  • Arbor assembly
    Patent number: 4269553
    Abstract: PCT No. PCT/US80/00137 Sec. 371 Date Feb. 11, 1980 Sec. 102(e) Date Feb. 11, 1980 PCT Filed Feb. 11, 1980This invention relates to an arbor assembly (10) for attaching a cutting tool (14) to a machine spindle (12). Replacing large cutting tools on multiple spindle milling machines has, heretofore, been a costly, frustrating and time-consuming job that is often aggrevated by the inaccessable placement of the tool-holding spindles on a machine.The above problems are effectively solved by providing an arbor assembly (10) having a spindle adapter (16) attachable to a machine spindle (12) and a mating cutting tool adapter (18) that is attachable to a cutting tool (14). The cutting tool adapter (18) is laterally separable from the spindle adapter (16) and is of particular use with vertically oriented spindles on multiple spindle milling machines.
