Description

This invention relates to metal cutting tool designs.

A disc milling machine is known, holding the case with axial grooves intersecting the end surfaces, each of which has the parts of the tool assembly, the tool holder with the cutting element and the fastening wedge, which have support shoulders protruding beyond the groove and interacting with 10 basic parts. housing surfaces. The collar of the holder extends beyond the groove in the axial direction and interacts with the end surfaces of the body a, and the collar of the wedge protrudes 15 in the tangential direction and interacts with the surface of the specially made groove ij.

This milling cutter ensures the fixation of parts of the mounting unit relative to the 20 base surfaces of the housing in a strictly defined position.

A disadvantage of the known milling cutter is the low rigidity of the structure, determined by the need to reduce the size of the bearing surface of the grooves in contact with the holders in the direction of the cutting forces. Insufficient rigidity prevents the increase of cutting conditions and, as a result, machining performance.

The purpose of the invention is to increase the productivity of processing by increasing the rigidity of the cutter design.

This goal is achieved by the fact that in a milling cutter disk containing a body with axial grooves intersecting the end surfaces in each of

parts of the incisal node are installed, having supporting flanges protruding beyond the groove and interacting with basic Kopnyqa surfaces, annular grooves intersecting axial grooves are made on the end surfaces of the housing, and the supporting shoulders of the incisal node protrude beyond the groove radially.

FIG. 1 shows a disk cutter; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4-- section B in FIG. one.

The milling cutter consists of a body 1 with axial grooves 2, in which the parts of the cutting nodes are located - holders 3 with cutting plates 4 and fastening wedges 5.

On the end surfaces 6 of the casing there are annular grooves 7, the axial grooves intersecting and forming the base surfaces 8. The holders and fastening wedges have support flanges 9, which interact with the said base surfaces.

The interaction of the shoulders with the base surfaces ensures the fixation of the parts of the mount in a certain position relative to the housing, and the arrangement of the shoulders of the annular grooves of the housing — the maximum surface area of the 10 slots.

The invention contributes to increasing the rigidity of the structure and, as a result, processing performance.
