MILLING CUTTER WITH BRACES

Abstract

The milling cutter according to the present invention consists of insert holders where these insert holders project from a carrier disc which is adapted for clamping onto the spindle of a machine tool, and the individual holders are connected with one another by braces. Arms are provided between the holders and the carrier disc,

Claims

1. A milling cutter comprising: (a) a carrier disc adapted for clamping onto a spindle of a machine tool; (b) a plurality of insert holders; (c) a plurality of braces that connect the insert holders; (d) a plurality of arms disposed between the insert holders and the carrier disc; (e) a collar that does not project beyond an envelope of inserts, wherein the insert holders are arranged around the collar; and (f) a plurality of stiffeners disposed between the insert holders and the collar, further comprising struts disposed between the arms and the braces, with each strut connecting a respective one of the arms to a respective one of the braces.

3. The milling cutter according to claim 1, further comprising nozzles protruding from the carrier disc.

4. A milling cutter comprising: (a) a carrier disc adapted for clamping onto a spindle of a machine tool; (b) a plurality of insert holders spaced circumferentially relative to one another; (c) a plurality of braces that connect the insert holders; (d) a plurality of arms, with each arm connecting the carrier disc and a respective insert holder; (e) a collar that does not project beyond an envelope of inserts, wherein the insert holders are arranged around the collar; and (f) a plurality of radially-extending stiffeners connected to the collar and to respective insert holders.

5. The milling cutter according to claim 4, further comprising struts disposed between the arms and the braces.

6. The milling cutter according to claim 5, each of said struts connecting a respective one of the arms to a respective one of the braces.

[0009] A general view of the milling cutter from the carrier disc side using axonometric projection is shown in FIG. 1, with the inserts omitted; a front view from the side of the holders of exchangeable inserts is in FIG. 2; another view from the side of the carrier disc is shown in FIG. 3 and a view from the side of the holders of inserts using axonometric projection is in FIG. 4.

DESCRIPTION OF EXAMPLE EMBODIMENT

[0010] The milling cutter consists of insert holders 2 where the holders 2 project from carrier disc I which is adapted for clamping onto the spindle of a machine tool. The holders 2 are connected with one another by braces 3. Arms 5 are provided between the holders 2 and carrier disc 1, struts 4 are provided between the arms 5 and braces 3. Holders 2 are arranged around and connected by stiffeners 7 to the collar 6, which does not project beyond the envelope of the inserts. The inserts are not shown on the drawing; their attachment to the holders 2 is outside the scope of this invention. Leading from the carrier disc I, which is provided with a process fluid inlet, are tubes with nozzles 8 which are aimed at faces of the inserts. The milling cutter is also provided with balancing attachments 9 which comprise bushings with adjustable weights. The balancing attachments 9 compensate for the non-uniform distribution of the tool weight and their design is outside the scope of this invention.
