Summary of the invention:
Object of the present invention is exactly propose improvement project for the problem that end tooth intensity is not enough, service life is low that existing slotting cutter exists, the indexable helical end mill of Curve guide impeller increases interchangeable termination and clamping screw, all teeth cutter blades and end tooth blade adopt different square blades, Tool in Cutting is sharp, brisk, Numerical-control Milling Machines can use, and effectively improves cutter life.
Technology solution of the present invention is as follows:
A kind of indexable helical end mill, is made up of interchangeable termination, end cap clamping screw, cutter hub, end tooth blade, all teeth cutter blades, pushing broach screw.Cutter hub afterbody is 7:24 taper shank, tail end face opens screwed hole, there are six right hand helix cutting teeths cutter hub front end, every bar cutting teeth is evenly equipped with four all teeth cutter blades, all teeth cutter blades are fixed on the spiral cutting tooth of cutter hub by pushing broach screw, interchangeable termination there are six right hand helix cutting teeths, its curl is consistent with the spiral cutting tooth spiral degree of cutter hub, every bar cutting teeth is evenly equipped with two end tooth blades, end tooth blade is fixed on the spiral cutting tooth of interchangeable termination by pushing broach screw, interchangeable termination is by convex key and cutter hub groove is stuck positions, with end cap clamping screw, interchangeable termination is fixed on cutter hub front end face.
Preferred as technique scheme, all teeth cutter blades are SPHW1204 standard side's blade with holes, all teeth cutter blade relief angles 11 °.
Preferred as technique scheme, end tooth blade is XPHW1504 standard side's blade with holes, end tooth blade relief 11 °.
Preferred as technique scheme, end tooth blade overhang height 0.5mm.
Preferred as technique scheme, pushing broach screw hole center is eccentric 0.15 ~ 0.3mm inwardly.
Preferred as technique scheme, the helical angle of cutter hub and interchangeable termination is 40 °.
Beneficial effect of the present invention is: interchangeable termination and cutter hub are bolted, if the breaks down of termination can facilitate and changes in time like this, thus improve cutting-tool's used life, cutter is applicable to the roughing of jumbo machining large forging, foundry goods, and working (machining) efficiency is high.

Detailed description of the invention:
Embodiment: by particular specific embodiment, working of an invention mode is described below, those skilled in the art can understand other advantages of the present invention and effect easily by content disclosed in the present specification.
As shown in Figure 1 and Figure 2, indexable helical end mill is made up of interchangeable termination 1, cutter hub 2, end tooth blade 3, pushing broach screw 4, all teeth cutter blades 5, end cap clamping screw 6.Cutter hub 2 afterbody is 7:24 taper shank, be connected with machine tool fixture endoporus and coordinate, cutter hub 2 tail end face opens M24 screwed hole for placing bolt cutter is fixed on machine tool, there are six right hand helix cutting teeths cutter hub 2 front end, every bar cutting teeth is evenly equipped with four all teeth cutter blades 5, all teeth cutter blades 5 are fixed on the spiral cutting tooth of cutter hub 2 by pushing broach screw 4, and all teeth cutter blades 5 adopt tangential installation, blade compression strength is high, the great section workpiece that machinable material is harder; Interchangeable termination 1 there are six right hand helix cutting teeths, its curl is consistent with the spiral cutting tooth spiral degree of cutter hub 2, every bar cutting teeth is evenly equipped with two end tooth blades 3, end tooth blade 3 is fixed on the spiral cutting tooth of interchangeable termination 1 by pushing broach screw 4, end tooth blade 3 adopts tangential installation, interchangeable termination 1 is by convex key and cutter hub groove 201 is stuck positions, and with end cap clamping screw 6, interchangeable termination 1 is fixed on cutter hub 2 front end face.
As shown in Figure 3, all teeth cutter blades 5 are SPHW1204 standard side's blade with holes, thickness 4.76mm, week, angle of back of tooth E was 11 °, for indexable helical end mill, the relief angle of 11 ° can make that blade abrasion degree is minimum and the amount of feeding is maximum, and all teeth cutter blades 5 are fixed on cutter hub 2 spiral cutting tooth by M5 screw.
As shown in Figure 4, end tooth blade 3 is XPHW1504 standard side's blade with holes, thickness 4.76mm, end tooth relief angle F is 11 °, for indexable helical end mill, the relief angle of 11 ° can make that blade abrasion degree is minimum and the amount of feeding is maximum, and end tooth blade 3 is fixed on interchangeable termination 1 spiral cutting tooth by M5 screw.
