CHARMILLES TECHNOLOGIES Product Lines We Repair
Our engineers are trained on the full CHARMILLES TECHNOLOGIES product range. Below are the major product families we service.
Robofil Series (Wire EDM Controllers)
CNC-controlled wire EDM systems with advanced motion control and servo feedback. Common issues include servo axis drift, encoder signal loss, discharge stabilisation faults, and coolant pump controller failures affecting cut quality and tolerance maintenance.
Roboform Series (Sinker EDM Controllers)
Precision sink EDM machines with complex servo positioning and power pulse control. Typical faults: servo tuning instability, power stage regulation loss, servo amplifier thermal trips, and gap voltage sensor malfunction causing sparking irregularities.
LaserSpark Series (Laser Cutting Controllers)
CO2 and fibre laser cutting CNC systems with XY scanning servo control and pulse logic. Repair scope: laser tube driver failures, XY servo amplifier faults, galvanometer mirror servo errors, and coolant circulation sensor issues.
Servo Amplifier Modules (Universal)
Standalone servo drive cards for axis control across all Charmilles platforms. Prone to capacitor ageing, MOSFET breakdown under load transients, encoder interface faults, and brownout recovery errors in Indian grid conditions.
CNC Logic Boards (Processor Modules)
Embedded control processors handling axis interpolation, tool path execution, and M/G-code logic. Common defects: firmware corruption, RAM parity errors, serial port failures, watchdog timer resets, and input/output card connectivity loss.
Power Supply Units (PSU Cabinets)
Multi-output regulated supplies for servo, logic, and spindle circuits. Failure modes: transformer winding degradation, rectifier bridge aging, capacitor ripple breakdown, thermal protection nuisance trips, and 3-phase imbalance sensitivity.

Common CHARMILLES TECHNOLOGIES Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHARMILLES TECHNOLOGIES equipment arriving at our workshop.
- ✓Servo axis exhibits creep or drift during idle hold — Encoder signal degradation due to cable shielding loss or optical encoder window contamination. Charmilles servo loops are sensitive to 16-bit encoder resolution — even minor signal noise causes axis slip in precision positioning mode.
- ✓Wire EDM discharge stops intermittently or sparks become erratic — Power stage pulse circuit failure in the sinker/wire controller or gap voltage feedback sensor malfunction. Charmilles systems require stable 5V reference for servo positioning — any ripple disrupts discharge timing and feed rate control.
- ✓Servo amplifier thermal shutdown during light cutting load — MOSFET thermal path degradation, dried-out thermal compound, or PWM switching losses. Indian ambient temperatures (40-50°C) accelerate capacitor ageing in Charmilles power stages, reducing cooling efficiency and triggering overheat protection prematurely.
- ✓CNC controller loses home position reference after power dip — Watchdog timer logic or dual-axis homing sequence error following brownout recovery. Charmilles embedded controllers cache home offsets in volatile RAM — 50ms power loss corrupts position registers across servo circuits.
- ✓Spindle motor fails to reach target speed or oscillates — Spindle servo amplifier phase loss, hall sensor alignment error, or commutation sensor noise. Charmilles spindle drives use sensorless back-EMF feedback — any encoder misalignment or hall-effect sensor offset causes speed regulation loop instability.
- ✓Machine responds slowly to G-code commands or exhibits axis jitter — Serial communication protocol error between CNC main processor and servo amplifier cards. Charmilles systems use proprietary real-time servo-link protocol — corrupted data frames, baud rate mismatch, or cable capacitance cause command latency and servo loop instability.

Frequently Asked Questions — CHARMILLES TECHNOLOGIES Repairs
Do you repair Charmilles Technologies equipment anywhere in India?+
Yes. Synchronics is authorised for Charmilles servo drives, CNC controllers, spindle motors, and power electronics across India. We collect equipment from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all metros. Complete repair and testing happens in our Vadodara, Gujarat facility. Turnaround is typically 5-7 days for servo and logic board repairs.
What is the typical repair cost for a Charmilles servo amplifier fault?+
Servo amplifier repair costs INR 8,000–25,000 depending on fault severity. Capacitor/diode failures are INR 8,000–12,000. MOSFET or integrated circuit replacement runs INR 15,000–22,000. Complete servo card rebuild with thermal management upgrades is INR 20,000–28,000. Synchronics provides warranty and diagnostics report at no charge before repair approval.
How do I know if my Charmilles wire EDM controller power stage is failing?+
Signs include erratic discharge spark, feed rate instability, servo axis creep during cutting, or intermittent error codes on the display. Synchronics diagnoses via pulse waveform analysis and gap voltage sensor testing. If spark frequency drops below 200 kHz or discharge current fluctuates >10%, the power stage needs replacement or capacitor service. Contact us with machine model and symptom photos for free preliminary assessment.
Can Synchronics repair Charmilles CNC logic boards and reprogramme firmware?+
Yes. We repair Charmilles CPU modules, I/O cards, and memory modules. Repair includes component-level diagnosis, solder joint reflow, IC replacement, and hardware validation. For firmware issues, we work with your original Charmilles controller documentation or consult archived manuals. EPROM and EEPROM re-programming is done in-house with verified checksums. Most logic board recoveries preserve your original part programs and machine settings.
What warranty do you offer on Charmilles repair?+
Synchronics provides 12 months parts warranty and 6 months labour warranty on all Charmilles repairs. If a repaired component fails within warranty due to defective workmanship, we repair or replace it free of charge. Travel and diagnostic charges are waived for in-warranty claims. We also offer extended 24-month warranty on critical servo drives and CNC controllers for an additional service fee.
How do I send my CHARMILLES TECHNOLOGIES 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 CHARMILLES TECHNOLOGIES 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 CHARMILLES TECHNOLOGIES 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 CHARMILLES TECHNOLOGIES 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.
