Preparation method of milling cutter with open slots

Abstract

The invention relates to a preparation method of a milling cutter with open slots, a manufacturing process comprises: the excircle of a metal disc is cut into a plurality of sawtooth grooves in the same direction in a uniformly distributed manner so as to form a cutter body, the method is characterized in that: (1) after a plurality of open slots are made at the bottom of the sawtooth grooves in a uniformly distributed manner along the center line direction of one surface of the cutter body, oil quenching and tempering treatments are carried out on the cutter body; (2) an alloy cutter head is welded on each sawtooth groove of the cutter body along the same direction, so as to form a milling cutter; (3) a vacuum furnace heat treatment is carried out on the milling cutter manufactured in step (2). According to the preparation method, the open slots are made in one surface of the cutter body, the internal stress of the cutter body is released during cutting, the vibration of the cutter body is eliminated, the problem that the milling cutter vibrates during working is solved, the processing resistance is reduced, the abrasion of a cutting edge is lowered, the phenomena of resonance, cutter blocking and cutter hitting generated when the milling cutter works are prevented, not only are the processing precision and the cutting speed enhanced, but also the waste of raw materials caused by the rejection rate of products is reduced by a large margin.

Description

technical field [0001] The invention belongs to the technical field of cutting tools for metal materials, and in particular relates to a preparation method of a milling cutter with an open slot. Background technique [0002] In the field of metal material cutting, cutting tool technology and cutting processing technology are constantly exploring, practicing, developing and improving around the goal of high efficiency and low consumption of cutting tools. The cutting ability and effect of metal material cutting tools in the actual cutting process directly affect the quality of processed products and the pass rate of products. [0003] At present, when the known saw blade milling cutter is used for one-time cutting of workpieces made of non-ferrous metals, copper or stainless steel, no matter whether it is down milling or up milling, the tool is affected by cutting resistance during the cutting process. At the same time, the fit between the shape of the blade and the surface ...

Problems solved by technology

[0003] At present, when the known saw blade milling cutter is used for one-time cutting of workpieces made of non-ferrous metals, copper or stainless steel, no matter whether it is down milling or up milling, the tool is affected by cutting resistance during the cutting process. At the same time, the fit between the shape of the blade and the surface contour of the workpiece is insufficient, so that the force on the cutter body at the cutting point is uneven, resulting in machining resistance caused by vibration of the cutter body, blade wear, machining resonance, knife jamming and knife hitting. It affects the processing accuracy of the product, reduces the cutting speed, and increases the reject rate of the product, resulting in waste of raw materials
