First, a mixture of crystalline graphite with liquid is prepared and fed into a device for producing a graphene-containing suspension by shearing exfoliation of particles of graphite with a field of centrifugal forces occurring between cylindrical stator 1 and rotor 2 with radial blades rotating from rotary drive 3. Stator 1 is made in the form of cylindrical shell with holes. Cylindrical shell of stator 1 has cover 5 and is divided into two zones in height. Holes are located only in the upper zone. Height of lower zone is 2 to 5 times larger than height of upper zone. Holes on outer surface of stator 1 have countersink grooves 0.7–0.9 of depth of cylindrical shell, with angle of 60 to 120 degrees. Rotor 2 has slots in which moving blades 4 in the form of plates with holders of their vertical movement are installed. On the end side adjoining the inner surface of stator 1, blades 4 have chamfers at an angle of up to 45°, due to which it is possible to create constant normal and tangential forces that are independent of graphite particle size.

Abstract: Изобретение относится к машиностроению и может быть использовано для абразивной обработки коротких сквозных отверстий деталей. Хонинговальную головку вращают и перемещают в продольном направлении с реверсированием в конце каждого хода при выходе брусков из обрабатываемого отверстия. Обработку сквозного отверстия осуществляют с двух противоположных сторон детали путем ее периодического переворота обрабатываемой детали. Цикл хонингования разделяют как минимум на два или более подциклов, в каждом из которых обработку выполняют с разных сторон детали. Время каждого подцикла определяют в зависимости от погрешности формы отверстия в продольном направлении после выполнения предыдущего подцикла и средней скорости съема материала.
