CHEVALIER Product Lines We Repair
Our engineers are trained on the full CHEVALIER product range. Below are the major product families we service.
Chevalier VMC Series (Vertical Machining Centres)
CNC vertical machining centres ranging from compact 3-axis to advanced multi-axis configurations. Common electronic faults include servo amplifier failure, spindle encoder dropout, tool changer malfunction, and coolant pump controller issues affecting production cycles.
Chevalier HBM Series (Horizontal Boring Mills)
Heavy-duty horizontal boring mills for large aerospace and automotive forgings. Typical repairs include rotary table encoder failure, X-Y-Z axis servo drive burnout, main spindle brake control faults, and pallet positioning system errors in high-precision boring operations.
Chevalier Surface Grinder Series
Precision surface grinding machines for finishing operations on cast iron, steel, and aluminium components. Electronic failures commonly involve magnetic chuck power supply collapse, spindle speed control instability, infeed servo malfunction, and coolant system pressure transducer faults.
Chevalier CNC Control Systems & Servo Electronics
Integrated CNC control modules, servo amplifiers, and motion control boards managing axis movement and spindle regulation. Frequent faults include MOSFET burnout in servo drives, control board capacitor aging, encoder signal loss, and communication protocol errors between motion controller and peripheral devices.
Chevalier Spindle Motor & Drive Assembly
High-speed spindle motors (up to 10,000 RPM+) with integrated cooling and bearing systems. Repair needs include thermal runaway, bearing preload loss, encoder misalignment, variable frequency drive (VFD) communication loss, and winding short-circuit detection.
Chevalier Axis Servo Drive & Motor Assembly
AC servo drives and motors powering X, Y, Z axes and auxiliary spindle functions. Common failure modes include over-current shutdown due to mechanical binding, encoder resolution mismatch after retrofits, coolant contamination in motor windings, and thermal sensor malfunction under sustained cutting loads.

Common CHEVALIER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHEVALIER equipment arriving at our workshop.
- ✓Servo Amplifier Over-Current Shutdown (Alarm E36) — Mechanical jam in axis ballscrew, encoder cable discontinuity, or degraded servo motor windings cause spike current, triggering amplifier protection. Chevalier VMC and HBM series are prone to this when coolant ingress corrodes encoder connectors.
- ✓Spindle Encoder Loss (ERR-06 or ERR-09) — Vibration and thermal cycling in high-speed spindle operation fracture encoder cable insulation or loosen connector pins. Chevalier surface grinders and VMCs running extended finishing cuts experience this fault, halting spindle speed feedback.
- ✓Magnetic Chuck Power Supply Collapse — Prolonged magnetization duty and age degrade bulk capacitors in magnetic chuck DC supply modules fitted on Chevalier surface grinders. Workpiece slip and safety hazard result from gradual voltage droop from rated 1200V DC to <800V DC.
- ✓CNC Control Board Watchdog Timeout (RESET Loop) — Aging DRAM or flash memory corruption in Chevalier CNC modules causes cyclic micro-reset. Communication lag between motion processor and I/O module cascades into continuous watchdog resets — freezing the machine mid-cycle.
- ✓Tool Changer Pneumatic Valve Coil Burnout — Chevalier VMC tool changer solenoid coils suffer voltage transient damage during heavy tool change cycles or inadequate compressed air filtration, causing tool arm jam and loss of automatic tool selection.
- ✓Thermal Runaway in Spindle Motor Bearing — Loss of spindle preload or bearing race wear in Chevalier high-speed spindles (8000+ RPM) triggers friction-induced heat. Thermal sensor detects >120°C, causing automatic spindle shutdown and production halt on critical finishing operations.

Frequently Asked Questions — CHEVALIER Repairs
Do you repair Chevalier CNC machines anywhere in India?+
Yes. Synchronics repairs the full Chevalier product range — vertical machining centres, horizontal boring mills, surface grinders, spindle motors, servo drives, and CNC control systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Work completed in our Vadodara, Gujarat facility with 3-7 day turnaround for most servo and control faults.
What are the most common Chevalier machine electronic faults in Indian industry?+
Servo amplifier over-current shutdown, spindle encoder loss, magnetic chuck power supply degradation, and CNC control board watchdog resets account for ~70% of Chevalier repairs we perform. These occur due to vibration, thermal cycling, coolant contamination, and age-related capacitor failure. Synchronics has debugged thousands of Chevalier fault codes — we diagnose root cause within 24 hours of intake.
Can you repair Chevalier spindle VFD and motor assembly?+
Absolutely. Chevalier spindle motors and integrated VFD controllers are a core repair focus for Synchronics. We handle thermal runaway, encoder misalignment, bearing preload issues, MOSFET bridge failures, and phase loss scenarios. We test spindles to rated RPM on our dynamometer — ensuring safe, vibration-free operation at full production speed.
Do you have spare parts inventory for Chevalier machines?+
Synchronics maintains critical spare inventory including servo amplifier modules, encoder cables, solenoid coils, capacitor banks, and control board IC replacements for Chevalier VMC, HBM, and grinder series. For obsolete modules, we source OEM-compatible parts from authorised distributors or perform component-level rebuild. Lead time typically 2-5 days on in-stock items.
How do I know if my Chevalier machine needs electronics repair versus mechanical service?+
Electronic faults typically present as alarm codes (E36, ERR-06, RESET loop), loss of axis motion with servo humming, spindle not ramping to speed, or tool changer jam without mechanical obstruction. Mechanical issues show grinding noise, oil leakage, or visible wear. Synchronics offers free fault diagnosis — call our hotline, describe the symptom, and we advise if electronic repair, mechanical service, or both are needed. Most Indian shops benefit from combined electrical + mechanical servicing every 24-36 months.
How do I send my CHEVALIER 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 CHEVALIER 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 CHEVALIER 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 CHEVALIER 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.
