INDEX Product Lines We Repair
Our engineers are trained on the full INDEX product range. Below are the major product families we service.
INDEX GU Series
Compact fully-automatic CNC turning centers with up to 8 spindles for high-volume small-part production. Common issues include servo offset errors, spindle thermal drift, and tool changer solenoid failures affecting part accuracy and cycle time.
INDEX TS Series
Twin-spindle turn-mill centers combining opposing spindles for complex geometry parts. Frequent faults include cross-axis servo calibration loss, spindle bearing preload drift, and coordinated motion controller board failures.
INDEX G Series
Gang-tool automatic lathes with multiple independently driven tools. Common repair needs involve tool post stepper motor failures, gang slide synchronization errors, and spindle speed regulation board malfunctions.
INDEX Spindle Control Modules
Specialized INDEX spindle servo amplifiers and vector drive modules for precision speed and torque control. Typical failures include thermal runaway, encoder communication loss, and PWM stage power device breakdown.
INDEX NC Controller Boards
Proprietary INDEX numerical control and motion control PCB assemblies managing multi-axis coordination and real-time spindle synchronization. Repair challenges include EEPROM corruption, axis servo loop instability, and safety relay circuit failures.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common INDEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDEX equipment arriving at our workshop.
- ✓Spindle speed regulation drift beyond tolerance — INDEX spindle servo amplifier thermal compensation loop failure or encoder feedback signal degradation from spindle bearing runout. Common in high-rpm operations causing part diameter variation and tolerance stack-up in automotive precision work.
- ✓Tool changer solenoid valve sticking or non-response — INDEX tool changer directional control solenoids accumulate debris from coolant mist or suffer coil winding insulation breakdown. Particularly problematic in high-tool-count INDEX GU series with rapid tool changes every 5-10 seconds.
- ✓Servo motor encoder communication error or CRC checksum failure — INDEX multi-turn rotary encoders experience intermittent SSI or CANopen protocol errors from connector corrosion, cable capacitance loss, or encoder IC decoder circuit degradation in humid Indian manufacturing environments.
- ✓Cross-axis servo synchronization loss on TS Series twin-spindle machines — INDEX TS twin-spindle opposing-axis servo gains become mismatched due to amplifier component aging, brake solenoid coil resistance drift, or loss of calibration offset stored in NC-U controller EEPROM.
- ✓Gang tool post stepper motor lost position or skipped steps — INDEX G-series gang tool post stepper drivers experience winding shorts from coolant ingress, or step pulse signal distortion from INDEX spindle EMI coupling into unshielded tool post encoder cable harness.
- ✓NC controller board EEPROM corruption or bootloader checksum error — INDEX NC-U or NC-A boards suffer EEPROM corruption from power supply glitches, operator interrupt during parameter storage, or CMOS battery depletion losing real-time clock and offset tables.

Frequently Asked Questions — INDEX Repairs
Do you repair INDEX equipment anywhere in India?+
Yes. Synchronics repairs the complete INDEX automatic lathe and CNC turning center range — spindle drives, servo amplifiers, tool changer controls, NC controllers, and stepper driver boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and 100+ other cities. Central facility in Vadodara, Gujarat with INDEX test benches and genuine spare parts stock.
How quickly can Synchronics repair my failed INDEX spindle servo amplifier?+
Most INDEX spindle servo failures diagnose and repair within 3-5 working days. We prioritize INDEX servo work due to critical machine downtime impact on automotive suppliers. Emergency same-day courier available from major metros. Turnaround includes full load-test on INDEX spindle simulator before shipment.
Do you stock original INDEX spare parts for repair or offer compatible alternatives?+
Synchronics maintains inventory of critical INDEX servo components, filter capacitors, relay modules, and connector sets. For obsolete parts, we source genuine INDEX replacements through authorized German distributors. We do not use non-INDEX substitutes on safety-critical components like spindle servo stages or NC controller boards — original specifications are non-negotiable for precision tolerances your customers expect.
Can you repair INDEX TS Series twin-spindle servo synchronization issues without full machine recalibration at the shop?+
Synchronics performs 90% of TS Series servo diagnosis and repair in our facility using dual-spindle INDEX test bench replica. We recalibrate spindle offset, servo loop gains, and brake solenoid timing to INDEX factory specifications. At machine site, only final runout verification and tool offset adjustment required — typically 2-3 hours installation by your INDEX-trained operator.
What documentation do you provide after repairing INDEX automatic lathe control systems?+
Synchronics provides full repair reports detailing fault diagnosis, component replacements, servo loop tuning parameters, and INDEX firmware versions programmed. Calibration certificates included for spindle speed stability and servo synchronization. We also supply detailed wiring diagrams, connector pin-outs, and parameter files in formats compatible with INDEX online service portals for your maintenance team reference.
How do I send my INDEX 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 INDEX 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 INDEX 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 INDEX 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.
