SU1335428A1 - Method of orienting a grinding wheel for grinding grooves in metal-working tools - Google Patents

Abstract

The invention relates to the grinding of grooves of metal-cutting tools. The purpose of the invention is to increase grinding performance. When processing grooves whose width exceeds the height of the circle, the latter is turned at an angle to the direction of the axis of the groove. At the same time, the reversal process is carried out along the profile of the reference article, successively bringing the circle into contact with the bottom and side walls of the reference groove. In this way, the groove of the tool is machined in such a manner. 2 Il. a (L MTR averaged 4: to 00 FIG.

Description

11335428

The invention relates to the field of grinding and can be used when grinding the grooves of metal-cutting tools.

The purpose of the invention is to improve grinding performance by reducing the time for determining the turning circle of a circle when machining grooves having a cross-section perpendicular to the groove direction, an ellipse circumference profile.

FIG. 1 shows the orientation process of the product, end view; in fig. 2 - the same, top view.

The method is implemented as follows.

The circle thus unfolded is removed from the groove and the reference article is replaced with an instrument that needs to be rebuilt. SEND

rotational circle reported

and moving in the direction of the axis of the groove, carried out its processing.

Claims (1)

10 claims The method of orientation of the grinding wheel when grinding the grooves of metal-cutting tools, in which the grinding wheel of the corner profile, whose height is less than the width 15 The reference product 1 with a groove, the profile with the profile corresponds to the profile of the groove of the workpiece, is placed on the machine table and the grinding wheel 2, which is less than the width of the groove 3, is brought into contact with the bottom of the groove, placing the axis of symmetry of the profile of the circle 2 with the axis of symmetry of the groove 3, then the circle is unrolled until it touches the walls of the groove. The direction of the reversal is carried out taking into account the direction of the velocity vector V in the direction of a strong section.  grooves, rotate to the direction of the groove axis at an angle, characterized in that, in order to increase the NIN of productivity by reducing the time for determining the turning circle of a circle, when processing grooves having a section perpendicular to the groove direction, the ellipse circumference profile is taken, The groove profile of which is identical to the groove profile of the tool to be machined, and the grinding wheel is brought into contact with the bottom of this groove, after which the wheel is turned to the most contact with the side walls avki. The circle thus unfolded is removed from the groove and the reference article is replaced with an instrument that needs to be rebuilt. SEND rotational circle reported and moving in the direction of the axis of the groove, carried out its processing. 10 claims The method of orientation of the grinding wheel when grinding the grooves of metal-cutting tools, in which the grinding wheel of the corner profile, whose height is less than the width Editor E.
