Abstract
The utility model discloses an efficient twin-core diameter unequal rough machining milling cutter, comprising a shank part, wherein one end of the shank part is provided with a cutting edge part, the cutting edge part comprises a first cutting edge, a second cutting edge, a third cutting edge and a fourth cutting edge, a first cutting edge included angle and a third cutting edge included angle are the same, a second cutting edge included angle and a fourth cutting edge included angle are the same, the first cutting edge included angle and the second cutting edge included angle are complemented with each other, the front angles and the rear angels of the four cutting edges are the same, four helical angles are the same, and a first cutting edge core diameter and a second cutting edge core diameter are not the same.. The efficient twin-core diameter unequal rough machining milling cutter adopts a twin-core diameter geometric structure, so the cutting space is ensured, and the torque and load of the cutter are reduced, and the rigidity of the cutter is also increased. An unequal groove type design is adopted, so the cutting resonance phenomenon which is produced when metal is cut and roughly machined is effectively controlled, the cutting is enabled to be stable, so when the metal cutting and machining are finished, the cutting operation can be completed at a higher rotational speed and larger feed compared with those of the like products.
Description
Technical field
The utility model relates to a kind of cutter of mechanical manufacturing field, does not wait in particular to a kind of high efficiency twin-core footpath and cuts apart heavy-duty cutter.
Background technology
Slotting cutter is mainly used in high-speed numeric control CNC lathe in the production roughing of high-accuracy spare and accessory parts such as processing IT, mould, medicine equipment, Aero-Space, military equipment.
The slotting cutter of prior art is 4 grooves; The design of each groove core diameter for equating; Reduced to hold and cut the space and be unfavorable for that row cuts, the load when increasing Tool in Cutting, identical helicla flute spacing (or tooth pitch); Therefore in the cutting metal process, be easy to generate resonance, influence the surface quality of production efficiency and processing back workpiece and can reduce cutter life etc.
The utility model content
The purpose of the utility model is to overcome the above problem that prior art exists, and provides a kind of high efficiency twin-core footpath not wait and cuts apart heavy-duty cutter.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
High efficiency twin-core footpath is not waited and is cut apart heavy-duty cutter; Comprise shank portion, said shank portion one end is provided with knife edge part, and said knife edge part comprises first blade, second blade, the 3rd blade and four blade sword; First knife edge included angle, the 3rd knife edge included angle equate; Second knife edge included angle, four blade sword angle equate that said first knife edge included angle and said second knife edge included angle are complementary, and four blade anterior angles and four circumferential clearances equate; Four helical angles equate that the first blade core diameter and the second blade core diameter are unequal.
Further, said blade anterior angle is 3 degree.
Further, said circumferential clearance is 6 degree.
Further, said helical angle is 35 degree.
Further, the said first blade core diameter is 0.5 times of blade diameter.
Further, the said second blade core diameter is 0.69 times of blade diameter.
The beneficial effect of the utility model is:
The utility model adopts the geometry in twin-core footpath not only to guarantee to hold the rigidity that the space of cutting has reduced cutter torque power and load but also increased cutter.Adopt and do not wait the design of cutting apart grooved.The cutting covibration that has produced when effectively having suppressed metal cutting roughing makes and stable cutting has improved the metal resection rate simultaneously again.So adding man-hour in the completion metal cutting can be than like product with higher rotating speed, the higher efficient of bigger feeding is accomplished cutwork.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
