Abstract

Использование дл  плоскопараллельной обработки деталей машиностроени  и электроники Сущность изобретени 1 станок содержит верхний 1 и нижний 2 притиры , приводимые в колебательное движение по круговым траектори м в противофазе от оппозитных эксцентриков вала 4. Верхний притир 1 соединен с силовым элементом 16 нажимного устройства 11 через подп тник 18 со смещенными плоскими кольцами Нижний притир 2 св зан с направл ющим устройством 5. Конструкци  обеспечивает полную сбалансированность сил резани  и инерции, отсутствие воздействи  на обрабатываемые детали со стороны сепаратора 3, равенство скоростей на всех участках рабочих поверхностей обоих притиров Это позвол ет эффективно обрабатывать особо тонкие и хрупкие полупроводниковые и керамические детали, а также производить взаимную правку притиров 3 илUse for plane-parallel machining of parts of mechanical engineering and electronics Essence of the invention 1 The machine comprises the upper 1 and the lower 2 lap, driven in oscillatory motion along circular trajectories m in opposite phase from the opposite eccentric shaft 4. The upper lap 1 is connected to the power element 16 of the pressing device 11 through the shed 18 with offset flat rings. The lower lap 2 is connected with the guide device 5. The design ensures a complete balance of cutting forces and inertia, no impact and the workpieces on the side of the separator 3, the equality of speeds on all parts of the working surfaces of both lap paints. This allows efficient processing of particularly thin and fragile semiconductor and ceramic parts, as well as mutual editing of ground lap 3 silt
