Устройство состоит из магнито- стрикщ-юнного преобразовател (ультразвукового вибратора) 1 с концентратором 2. Концентратор 2 через резиновые прокладки 3 жестко св зан с кожухом 4, эквидистантным концентратору 2. На .внутренней поверхности кожуха 4 жестко закреплены упругие элементы 5, контактирующие с боковой поверхностью концентратора 2. Между кожухом поверхностью концентратора 2 круговой канал 6.The device consists of a magnetostrictor transducer (ultrasonic vibrator) 1 with a hub 2. A hub 2 is rigidly connected through a rubber gasket 3 to the casing 4, an equidistant hub 2. On the inner surface of the casing 4 rigidly fixed elastic elements 5 that are in contact with the side the surface of the hub 2. Between the casing surface of the hub 2 circular channel 6.
В стбнке кожуха 4 по его периметру ) вьшолнена торцова полость 7, обращенна открытой стороной к режущей поверхиости и торцам абразивного инструмента 8. Дл подвода жидкости в круговой канал 6 и полость 7 на внешней поверхности кожуха 4 размещены патрубок 9 и штуцеры 10 и 11, св занные с системой подачи СОЖ (не показана ) . Наружна поверхность кожуха 4 покрыта слоем высокопористой резины 12. .In stbnke casing 4 along its perimeter) end face 7 is filled, facing with the open side to the cutting surface and the ends of the abrasive tool 8. For the supply of fluid in the circular channel 6 and the cavity 7 on the outer surface of the casing 4 there are nozzle 9 and fittings 10 and 11, st coolant system (not shown). The outer surface of the casing 4 is covered with a layer of highly porous rubber 12..

цом концентратора 2 устанавливаетс минимально необходимый зазор, в который из системы подачи СОЖ через патрубок 9 и канал 6 подаетс рабоча жидкость под давлением. Одновременно с вращением абразивного инструмента 8 через штуцеры 10 и 11 в полость 7 подаетс СОЖ под давлением , котора отсекает воздушные потоки от периферии инструмента и со всех сторон запирает рабочую жидкость в зоне очистки, поддержива там требуемое рабочее давление, которое становитс независимым от радиального зазора между режущей поверхностью и торцом концентратора 2.The hub of the concentrator 2 establishes the minimum required clearance into which the working fluid is supplied under pressure from the coolant supply system through the pipe 9 and channel 6. Simultaneously with the rotation of the abrasive tool 8, through the nozzles 10 and 11, coolant is supplied to the cavity 7 under pressure, which cuts off air flow from the periphery of the tool and locks the working fluid in the cleaning zone from all sides, maintaining the required working pressure there, which becomes independent of the radial clearance between the cutting surface and the end face of the hub 2.
Электричв ка энерги ультразвуковой частоты, вырабатываема ультразвуковым генератором, преобразуетс магнитострикционньм преобразователем 1 в механические колебани той же частоты, амплитуда которых усиливает-: с концентратором 2. Под действием механических колебаний торца концентратора 2 рабоча жидкость, наход ща с в зоне очистки, кавитирует и воздействует на режущую поверхность абразивного инструмента 8. При этом в joiiR очистки образуетс акустическое излучение кавитации, которое поглощаетс -запирающей струей СОЖ, а также демпфирующим покрытием кожуха.The electric power of the ultrasonic frequency produced by the ultrasonic generator is converted by a magnetostriction transducer 1 into mechanical vibrations of the same frequency, the amplitude of which amplifies: with concentrator 2. Under the action of mechanical vibrations of the end face of the concentrator 2, the working fluid in the cleaning zone cavitates and acts on the cutting surface of the abrasive tool 8. In this case, in the joiiR of cleaning, acoustic radiation of cavitation is generated, which is absorbed by the —a locking coolant jet, and also empathic coating casing.
Создание малого содержани газа в рабочей .жидкости, а также поддержание оптимального давлени в зоне очистки создают услови усиленного :.ф(}|скта кавитационной эрозии, что позвол ет повысить эффективность очистки режущей поверхности абразивных инструментов и пропитки при- )юверхностных объемов порового пространства. Попавша в поры кругаCreating a low gas content in the working fluid, as well as maintaining the optimum pressure in the cleaning zone, create enhanced conditions for cavitation erosion, which improves the cleaning efficiency of the cutting surface of abrasive tools and impregnation of pore volume above-volume volumes. Caught in the pores of the circle
СОЖ под действием центробежной силы выбрасываетс в виде мелких частиц, часть которых попадает в зону резани , активно воздейству на процесс шлифовани .The coolant is ejected by centrifugal force in the form of small particles, some of which fall into the cutting zone, actively influencing the grinding process.
