Abstract
The invention discloses a three-edge flat bottomed milling cutter for plastics. The three-edge flat bottomed milling cutter comprises a cylindrical tool shank, a tool bit is formed on the tool shank, three groups of spiral edges are formed in the tool bit and comprise a main cutting edge and an auxiliary cutting edge, a spiral cutting groove is formed between two adjacent main cutting edges, a V-shaped groove tail is formed in the rear end of the cutting groove, and an included angle beta between the auxiliary cutting edge at the groove tail end and the horizontal line is 45 degrees; an inclined end edge is formed in the front end of the tool bit, an included angle gamma between the end surface of the end edge and a radial cross section of the tool bit is 0.1 degree, and a circular arc-shaped groove is formed in a front side edge of the end edge. The three-edge flat bottomed milling cutter adopts three edges of the milling cutter, so that a wider cutting groove and a chip groove tail angle are provided, meanwhile, the groove is designed in the end edge to facilitate chip removal, and plastics can be cut and removed at a higher feed speed.
Description
Technical field:
The present invention relates to the technical field of milling cutter, more specifically to the flat milling cutter of three swords for plastics.
Background technology:
Milling cutter, for Milling Process, have the rotary cutter of one or more cutters tooth.It is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine.And flat milling cutter is the milling cutter of a kind of conventional processing plane and side, the blade of existing flat milling cutter generally has two-edged, four swords and six swords, it take even number sword as main, it mainly processes the metals such as iron, aluminium and plastics etc. nonmetal is main, and when processing plastic goods, its plastic material is softer, cutter not easy to wear and fracture, so can use higher feed speed when roughing, and its smear metal is also once many after speed quickening, and the flat milling cutter of general standard its chip removal effect when cutting plastic is less desirable now.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and the flat milling cutter of three swords for plastics is provided, and it can effectively guarantee the eliminating of smear metal when High-speed machining plastic material.
For achieving the above object, the flat milling cutter of three swords for plastics of the present invention, comprise columniform handle of a knife, on handle of a knife, form cutter head, on cutter head, have spiral helicine three groups of blades, described blade comprises main cutting edge and front cutting edge, forms the chip trough of spiral between two adjacent main cutting edges, chip trough rear end type has the groove tail of V-type, and the front cutting edge of groove tail end and the angle β between horizontal line are 45 °; The front end of described cutter head forms skewed end sword, and the angle γ between end sword place end face and cutter head radial cross-section is 0.1 °, forms the groove of circular arc on the front side edge of described end sword.
As technique scheme preferably, the cross section of described end sword is trapezoidal, the groove of end sword is at the rear side of end angle of throat point.
Beneficial effect of the present invention is: it adopts three swords as the blade number of milling cutter, makes it have wider cutting slot and chip area caudal horn degree, designs groove again simultaneously and is convenient to chip removal, thereby can guarantee under higher feed speed, plastics cutting to be got rid of on end sword.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that enlarged drawing is looked on the right side at cutter head of the present invention place 2.
Symbol description in figure:
1, handle of a knife; 2, cutter head; 3, main cutting edge; 4, front cutting edge; 5, chip trough; 6, end sword; 7, groove.
The specific embodiment:
See shown in Fig. 1 and Fig. 2: the flat milling cutter of three swords for plastics of the present invention, comprise columniform handle of a knife 1, on handle of a knife 1, form cutter head 2, spiral helicine three groups of blades on cutter head 2, described blade comprises main cutting edge 3 and front cutting edge 4, between two adjacent main cutting edges 3, form the chip trough 5 of spiral, chip trough 5 rear end types have the groove tail of V-type, and front cutting edge 4 and the angle β between horizontal line of groove tail end are 45 °; The front end of described cutter head 2 forms skewed end sword 6, and the angle γ between end sword 6 place end faces and cutter head 2 radial cross-sections is 0.1 °, forms the groove 7 of circular arc on the front side edge of described end sword 6.
The cross section of end sword 6 is trapezoidal, and the groove 7 of end sword 6 is at the rear side of end sword 6 points of a knife.
Operation principle: the present invention adopts three swords as the blade number of its flat milling cutter, compare the flat milling cutter of two-edged and there is the operation stability of reinforcement, the flat milling cutter difference of stability and four swords less than, but there is larger cutting slot than the flat milling cutter of four swords, it has specially for plastics cutting has been provided with cutting slot spiral angle, and simultaneously on end sword, design groove again and be convenient to chip removal, thereby can guarantee under higher feed speed, plastics cutting to be got rid of.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
