Abstract

The invention relates to a ball head milling cutter, in particular to a ball head milling cutter for splicing die milling so as to solve the problems that in the cutting process, an existing rotary milling cutter is large in cutting force and large in vibration, consequently, the cutter is seriously abraded, and the machining quality is poor. A body is provided with spiral cutting blades. A front cutter face 1, a first rear cutter face 1 and a second rear cutter face 1 are arranged on the two sides of a first cutting blade. A front cutter face 2, a first rear cutter face 2 and a second rear cutter face 2 are arranged on the two sides of a second cutting blade. The upper surface of the body is connected with a first main groove hook face and a second auxiliary groove hook face. A transition part of the front cutter face 1 and the first main groove hook face is a first scrap containing groove, and the second auxiliary groove hook face is connected with the second rear cutter face 2. The lower surface of the body is connected with a second main groove hook face and a first auxiliary groove hook face, the transition part of the front cutter face 2 and the second main groove hook face is a second scrap containing groove, and the first auxiliary groove hook face is connected with the second rear cutter face 1. The ball head milling cutter is used for milled piece machining.

Description

technical field [0001] The invention relates to a ball-end milling cutter, in particular to a ball-end milling cutter for splicing mold milling, in particular to a helical-blade ball-end milling cutter with an impact resistance and wear resistance for processing splicing molds. Background technique [0002] The ball end milling cutter is a tool with a blade similar to a ball end and assembled on a milling machine for milling various curved surfaces and arc grooves. Ball end milling cutter is also called R cutter. Ball end milling cutter can work normally in high temperature environment. Ball nose milling cutters can be used in various industries. [0003] At present, a kind of integral ball end milling cutter is mostly used in the finishing of splicing molds for automobile panels. During the process of processing splicing parts, the milling processing characteristics in the splicing transition zone are complicated, and the wear and damage of the cutting tools are serious. ...
