On-Site Machine Tool Repair
On-site machine tool repair from Exact Machine Service. Spindle rebuilds, ball screws, CNC troubleshooting, and calibration on site.
What Is On-Site Machine Tool Repair?
On-site machine tool repair means the work happens at your facility rather than at a repair shop. Exact Machine Service performs machine assessment and many repairs are completed on site when conditions allow. The scope spans spindle rebuilds, ball screws, CNC troubleshooting, motor and drive support, and calibration.
Modern manufacturing depends on reliable machinery. When a breakdown hits, production stops and the clock starts. Exact Machine Service sends field engineers to your facility for on-site machine tool repair. The machine gets worked on where it sits. Our engineers arrive with the tools and the experience to get equipment back online. The work spans spindle rebuilds, ball screw replacement, CNC troubleshooting, motor and drive support, inspection, calibration, and laser alignment. Emergency breakdowns and scheduled repairs both run through the same team. Tell us the make, the control, and what the machine is doing, and we take it from there.
Contact us for machine tool repair servicesSpindle Rebuild and Replacement
Your spindle determines part quality. Vibration, poor surface finish, or dimensional problems usually trace back to spindle issues. We rebuild spindles to original specifications or better.
Complete rebuilds:
bearings, seals, and precision grinding as part of the workPerformance upgrades:
higher RPM capability when your application calls for itAll spindle types:
belt drive, direct drive, and motorized spindles
Our team has supported spindle rebuild projects across a range of equipment, from knee mills to machining centers.
Why Is My CNC Spindle Making Noise or Leaving a Poor Surface Finish?
Vibration, poor surface finish, and dimensional problems usually trace back to the spindle. Your spindle determines part quality, so those symptoms are worth chasing early. Exact Machine Service rebuilds spindles to original specifications or better. Bearings, seals, and precision grinding are part of the work.
Ball Screw Repair and Replacement
Worn ball screws create backlash and positioning errors. Parts come out wrong and setup time increases. Our technicians repair and replace ball screws to bring the machine back toward its tolerance spec.
Replacements:
new ball screws when repair is not worth the costAssembly:
professional installation with proper preload settings
CNC Troubleshooting
CNC system failures can disrupt production and may occur without warning. These issues range from control alarms and servo faults to parameter or program concerns. Our technicians use structured diagnostic procedures to isolate the fault and work through it.
Systematic troubleshooting:
methodical diagnostics to identify the source of CNC faultsParameter support:
backing up, reloading, and verifying machine parameters after system issues
Our team carries diagnostic tools compatible with many major CNC platforms. We work to resolve issues efficiently, often during the initial visit when conditions allow.

How Quickly Can Someone Get On Site for an Emergency Machine Breakdown?
Priority is given to urgent service requests based on availability. Fully equipped service vehicles are dispatched to your facility, and scheduling depends on availability and location. Many repairs are completed on site when conditions allow. Give us the make, the control, and the symptom when you call.
Emergency Breakdown and On-Site Machine Tool Repair
Production equipment often fails without warning. These disruptions tend to arrive when orders are big and deadlines are tight.
Mobile service:
fully equipped service vehicles dispatched to your facilityParts access:
extensive inventory reduces repair time
When you call with a breakdown, we assess the situation and dispatch the right technician. From there we diagnose the fault, repair the issue, and test the machine. You receive a follow up report.

Machine accuracy plays a role in part quality and repeatability. We provide inspection, calibration, and alignment services to help verify and improve machine performance.
Geometric evaluation:
machine geometry measured against available specifications and industry standardsSpindle runout testing:
spindle condition verified with precision test equipmentLaser interferometry:
linear positioning verified with professional laser measurement systemsBallbar testing:
circular interpolation and contouring performance assessedWay and axis straightness checks:
linear guideways and axis alignment evaluated
Documented calibration and verification reports are available to support internal quality systems and compliance requirements.
Machine Tool Upgrades
If your mill or lathe is not performing as you want, replacement may not be the only option. In many cases, targeted upgrades can extend service life and improve reliability.
Control retrofits:
outdated controls replaced with modern CNC platformsServo and drive upgrades:
updated drive systems for improved responsivenessDRO installations:
digital readout systems to assist with setup and positioningCNC conversions:
select manual machines converted to CNC operation where appropriate
Preventative Maintenance Programs
Consistent maintenance plays a part in machine reliability and production planning. Scheduled service during planned downtime can help reduce unexpected disruptions.
Flexible scheduling:
maintenance coordinated around your production demandsRoutine service visits:
structured evaluations that identify wear and alignment concernsCorrective recommendations:
smaller concerns addressed early to help limit larger repairs laterService documentation:
records that support maintenance tracking and quality system requirements
Why Choose Exact Machine Service for On-Site Machine Tool Repair
We support a wide range of machine tools, including older equipment, lesser known brands, and complex systems. That means practical options when service choices are limited. Our field team brings extensive experience across mills, lathes, EDMs, and fabrication equipment.
Frequently Asked Questions About On-Site Machine Tool Repair
What causes backlash in a CNC machine?
Worn ball screws are a common cause. As the screw wears, backlash and positioning errors follow, parts come out wrong, and setup time climbs. Exact Machine Service repairs and replaces ball screws, with proper preload settings on installation. The aim is to bring the machine back toward its tolerance spec.
Can a worn ball screw be repaired, or does it have to be replaced?
Both are options. Our technicians repair ball screws where that makes sense. New ones go in when repair is not worth the cost. Installation includes proper preload settings. The decision comes down to the condition of the screw and what the machine needs to hold.
Who can troubleshoot a CNC control alarm on an older machine?
Exact Machine Service has trained engineers specializing in a wide range of CNC controls. The team supports older equipment and lesser known brands. Diagnostic tools work with many major CNC platforms. Structured procedures isolate control alarms, servo faults, and parameter or program concerns.
Is it possible to fix a machine tool without shipping it out?
Often, yes. Machine assessment is performed at your location, and many repairs are completed on site when conditions allow. Field engineers arrive with diagnostic tools and parts access. Work that cannot be finished in the field moves to a scheduled window.
What happens when you call in a machine breakdown?
We take the call and assess the situation, then dispatch the technician who fits the machine and the control. From there the fault is diagnosed, the repair is made, and the machine is tested. You receive a follow up report on the work performed.
