Abstract
A tool for rotary chip removal machining includes a cutting head, a retention element and a shank. The cutting head includes a rear mounting portion and the retention element includes a front retaining portion. The mounting and retaining portion present forwardly facing and rearwardly facing surfaces, respectively, which engage one another for retaining the cutting head in the shank. The hook of the cutting head is asymmetrical with respect to the axis and is larger than the hook of the retention element. The cutting head includes a central flushing channel for conducting a flushing medium. The channel extends through the mounting portion of the cutting head for reducing the mass of that hook. The retention element includes a central channel which does not extend through the retaining portion.
Claims13
A milling tool for rotary chip removal machining comprising a shank defining an axis of rotation, a cutting head mounted in the shank and projecting forwardly therefrom along the axis, and a retention element for retaining the cutting head within the shank;
- a rear mounting portion of the cutting head being asymmetrical with respect to the axis and intersected by the axis, the rear mounting portion including a generally forwardly facing surface;
- the retention element mounted in the shank and including a front retaining portion asymmetrical with respect to the axis, the front retaining portion including a generally rearwardly facing surface engaging the generally forwardly facing surface of the cutting head;
- the cutting head including a cutting edge formed at a front end thereof;
- a rear channel extending axially through the retention element;
- a front channel extending axially through the cutting head and adapted to conduct a flushing medium to the front end, the channel extending through the rear mounting portion of the cutting head and intersecting the generally forwardly facing surface thereof.
A cutting head for rotary chip removal machining, the cutting head defining an axis of rotation and comprising a rear mounting portion having a generally forwardly facing surface;
- and a front portion having a cutting edge;
- the rear mounting portion being asymmetrical with respect to the axis and intersected by the axis;
- a channel extending axially through the cutting head and adapted to conduct a flushing medium to a front end thereof, the channel extending through the rear mounting portion and intersecting the generally forwardly facing surface thereof.
