Abstract:
1. A secondary power tool system for use with an automatic tool change CNC machine having a tool receiving element mounted in a housing, and an available pneumatic source of compressed gas, the power tool system comprising: a pneumatic delivery interface component linkable to the available pneumatic source and mountable to the machine housing adjacent to the machine tool receiving element, the interface comprising an interlock to modulate and selectively obstruct compressed gas flow there through; and a high-speed rotating spindle accessory component comprising a housing, a pneumatic motor operatively disposed in the housing, a delivery probe for receiving compressed gas from the delivery interface; delivery means for delivering compressed gas from the delivery probe to the motor, and a spindle assembly linked to the motor wherein a portion of the housing is receivable by the machine tool receiving element and the probe couples with the pneumatic delivery interface component to operate the interlock, thereby causing the interlock to permit passage of compressed gas when the accessory is received by the machine tool receiving element.
