Abstract

The invention relates to mechanical engineering and can be used in the manufacture of shaped grinding wheels on a metal bond. The purpose of the invention is to expand the technological capabilities of editing grinding wheels due to the possibility of editing small circles. The method of dressing grinding wheels on a metal bond is carried out by plastic deforming the abrasive layer with two rolling tools of the counter profile. Circle 2 reported rotation due to the efforts of editing from one of the rolling tools, which is used as a coaxial circle drive disk 3.

Description

This invention relates to mechanical engineering, in particular to methods

straightening or profiling a grinding wheel on a metal link.

The purpose of the invention is to expand the technological capabilities of editing or profiling grinding wheels on a metal bond due to the possibility of editing small circles.

The drawing shows a scheme for implementing the method of editing or profiling a grinding wheel on a metal bond.

The housing 1 of the grinding wheel 2 is connected to the drive disk 3, the bolt 4 and the washer 5 with the possibility of relative rotation. The drive disk 3 has a working profile, which corresponds to the profile of the grinding wheel, and is mounted coaxially with the wheel housing 2. The rolling roller 6 is reported to move the feed S in the direction of the arrow, the grinding wheel 2 is rotated in the direction of the drive disk 3. Example 1. By a known method on a screw-cutting lathe model. The 1M61P was used to profile diamond grinding wheels on a metal bond with a diameter of 150 mm and a thickness of 0.7 mm in an amount of 3 pcs. The initial shape of the diamond layer is flat, the concentration of diamonds in the layer is 50%. The profile of the grinding wheel after processing is double conic sharpening with an angle of 60e. The profiling 45 was made by plastic deforming the diamond layer with two cones of a counter profile mounted on bearings. The grinding wheel was rotated, and the feed rollers were informed of the feed movement in the radial direction. In the process of rolling, the shredders were given a oscillating movement from the spring vibrator in the radial direction. The grinding speed was about 80–120 m / min;

Due to the low stiffness of the wheel, the residual deformations after profiling reached a significant value - face runout of 0.28–0.41 mm, which exceeds the permissible deviations of the shape of the grinding wheels and limits the technological capabilities of the known method.

Example 2. The Sh61P model turning and cutting machine of the proposed method is used to profile diamond grinding wheels on a metal bond with a diameter of 150 mm and a thickness of 0.7 mm in an amount of 3 pcs. The initial form of the diamond layer is flat, the concentration of diamonds in the layer is 50%. The profile of the grinding wheel after processing is double conic sharpening with an angle of 60 profile. The profiling is carried out by plastic deforming the diamond layer with two rolling tools of the counter profile. As one tool, use the knurling roller 6 of the mating profile, as the other tool use the drive disk of the mating profile coaxially around. The grinding wheel 2 is secured with a bolt 4 and a washer 5 on the mandrel of the drive disk 3 with the possibility of relative rotation. The grinding wheel is rotated by the straightening efforts of the drive disc 3, and the feed movement is reported to the knurling roller 6.

The circumferential speed of the grinding wheel 2 is 80-120 m / min, the rolling roller 6 is fed manually from the cross feed screw.

The final formation of the circle profile was carried out by reinstalling the circle 2 with the opposite side to the drive disk 3, fixing and plastic deformation with a knurled roller 6 under the above modes. The face beating of the diamond layer is 0.06-0.08 mm on both sides, which corresponds to the technical requirements for grinding wheels.
