Abstract
The utility model provides a high-temperature alloy rough 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 5-7 degrees, a helical angle is 34-36 degrees, and the circular arc radius of the cutting edge is 0.02-0.04mm; and preferably, the side blade front angle on the blade part is 6 degrees, the helical angle is 35 degrees, and the circular arc radius of the cutting edge is 0.03mm. According to the alloy rough machining integrated alloy end mill, the cutting removal rate is not less than 7cm<3> per minute, and the one-time cutting machining time is prolonged to 120 minutes. By adopting the structure, the strength of the cutting edge is increased, the cutting resistance is reduced, and the service life of the cutting edge is prolonged; and therefore, the cutting performance of the rough 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
Technical field
The utility model relates to a kind of high temperature alloy roughing Integral alloy slotting cutter, is used for the roughing 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 roughing 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 larger, it is 8 °～10 ° such as anterior angle numerical value, cutting edge is Passivation Treatment not, rounded cutting edge radius is 0～0.01mm, so that cutting edge strength is relatively poor, the wearing and tearing of cutter have been aggravated; Helical angle is larger, is 38 °～40 ° such as helical angle numerical value, has increased cutting resistance.Finally caused existing processing ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill, the roughing clearance is low, generally at 2～3cm3/min, cutting at one time is short process time, be generally 35～40min, therefore be difficult to satisfy the roughing requirement of ZG35Cr24Ni7SiN high temperature alloy part.
Summary of the invention,
The purpose of this utility model provides a kind of roughing 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 roughing Integral alloy slotting cutter, comprise shank and blade, the side edge anterior angle on the blade is 5 °～7 °, and helical angle is 34 °～36 °, and rounded cutting edge radius is 0.02mm～0.04mm.
Preferably, the side edge anterior angle on the blade is 6 °, and helical angle is 35 °, and rounded cutting edge radius is 0.03mm.
The cutting clearance of high temperature alloy roughing Integral alloy slotting cutter is not less than 7cm3/min, and disposable machining time lengthening is to 120min.
The beneficial effects of the utility model: because side spiral cutting angle of cutting edge and side spiral cutting sword helical angle are reduced, and rounded cutting edge radius increased, can be so that the intensity increase of cutting edge, cutting resistance reduces, prolonged the cutting edge working durability, therefore improve the cutting ability of roughing ZG35Cr24Ni7SiN high temperature alloy solid carbide numerical control end mill, also improved accordingly the machining clearance, prolonged the service life of solid carbide numerical control end mill; The utility model is 6 ° with the side edge anterior angle that end mill structure is designed on the blade, and helical angle is 35 °, and rounded cutting edge radius is 0.03mm, so that the performance of whole cutter reaches optimization.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the local enlarged diagram of Fig. 2.
The specific embodiment
As shown in Figure 1 to Figure 3, this embodiment is that diameter is that 20mm, cutting edge length are the high temperature alloy roughing Integral alloy slotting cutter of 38mm, comprises shank 2 and blade 1, and the side edge anterior angle 4 on the blade 1 is 5 °～7 °, helical angle 3 is 34 °～36 °, and rounded cutting edge radius 5 is 0.02mm～0.04mm.Preferably, the side edge anterior angle 4 on the blade 1 is 6 °, and helical angle 3 is 35 °, and rounded cutting edge radius 5 is 0.03mm.
Adopt the above-mentioned parameter design so that the intensity of cutting edge increases, cutting resistance reduces, prolonged the cutting edge working durability, therefore improved the cutting ability of roughing 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 rough machined requirement of the high-quality and efficient milling of ZG35Cr24Ni7SiN high temperature alloy.
