Common EDM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EDM equipment arriving at our workshop.
- ✓Servo axis instability and lost axis positioning accuracy — EDM servo encoders accumulate magnetic interference from high-frequency pulse generators, or servo amplifier gain parameters drift due to thermal aging. X, Y, Z position feedback becomes unreliable, causing electrode-to-workpiece distance loss.
- ✓Wire break detection failure and uncontrolled electrode advance — Wire tension sensor or wire break relay contact deteriorates from spark erosion or mechanical fatigue. EDM power supply fails to detect open circuit condition, allowing electrode to crash into workpiece at rapid feed rate.
- ✓Power supply frequency drift and poor surface finish quality — EDM pulse generator frequency reference oscillator drifts due to capacitor aging or transformer secondary tap connection looseness. Discharge frequency falls below optimal cutting frequency, resulting in excessive recast layer and micro-cracks on machined surface.
- ✓Gap voltage sensor signal loss and automatic retract failure — Gap voltage sensor connectors oxidize or connector pins bend due to vibration in the machine enclosure. EDM control loses gap feedback, triggering false electrode retract commands or allowing voltage runaway during high-current pulses.
- ✓Flushing pressure control solenoid coil failure and debris accumulation — Dielectric fluid contamination or high-voltage transients induce solenoid coil shorts. Loss of flushing pressure allows spark debris (electrode and workpiece particles) to accumulate in the gap, causing wire breakage and machining defects.
- ✓Safety relay contact welding and emergency stop unresponsiveness — High inrush current during EDM pulse generation causes electrical stress on safety relay contacts. Contact material welds under arcing conditions, preventing relay from opening circuit when emergency stop is pressed or machine fault detected.

Frequently Asked Questions — EDM Repairs
Do you repair EDM equipment anywhere in India?+
Yes. Synchronics repairs the complete EDM electrical control spectrum — power supplies, servo drives, safety relays, gap sensors, wire feed systems, and flushing controls. We offer door pickup and delivery across India from our Vadodara, Gujarat facility. Same-day turnaround available for urgent power supply and servo drive repairs affecting automotive and aerospace precision shops.
Can you repair my EDM machine's servo drive and encoder system if it's not an original EDM component?+
Absolutely. Many Indian precision shops retrofit EDM machines with Fanuc, Siemens, or Yaskawa servo drives to improve performance. Synchronics repairs and recalibrates these third-party servo systems as integrated components within the EDM control architecture. We have cross-brand expertise ensuring servo tuning parameters match EDM power supply dynamics and wire feed specifications.
What is causing my EDM wire cutter to produce a heavy recast layer and micro-cracks on finished surfaces?+
Recast layer buildup typically indicates pulse frequency drift below optimal EDM cutting frequency (usually 200-500 kHz depending on wire gauge and material). This causes larger sparks with higher energy density, increasing thermal stress on the machined surface. Synchronics measures your pulse generator frequency against calibration standards and adjusts oscillator tuning to restore surface finish quality. We also verify gap voltage stability and flushing pressure regulation — both critical to controlling spark energy.
How often should EDM power supplies be serviced to avoid downtime in our manufacturing plant?+
Synchronics recommends annual preventive maintenance on EDM power supplies operating in Indian manufacturing environments — higher humidity and dust contamination accelerate capacitor aging and component oxidation compared to European conditions. We perform frequency calibration, dielectric strength testing, and thermal imaging to identify aging components before failure. Most automotive suppliers and Tier-1 shops schedule this during planned production shutdowns to minimize impact.
Your website mentions EDM repair — does this include wire tension feedback systems and wire break detection circuits?+
Yes, wire tension and break detection are core EDM electrical systems we repair. We test and calibrate wire tension sensors, replace worn relay contacts in break detection circuits, and verify signal integrity across the wire feed servo loop. Many wire EDM faults originate in these circuits — failed sensors cause uncontrolled electrode advance and costly workpiece damage. Synchronics has dedicated test equipment for wire EDM-specific diagnostics.
How do I send my EDM 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 EDM 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 EDM 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 EDM 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.
