Common Symptoms of Machining Center Spindle CNC machine tool spindle problem.
Mechanical spindle tool interfaces are divided into: ISO20, ISO25, BT30, BT40, BT50,
==
Common symptoms of mechanical spindle:
1. Loss of taper hole accuracy (bearing damage? Taper hole impact?)
2. Abnormal noise (motor broken? Spindle broken?) Worse damage to bearings
3. If the pulling knife shakes (insufficient pulling force), repair the pulling rod, replace the butterfly or spring, and repair the pulling claw,
4. Pulling cylinder (no belt shaft, direct coupling shaft), unable to loosen the knife, replace the seal, plate and grind,
5. If the bearing gets stuck or damaged, it may cause the shaft core to burn out,
The maintenance measures for mechanical spindles include: bearings, pull rods, puller cylinders, grinding taper holes, replacing claws and other accessories
==
Common faults of spindle motor:
1. Machine tool alarm, overcurrent, overvoltage, coil damage. Replace the coil and bearings,
2. Encoder alarm, (amplitude of A/B items is too large, speed exceeds tolerance, encoder disconnection)
3. There is abnormal noise, but it can rotate. Consider replacing the bearing,
The maintenance measures for the spindle motor include: replacing bearings, replacing encoders, and replacing coils,
