Problems solved by technology
When machining the outer arc surface of the part, the existing technology generally rough-machines the outer arc surface of the part by scribing, and then files the outer arc surface to meet the requirements of the drawing by a fitter. This processing method is inefficient and prone to quality problems. Problems that affect the normal delivery of parts

The invention relates to a tool used for machining an outer arc surface of a part, in particular to a tool used for efficiently machining an outer arc surface of a part. The tool is of a fluted disc structure, and a mounting hole is formed in the center of the tool. The fluted disc structure comprises a center disc and a plurality of tool teeth annularly distributed on the circumference of the disc. Each tool tooth is provided with a concave arc blade towards the center of the disc, and the projection of each arc blade in the axial direction is a straight line. During machining, a cylindrical handle (3) of the part with the outer arc surface is clamped, a disc milling cutter is mounted on a common horizontal milling machine tool, the center, namely the machining datum, of the cylindrical handle (3) is aligned, and machining of the outer arc surface (1) of the part is achieved.
Description
technical field [0001] The invention relates to designing a tool, in particular to a tool for machining the outer arc surface of a part. Background technique [0002] The existing technology often involves the processing of the outer arc surface of the part, see figure 1 , this outer arc surface part is composed of an outer arc surface 1, an inner arc groove 2 and a cylindrical handle 3. When machining the outer arc surface of the part, the existing technology generally rough-machines the outer arc surface of the part by scribing, and then files the outer arc surface to meet the requirements of the drawing by a fitter. This processing method is inefficient and prone to quality problems. Problems that affect the normal delivery of parts. Contents of the invention [0003] The object of the present invention is to provide a tool for machining the outer arc surface of a part. [0004] The technical solution of the present invention is: a tool for machining the outer arc su...
