Description

Изобретение относится к обработке резанием.The invention relates to machining.

Известен способ ротационного точения самовращающимся резцом, согласно кото—, рому дробление стружки осуществляют радиально перемещаемым несенным ножом[1].’A known method of rotary turning by a self-rotating cutter, according to which, the crushing of chips is carried out by a radially moved worn knife [1]. ’

Недостатком известного способа является нестабильность дробления стружки.The disadvantage of this method is the instability of crushing chips.

Цель изобретения - обеспечение надежного стружкодроблен ия.The purpose of the invention is the provision of reliable chip control.

Указанная цель обеспечивается тем, ^,0что обработку производят двумя, круглыми резцами, установленными эксцентрично друг над другом и вращающимися вокруг оси нижнего резца, причем частоту вращения резцов выбирают в зависимости от предель!⁵ной длины стружки.This goal is ensured by the fact that ^{, 0,} the processing is carried out by two, circular incisors mounted eccentrically one above the other and rotating around the axis of the lower incisor, and the frequency of rotation of the incisors is selected depending on the limit! ⁵ long chip lengths.

На чертеже изображено взаимное расположение резцов и заготовки и направления сообщаемых им движений.The drawing shows the relative position of the cutters and the workpiece and the direction of the movements communicated by them.

Для обработки заготовки 1 используют два круглых резца 2 и 3, которые вращаются вокруг оси 4 резца 2. Геометрическая ось 5 резца 3 смещена относительно оси его вращения 4. В процессе обработки заготовке 1 сообщают вращение вокруг оси 6, а резцам 2 и 3 - вращение по направлению схода стружки. Резцам сообщают также движение подачи S вдоль оси заготовки.To process the workpiece 1, two round cutters 2 and 3 are used, which rotate around the axis 4 of the cutter 2. The geometric axis 5 of the cutter 3 is offset relative to the axis of its rotation 4. During processing, the workpiece 1 is reported to rotate around the axis 6, and to the cutters 2 and 3 - rotation in the direction of the chip flow. The cutters are also informed of the feed movement S along the axis of the workpiece.

В процессе резания вследствие эксцентричной установки резца 3 толщина слоя срезаемого каждым резцом непрерывно меняется от максимального до минимального (нулевого) значения.In the process of cutting due to the eccentric installation of the cutter 3, the thickness of the layer cut off by each cutter continuously changes from maximum to minimum (zero) value.

В момент: минимального значения толщины срезаемого слоя на каждом из резцов происходит дробление стружки. За один оборот резцов стружка дробится дважды.At the moment: the minimum value of the thickness of the cut layer on each of the cutters, the chips are crushed. In one revolution of the cutters, the chips are crushed twice.

Использование способа обеспечивает надежное дробление стружки, что облегчает ее утилизацию и повышает безопасность труда.Using the method provides reliable crushing of chips, which facilitates its disposal and increases labor safety.

Claims

(54) METHOD OF ROTARY TURNING The invention relates to machining. The known method of rotational turning with a self-rotating cutter, according to KOTOI. Roma chip splitting is carried out by a radially moved incision knife 1. A disadvantage of the known method is the instability of chip splitting. The purpose of the invention is to provide reliable chip breaking. This goal is ensured by the fact that the treatment is carried out with two circular cutters installed eccentrically above (a fugue and rotating around the axis of the lower cutter, and the rotation frequency of the cutters is chosen depending on the limiting chip length. The drawing shows the relative position of the cutters to the workpiece and the direction movements reported to them. For machining the workpiece 1, two circular cutters 2 and 3 are used, which rotate around the axis 4 of the cutter.

2. The geometrical axis 5 of the cutter 3 is shifted relative to the axis of its rotation 4. In the process of machining, workpiece 1 is reported to rotate around the axis 6, and to the cutters 2 n 3 - rotation in the direction of chip flow. The cutters are also informed about the movement of the feed S along the axis of the workpiece. During the cutting process, due to the eccentric setting of the cutter 3, the thickness of the layer cut by each cutter continuously varies from maximum to minimum (zero) value. At the moment: the minimum thickness of the layer to be cut at each of the cutters, chips are crushed. During one revolution of the incisors, the chips are crushed twice. Using this method ensures reliable crushing of the chips, which facilitates their utilization and increases labor safety. The invention of the method of rotational turning, according to which the workpiece and the 1st reep of the soot and torsional movements, and the cutter feed movement along the axis of the workpiece, distinguish y and with hem, which, in order to ensure reliable chip breaking, the processing is performed by two round cuts | set eccentrically one above the other and rotating around the axis of the lower cutter, the frequency being rotational. 194 vibirayug incisors depending on the maximum chip length.
