Abstract

Изобретение относитс к области обработки металлов резанием и может быть использовано при чистовой обработке тел вращени на токарных станках. Целью изобретени вл етс повышение качества обработки на чистовых операци х путем срезани припуска с уменьшающейс толщиной. Цилиндрический многолезвийный инструмент 1 устанавливают под углом α к оси заготовки 2 и привод т в контакт с ней. Детали сообщают вращение с частотой N_т. Инструмент приводитс от нее во вращение с частотой N_в, определ емой частотой N_т и соотношением диаметров детали и инструмента. При радиальном сближении инструмента с деталью со скоростью V_SP происходит врезание на глубину прохода. После этого инструменту сообщают возвратно-поступательное движение со скоростью V_S вдоль оси детали на длину обрабатываемой поверхности. Срезание припуска производитс продольными 3 и боковыми 4 кромками зубьев инструмента 1, образованными канавками 7 и 8. При непрерывной радиальной и тангенциальной подачах срезание припуска осуществл етс уменьшающимис толщинами, что способствует равномерному износу режущих кромок и повышению качества обработанной поверхности. 2 с.п. и 2 з.п.ф-лы, 3 ил.The invention relates to the field of metal cutting and can be used in the finishing machining of bodies of revolution on lathes. The aim of the invention is to improve the quality of processing in finishing operations by cutting off the allowance with a decreasing thickness. A cylindrical multi-blade tool 1 is set at an angle α to the axis of the workpiece 2 and brought into contact with it. Details report rotation with frequency N _t . The tool is driven from it with a frequency of N _in , determined by the frequency of N _t and the ratio of the diameters of the part and the tool. When the tool approaches the part radially with the speed V _SP , a plunging into the depth of the passage occurs. After this, the tool is reported to reciprocate at a speed V _S along the part axis for the length of the surface to be machined. The cutting allowance is made by the longitudinal 3 and side 4 edges of the teeth of the tool 1, formed by the grooves 7 and 8. With continuous radial and tangential feeds, the cutting of the allowance is carried out by decreasing thicknesses, which contributes to uniform wear of the cutting edges and to an increase in the quality of the machined surface. 2 sec. and 2 hp ff, 3 ill.

Claims

Claim

A method of processing bodies of revolution with a self-rotating multi-blade tool, the axis of rotation of which is positioned at an angle to the axis of the part, which is reported to rotate around its own axis, characterized in that, in order to improve the quality of processing in finishing operations, the tool is informed of continuous reciprocating movement along the axis parts and depth feed.

2. The method according to π. 1, characterized in that the feed to the depth of cut is carried out continuously.

3. The method according to π. 1, characterized in that the supply to the cutting depth is carried out periodically at the end of each longitudinal movement.

4. A tool for processing bodies of revolution of the type of a cylindrical cutter, containing cutting teeth formed by intersecting grooves, characterized in that, in order to improve the quality of machining in finishing operations by cutting allowance with decreasing thickness, the grooves are made of a rectangular profile parallel to 'and perpendicular to the axis of the cutter, while the grooves located parallel to the axis of the cutter are deeper than the grooves located perpendicular to the axis of the cutter.
