Abstract
A crankshaft milling apparatus is provided including a bed having a front and rear side. The bed includes a slanted portion on the rear side of the bed. A milling unit is pivotally mounted on the rear slanted portion of the bed with the milling unit carrying the internal milling cutter for encircling a crankshaft extending along the front side of the bed. The front side of the bed is open such that the milling cutter is easily accessible without having to climb into the machine.
Claims18
A crankshaft milling apparatus comprising:
- a bed having an open front side;
- a slanted portion on the bed on a rear side of the bed;
- crankshaft holding devices mounted on the bed for holding a crankshaft at the open front side of the bed;
- a pivotable milling unit mounted on the rear slanted portion of the bed;
- a milling cutter carried by the milling unit and projected over the open front side and encircling a crankshaft to mill the same, the milling cutter being accessible from the open front side of the bed;
- and
- a plate-shaped cutter head member of the milling unit for carrying the milling cutter in a front end portion thereof with the plate-shaped cutter head member extending transversely to the crankshaft and extending from the rear of the bed to the open front side of the bed generally inclined along the slant of the rear side slanted portion of the bed so that only the front end portion of the cutter head member is disposed over the open front side of the bed.
