CNC Maintenance and Repair

CNC Maintenance & Repair Services

Protect Uptime. Preserve Accuracy. Control Your Costs.

At Precision Service Machine Tool Rebuilders, we’ve been keeping CNC equipment productive since 1983. From our facility in Addison, Illinois—and through on-site service—we help manufacturers get more life, accuracy, and reliability from the CNC machines they already own.

When a CNC starts throwing alarms, drifting out of tolerance, or producing poor finishes, you need more than a reset. You need a service partner who understands the whole system—mechanical, electrical, hydraulic, and CNC control—and can get it running right again.

Our CNC Maintenance & Repair Capabilities

Preventative maintenance programs

Custom PM schedules for your machines, hours, and environment.

On-Site Troubleshooting

Diagnosis of alarms, axis issues, control faults, and part-quality problems.

Mechanical repairs

Ballscrews, spindles, bearings, couplings, gearboxes, way covers, and more.

Servos, drives & motors

Repair or replacement of servos, drives, encoders, feedback devices, and spindle motors.

CNC control & electrical

I/O faults, cabling, boards, power supplies, switches, relays, and wiring.

Hydraulic, pneumatic & lubrication systems

Pumps, valves, cylinders, actuators, lube systems, and filtration.

Alignment & accuracy

Leveling, squareness, backlash correction, pitch compensation, and test cuts.

Cleaning & system recovery

Coolant tank and line cleaning, chip removal, and contamination control.

Service documentation

Findings, completed work, and recommendations for future maintenance.

The result: CNC machines that hold tolerance, produce good finishes, and stay in production.
