Abstract

The invention discloses a bulb end milling cutter and a milling processing four-shaft associated device thereof. An S-shape bulb edge (1) is connected with a spiral circumferential edge (5), a bulb edge front face is connected smoothly with the circumferential edge front face (6), the bulb rear face (3) is connected with the circumferential edge rear face (7), and the bulb edge spiral groove (4) is connected with the circumferential edge spiral groove (8); the front angle of the bulb edge front face (2) is a rather big positive front angle, and is distributed with a small-big-small mode from inside to outside; the milling processing four-shaft associated device of the bulb end milling cutter comprises a latch bed (10), a horizontal longitudinal X axis straight-line motion flat stage (11), a horizontal transversal Y-axis straight-line motion flat stage (12), a vertical Z axis straight-line motion flat stage (13), a workpiece rotating shaft (14), and a front tool face milling head (15), and a rear tool face milling head (16). The invented devices are provided with characteristics of stable milling, smooth chip removal, simple structure, low cost, moderate price, and economic.

Description

technical field [0001] The invention relates to a milling tool and processing equipment thereof, in particular to a ball end mill for CNC machine tool processing and four-axis linkage equipment for grinding processing thereof. Background technique [0002] Ball end mills are a new type of tool commonly used in CNC machine tools for machining complex surfaces. They are widely used in mold manufacturing, automobile manufacturing, aerospace, electronic communication product manufacturing and other industries. [0003] The rake face of the integral ball end mill seen at present is generally formed by grinding with simple grinding equipment below the four-axis linkage. The ball edge is a plane cutting edge, and the ball edge rake face is a negative rake angle. Or part of the negative rake angle, and the rake face of the ball edge (that is, the cutting edge of the ball head) and the peripheral edge (that is, the cutting edge of the circumference part, the circumference part of the...
