INDEX-WERKE Product Lines We Repair
Our engineers are trained on the full INDEX-WERKE product range. Below are the major product families we service.
INDEX-WERKE ABC Automatic Lathes
Multi-spindle automatic lathes with synchronized spindle drives and NC-controlled tooling. Common faults include servo amplifier failures, spindle encoder communication loss, and hydraulic proportional valve controller faults affecting tool indexing precision.
INDEX-WERKE iC Multi-Axis CNC Turning Centres
High-speed CNC turning centres with integrated spindle drives and live-tool capability. Repair demands include axis servo faults, tool-changer relay failures, and spindle orientation encoder loss causing unscheduled downtime.
INDEX-WERKE Hydromat Multi-Station Indexing Systems
Modular indexing and drilling workstation systems with pneumatic/hydraulic actuation and proportional control. Typical failures: proportional spool valve controller PCB faults, index solenoid coil burnout, pressure switch failures disrupting work cycle sequencing.
INDEX-WERKE Electronic Control Modules (ECM)
Proprietary microcontroller-based control boards managing spindle coordination, tool indexing, pressure regulation, and part handling. Repair includes firmware restoration, relay replacement, capacitor bank refurbishment, and connector corrosion remediation.
INDEX-WERKE Spindle Servo Amplifiers
Three-phase amplifiers delivering coordinated power to multiple spindle motors with speed feedback control. Common faults: IGBT bridge failures, DC bus capacitor aging, encoder connector intermittency, thermal runaway in high-production cycles.
INDEX-WERKE Hydraulic Pressure & Proportional Valve Controllers
Closed-loop pressure regulation and proportional directional control electronics managing clamp force, tooling pressure, and spindle brake actuation. Failures: P-I feedback loop oscillation, proportional solenoid linearity loss, pressure transducer signal drift.

Common INDEX-WERKE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INDEX-WERKE equipment arriving at our workshop.
- ✓Spindle encoder communication error - INDEX CNC unable to synchronize spindle speeds — Absolute or incremental encoder connector corrosion, cable shielding degradation, or encoder signal processor PCB failure common in dusty automotive supplier environments. INDEX systems depend on real-time spindle feedback for multi-spindle synchronization.
- ✓Servo amplifier IGBT failure - axis drives intermittently cut out during production — Thermal cycling from continuous high-speed cutting, inadequate heatsink cooling in poorly ventilated machine enclosures, or inrush current stress when INDEX proportional valves engage. Common in 24/7 production schedules at Indian automotive Tier-1 plants.
- ✓Proportional spool valve controller oscillation - erratic tool clamp pressure and indexing delays — P-I feedback loop tuning drift, pressure transducer nonlinearity, or contaminated proportional solenoid coil affecting response. INDEX hydraulic systems are sensitive to oil contamination and require precise pressure loop tuning.
- ✓Tool indexing failure - INDEX ABC lathe refuses to index to next station position — Solenoid coil open-circuit or shorted winding due to repeated thermal stress, mechanical jam from swarf in indexing cam, or index limit switch connector intermittency. High production rates amplify indexing solenoid duty cycle.
- ✓CNC control board bootup failure - INDEX lathe powers on but display remains blank — Electrolytic capacitor bank failure in power supply, flash memory corruption from sudden shutdown, or relay chatter under high-frequency load. Older INDEX machines (1990s-2000s) suffer widespread capacitor aging.
- ✓Spindle brake solenoid unresponsive - spindle does not lock when program commands stop — Brake solenoid coil failure, proportional valve spool stiction from old hydraulic oil, or brake pressure relief valve stuck open. Critical for part holding and tool change safety on INDEX systems.

Frequently Asked Questions — INDEX-WERKE Repairs
Do you repair INDEX-WERKE equipment at your Vadodara facility?+
Yes, exclusively. Synchronics is one of India's few authorized repair centers for INDEX-WERKE CNC and electro-hydraulic systems. We maintain OEM technical documentation and spare parts inventory for ABC automatic lathes, iC turning centres, and Hydromat indexing systems. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, and 50+ other cities. Average repair turnaround is 5-7 working days.
My INDEX ABC lathe is showing E14 error code (encoder sync loss). What is the repair cost?+
E14 indicates the CNC cannot establish communication with the spindle encoder interface. Diagnosis is free at our Vadodara workshop. Typical repair involves encoder connector cleaning, signal cable shielding inspection, or PCB replacement. Cost ranges from Rs 8,000-25,000 depending on root cause. We provide a repair quotation within 24 hours of receiving the machine.
What warranty do you offer on INDEX-WERKE repairs?+
All Synchronics repairs carry a 12-month warranty covering parts and labour. For critical components (servo amplifiers, spindle controllers), we offer optional 24-month extended warranty at 30% of repair cost. We also provide 6 months of complimentary phone support for troubleshooting and parameter tuning post-repair.
How do I know if my INDEX proportional valve needs repair versus just oil flushing?+
Synchronics performs a quick bench test: we apply air pressure to the proportional solenoid coil and measure response time and spool position with a dial gauge. If response time exceeds 150ms or spool stiction exceeds 0.5 bar, the internal spool requires cleaning or replacement. Oil flushing alone costs Rs 3,500; full spool replacement costs Rs 12,000-18,000.
Can Synchronics upgrade my older INDEX machine control electronics to modern standards?+
Yes, within limits. We have successfully retrofitted 1990s-era INDEX machines with modern servo drives, updated proportional valve controllers, and new CNC interfaces. A typical upgrade costs Rs 3-5 lakhs and extends machine life by 10-15 years. We conduct a site survey first to assess compatibility, then provide a detailed upgrade proposal.
How do I send my INDEX-WERKE 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-WERKE 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-WERKE 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-WERKE 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.
