The vibratory processing granule contains a core 1 on which parts of the shell with the stripping elements 2 are placed, the shell being made in the form of rings connected to the core 1, and the rings can be installed with an increase in diameter towards the center of the core 1 with an increase in the thickness of the rings in the direction of the ends of the core 1, can be located with the formation of helical rows at the places of fastening 3 with the core 1. In addition, the rings can be installed with an angular rotation relative to each other, and the core 1 flax in the form of parts interconnected by an elastic element 4.

The manufacture and assembly of granules is carried out as follows. Rings are made, for example, by cutting a cylindrical spring into separate turns, followed by straightening and fastening of the ends into a ring, for example, by welding. The cross section of the rings can be either round or rectangular, while the ring can be obtained, for example, by cutting from a metal tape on a stamp. The core 1 can be obtained, for example, by cutting metal sections with scissors, for example, a round or rectangular profile, or, for example, can be made by cutting on a stamp from a metal tape, while the fastening of the rings with the core 1 can be performed, for example welding, and the rings relative to the core 1 can be arranged as follows: with an increase in diameter towards the center of the core 1, with an increase in the thickness of the rings in the direction of the ends of the core 1, with the formation of helical rows 3 where bonding with the core of an 1, with steer angle relative to each other. The core 1 can be made not integral, but consisting of separate parts, while the fastening of the individual parts to each other is done using an elastic element 4, for example, a cylindrical spring or a conical spring can be used as the elastic element 4, and the fastening itself is made , for example, by welding. The number of elastic elements 4 can be taken up to five; with a larger number of them, the production of granules is complicated. The number of rings placed on the core 1 can be 7-100 and depends on the size of the granule, as well as on the method of placing the rings around the core 1, while the rings are placed in russes to ensure that the stripped parts pass through them parallel to the axis of the core 1, the number of rings in

Rousse can be from one to four and

depends on the dimensions of the rings and core 1,

 In addition, in the Rus can be installed

rings of different diameters. At the ends of the core 1, a ring is mounted so that the plane of the ring is parallel to the axis of the core 1. The rings can be made, for example, of steels with spring properties. Distance between Rus

0 rings are taken from the condition of providing the best vibration characteristics, as well as from the condition of making it possible to bond the rings to the core 1. After the rings are fastened

5 with a core 1, stripping elements 2 are applied to the surface of the granule, for example by galvanic deposition of a diamond-containing layer. The pellet is ready to go. Diameter (core 1 is assigned from the condition

0 providing the pellet lasting characteristics as well as the best vibrational characteristics. The diameter of the hole of the rings is taken from the condition that the machined parts free fall through them. Rings relative to each other can be installed with a turn of ± 30 °.

For example, a granule consists of 35 rings with a hole diameter of 20 mm and a diameter

0 wire cross-sections - 2 mm, Material - steel 65С2ВА, the distance between the fastening points 3 along the axis of the core is 1-6 mm, the number of rings in the rue is 3, the diameter of the core is 1-8 mm, the core material is 5 ZOKHGSA steel, the core length is 70 mm, the diameter of all installed rings is the same, the thickness of all rings is the same, the rings are installed without an angular rotation relative to each other, the cleaning elements 2 are deposited by galvanic deposition of a diamond-containing layer M28, the dimensions of the workpieces are 10x14x18 mm, the rings are bonded with core 1 using arch.

5 During processing, the granules are loaded together with the workpieces into a vibrocontainer, a device is turned on that moves the vibrocontainer into the spatial vibrocontainer,

Q, the surfaces to be cleaned contact the surface of the elements 2 to be cleaned and parts are machined, while the surface elements 2 of the rings are able to perform different-frequency vibrational vibrations, as well as random movement along the volume of the container. After finishing the processing, granules and processed parts are separated, for example, using special separation gratings.

The use of granules for vibration processing improves the processing productivity by increasing the range of vibration frequency characteristics due to; making the granule shell in the form of a three-dimensional structure consisting of cells having the ability to perform vibrational vibrations of different frequencies due to the execution of cells in the form of rings fastened to the rod; providing granule shell elements with the ability to perform different frequency vibrational vibrations due to the possible implementation of granule rings of different diameters and cross-sections; providing granule shell elements with the ability to oscillate as a result of a small contact surface when the rings are bonded to the core; providing the granule elements with the ability to make different-frequency vibrational vibrations due to the lack of additional vibration sources in the form of elastic elements placed between the parts of the core, as well as increasing the processing productivity by increasing the contact surface of the treated surfaces with the cleaning elements due to the possible additional contact of the processed parts by external contour as a result of the possibility of parts falling through the holes of the rings, since the holes to the rings have large dimensions, compared with the workpieces, increasing the duration of contact of the treated surfaces with the cleaning elements when parts get inside the rings as a result of the possible location of the rings on the rod with the formation of helical rows

in places of bonding, increasing the duration of contact of the treated surfaces with the cleaning elements when the part gets inside the rings as a result of the possible installation of the rings with an angular turn relative to each other.

In addition, technological capabilities are expanded due to the processing of hard-to-reach places in the form of grooves, crevices, convenience of separation of the processed parts and granules, as well as ease of manufacture.
