SERVICE, CHECKS-OUT and MAINTENANCE
Service, Calibration & Preventive Maintenance
TOS America provides warranty and after-warranty service for all Fermat horizontal boring mills, as well as machines from TOS Varnsdorf, Škoda, and other major European manufacturers. Our service programs are designed to maximize machine uptime, extend equipment life, and maintain the tight tolerances your production demands.
Service Centers on Four Continents
We operate service centers and parts warehouses in Canada, the USA, Europe, and India, supported by a network of local service technicians and certified partners in all major markets. This means faster response times and reduced travel costs for our customers.
4 regional service centers with local technicians
Typical on-site response within 48–72 hours in North America
Warranty and after-warranty coverage for all Fermat machine models
Preventive Maintenance Programs
Preventive maintenance is the most effective way to avoid unplanned downtime and preserve machining accuracy. Our standard maintenance program includes pre-emptive inspections every six months, covering all critical mechanical, electrical, and CNC systems.
What We Inspect and Calibrate
Geometry Verification:
Complete geometry check-out of the machine bed, column, spindle, table, and angle heads
Measurement and resetting of machine geometry to factory specifications
Precision Calibration:
Ballbar testing — circular interpolation accuracy measurement using Renishaw Ballbar QC20 or equivalent. This test identifies servo mismatch, backlash, stick-slip, and other positioning errors in approximately 10 minutes per plane.
Laser interferometer testing — linear positioning accuracy verification with resolution to 0.001 mm (1 micron). We measure full-travel accuracy on all linear axes.
Kinematic transformation calibration — using workpiece probes to verify and correct 5-axis machine kinematics, ensuring accurate simultaneous multi-axis machining.
Post-Crash Diagnostics:
Comprehensive diagnostics and correction after machine collision events
Full assessment of mechanical, electrical, and CNC system damage
Restoration of machine geometry and accuracy to pre-crash specifications
Machine Remote Diagnostics — 24/7 Monitoring
Every Fermat machine ships with built-in remote diagnostics capability, allowing our engineers to connect directly to your machine's CNC system from our service center.
How Remote Diagnostics Works
Your operator reports an issue via phone or email
Our engineer connects remotely to the machine's PLC and CNC system
Real-time analysis of error logs, parameters, and machine status
Immediate diagnosis and guided troubleshooting
Remote Diagnostics Performance
80% of PLC-related issues resolved remotely — without an on-site visit
Average response time: under 2 hours during business days
Immediate spare parts identification — if a physical part is needed, we confirm availability and ship the same day
Machine data backup — we maintain performance baselines that help predict failures before they occur
Maintenance Schedule Recommendation
| Interval | Service Type | Key Activities |
|---|---|---|
| Every 6 months | Preventive inspection | Geometry check, lubrication systems, coolant systems, hydraulics |
| Annually | Full calibration | Laser test (all axes), Ballbar test, kinematic calibration |
| As needed | Post-crash restoration | Complete diagnostics, geometry reset, component replacement |
| Continuous | Remote monitoring | PLC monitoring, error log analysis, predictive maintenance data |
