Integral double-end forming slot milling cutter for stainless steel machining

Abstract

The invention provides an integral double-end forming slot milling cutter for stainless steel machining, which is suitable for machining forming slots of typical difficult-to-machine materials and capable of reducing the use amount of cutters, improving the cutting efficiency, prolonging the service life of the cutters, and reducing the cutter replacement and storage costs. The integral double-endforming slot milling cutter comprises a cutter bar, wherein a rough milling blade part is arranged at one end of the cutter bar in the length direction; a finish milling blade part is arranged at theother end of the cutter bar in the length direction; the blade starting end of the rough milling blade part is of a flared trapezoidal structure; the blade starting end of the finish milling blade part is of a flared trapezoidal structure; the number of the annularly-distributed cutting edges of the rough milling blade part is smaller than that of the annularly-distributed cutting edges of the finish milling blade part; and the milling cutter is made of solid carbide.

Description

technical field [0001] The invention relates to the technical field of milling cutter structures, in particular to an integral double-headed groove milling cutter for machining stainless steel. Background technique [0002] Stainless steel, titanium alloys and high-temperature alloys are typical difficult-to-machine materials. They are widely used in aerospace, automobile manufacturing, and medical equipment due to their good mechanical properties such as high thermal strength, good corrosion resistance, and strong heat resistance. However, due to its poor thermal conductivity, small elastic modulus, and plastic deformation, its cutting force is generally large, and its strong chemical activity makes it easy to chemically react with tool materials. Work hardening and high cutting temperature lead to serious tool wear and low processing efficiency. [0003] As a multi-edged tool, the milling cutter has a high production efficiency due to the large number of teeth participatin...

AI Technical Summary

Problems solved by technology

[0004] Existing general-purpose milling cutters are processed with a single head, and the replacement of the cutter is more frequent after the cutter fails and wears, resulting in a serious waste of cutter material costs; at the same time, due to the single specification of the same type of cutter, the use of multi-specification cutters leads to an increase in storage costs; in addition, for specific molding contour sizes For processing, it is often necessary to use multiple milling cutters to process alternately, especially for forming processing of difficult-to-machine materials. It leads to deviations in the processing size and accuracy of the workpiece, and it takes time to change the tool and the production efficiency is low.
