What Is On-Site Machine Tool Repair?

On-site machine tool repair is service performed on your shop floor, where the machine is installed and running. Exact Machine Service performs machine assessment, and many repairs are completed on site when conditions allow. Services include spindle rebuilds, ball screw repair, 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 service technicians to your facility for on-site machine tool repair. The machine gets worked on where it sits. Our technicians bring diagnostic tools and hands-on experience to work toward getting your equipment back online. 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.

Spindle Rebuild and Replacement

Your spindle determines part quality. Vibration, poor surface finish, or dimensional problems usually trace back to spindle issues. Spindle rebuilds are completed to original manufacturer specifications through third-party rebuild partners.

  • Complete rebuilds:
    bearings, seals, and precision grinding as part of the work
  • Performance upgrades:
    higher RPM capability where the spindle design and machine support it, following a technical review
  • All 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 coordinates spindle rebuilds to original manufacturer specifications, performed by third-party rebuild partners. 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 cost
  • Assembly:
    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 faults
  • Parameter 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. Service vehicles carrying common tools and diagnostic equipment 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:
    service vehicles carrying common tools and diagnostic equipment, dispatched to your facility
  • Parts access:
    relationships with multiple parts vendors to help reduce repair time.

When you call with a breakdown, we assess the situation and dispatch the right technician. From there we diagnose the fault and recommend a repair plan. Some repairs are completed and tested on the first visit; others require parts or a return visit. You receive a follow up report.

Inspection, Calibration, and Laser Alignment

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 standards
  • Spindle runout testing:
    spindle condition verified with precision test equipment
  • Laser interferometry:
    linear positioning verified with professional laser measurement systems
  • Ballbar testing:
    circular interpolation and contouring performance assessed
  • Way and axis straightness checks:
    linear guideways and axis alignment evaluated

Documented calibration and verification reports are available for your internal quality records.

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 platforms
  • Servo and drive upgrades:
    updated drive systems for improved responsiveness
  • DRO installations:
    digital readout systems to assist with setup and positioning
  • CNC 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 demands
  • Routine service visits:
    structured evaluations that identify wear and alignment concerns
  • Corrective recommendations:
    smaller concerns addressed early to help limit larger repairs later
  • Service documentation:
    records that support maintenance tracking and quality system requirements

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 field service technicians experienced with 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.

Can a machine tool be repaired where it’s installed?

Yes. The machine stays where it is installed, and our technicians assess it on your shop floor. Many repairs are completed during that visit. When a job needs parts or specialized work, the repair is scheduled for a return visit, and individual components, such as a spindle, may be removed and sent out for rebuilding while the machine stays in place. Parts are sourced from vendors as needed.

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 and a repair plan is recommended. Depending on the issue, the repair may be completed and tested during that visit or scheduled once parts are available. You receive a follow-up report on the work performed.
