Spindle Rebuilding and Retrofitting Process
  • Dimensions are taken from the old spindle bar. A complete set of drawings or blueprints are made from this information.
  • The insert is manufactured (with a spare) and a third insert is machined to a rough state.
  • All machining equipment is loaded into a truck, brought on-site and positioned in-place for retrofit.
  • All machining operations are completed on the spindle bar, in-place.
  • The insert is installed into the bar and an inspection is performed.
  • Test cuts are made with the machine to complete the inspection.
  • An extra insert is left with the customer, to be used as a spare.
