DMG-MORI Equipment We Repair — By Category
DMG-MORI Product Lines We Repair
Our engineers are trained on the full DMG-MORI product range. Below are the major product families we service.
DURATURN Series
Compact CNC turning centers for high-volume production of shafts, bushings, and rotary components. Common repair issues include spindle encoder failures, servo position drift on turret indexing, and coolant ingress into control cabinets causing relay chatter.
DURACENTER Series
Multi-axis machining centers (3, 4, 5-axis) for complex automotive and aerospace components. Frequent faults involve tool changer servo malfunction, spindle drive current spikes, hydraulic pressure transducer failures, and master alarm codes on the FANUC controller.
CMX Series
Universal horizontal and vertical machining centers for die/mold shops and job work. Common repair needs include coolant-related PCB failures, servo motor winding shorts, spindle bearing temperature sensor malfunction, and parametric setup loss.
NLX Series
Advanced tilting-spindle turning centers for synchronous multi-shaft production. Repair challenges include cross-shaft synchronization lag, proximity switch misalignment causing alarm stops, and servo tuning degradation over time.
LASERTEC Series
Precision machine tools with integrated laser machining capability for medical device and electronics components. Repair focus includes laser power supply controller faults, spindle motor thermal runaway, and CNC axis servo hunting under light loads.

Common DMG-MORI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DMG-MORI equipment arriving at our workshop.
- ✓FANUC Servo Alarm A77 — Position Deviation Excess — DMG-MORI turret indexing servo or spindle servo loses synchronization due to accumulated backlash, encoder cable intermittency, or servo gain tuning drift after extended spindle ramp-down cycles.
- ✓Spindle Drive Over-current Shutdown — Coolant Ingress — Hydraulic coolant or emulsion mist migrates into the spindle drive amplifier cabinet through inadequate ventilation louvers or damaged bellows seals, creating low-resistance paths between power stages and causing nuisance current spikes.
- ✓Tool Changer Servo Stall — No Tool Magazine Rotation — DMG-MORI automatic tool changer servo motor windings short internally due to thermal stress, or the servo feedback potentiometer loses contact from vibration, preventing the magazine from indexing to the next tool position.
- ✓CNC Parameter Loss After Power Cycle — Lithium backup battery in the FANUC control board ages or loses charge; SRAM data (tool offsets, probe calibration, spindle tuning) corrupts if UPS is absent, leaving the machine in alarm state.
- ✓Hydraulic Proportional Valve Pressure Spikes — Jerky Clamp Motion — Spool stiction in DMG-MORI's proportional directional control valve develops over months of coolant contamination; pilot pressure tuning degradation causes overshoot and instability in workpiece clamping cycles.
- ✓Spindle Bearing Temperature Sensor Failure — No Thermal Alarm — PT100 or thermocouple sensor in the spindle bearing housing becomes loose from vibration or corrodes from coolant mist, stopping the FANUC thermal monitoring circuit and risking undetected spindle overheat.

Frequently Asked Questions — DMG-MORI Repairs
Do you repair DMG-MORI CNC machines at your Vadodara facility?+
Yes. Synchronics repairs all DMG-MORI control electronics, servo drives, spindle motor modules, and hydraulic proportional valve controllers. We offer PAN-India pickup and delivery — send your failed control board from Mumbai, Pune, Bangalore, Chennai, or Delhi, and we return it repaired within 5-10 working days. Our Vadodara facility has FANUC diagnostic tools and DMG-MORI wiring documentation for rapid fault isolation.
What is the typical turnaround time for DMG-MORI DURATURN spindle servo repair?+
If the servo motor has an open winding or burned coil, rewinding takes 3-4 days depending on motor size and wire gauge. If the servo amplifier fails (A77 alarm), we diagnose the IGBT stage in 1-2 days and replace or repair the power module. Total repair cycle: 5-7 working days. Emergency express service available for production-critical automotive suppliers — call our hotline for same-city next-day delivery in Pune, Ahmedabad, or Bangalore.
Does your facility have FANUC diagnostic software for DMG-MORI control troubleshooting?+
Yes. We hold current licenses for FANUC LADDER III, CNC parameter analysis, and servo tuning software. Our technicians can read live alarm logs from your DMG-MORI DURACENTER or CMX machine, simulate fault conditions on our test rig, and compare your control board waveforms against baseline data. This diagnostic depth ensures we fix root cause, not just symptoms.
Can Synchronics supply OEM replacement servo motors or proportional valve cartridges if needed?+
We keep stock of common DMG-MORI servo motors (300W to 5 kW) and proportional valve cartridges. For rare or obsolete parts, we source through DMG-MORI's Indian authorized distributors (typically 4-6 weeks lead time). We also offer remanufactured alternatives — tested to OEM torque/pressure specs — at 40-50% cost saving. Submit your machine model and part number for a quote.
How do I prevent coolant ingress into my DMG-MORI spindle drive cabinet?+
Best practice: (1) Install a secondary coolant barrier blanket or drip tray below the spindle head. (2) Ensure cabinet intake filters are cleaned every 500 hours of spindle runtime. (3) Check bellows seals on hydraulic feed lines quarterly. (4) Apply conformal coating to spindle drive PCBs (we offer this service). (5) Install a de-mist extractor if you run high-volume emulsion coolant. Synchronics can audit your machine's coolant management and recommend preventive upgrades.
How do I send my DMG-MORI 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 DMG-MORI 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 DMG-MORI 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 DMG-MORI 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.
