Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] A reverse milling cutter, comprising a milling cutter handle 11, a milling cutter head 12, and a stop pin 13, the milling cutter handle 11, and the stop pin 13 are all revolving body structures, and the milling cutter head 12 is a partial revolving body structure, and the milling cutter One end of the handle 11 is provided with a through hole along the radial direction of the handle. After the rotary shaft of the milling cutter handle 11 passes through the inner hole of the milling cutter head 12, it is precisely matched with the inner hole of the milling cutter head 12, and the stop pin 13 passes through the through hole on the milling cutter holder 11. The center of the milling cutter head 12 is provided with a combined hole formed by a through hole and a square groove. One axial side of the milling cutter head is provided with a cutter head, and the other axial si...

Abstract

The invention discloses a reverse milling method. The method comprises the following main steps: a reverse milling handle is inserted into a counterbore of a part, a reverse milling tool is combined,a reverse milling cutter shank is mounted to a spindle of a milling machine, after the spindle of the milling machine rotates, the tool is axially fed to a certain cutting depth then retracted, the reverse milling tool is dismounted, and machining of the small counterbore is completed. The problem that a reverse counterbore cannot be machined by the traditional conventional tool is solved.

Description

technical field [0001] The invention relates to a reverse milling process, in particular to a reverse milling method. Background technique [0002] At present, in mechanical processing, there is no corresponding tool and processing method for countersunk hole processing. Conventional processing methods and tools will interfere with the tool when machining the countersunk hole, and this problem cannot be solved. At present, the backside of the small hole is mainly processed by white steel knife back scraping, but for the countersunk hole processing that is too small, the tool handle will be too small, the cutting force will be insufficient and the knife will be broken. The backwashing processing method of the present invention combines a Reverse milling cutter to complete countersunk hole processing. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a reverse milling method, which uses a reverse milli...
