Repair History
Daewoo DMV500 Spindle Upgrade
10,000 RPM
This customer was rebuilding their Daewoo DMV 500 machine. The spindle was worn and they wanted to incorporate high pressure through the tool coolant into the design. We evaluated the spindle and incorporated the high pressure through tool coolant capacity into the drawbar mechanism. We added contamination prevention items to the spindle as the high pressure coolant usage increases the probability of coolant reaching the bearings.
Daewoo Minx 500
8,000 rpm
40 Taper
Spindle had 25 microns of run out in the taper and was contaminated with coolant causing the bearings to fail. Our evaluation determined that coolant was entering the spindle through the front labyrinth. We ground plate ground the taper and manufactured new labyrinth interfaces to improve contamination resistance. We then replaced the bearings, rebuilt the spindle, test ran it at speed, balance and final QC before shipment.
Doosan Puma MC Spindle Repair
This customer called saying that their 2 year old spindle is making chatter on the part. They said it sounds ok running with no load but makes noise during a cut. They sent the Doosan Puma spindle to us to be evaluated. We determined that the front bearings were worn. We proceeded with our standard
Daewoo spindle repair after we received approval from the customer. This spindle was shipped back to the customer with our standard warranty.
Doosan Ace-HP4000 BIG PLUS Spindle rebuild
8,000 rpm
40 Taper
Spindle had 25 microns of run out in the taper and was contaminated with coolant causing the bearings to fail. Our evaluation determined that coolant was entering the spindle through the front labyrinth. We ground plate ground the taper and manufactured new labyrinth interfaces to improve contamination resistance. We then replaced the bearings, rebuilt the spindle, test ran it at speed, balance and final QC before shipment.
Doosan Mynex 540
50 Taper
The bearings of this spindle were loud during operation. They had reached the end of their life. The taper had 12 microns of run out. We were able to kiss grind the taper to eliminate the run out. The rebuild was completed and the spindle was balanced, test run and put through our quality check.
