This spindle had the retention knob break during cutting causing galling of the taper. This customer called us to have an in-house taper grind done. Unfortunately there was not enough clearance in the Brother machine to accommodate our taper grinder. We sent our technician to the plant to access the options. While he was there it was decided to have him remove the spindle and bring it to Northland Tool. We were able to kiss grind the taper in assembly on one of our Kellenburger grinders saving the customer the cost of a spindle rebuild.
