Изобретение относитс к области механической обработки деталей и может быть использовано дл обработки поверхности деталей со сквозными капилл рными отверсти ми, например микроканальных пластин, полученных методом выт гивани и спекани полых трубок.The invention relates to the field of machining parts and can be used to process the surface of parts with through capillary holes, such as microchannel plates, obtained by extruding and sintering hollow tubes.
Известен способ обработки таких микроканальных пластин. Недостатком этого способа обработки вл етс необходимость предварительного заполнени капилл ров воском дл предупреждени засорени их шламом во врем обработки. После обработки поверхностей микроканальных пластин требуетс выплавление воска из капилл ров и тем самым увеличиваетс количество операций и врем обработки .There is a method of processing such microchannel plates. The disadvantage of this treatment method is that it is necessary to pre-fill the capillaries with wax in order to prevent their clogging with sludge during processing. After processing the surfaces of the microchannel plates, wax is required to melt out of the capillaries and thereby the number of operations and the processing time increase.
Цель изобретени - предотвращение засорени капилл ров шламом.The purpose of the invention is to prevent clogging of the capillaries with sludge.
Дл этого вместе со смазывающе-охлаждающей жидкостью (СОЖ) шлам принудительно прогон ют через капилл ры, дл чего деталь располагают на рассто нии от центра враш,ени инструмента, определ емом необходимой величиной превышени давлени жидкости в капилл ре над силой поверхностного нат жени жидкости на выходе из капилл рного отверсти .To do this, together with the lubricating coolant (coolant), the sludge is forced through the capillaries, for which the part is located at a distance from the center of the tool, determined by the required value of the excess pressure of the liquid in the capillary above the surface tension force of the liquid outlet from the capillary orifice.
При использовании движущейс жидкости в процессе обработки получают детали, капилл рные отверсти которых не засорены шла мом.When using a moving fluid in the process, parts are obtained whose capillary openings are not clogged with slime.
Способ по сн етс чертежом. Дл обработки поверхностей микроканальных пластин используют абразивный инструмент и подачу жидкости. На обрабатывающий абразивный инструмент 1 устанавливают микроканальную пластину 2 в оправе 3, котора не закрывает отверстий капилл ров, включают подачу жидкости из шланга 4 в зону обработки , а затем вращение инструмента. При включении подачи жидкости последн поднимаетс по капилл рам микроканальной пластины. При включении вращени инструмента жидкость приобретает кинетическую энергию. Когда возникает превышение давлени жидкости в капилл ре над силой поверхностного нат жени жидкости на выходе из капилл рного отверсти , жидкость выливаетс из капилл ров, выносит частицы шлама, преп тствует цементации этих частиц в капилл рах . При обработке дл равномерности съема микроканальной пластине придают возвратно-поступательное перемещение. ПослеThe method is explained in the drawing. An abrasive tool and a liquid feed are used to treat the surfaces of the microchannel plates. A microchannel plate 2 is mounted on the processing abrasive tool 1 in the frame 3, which does not cover the capillary openings, turn on the fluid from the hose 4 to the treatment area, and then rotate the tool. When the fluid supply is turned on, the latter rises through the capillaries of the microchannel plate. When turning on the rotation of the tool, the liquid acquires kinetic energy. When the fluid pressure in the capillary rises above the surface tension of the fluid at the outlet of the capillary orifice, the fluid is poured out of the capillary, carrying sludge particles, preventing the carburization of these particles in the capillaries. When processing for uniform removal of microchannel plate give the reciprocating movement. After
обработки выключают вращение шпиндел инструмента, а затем подачу жидкости. Капилл ры детали очищают сжатым воздухом от жидкости и взвешенных в ней частиц щлама.processing off the rotation of the spindle tool, and then the flow of fluid. Capillaries of parts are cleaned with compressed air from liquid and suspended matter particles in it.
По предлагаемому способу производ т механическую обработку поверхностей деталей (шлифовку и полировку) без остановки процесса дл промежуточной очистки капилл ров . Получают детали с малым числом или вообще без заполненных капилл ров за счет посто нного отвода шлама жидкостью из зоны обработки. Примен ют скоростные методы обработки за счет охлаждени жидкостью.In the proposed method, the surfaces of the parts are machined (grinding and polishing) without interrupting the process for intermediate cleaning of the capillaries. Parts with a small number of or without any filled capillaries are obtained due to the constant removal of sludge by liquid from the treatment zone. High-speed processing methods are employed by cooling with liquid.
