PRODUCTION BROACHING
A Driven Broaching Unit can dramatically decrease the cycle time involved with keyway slotting or spline broaching. The broach head converts the rotary motion of the turret into linear motion allowing for faster speeds and quicker implementation of the slotting tool. Here is an article in Production Machining magazine describing a clients experience slotting their 4140 motor shafts with CNC Broach Tools on the driven broaching unit. The 4140 was at 56 Rc!
