HERMLE Product Lines We Repair
Our engineers are trained on the full HERMLE product range. Below are the major product families we service.
Hermle C-Series (C22, C32, C42)
Compact 3 and 5-axis machining centers widely used in Indian precision shops. Common issues include spindle thermal runaway, servo axis drift, and Siemens/Fanuc control board failures under high-cycle production rates.
Hermle B-Series (B65, B85, B95)
Large-format universal milling centers for aerospace and automotive component production. Frequently encounter spindle bearing wear, RAM head servo calibration loss, and electrical control cabinet failures in tropical Indian climate conditions.
Hermle UWF Series (Universal Work Frame)
Automated pallet changer and robotic loading systems integrated with Hermle machining centers. Repair focus includes pallet shuttle servo faults, rotary table encoder errors, and PLC communication interface breakdowns.
Hermle Spindle Drive Systems
High-frequency spindle drives (12,000 - 25,000 rpm) with integrated cooling and thermal monitoring. Typical failures involve frequency converter capacitor degradation, speed feedback sensor malfunction, and coolant ingress into motor windings.
Hermle Control Systems (Siemens Sinumerik / Fanuc)
CNC controls equipped with Siemens Sinumerik 840D or Fanuc 31i interfaces. Common repair scenarios include axis servo loop instability, tool changer communication loss, and firmware corruption after power interruptions.

Common HERMLE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HERMLE equipment arriving at our workshop.
- ✓Spindle thermal alarm and loss of spindle speed — Hermle spindles operate at high thermal load; coolant contamination, bearing play increase, or thermal sensor drift triggers protection shutdowns on Hermle drive electronics. Tropical Indian humidity and inadequate chip flushing accelerate bearing degradation.
- ✓Servo axis drift and position error accumulation — Hermle servo encoders and feedback modules suffer calibration loss under thermal cycling or humidity exposure common in Indian manufacturing plants. Loose encoder connectors and corroded resolver windings contribute to axis creep during long production runs.
- ✓CNC control board hangs and axis freeze-up — Hermle control cabinets (Siemens Sinumerik or Fanuc-based) suffer PCB corrosion and capacitor failure due to condensation in humid Indian shop floors. Power supply transients and inadequate surge protection cause control module crashes.
- ✓Pallet changer timeout and tool magazine communication loss — Hermle automated pallet and tool changers rely on encoder feedback and pneumatic sequencing. Encoder bearing wear, air supply contamination, and solenoid valve stiction cause timeouts and position errors in the changer indexing sequence.
- ✓Resolver feedback signal loss and axis servo faults — Hermle C-series and B-series machines use resolvers for axis feedback. Connector corrosion, resolver winding shorts, and broken shield cables in high-vibration areas cause intermittent servo faults and axis disable errors.
- ✓Spindle frequency converter overheat and frequency trip — Hermle spindle drives integrate 3-phase power conditioning with built-in cooling fans. Capacitor bank electrolyte drying, fan bearing failure, and inadequate cabinet ventilation in enclosed Indian machine shops trigger thermal shutdown and converter protection faults.

Frequently Asked Questions — HERMLE Repairs
Do you repair Hermle CNC machining centers across all of India?+
Yes. Synchronics maintains full technical capability for Hermle C-Series, B-Series, and UWF automated systems across India. We provide door-to-door pickup and repair from our Vadodara facility for customers in Mumbai, Delhi, Bangalore, Pune, Hyderabad, Chennai, Ahmedabad, and all other major industrial cities. Most repairs complete within 5-7 days.
What Hermle spindle drive problems can Synchronics fix?+
Synchronics repairs all Hermle spindle motor-drive combinations including HSK-A 25, HSK-E 32, and direct-drive spindles. We handle frequency converter faults, thermal sensor calibration, speed feedback issues, water-cooling circuit problems, and spindle bearing cartridge replacement. We test spindle runout and dynamic balance after each repair.
Can you repair Hermle machines with Siemens Sinumerik 840D controls?+
Absolutely. Synchronics has extensive experience with Siemens Sinumerik 840D-based Hermle control systems. We repair servo drive modules, servo amplifier PCBs, encoder interface boards, and coordinate system calibration. We also handle firmware updates and control parameter restoration if your machine suffered a crash or power failure.
How do I know if my Hermle spindle needs repair?+
Watch for thermal alarms, spindle speed loss under load, unusual vibration, coolant leakage, or grinding noise from the spindle housing. Also if you see servo axis freeze messages or position error codes after spindle operation, your spindle thermal management or feedback system likely needs attention. Contact Synchronics for a free diagnostic evaluation.
Do you offer Hermle preventive maintenance and calibration services?+
Yes. Synchronics provides annual spindle bearing preload inspection, servo encoder recalibration, control system software updates, and thermal sensor verification for Hermle customers. Preventive maintenance schedules significantly extend machine uptime and part life, especially critical for Indian manufacturers running high-volume production shifts. Call us for a maintenance plan tailored to your Hermle equipment age and usage.
How do I send my HERMLE unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HERMLE drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HERMLE repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HERMLE unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
