into operation with zero guesswork.
Specialized services from emergency breakdown to micron calibration.
We don’t just temporarily clear alarm codes — we pinpoint root-cause failure mechanisms, restore OEM geometric tolerances, and extend machine operating lifecycle.
Emergency Breakdown & Troubleshooting
Rapid diagnostic resolution for servo alarms (Fanuc 401/414, Siemens 25201), spindle drive trip, PLC ladder faults, hydraulic pressure loss, lubrication failure, and axis overtravel locks.
Spindle Overhaul & High-Speed Servicing
Complete reconditioning of direct-drive, belt-driven, and built-in motorized spindles (BT30, BT40, BT50, HSK63). High-precision angular contact ceramic bearing replacement and dynamic balancing.
Ball Screw & Guideway Reconditioning
Elimination of axis backlash, axial play, and lost motion. Ball screw pre-load adjustment, support bearing replacement, linear guideway replacement, slide way Turcite-B scraping and alignment.
Laser Interferometry & Ballbar Calibration
Renishaw XL-80 laser pitch error compensation, linear positioning accuracy mapping, repeatability verification, and Renishaw QC20-W circularity & squareness diagnostic testing.
CNC Retrofitting & Control Upgrades
Modernizing legacy manual or obsolete CNC machines with latest Fanuc, Siemens, or Mitsubishi controllers, AC digital servo drives, high-resolution optical linear scales, and refreshed electrical panels.
Annual Maintenance Contracts (AMC)
Proactive, scheduled preventive maintenance contracts (Comprehensive & Non-Comprehensive). Quarterly geometry checks, vibration analysis, oil condition inspection, and priority 24/7 breakdown callouts.

Real feedback from production managers, plant engineers, and maintenance heads who rely on USHA CNC Solutions.
"USHA CNC responded within 2 hours to a critical VMC spindle crash. Their engineer replaced the BT40 bearing on-site and balanced it to G1.0. Production resumed same night. Absolutely professional and highly capable team."
"We had a Fanuc 414 alarm stop our aircraft bracket line at midnight. Usha CNC picked up the call immediately, diagnosed the faulty servo drive remotely and sent an engineer by morning. Tremendous expertise and commitment."
"Their Renishaw laser calibration service transformed our HMC's positional accuracy. We now hold ±0.003mm on a 600mm stroke — something we could never achieve before. Full ISO test certificate was provided."
"I have an AMC with Usha CNC Solutions for 3 machines. Their quarterly checks have completely eliminated surprise breakdowns. Best decision I made for my shop floor. Honest, skilled and always on time."
"We had severe surface chatter on our double column mill. Usha team did crossrail leveling, turcite scraping and spindle rebalancing. The finish quality is better than when the machine was new. Exceptional work!"
"Very responsive team. They handled our floor boring machine's ram droop issue professionally. Job took a day longer than estimated, but the final quality was perfect with micron-level geometry verification report."
