Claims
- 1. A crankshaft milling machine comprising milling slide means, drive spindle means rotatably supported in said milling slide means, exchangeable milling tool means including an arbor and a plurality of disk milling cutters operatively held on said arbor, means for maintaining said disk milling cutters at axial spacings from one another along said arbor of said exchangeable milling tool means, bearing means rotatably supporting said arbor of said exchangeable milling tool means at least at two axially spaced locations in said milling slide means, said bearing means comprising only one axial bearing located between two adjacent disk milling cutters of said plurality of disk milling cutters, mounting means for mounting the milling tool means exchangeably on the milling slide means independently of the drive spindle means and along a common axis of rotation, and clutch means operatively interposed between said drive spindle means and said exchangeable milling tool means, said clutch means comprising cooperating surface means including clutch surface means and complementary surface means formed in the drive spindle means and in said milling tool means, said cooperating surface means being oriented generally parallel to the common axis of rotation, said clutch means further comprising means for engaging said cooperating surface means thereby transmitting torque but not axial forces, said mounting means together with said clutch means permitting the removal of said exchangeable milling tool means as a unit including said arbor and disk milling cutters.
- 2. The machine of claim 1, wherein one of said disk milling cutters is located for milling a crankshaft thrust bearing and wherein the bearing means located closest to said one disk milling cutter comprises an axial bearing.
- 3. The machine of claim 2, wherein said milling tool means comprise a longitudinal axis having two ends, and an axial center on said longitudinal axis intermediate said ends, and wherein the bearing means located closest to said axial center comprises an axial bearing.
- 4. The machine of claim 1, wherein said milling tool means comprise a longitudinal axis having two ends, and an axial center on said longitudinal axis intermediate said ends, and wherein the bearing means located closest to said axial center comprises an axial bearing.
