Abstract

The invention relates to the manufacture of an abrasive tool, in particular cutting wheels used for cutting various non-metallic materials. The aim of the invention is to increase tool life by creating conditions equal to the strength of the body in the radial direction. The tool body consists of concentrically arranged rings 1 and 2, around which wire / or thread / 3 is wound. Abrasive elements 4 are fixed on the body. The coils are closed laterally with protective discs 5 and 6, the installation of which provides additional adjustment of the thread tension by bringing opposite turns . 1 hp ff, 4 ill.

The invention relates to the production of abrasive tools, in particular abrasive cutting wheels, and can be used to cut various non-metallic materials, such as building natural facing stones, semiconductor and dielectric single crystals, etc. 10

The purpose of the invention is to increase tool life by creating conditions equal to the strength of the body in the radial direction.

In figures 1 and 2 presents the cutting circle 15 with an inner cutting edge, a general view, a projection; Figs, 3 and 4 - cutting disc with an outer cutting edge, the projection

and it is about cutting materials according to the technology.

Similarly, a p-circle with an outer cutting edge (FIGURES and 4) is used. Discs 5 and 6 provide for the displacement of the branches of the continuous thread in the zone between the concentric rings parallel to the axis of rotation of the tool, which provides additional tension on the threads and creates conditions for adjusting the equal strength of the body in the radial direction. The thickness of the disks must be such that the distance between their front sides is less than the width of the abrasive elements.

The use of the invention allows the Instrument to contain the Case, the condition is to create conditions equal to the strength of concentric rings (outer 1 and inner 2), around which the wire (or thread) is wound 3

In the tool with an internal cutting edge (FIGS. 1 and 2), the abrasive elements 4 are placed on the surface of the body formed by the inner ring 2 and the turns 3

In the tool with the outer cutting edge (FIGS. 3 and 4), the abrasive elements 4 are placed along the peripheral surface of the body formed by the ring 1 and the turns 3 Discs (covers) 5 and 6 cover the turns 3 of the body on two end sides, protecting them from possible damage during transportation and operation ,,

The landing flange 7 is installed along the inner surface of the housing. On this principle, structures of circles and other profiles, for example, the type of AMS

The tool (FIGS. 1 and 2) works as follows.

An abrasive disc with an inner cutting edge is installed and secured in the chuck of the cutting machine.

tool housings in the radial direction with the possibility of adjusting the tension of the threads

Claims (1)

Invention Formula thirty 35 1 Abrasive tool, made in the form of a body bearing an abrasive element, consisting of two concentric rings connected by radially arranged elements and placed on its ends of covers, characterized in that, in order to increase tool life by creating conditions equal to the strength of the body in the radial the direction, the radially arranged elements are made in the form of turns of wire, while the knots are mounted in contact with the turns of the wire, and the latter in the zone between the rings are located in one plane . 2 o The tool according to claim 2, characterized in that the distance between the end surfaces of the covers is smaller than the width of the abrasive elements. 40 and it is about cutting materials according to the technology. Similarly, a p-circle with an outer cutting edge (FIGURES and 4) is used. Discs 5 and 6 provide for the displacement of the branches of the continuous thread in the zone between the concentric rings parallel to the axis of rotation of the tool, which provides additional tension on the threads and creates conditions for adjusting the equal strength of the body in the radial direction. The thickness of the disks must be such that the distance between their front sides is less than the width of the abrasive elements. Use of the invention allows tool housings in the radial direction with the ability to adjust the tension of the threads Invention Formula 1 Abrasive tool, made in the form of a body bearing an abrasive element, consisting of two concentric rings connected by radially arranged elements and placed on its ends of covers, characterized in that, in order to increase tool life by creating conditions equal to the strength of the body in the radial the direction, the radially arranged elements are made in the form of turns of wire, while the knots are installed in contact with the turns of the wire, and the latter in the zone between the rings are located in the same plane . 2 o The tool according to claim 2, characterized in that the distance between the end surfaces of the covers is smaller than the width of the abrasive elements.
