GRAVOTECH Equipment We Repair — By Category
GRAVOTECH Product Lines We Repair
Our engineers are trained on the full GRAVOTECH product range. Below are the major product families we service.
Gravotech CO2 Laser Systems
CO2 laser tubes rated 40-150W for industrial marking and engraving. Common failures include tube burnout due to coolant degradation, high-voltage power supply failures, and resonator alignment issues causing beam instability.
Galvanometer Scanning Systems
Precision galvo mirrors and servo drivers enabling 2D/3D laser vector marking. Failures manifest as beam positioning errors, lost sync between XY axes, and thermal drift in galvo coils affecting mark precision.
Gravotech Control Electronics
Industrial PLC, motion controllers, and HMI touchscreens managing laser parameters and job queuing. Faults include SD card corruption, relay chattering causing intermittent laser firing, and Ethernet communication timeouts.
RF Power Supply Units
Radio-frequency power generation for CO2 and RF-excited laser tubes. Common failures: high-voltage arcing, capacitor failure under thermal stress, and frequency drift causing tube inefficiency and heat buildup.
Optical & Cooling Subsystems
Laser mirrors, lenses, beam combiners, and chiller units maintaining tube temperature and optical alignment. Degradation includes mirror coating peeling, chiller compressor failure, and coolant contamination reducing beam quality.

Common GRAVOTECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAVOTECH equipment arriving at our workshop.
- ✓CO2 laser tube complete burnout or low output — Gravotech CO2 tubes degrade from inadequate coolant circulation, mineral buildup in cooling channels, or excessive duty cycles without thermal management. Coolant contamination accelerates tube electrode erosion and tungsten cathode degradation.
- ✓Galvanometer XY scanning axis out of sync or beam drift — Gravotech galvo drivers experience thermal drift when ambient temperature fluctuates, or servo feedback potentiometers fail under vibration and continuous operation. Mirror mechanical play develops from bearing wear in precision scanning heads.
- ✓RF power supply no output or erratic tube firing — Gravotech RF supplies fail due to high-voltage transformer saturation, electrolytic capacitor drying under continuous 50-60Hz AC stress in Indian climates, and tube arc-back damaging output circuits. Frequency drift prevents resonance matching with laser tube.
- ✓Control board Ethernet loss or job queue freezing — Gravotech control boards suffer SD card filesystem corruption from unexpected power loss during file write operations, network switch port failures, and overheating of Ethernet PHY chips near RF power stage. Software watchdog timer crashes cause application hang.
- ✓Water chiller unit compressor failure or coolant leakage — Gravotech chiller systems fail from refrigerant undercharge due to line leaks, compressor bearing wear from vibration and mineral-contaminated coolant, and thermostat sensor malfunction causing ice-up or overheat cycles.
- ✓Beam misalignment or distorted engraving pattern quality — Gravotech optical path degradation occurs from mirror coating wear and oxidation, lens contamination from dust and vaporized tube electrodes, and mechanical vibration from mounting looseness. Beam delivery optics shift from thermal expansion in aluminum housings.

Frequently Asked Questions — GRAVOTECH Repairs
Do you repair Gravotech laser systems across India?+
Yes. Synchronics Electronics repairs the full Gravotech product range including CO2 laser tubes, galvanometer scanners, RF power supplies, control boards, and chiller units. We offer PAN-India pickup from Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Pune, and all major industrial hubs. Our Vadodara facility provides fast turnaround — most Gravotech repairs completed within 5-7 business days.
My Gravotech laser tube output has dropped to 60% after 2 years. Is the tube dead?+
Not necessarily. Gravotech CO2 tubes gradually lose power due to coolant contamination and mirror coating oxidation long before catastrophic failure. Synchronics performs full optical alignment check, coolant analysis, and tube gas pressure testing. We often restore output to 85-90% through mirror cleaning, chiller servicing, and realignment — saving you the cost of new tube replacement.
What is the typical cost and lead time for Gravotech laser tube replacement?+
Gravotech CO2 replacement tubes (40-150W) cost INR 35,000-85,000 depending on wattage and tube length. Synchronics sources OEM Gravotech tubes or equivalent Coherent/Hyper tubes, fitted and pressure-tested in 2-3 days. We include resonator realignment and laser power meter verification. Emergency overnight parts sourcing available for critical production lines.
How do I know if my Gravotech galvanometer scanner needs replacement or just recalibration?+
Gravotech galvo failures show as beam positioning lag, XY axis asymmetry, or thermal drift over the job runtime. Synchronics diagnoses via software calibration test mode and mechanical bearing play inspection. 70% of cases are software recalibration and thermal compensation tuning — no hardware replacement needed. Full mechanical replacement is recommended only if servo feedback resistance is out of spec or mirrors show backlash over 0.3mm.
Can Synchronics help optimize my Gravotech laser system for higher throughput and better mark quality?+
Absolutely. Beyond repair, Synchronics offers preventive maintenance packages for Gravotech users: monthly coolant condition monitoring, quarterly optical alignment tuning, and annual power supply stress testing. We also provide firmware updates, galvo calibration optimization, and parameter tuning to improve engraving speed by 10-20% while maintaining precision. Contact our service manager to schedule a site visit.
How do I send my GRAVOTECH 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 GRAVOTECH 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 GRAVOTECH 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 GRAVOTECH 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.
