Abstract
The utility model relates to a special blade for a spiral rotor milling cutter. The blade has a circular arc R of the point of 2-2.5, a front cutting angle of 21-27 degrees, a cutting edge length of 0.8-1.2, a rear cutting angle of 5.5-6.5 degrees and a chip breakage groove width of 1.8-2; the circular arc of a chip breaker groove and the circular arc of the point of the blade are concentric and adopt the double-layer coating technology. The utility model can improve the rotor processing efficiency and reduce the rotor processing cost and has prolonged service life.
Description
Technical field
The present invention relates to a kind of helical rotor milling machine used a kind of special milling cutter when milling screw rotor.
Background technology
In the prior art, as shown in Figure 3 and Figure 4, it adopts diamond shaped insert, in 35 ° of blades that all cutter production firms at home and abroad produce, tool arc is 0.4,0.8,1.2 3 kind of circular arc be as standard, uses this kind blade when processing rotor, because of its tool arc is little, cutting output is little, and workpiece rotational frequency is slow, the efficient of processing rotor is very low, and this blade point of a knife length is big, and the point of forging a knife easily, chip-breaker only are suitable for the single-blade cutting, the condition that can't adapt to the cutting of milling twolip, the chip breaking poor effect.
Summary of the invention
The purpose of this utility model provides a kind of special milling cutter for helical rotor milling, by the technical program, not only can improve cutting speed, and has increased the service life of cutter, can remedy the deficiency that prior art exists.
The technical scheme that the utility model solves the problems of the technologies described above is: special milling cutter for helical rotor milling, it is characterized in that: the blade tool arc is R2～2.5,21 °～27 ° of blade cut anterior angles, cutting edge length 0.8～1.2,5.5 °～6.5 ° of relief angles, chip-breaker width 1.8～2, chip-breaker circular arc and tool arc are isocentric circular arc, adopt the duplex coating technology.
Above-mentioned duplex coating technology, ground floor are the nitrogen titanium aluminide, and the second layer is an alundum (Al;
By the blade center hole, blade is fixed on the special-purpose cutterhead during above-mentioned blade work.
The beneficial effect of the utility model special milling cutter for helical rotor milling is: 1, by the technical program, not only can improve the efficient of processing rotor, and improve the service life of blade, cut down finished cost; 2, this device need not change any structure and the numerical control program of helical rotor milling machine, and using method is identical with original technology, but result of use is obviously improved.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of the present invention.
Fig. 3 is a blade cut schematic diagram in the prior art.
Fig. 4 is the overall structure schematic diagram of blade in the prior art.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in the figure, the special milling cutter for helical rotor milling that the utility model relates to, blade point of a knife (1) circular arc is R2.5, (2) 25 ° of blade cut anterior angles, cutting edge length 1.1, (3) 6 ° of relief angles, chip-breaker (4) width 1.8, chip-breaker (4) circular arc and point of a knife (1) circular arc are isocentric circular arc, adopt the duplex coating technology, ground floor is the nitrogen titanium aluminide, and the second layer is an alundum (Al.
By the blade center hole, with screw special blade is fixed on the cutterhead, cutterhead rotates the Milling Process of carrying out rotor.
The above only is a kind of embodiment of the present utility model, is not to be used to limit protection scope of the present invention.
