Power Draw Bar Spindle

Accu-Router, Inc. announced the introduction of the new XR-15 power draw bar spindle with a 63F HSK tooling interface. This is the first such spindle manufactured in the U.S. in production. HSK precision tooling has become the standard in aerospace and other high tolerance industries for machine tools with automatic tool changers. The new XR-15 spindle at Accu-Router will encompass several industry leading features designed to support higher cutting rates, longer tool holder and cutting tool life, and longer spindle life.

HSK is a German tooling interface designed to grip on the inside of a “hollow shank” precision tool holder instead of the outside of a tapered tool holder. Centrifugal force thus helps to assure that tool holders will not slip or turn as cutting rates or spindle speeds increase. This new spindle will enter production at Accu-Router in the second quarter of 2004. The rated speed range will be 3,600 to 24,000 rpm. The higher speeds will support much higher cutting rates in most materials.

As with all Accu-Router premium spindles, this HSK spindle is liquid chilled, uses spray mist for bearing lubrication, has a cast iron outer housing, includes several sen-sors to help users avoid early failure and is supported by Accu-Router directly, including with back-up loaner spindles when service is required.
