Abstract

The utility model provides a high-temperature alloy fine machining integrated alloy end mill which comprises a handle part and a blade part, wherein a side blade front angle on the blade part is 6-8 degrees, a side blade rear angle is 11-13 degrees and a helical angle is 38-40 degrees; and preferably, the side blade front angle on the blade part is 7 degrees, the side blade rear angle is 12 degrees, and the helical angle is 39 degrees. Because the side face spiral cutting blade front angle and rear angle are increased, the cutting edge is sharpened, the cutting resistance is reduced, and the cutting wear is reduced; and therefore, the cutting performance of the fine machining ZG35Cr24Ni7SiN high-temperature alloy integrated hard alloy numerical control end mill is improved, the machining removal rate is correspondingly improved, and the service life of the integrated hard alloy numerical control end mill is prolonged.

Description

High temperature alloy fine finishining Integral alloy slotting cutter
Technical field
The utility model relates to a kind of high temperature alloy fine finishining Integral alloy slotting cutter, is used for the fine finishining of ZG35Cr24Ni7SiN high temperature alloy.
Background technology
The ZG35Cr24Ni7SiN high temperature alloy has the advantages such as intensity height, high-temperature behavior be good, thereby, be used in more and more widely in the Aero-Space manufacturing industry.But the ZG35Cr24Ni7SiN high temperature alloy is a kind of material of difficult machining, and its main cause is that yield strength is high, poor thermal conductivity, so the cutting ability of material is poor, and is larger to the wearing and tearing of cutter, so that tool wear is more serious.
Existing fine finishining ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill is because main structure parameters side spiral cutting angle of cutting edge and relief angle are less, it is 0 °~3 ° such as anterior angle numerical value, relief angle numerical value is 8 °~10 °, so that cutting edge is not sharp, cutting resistance is large, but also has aggravated the wearing and tearing of cutter.In addition because the centripetal angle of end cutting edge is less, therefore finally caused existing processing ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill cutting ability poor, the fine finishining clearance is low, generally at 1~2cm3/min, cutting at one time is short process time, be generally 30~40min, therefore be difficult to satisfy the finishing requirements of ZG35Cr24Ni7SiN high temperature alloy part.
Summary of the invention,
The purpose of this utility model provides a kind of fine finishining ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill that improves cutting ability and working (machining) efficiency.
The technical solution of the utility model: high temperature alloy fine finishining Integral alloy slotting cutter, comprise shank and blade, the side edge anterior angle on the blade is 6 °~8 °, and the side edge relief angle is 11 °~13 °, and helical angle is 38 °~40 °.
Preferably, the side edge anterior angle on the blade is 7 °, and the side edge relief angle is 12 °, and helical angle is 39 °.
The cutting clearance of high temperature alloy fine finishining Integral alloy slotting cutter is not less than 5cm3/min, and disposable machining time lengthening is to 90min.
The beneficial effects of the utility model: because side spiral cutting angle of cutting edge and relief angle are increased, can be so that cutting edge becomes sharp, cutting resistance reduces, wearing and tearing reduce to cutting edge, therefore improved the cutting ability of fine finishining ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill, also improve accordingly the machining clearance, prolonged the service life of solid carbide numerical control end mill; The utility model is 7 ° with the side edge anterior angle that end mill structure is designed on the blade, and the side edge relief angle is 12 °, and helical angle is 39 °, so that the performance of whole cutter reaches optimization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, this embodiment is that diameter is that 20mm, cutting edge length are the high temperature alloy fine finishining Integral alloy slotting cutter of 38mm, comprises shank 2 and blade 1, and the side edge anterior angle 4 on the blade 1 is 6 °~8 °, side edge relief angle 5 is 11 °~13 °, and helical angle 3 is 38 °~40 °.Preferably, the side edge anterior angle 4 on the blade 1 is 7 °, and side edge relief angle 5 is 12 °, and helical angle 3 is 39 °.
Adopt the above-mentioned parameter design so that cutting edge becomes sharp, cutting resistance reduces, prolonged the cutting edge working durability, therefore improved the cutting ability of fine finishining ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill, also improved accordingly the machining clearance, prolong the service life of solid carbide numerical control end mill, satisfied the accurately machined requirement of the high-quality and efficient milling of ZG35Cr24Ni7SiN high temperature alloy.
