Description

Изобретение относитс  к области станкостроени  и металлообработки.The invention relates to the field of machine tools and metalworking.

Известен способ чистовой обработки жело-. ба наружного кольца шарикоподшипника, по которому ось инструмента располагают параллельно оси издели  и ввод т в него движением , параллельным его оси, и далее радиальным движением осуществл ют быстрый подвод инструмента к обрабатываемой поверхности и рабочую подачу.The known method of finishing treatment is cel-. The ball bearing outer ring, on which the tool axis is located parallel to the product axis and is inserted into it in a movement parallel to its axis, and then radially moves the tool to the surface to be machined and the work feed.

Предлагаемый способ обработки отличаетс  от известного тем, что подвод инструмента к изделию и рабочую подачу осуществл ют одним круговым движением, при этом ось поворота шпиндел  инструмента располагают от оси издели  на рассто нии, равном радиусу круговой оси желоба издели , а ось вращени  инструмента располагают по отношению к оси издели  под определенным углом, завис щим от параметров обрабатываемой поверхности издели  и инструмента.The proposed processing method differs from the known fact that the tool is brought to the product and the work feed is carried out in one circular motion, while the axis of rotation of the tool spindles is positioned from the product axis at a distance equal to the radius of the axis of the tool groove, and the axis of rotation of the tool is to the axis of the product at a certain angle, depending on the parameters of the processed surface of the product and tool.

Это позвол ет повысить производительность обработки и срок службы инструмента.This improves processing performance and tool life.

Изобретение по сн етс  чертежом.The invention is illustrated in the drawing.

Дисковый инструмент 1, рабоча  поверхность которого имеет профиль, соответствующий профилю обрабатываемого желоба издели  2, вращают вокруг собственных осей, а инструмент 1 подвод т к обрабатываемой поверхности и далее осуществл ют рабочую подачу одним поворотным вокруг оси 3 движением . Дл  получени  возможно большего диаметра инструмента без ухудшени  условий обработки размещают ось поворота щлифовального шпиндел  от оси вращени  издели  на рассто нии, равном радиусу круговой оси желоба издели , а ось вращени  инструмента располагают по отношению к оси издели  под углом у, завис щим от параметров обрабатываемой поверхности издели  и инструмента и определ емым по формулеThe disk tool 1, the working surface of which has a profile corresponding to the profile of the chute of the product 2 to be machined, is rotated around its own axes, and the tool 1 is guided to the surface to be machined and then the working feed is carried out by one rotary motion around the axis 3. To obtain the largest possible tool diameter without degrading the machining conditions, the axis of rotation of the grinding spindle from the axis of rotation of the product is placed at a distance equal to the radius of the circular axis of the groove of the product, and the axis of rotation of the tool is positioned with respect to the axis of the product at an angle y product and tool and defined by the formula
