Claims (1)

Способ изготовления центровых отверстий, заключающийся в их сверлении центровочными сверлами и последующей пластической деформацией рабочих поверхностей, отличающийся тем, что сверление отверстий выполняют твердосплавными или быстрорежущими R-образными сверлами или сверлами с предохранительным конусом, затем обрабатываемую деталь ориентируют по центровым отверстиям и закрепляют в контейнере, отполированные твердосплавные центры с углом конуса 59°40'-59°50' с многослойным износостойким покрытием смещают в осевом направлении на заданную величину, затем центры выводят из отверстий, придают им вращение в противоположных направлениях, очищают и смазывают, вновь вводят в отверстия до упора с заданными осевыми усилиями и за несколько оборотов выглаживают рабочие поверхности отверстий, выводят центры, очищают и смазывают, подготавливая их для обработки следующей детали, а управление всеми исполнительными механизмами контейнера и установку заданных величин смещения при упрочнении и осевых усилий при выглаживании выполняют с помощью устройства с числовым программным управлением.A method of manufacturing center holes, which consists in drilling with center drills and subsequent plastic deformation of the working surfaces, characterized in that the holes are drilled with carbide or high-speed R-shaped drills or drills with a safety cone, then the workpiece is oriented along the center holes and fixed in the container, polished carbide centers with a cone angle of 59 ° 40'-59 ° 50 'with a multilayer wear-resistant coating are axially displaced by a predetermined th value, then the centers are removed from the holes, given to them in opposite directions, cleaned and lubricated, reinserted into the holes against the stop with predetermined axial forces and for a few turns smooth the working surfaces of the holes, the centers are removed, cleaned and lubricated, preparing them for processing of the next part, and the control of all actuators of the container and the setting of the specified displacement values during hardening and axial forces during smoothing are performed using a device with a numerical program control leniem.
