FADAL ENGINEERING CO. Product Lines We Repair
Our engineers are trained on the full FADAL ENGINEERING CO. product range. Below are the major product families we service.
Fadal VMC Series (Vertical Machining Centers)
Fadal's signature vertical milling platforms range from VMC 15, VMC 20, to VMC 40, featuring high-speed spindles (up to 12,000 RPM), rigid castings, and precision ball screws. Common repair needs include spindle bearing degradation, servo motor encoder failures, and control interface malfunctions.
Fadal Spindle Motor Systems
Fadal spindles utilize brush and brushless AC motor designs with integral cooling and high thermal stability. Repair issues include motor winding insulation breakdown, bearing wear, thermal sensor faults, and spindle brake pad degradation affecting machine precision.
Fadal Servo Drive and Motion Control
Fadal machines employ proprietary servo amplifiers and axis controllers for X, Y, Z motion. These drives interface with feedback encoders on ballscrews and spindle shafts. Common faults include capacitor dry-out in power stages, encoder signal loss, and servo tuning drift under thermal stress.
Fadal CNC Control Electronics
Fadal machines use proprietary control boards, I/O modules, and communication interface cards. Repairs address blown relay contacts, corroded connectors, RAM/ROM memory faults, and communication bus failures between control and spindle/servo subsystems.
Fadal Encoder and Feedback Systems
Incremental and absolute encoders on Fadal spindles and ballscrews provide critical position and speed feedback. Failures stem from connector corrosion in shop-floor humidity, cable flexure damage, optical element fouling, and signal conditioning IC degradation.
Fadal Power Supply and Thermal Management
Fadal machines employ multi-rail power supplies (±12V, ±5V, 24V DC) and thermal switches for spindle and servo bay cooling. Typical repairs involve rectifier bridge failures, voltage regulator IC burnout, thermal sensor open circuits, and fan motor failures.

Common FADAL ENGINEERING CO. Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FADAL ENGINEERING CO. equipment arriving at our workshop.
- ✓Fadal spindle loses speed or stalls under load — Spindle motor bearing wear or lubrication breakdown causes internal friction and mechanical drag. Motor winding insulation faults or servo amplifier current limiting can also restrict spindle acceleration, especially in high-production environments where duty cycles are continuous.
- ✓Servo drive fault light illuminates; axis motion restricted — Fadal servo amplifiers are susceptible to thermally-induced capacitor dry-out (especially in Indian summer heat above 40°C), causing ripple voltage spikes that trigger over-voltage or over-current shutdown. Encoder signal loss or improper servo tuning gains also trips fault detection.
- ✓Encoder signal loss; position readout shows random values — Fadal encoder cables running through motor bay environments suffer oxidation on DB9 or circular connectors due to moisture and metal chip dust. Optical encoder LEDs may also dim from thermal cycling or dust accumulation on code disk windows, breaking signal integrity.
- ✓CNC control board does not initialize; display remains blank — Fadal control boards often fail due to blown relay contacts (arcing from inductive load spikes when solenoids de-energize), RAM corruption from power supply ripple, or corroded edge-card connectors preventing proper backplane communication in humid shop floors.
- ✓Spindle brake does not engage; machine coasts to stop — Fadal spindle brakes use electromagnetic actuation with friction pads that wear under continuous use. Brake solenoid coils can burn open, spring tension weakens, or lining friction coefficient degrades from heat and metal fines contamination, especially in high-speed finishing operations.
- ✓Rapid axis jog movement jerky or stutters; precision drops — Fadal ballscrew and servo systems degrade due to play increase from worn nuts, backlash hysteresis, or servo tuning drift as feedback device ages. Contamination in ballscrew races from chip generation also introduces micro-stick-slip friction that degrades surface finish quality.

Frequently Asked Questions — FADAL ENGINEERING CO. Repairs
Do you repair Fadal CNC machines anywhere in India?+
Yes. Synchronics repairs the full Fadal product range — spindle motors, servo drives, control boards, encoders, and power supplies. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major Indian cities. Equipment is transported to our repair facility in Vadodara, Gujarat, where it receives comprehensive diagnostics, repair, and load-testing before return.
How do I know if my Fadal spindle bearing is failing?+
Telltale signs include increased spindle runout visible on indicator gauges, audible grinding or squealing noise under no-load rotation, excessive heat near the spindle nose, and gradual loss of spindle speed even at full throttle setting. Synchronics uses precision spindle test rigs to measure bearing radial play, preload, and thermal signatures. We then advise bearing replacement or spindle rebuild based on wear measurements.
What is the typical repair turnaround for a Fadal servo drive?+
Routine servo amplifier repairs — capacitor replacement, connector cleaning, and gain re-tuning — typically take 5-7 working days at Synchronics. Complex failures requiring IC replacement or board rewinding may extend to 10-14 days. We provide daily status updates and fast-track expedited service options for critical production machines. Emergency same-city repair visits are available from Vadodara.
Do you stock original Fadal replacement parts?+
Synchronics maintains a curated inventory of Fadal spindle bearings, servo capacitors, encoder modules, and control board components sourced from authorized suppliers. For obsolete or discontinued Fadal parts, we source quality equivalents and validate them against original specifications. Custom component sourcing can be arranged within 5-10 days for unique assemblies.
Can Synchronics upgrade or recondition my aging Fadal VMC machine?+
Yes. Beyond repair, Synchronics offers reconditioning services including spindle re-boring, ballscrew replacement, servo amplifier modernization with improved thermal design, and control board firmware updates. We assess your Fadal machine's residual value, discuss upgrade ROI, and provide phased implementation plans to minimize downtime while boosting precision and production throughput for Indian manufacturing clients.
How do I send my FADAL ENGINEERING CO. unit for repair?+

What is the cost of repairing a FADAL ENGINEERING CO. 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 FADAL ENGINEERING CO. 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.
