Abstract
The invention discloses a circular groove machining cutter and a machining method of a blade of the circular groove machining cutter. The circular groove machining cutter comprises a cutter body and the blade; the cutter body comprises a cutter body handle and a positioning part, the positioning part is used for installing the blade and corresponds to a circular groove of a to-be-machined workpiece (5), the cutter body is provided with a blade installing groove penetrating the positioning part and extending to the cutter body handle from outside to inside in the axial direction, the blade installing groove divides the positioning part to form an installing part and a compression part, and a chip removal notch is formed above the installing part; and the blade is arranged in the blade installing groove, and the compression part is provided with a positioning compression piece used for positioning and compressing the blade. When applied, the circular groove machining cutter can be used on a lathe, a milling machine or a boring mill, the circular groove is machined by clamping the cutter one time, other finish machining processes do not need to be additionally carried out, and the production efficiency of product parts can be obviously improved; and in addition, the cutter is clamped through the installing part and the compression part, sufficient strength and rigidity are guaranteed, a blade part is free of vibration in the machining process, and the surface roughness of machining piece product parts is improved.
Description
technical field [0001] The present invention relates to the field of machining equipment for mechanical parts, and more specifically, relates to a tool for machining an annular groove, and also relates to a method for machining blades of the tool for machining an annular groove. Background technique [0002] Among some mechanical product parts, there is a class of product parts made of stainless steel. The grade of stainless steel is 0Cr17Ni4Cu4Nb, and its heat treatment hardness value is 33-38HRC. The product parts are provided with relatively deep annular grooves. The depth and width of the annular groove The ratio is about 3.5, the size tolerance or position tolerance is generally not more than 0.02 ~ 0.03mm, and the roughness is Ra0.8. When the width of this type of annular groove is less than 5mm (the width of the annular groove of this product part is 4.3mm), and the depth of the annular groove is relatively large (for example, greater than 10mm), that is, when the rat...
