Abstract
A cutting machine includes linear electrical actuation for controlling linear reciprocating movement of a spindle and cutting tool. The cutting machine is suited for gear shaping cutting operations and the like. Linear electrical actuation may be used to control position of a hydraulic valve within the spindle, which controls hydraulic actuation and linear movement of the spindle. Linear electrical actuation may also be used to pivot the spindle to relieve the cutting and/or during the cutting stroke for gear crowning operations. A rotary actuator is also disclosed as incorporated into the pivoting saddle of such a cutting machine.
