Tree VMC 1000 Spindle Repair
The Tree VMC-1000 is a CNC vertical machining center. It comes fitted with a grease lubricated and belt driven spindle capable of running up to 8,000 rpm.
This Tree VMC 1000 spindle was completely disassembled when it arrived at our shop for evaluation and quoting. The customer did not provide the original bearings, but they did send some new bearings and a seal. Unfortunately, some of the bearings were not appropriate for the spindle. The tooling taper, drive dogs, and inner bearing spacer all had significant damage. The rear of the drawbar shaft had also been sheared off.
The first step upon approval of our quote was to have our in-house grinding and machining department manufacture a new inner bearing spacer, and perform a grind, chrome plate, and finish grind of the tooling taper. We reassembled the spindle with all new bearings, drawbar shaft, bellevilles, drive dogs, o-rings, assembly c-clips, snap rings, and assembly screws.
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.
