Kellenburger 1000U Workhead Spindle Repair
The Kellenberger 1000U workhead is a CNC cylindrical grinder spindle. It comes equipped with a grease lubricated and belt driven spindle capable of running up to 1,800 rpm.
This spindle from a universal cylindrical grinder came to us as a complete workhead assembly. It has a bearing complement which includes two different bearing types. Several tapered roller bearings are used to distribute the weight of the workpiece because they are capable of handling large radial & axial forces. The workhead also incorporates several radial bearings which also serve to distribute the load while reducing the coefficient of friction for less rolling resistance.
We replaced all the bearings, seals, o-rings, and bolts.
Because we received the entire workhead, we were able to inspect the spindle drive motor but it did not require any service other than new drive belts.
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.
