example 1

[0039] The number of teeth of the milling cutter is Z=16, the helix angle β=25°, the average diameter of the milling cutter to be processed is D=142.94, and the shoveling amount of the cutter tooth is K=6. The rear wave edge moves to the right, the pitch S=8, the bottom R of the rear wave edge is R1.8, the R of the tooth top is R2.5, and the rear wave edges of adjacent teeth are staggered by 0.5mm along the milling cutter axis.

[0040] Steps:

[0041]1. Make a template according to the profile of the milling cutter to be processed, and install it on the corresponding part of the gear removal machine tool.

[0042] 2. Dressing the grinding wheel profile of the shoveling machine tool.

[0043] The forklift tool is made according to the tooth shape of the rear wave blade, in which the top R of the turning tool is the bottom R of the rear wave blade tooth 底 , both sides of the top R are smoothly transferred to half of the rear wave edge addendum R 顶 And it is tangent to the fi...

example 2

[0059] The number of teeth of the milling cutter is Z=16, the helix angle β=25°, the average diameter of the milling cutter to be processed is D=132.60, and the shoveling amount of the cutter tooth is K=6. The rear wave edge moves to the right, the pitch S=8, the bottom R of the rear wave edge is R1.8, the R of the tooth top is R2.5, and the rear wave edges of adjacent teeth are staggered by 0.5mm along the milling cutter axis.

[0060] Steps:

[0061] Change the differential hanging gear of the shovel gear machine to I 2 =55×60 / 62×39, and the rest of the operation steps are the same as Example 1.

example 3

[0063] The number of teeth of the milling cutter is Z=16, the helix angle β=25°, the average diameter of the milling cutter to be processed is D=146.02, and the shoveling amount of the cutter tooth is K=6.2. The rear wave edge moves to the right, the pitch S=8, the bottom R of the rear wave edge is R1.8, the R of the tooth top is R2.5, and the rear wave edges of adjacent teeth are staggered by 0.5mm along the milling cutter axis.

[0064] Steps:

[0065] Change the differential hanging gear of the shovel gear machine to I 2 =50×58 / 60×39, the actual K value is changed to: K 实际 = 6.2. The rest of the operation steps are the same as Example 1.

Abstract

A method for machining the waved back cutting edge of the milling cutter used to machine spirally slotted surface on workpiece includes such steps as installing a copying plate, trimming the machining surface of abrasive disc, arranging change gear, clamping the workpiece to be machined, aligning cutter, and grinding.

Description

technical field [0001] The invention belongs to the cutting tool manufacturing technology and relates to the improvement of the processing method of the rear wave edge type face milling cutter. Background technique [0002] When processing parts with large surfaces, if a milling cutter with a common shape is used for processing, since the contact area between the milling cutter and the processed part is too large, a large cutting resistance will be generated during the processing, and the vibration caused by this resistance cannot guarantee the quality of the parts. machining accuracy. This abnormal processing process is also easy to cause the fragmentation of the milling cutter, and even the cutting process cannot be performed. Therefore, when processing parts with large faces or difficult-to-machine materials, rear wave edge face milling cutters are often used. At this time, because the contact area between the milling cutter and the processed part is reduced, the cuttin...
