Description: |
| Abstract:
An improved portable milling machine adapted to grip a work piece and to cut a keyway through a clamping area. This is accomplished without releasing the grip of the milling machine on the work piece by forming an elongated slot in a bed plate with lands lying at opposite sides of the elongated slot. A clamp plate is arranged in stacked alignment with said lands and a work piece is gripped between the clamp plate and the lands of the bed plate. This structure permits a cutting element to pass through the elongated slot to cut a keyway upon the work piece while said work piece is gripped, the cutting action being performed through the clamped area. Improvements include interchangeable spindle construction allowing the use of a variety of cutter elements. |
