SU1207727A1 - Method of working an opening with inclined generatrix - Google Patents

Description

This invention relates to riponi-water optical components and can be used in the manufacture of optical blends.

The purpose of the invention is to make the quality of an orifice with an oblique generatrix shaped like a Hellens by using a tool, the axis of which is perpendicular to the axial line of the orifice and the following profile.

, 2B - the axis of the tool profile is small.

The workpiece (diaphragm) 1 is installed in the fixture on the machine table, so that the flat part of the workpiece (diaphragm) is parallel to the axis of the rotating tool. The tool 2, which has cutting properties, is installed on the spindle 3 of the profile grinding or horizontal milling machine and informs it of the rotational movement, and the projection axis of the rotating tool (or spindle 3 of the machine) aligns

Due to the indicated abilities of the tool used, the location of its axis perpendicular to the axial line of the hole and moving it parallel to this line, the quality of the hole is improved by achieving a full correspondence between the dimensions of the axis of the hole and the angle of inclination.
