CNC ELECTRONICS Product Lines We Repair
Our engineers are trained on the full CNC ELECTRONICS product range. Below are the major product families we service.
Spindle Drive Controllers
Variable frequency and DC spindle motor drives for CNC machine tool spindles. Common faults include capacitor degradation, thyristor failures, and speed feedback circuit breakdown affecting spindle RPM stability.
Servo Amplifier Modules
Closed-loop servo motor amplifiers and axis positioning controllers. Common failures: encoder interface faults, position drift errors, overheating thermal shutdowns, and hall sensor signal loss during rapid acceleration cycles.
CNC Control Panels and Enclosures
Integrated electrical control cabinets with emergency stop relays, contactor circuits, and safety interlocks. Repair issues include relay chatter, contactor coil burnout, and PLC input module degradation under dusty shop-floor conditions.
PLC and Motion Control Boards
Programmable logic controllers and real-time motion timing boards for axis synchronisation. Typical faults: memory corruption, brownout resets, analogue input drift, and firmware version incompatibility during machine upgrades.
Encoder and Feedback Interface Cards
Signal conditioning cards for rotary and linear encoders, proximity sensors, and position transducers. Common issues: shielding degradation in high-EMI environments, differential line termination faults, and quadrature signal phase misalignment.
Coolant and Auxiliary Control Electronics
Pump motor starters, temperature sensors, and level switches for machining fluid systems. Repair needs: thermal overload relay replacement, pump contactor restocking, and sensor cable shielding restoration.

Common CNC ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CNC ELECTRONICS equipment arriving at our workshop.
- ✓Spindle speed fluctuation and hunt oscillation — CNC ELECTRONICS spindle drive feedback amplifier circuits suffer from degraded capacitors or loose speed feedback potentiometer connections, causing closed-loop control instability. Humidity ingress in the spindle connector housing also corrodes the encoder signal wiring.
- ✓Servo axis position error and runaway movement — CNC ELECTRONICS servo amplifier modules lose quadrature encoder signals due to connector pin corrosion or internal comparator IC failure. Hall sensor signal dropout during rapid axis movement also triggers servo runaway and emergency stop trips.
- ✓CNC control panel contactor chatter and electrical chattering — CNC ELECTRONICS contactor coil voltage supply becomes marginal due to transformer tap degradation or loose terminal lugs, causing intermittent magnetic holding. Repeated coil energise-de-energise cycles overheat the contact springs.
- ✓PLC memory corruption and watchdog timer resets — CNC ELECTRONICS PLC boards experience power supply ripple and noise during rapid spindle and servo current transients. Electrolytic capacitors on the PLC 24VDC supply lose capacitance with age, allowing brownout conditions that trigger firmware watchdog resets.
- ✓Encoder signal loss and axis homing failure — CNC ELECTRONICS encoder interface cards in the control cabinet suffer from differential line termination resistor drift or removal of shielding during earlier maintenance work. Factory shop-floor EMI from welding machines and motor starters induces noise into unshielded encoder cables.
- ✓Coolant pump motor start failure and soft-start timeout — CNC ELECTRONICS pump control boards develop open circuits in the motor contactor coil drive stage or thermal overload relay settings drift due to age. Pump inlet blockages cause high starting inrush current that nuisance-trips the soft-starter current limit circuit.

Frequently Asked Questions — CNC ELECTRONICS Repairs
Do you repair CNC ELECTRONICS equipment anywhere in India?+
Yes. Synchronics repairs the complete CNC ELECTRONICS product range — spindle drives, servo amplifiers, PLC control boards, and auxiliary electronics. We offer PAN India courier pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all industrial towns. The main repair facility is in Vadodara, Gujarat. Standard turnaround is 5-7 working days for most repairs.
What is the typical cost and time for CNC ELECTRONICS spindle drive repair?+
CNC ELECTRONICS spindle drive controller repairs typically cost Rs 8,000-25,000 depending on the fault severity. Capacitor replacement and re-calibration takes 3-4 days. If servo output stage power transistors or the main control transformer require replacement, costs and time may increase. Synchronics provides a detailed quotation after initial fault diagnosis, with no diagnostic charges.
Can Synchronics repair CNC ELECTRONICS boards with burnt or corroded traces and components?+
Yes. Synchronics has in-house PCB rework capability — we perform micro-soldering, replace surface-mount and through-hole components, repair cracked traces with wire bridging, and restore conformal coating. For heavily damaged CNC ELECTRONICS control boards, we can rebuild entire sub-circuits or source factory replacement modules if economical. All rework is tested under operating load.
Do you provide spare parts and replacement modules for CNC ELECTRONICS equipment?+
Synchronics stocks common replacement modules for CNC ELECTRONICS spindle drives, servo amplifiers, and relay logic boards. We maintain relationships with authorised distributors in India to source OEM parts. For older or obsolete CNC ELECTRONICS models, we offer functional equivalent modules from compatible manufacturers or perform board-level repairs as a cost-effective alternative.
What after-sales support and warranty do you offer on CNC ELECTRONICS repairs?+
All CNC ELECTRONICS repairs carry a standard 12-month functional warranty covering the repaired sub-assembly. Synchronics provides free technical support during the warranty period. We supply detailed fault analysis reports, component replacement lists, and re-commissioning checklists. Customers receive a physical repair tag on every unit and electronic records for maintenance planning.
How do I send my CNC ELECTRONICS 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 CNC ELECTRONICS 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 CNC ELECTRONICS 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 CNC ELECTRONICS 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.
