With a wealth of precision mechanical engineering experience, Kugel Motion is able to offer simple precision spindle refurbishments and repairs. They perform run-in tests whilst monitoring bearing temperatures while the spindle bearings 'bed-in' following replacement.
The image below shows a large spindle head from a Dorries Scharmann DST BK2 Horizontal Mill (approx. 1000kg), which was completely overhauled with extensive replacement part manufacturing with new bearings and seals fitted throughout. This head had drive positioning errors caused by a heavily worn and damaged drive coupling which was re-manufactured.
Other images are from a Pietro Carnarghi Universal Head which had a catastrophic failure during operation. The spindles were fully stripped, new precision components were machined and replaced, new seals and bearings were fitted throughout & the draw bar was fully refurbished. Images show the universal head fully stripped, being reassembled, and tested using thermal imagery.
