Abstract

The invention relates to the production of tools and to the tool design of petal circles, in which the petals are mounted on a flexible ring case, and the case is connected to the hub by means of radial spokes. The purpose of the invention is to improve the quality of processing. For this, radial protrusions are made on the circle hub so that a part of the petals are supported by root parts on the protrusions. As a result, a predetermined rigidity of the petals is created in the circumferential direction. 3 il.

Vapa, for example, the tape is elastic. RST MSSR 28-70. Protrusions 3 can be 4-12. When the number of projections 3 is less than four, the possibility of providing different degrees of deformation of the petals 1 decreases. The number of projections 3 more than 12 complicates the manufacture and assembly of the circle. The width of all the projections 3 along the circle is the same; in this case, the protrusions 3 are of the same pattern, with a uniform line between the sides and the bottom. The circle is ready to go. For example, a circle, outer diameter.

When the work is done, the circle rotates, the detail is in.; And- (the contact with the abrasive surface of the petals 1, while the petals I, which are located above the corner of the shaft) do not interact with the bottom 7, they sinking and deform under the action of cutting forces .1 degree, in.

The use of the proposed petal-1 gallum-circle allows for an increase in the quality of processing by ensuring the appearance of uterTiuiH petal lobes with varying degrees of deformation and cutting forces.
