(54) СПОСОБ ЭЛЕКТРОЭРОЗИОННОЙ ПРАВКИ ШЛИФОВАЛЬНЫХ КРУГОВ(54) METHOD FOR ELECTROEROSION EDITION OF GRINDING GRAPES

ба; на фиг. 2 - узел 1 на фиг. 1 fe увеличенном масштабе; на фиг.З схема правки по данному способу.ba; in fig. 2 — node 1 in FIG. 1 fe on a larger scale; on fig.Z scheme edits in this way.

- инструмент 1 с нанесенным токонепровод щим покрытием 2 на вспомогательную обращенную к счлифоВсшьному кругу 3 поверхность установлен под углом -об к радиусу круга в точке касани  вершины токонепровод щего покрыти  с заправл емой поверхностью шлифовального круга. Диэлектрическую жидкость 4 через сопло 5 подают на вращающийс  шливофальный круг, В процессе правки по мере зерен электрод - инструмент подают вперед микрометрическим устройством б/ закрепленным на кожухе 7 Шлифовального станка. Электрод - инструмент и шлифовальный круг изолирован друг от друга.и подключены к :элёkтpoиcкpoвoмy ,генератору. Одно временно с электроискровой правкой происходит шлифование детали 8. - tool 1 with applied non-conductive coating 2 on the auxiliary surface facing to the grinding wheel 3 is set at an angle - to the radius of the circle at the point of contact of the top of the non-conductive coating with the surface of the grinding wheel. The dielectric fluid 4 is fed through a nozzle 5 to a rotating shlyofalny circle. During the editing process, as the grains, the tool serves forward with a micrometer device b fixed to the casing 7 of the Grinder. Electrode - the tool and the grinding wheel are isolated from each other. And connected to: electric generator, generator. Simultaneously with the electric spark editing, grinding of the part 8 takes place.

Оптимальные результаты электроэрозионной правки достигаютс  при (. 30, при прочих равных параметрах правки. Уменьшение угла приводит к некоторому снижению производительности . процесса правки, а увеличение к снижению зерноудержани .Optimal EDM results are achieved at (. 30, all other parameters being equal. Editing results in a slight decrease in the productivity of the dressing process, and increases in grain retention.

Данный способ электроэрозионной правки позвол ет вскрывать зерна с особым расположением св зки вокруг Hftk: затылок на задней поверхностиThis method of electroerosive straightening makes it possible to open grains with a special arrangement of the ligament around Hftk: the back of the head on the back surface

зерна и лунка у передней поверхности .Затылок повышает жесткость закреп|лени  зерна, а лунка выполн ет роль стружечной канавки.the grain and the hole at the front surface. The nipple increases the stiffness of the grain, and the hole acts as a chip groove.

Применение насто щего способа электроэроэионной правки позвол ет снизить силы резани  при шлифовании правленным кругом соответственно в 1,3 и 1,1 раза и повысить стойкость шлифовальных кругов в 1,2 и 1,7 раза.The use of this method of electric power editing makes it possible to reduce cutting forces during grinding with a directed circle, respectively, 1.3 and 1.1 times and to increase the durability of grinding wheels by 1.2 and 1.7 times.
