METHOD OF MILLING SLOTTED AND KEYED GROOVES ON THE INNER SURFACE OF THE SLEEVE USING A LATHE Russian patent published in 2019 - IPC B23C3/30 

FIELD: machine building.

SUBSTANCE: invention relates to mechanical engineering and can be used for milling slotted and keyed slots on the inner surface of bushings on lathes. On the support of the lateral feed of the lathe, the milling device is installed so that the axis of rotation of the mill is perpendicular to the axis of the height of the centers of the lathe and parallel to the direction of its transverse feed. Dividing head is installed on the machine bed in front of the headstock, in which the self-centering chuck fix the workpiece, while the center of the chuck should coincide with the axis of the height of the centers of the lathe. To install the cutter to the depth of milling using the feed cross-support machine. Using the longitudinal feed of the machine caliper in one or several passes, a longitudinal milling of the groove for the entire length of the sleeve is performed. For milling the next groove, turn the cartridge of the dividing head to the corresponding angle and repeat the previous operation. At the same time for milling grooves using cutters corresponding to the shape of the groove.

EFFECT: production of grooves of various profiles and sizes with high precision is provided using widely-used metal-cutting equipment.
