Problems solved by technology

In this way, there is a certain gap between the measured profile on the rake face and the theoretical profile, and the usual machining and measurement methods for shoveling milling cutters cannot meet the needs, and this tool is manufactured for the first time in China, and there is no technical information can learn from

Embodiment Construction

[0015] refer to figure 1 , figure 2 , image 3 , Figure 4: The molded line on the cutting edge of the tool is processed by circular grinding on the shovel bed before the back angle of the tool is generated, and the radial line is made through the center of the tool. The molded lines of each section should be completely consistent, and a mandrel 1 is designed And model 2, model frame 3, model 2 moves horizontally on the model frame 3, and the model frame 3 makes a rotary motion around the center of the mandrel. At this time, the flank has no relief angle, and the profile line on the flank is the theoretical type. According to the projection principle, the profile line on the flank is consistent with the profile line on the cutting edge of the tool 4, and the profile line accuracy on the cutting edge of the tool 4 can be controlled by measuring the profile line of the flank surface.

[0016] Its specific method steps are as follows:

[0017] Both the headstock and the tailst...

Abstract

A method for detecting the profilt of blade root milling cutter is disclosed. The profile of the cutting edge on cutter is machined by circular grinding befor the back angle of said cutter is generated. A mandrel, template, and template holder are designed. Said template moves horizontally on tis holder rotating around the mandrel. At this time, the profile on the back surface of cutter is ideal and is the same as that of cutting edge, so measuring the profile of back surface of cutter can control the precision of the profile on cutting edge.

Description

technical field [0001] The invention belongs to the manufacture of disk-type wire milling cutters, in particular to a method for processing and detecting the profile of large-diameter blade fork-type blade root fine milling cutters. Background technique [0002] The "851" blade fork-shaped root milling cutter produced by the original applicant has a diameter of ∮380mm and is a shovel tooth milling cutter with a zero-degree rake angle. The cutter profile formed by the rake face is the theoretical profile of the drawing. During processing, as long as the template designed according to the theoretical profile of the drawing is pasted on the rake face, it can be easily detected. The diameter of the 40-inch blade fork-type blade root milling cutter is ∮490mm. In order to improve the processing quality, the cutter is designed as an insert cutter with a 15° rake angle, and the cutting edge shape line also has a certain angle, 45° cutting The radial dimension of the intersection fo...
