Milling tool with rotatable cutting disks

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.

Cutting tool with replaceable cutting edges and cutting inserts for said tool

FIELD: process engineering. SUBSTANCE: set of invention relates to machine building and can be used for machining by tool with replaceable cutting edges at high feeds. Proposed tool comprises body, plug-in inserts and multiple insert seats with surface of bottom wall and multiple sections of top walls hanging above appropriate insert seat and having side surface defining the chips pocket. Every said section hangs over to cover at least the insert part in said seat and is configured so that amount of hanging over on base side is larger than that whereat top wall section hangs over the insert seat on its front end. Top wall section is formed to increase the depth of section for support of insert in said seat abutting on appropriate insert seat and extends from insert seat bottom wall surface to abut on appropriate insert seat and on top wall section side surface.
