Milling Tool With Rotatable Cutting Disks

摘要

A milling tool having multiple cutting disks is disclosed. Each cutting disk is anchored into a flute on the milling tool with clamping screws. During use, the cutting disks naturally become dull. In a preferred embodiment, a single clamping screw is used to hold the cutting disk in place. The clamping screw is loosened and the cutting disk is rotated such that a new and sharp portion of the cutting disk is exposed for use. In an alternative embodiment, multiple clamping screws are used to secure the cutting disk into the flute. In the event a cutting disk becomes stuck in a flute, a clamping screw in a threaded bore coaxially aligned with the locating bore is used to push the cutting disk and eject it out of the flute. This design allows for many positions on the cutting disk to be used before the disk needs to be replaced, sharpened, or refurbished.

1. A milling tool comprising:
a circular tool body having an outer edge, a thickness, and a front face that defines a front plane; a plurality of flutes extending outward from the outer edge having a leading face and a trailing face, wherein the leading face and trailing face define a direction of rotation; a locating bore located in the approximate center of the lead face of each flute and extending through the flute to the trailing face; a threaded hole located on each flute extending into a midsection of the locating bore; a cutting disk having a cutting edge and a clamping pin configured to be inserted into the locating bore from the front face of a flute; and a screw inserted into the threaded hole and configured to engage a portion of the clamping pin.
