The quick-change tool spindle front box from Davenport Machine was developed in conjunction with Davenport customers to cut hours off of every setup requiring a tool spindle change. The quick-change box allows the steel outer housing to be aligned and installed once, and interchangeable bronze liners can then be swapped in less than a minute. Changing from a stationary spindle to a revolving spindle or to a broaching spindle can be done without disturbing the spindle alignment.

The tool spindle contains a permanently installed and aligned steel outer housing and comes complete with the two most common bushing liners (1.125" and 1.375"). The tool spindle has interchangeability with Davenport Machine OEM parts, and 1.656" ID liners are also available.
