Daewoo DMV4020 Spindle Repair
The Daewoo DMV4020 is a CNC vertical machining center. This machine comes equipped with a belt driven and grease lubricated spindle capable of running up to 8,000 rpm.
Our customer indicated that this vertical turning center spindle had been crashed, and that the tool holder retention knob had snapped. The tool holder had spun, causing significant damage inside the shaft tooling taper.
Our initial inspection showed that the top of the broken retention knob was still left up in the taper. Not only did the broken tool tear up the taper, but it had also caused severe damage to the gripper (collet) fingers. We noticed additional damage to the face of the spindle shaft, especially near the drive dog (key) slots. The races of the #1 front bearing were also brinelled from the impact of the crash. Finally, our dimensional inspection showed that the front bearing journal of the shaft was egged (out of round) with excessive runout where the #1 bearing locates.
The following actions were performed on this Daewoo DMV4020 spindle:
- Clean all parts of the spindle
- Replace all bolts, o-rings, and bellevilles
- Replace gripper fingers
- Replace bearings
- Grind, chrome plate & finish grind the tooling taper and the front bearing journal of the spindle shaft
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
