CS273708B1 - Combined milling tool - Google Patents

Abstract

The principle of the combined tool for milling, composed of a clamping stop (3), an operation part with blades and a guiding smooth part, consists in the fact that the operation part is equipped with a combination of at least one smooth guiding bearing section (1) and at least one milling section (2) with blades, or the operation part is equipped with a higher number of alternately arranged smooth guiding bearing sections (1) and milling sections (2) with blades, while this milling section (2) is equipped with blades, or it is graved with diamond dust.<IMAGE>

Description

The invention relates to a combination tool 1c for milling materials and solves the problem of milling and deburring with the possibility of supporting the combination tool for milling on the workpiece.

There are known tools for milling materials consisting of a working part with cutting edges and a clamping part, which allow milling and deburring the desired surfaces without the possibility of supporting the tool against the functional surface of the workpiece.

This problem is solved by the combination milling tool according to the invention, comprising a shank, a working part with blades and a guide smooth part, characterized in that the working part is provided in combination with at least one guide smooth support section and at least one cutting milling section with blades. .

The combined milling tool preferably has two guide smooth abutment sections and a milling section consisting of diamond dust blades disposed therebetween.

The combined milling tool in a further preferred embodiment has two milling sections with cutting edges and a guide smooth abutment section positioned therebetween.

Advantages of the combination milling tool according to the invention include the possibility of performing a milling or grinding operation with a milling or grinding machine resiliently mounted with respect to a handling device, which may be a robot or a manipulator.

The combined milling tool according to the invention in an exemplary embodiment comprises one support and one milling section in FIG. 1, the order of the sections is changed from FIG. 1, in FIG. 3 the tool has two support sections and a milling section between them. FIG. 4 shows the tool with two milling sections and one guiding section.

In Fig. 1, they are arranged in a shank 2.

In Fig. 2, a shank 2 is shown in the shank 2, in which the functional part of the order guide smooth support section 1, the milling section 2 and the clamping is shown the combined milling tool, in which the functional part order rank the milling section 2, the guide smooth support section 1 and clamping section

Fig. 3 shows a combined milling tool in which the functional parts are arranged in the order of a guide smooth support section 1, a milling section 2, a guide smooth support section 1 and a clamping shank 2.

FIG. 4 shows a combined milling tool in which the functional parts are arranged in the order of a milling section 2, a guide smooth abutment section 1, a milling section 2 and a shank 2 »

The combination milling tool according to the invention in a particular embodiment has the shapes of the guide smooth abutment sections 1, the milling sections 2 and the clamping shank 2 formed by rotating a straight line and a general curve about the axis of the combined milling tool and various rotary radii. and fine machining, the milling sections 2 are provided with blades, covered with diamond dust, the shank 2 has a smooth surface.

The function of the combination milling tool according to the invention is that the combination milling tool is mounted in a milling or grinding machine, the milling or grinding machine being resiliently mounted relative to a handling device, which may be a robot or a manipulator. The handling device moves a resilient milling cutter or grinder with a combined milling tool according to the desired trajectory. Upon approaching the rotating milling combined tool to the work surface, the guide smooth support section 1 is supported on the functional surface of the workpiece and the milling section 2 performs a milling or grinding technological operation. The manipulation device by changing the position of the milling cutter or grinder with the combined milling tool can change the contact force applied to the combined milling tool. Arrangement of combined

CS 273708 B1 of the cutting tool according to the invention avoids damage to the workpiece on the workpiece.

The combined milling tool according to the invention is made of hard metals, sintered carbides, diamond grinding dust. On the milling section 2, fine cutting edges or a helical chip groove are formed, or diamond grinding dust is applied to the milling section 2.

The combination milling tool according to the invention finds application in mechanical engineering for the machining of spikes formed on workpieces in engineering theoheology where there is a functional surface close to the workpieces on which the combination tool can rest against the guide smooth support section 1, for example to deburr the tips after cutting. or grinding rails, tubes and similar profiles.
