Matsuura MC-600VF Spindle Repair
The Matsuura MC-600VF is a 3-axis CNC vertical machining center, equipped with a CAT40 tool taper and running at up to 8,000 rpm.
This spindle was received without the front cover, and the rear shaft nut was completely backed off. Breakdown of the spindle revealed that the interior was full of contamination and some parts had corrosion. Integrated drive keys were badly damaged and gripper fingers were heavily worn.
The drawbar nut (spring holder) was stuck and needed to be machined off. The drawbar shaft had been plated and chrome was chipping off causing the Bellevilles to stick. The rear bearing journal for tapered roller measured with high runout.
This Matsuura spindle rebuild required the following actions:
- Reconditioned damaged drive keys
- Grind, chrome plate, and finish grind to the drawbar shaft
- Kiss grind the rear roller journal
- Installed all new bearings, Bellevilles, grippers, o-rings & 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.
