Fadal CNC machines are well regarded in many workshops because they combine precision, durability, and reliable everyday performance. Like any finely engineered tool, however, the drive motors eventually accumulate wear and tear, leading to behaviour outside the factory norm. Detecting early clues can spare a facility costly downtime and help production run according to plan. The following sections describe the tell-tale signs that indicate a Fadal CNC motor requires attention, ranging from a minor fix to full replacement. Unusual Noises Coming from the Motor Grinding, squealing, or an unexpected hum are among the first red flags engineers notice. These abnormal sounds can stem from several common issues: Worn bearings if grease has dried out or debris has contaminated the raceways. Misalignment when shafts, couplings, or mounting pads are out of specification. Electrical troubles; a weakening stator or uneven windings can produce a piercing rattle. Letting the motor run with these noi...
