Abstract

The utility model discloses a kind of two S sword ball end mill, comprise handle of a knife (1) and cutter head (2), described cutter head (2) is provided with two groups of symmetrical helical form blades, run through between blade and have helical flute (3), described blade is by being that hemispheric main cutting edge (5) and front cutting edge (4) connect and compose, and described main cutting edge (5) is in the S-shaped distribution in point of a knife place.Tool bit part is designed to two cutting edge by the utility model, enhance the bulk strength of cutting edge, and main cutting edge is in the S-shaped distribution in point of a knife place, be equivalent to strengthen the helical angle near centre of sphere part cutting edge, actual cutting anterior angle and the length of cut increasing cutter main cutting edge, reduce cutting resistance, reduce cutting edge wearing and tearing, improve cutter life and crudy.

Description

A kind of two S sword ball end mill
Technical field
The utility model relates to a kind of two S sword ball end mill, belongs to machining tool technical field.
Background technology
Rose cutter is for milling sphere, and its main agency part is cutter hub front portion is knife head ball, therefore requires higher to the cutting edge on knife head ball, needs more mellow and fuller stable cutting edge to ensure stable working, also need stronger cutting power.But existing rose cutter, bulb part cutting edge is single S blade type face, and cutting edge is relatively thin, and intensity is lower, and is almost straight line near centre of sphere part two-edged connection cutting edge, and cause cutting resistance comparatively large, cutting edge wearing and tearing are very fast.
Utility model content
The purpose of this utility model is, provides that a kind of edge strength is better, cutting resistance is little, and cutting edge nonabradable pair of S sword ball end mill, to overcome prior art deficiency.
The technical solution of the utility model: a kind of two S sword ball end mill, comprise handle of a knife and cutter head, described cutter head is provided with two groups of symmetrical helical form blades, run through between blade and have helical flute, described blade is by being that hemispheric main cutting edge and front cutting edge connect and compose, and described main cutting edge is in the S-shaped distribution in point of a knife place;
The two section large arcs of described main cutting edge by outside and two sections of little arcs near point of a knife connect and compose;
The radius of described large arc is 1.2 × D, and the radius of described little arc is 0.35 × D, and little arc is positioned at the scope of point of a knife place 0.3 × D, and wherein D is the diameter of cutter head;
The angle α of described front cutting edge and axial line is 36 ° ~ 40 °.
Owing to adopting technique scheme, the utility model has the advantage of: tool bit part is designed to two cutting edge by the utility model, enhance the bulk strength of cutting edge, and main cutting edge is in the S-shaped distribution in point of a knife place, be equivalent to strengthen the helical angle near centre of sphere part cutting edge, actual cutting anterior angle and the length of cut increasing cutter main cutting edge, reduces cutting resistance, reduce cutting edge wearing and tearing, improve cutter life and crudy.

Fig. 2 is the left view of Fig. 1.
Description of reference numerals: 1-handle of a knife, 2-cutter head, 3-chip area, 4-front cutting edge, 5-main cutting edge, the large arc of 6-, the little arc of 7-.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
See Fig. 1 and Fig. 2, the two S sword ball end mill of one of the present utility model, comprise handle of a knife 1 and cutter head 2, the diameter of described cutter head 2 is 8mm, cutter head 2 is provided with two groups of symmetrical helical form blades, run through between blade and have helical flute 3, described blade is by being that hemispheric main cutting edge 5 and front cutting edge 4 connect and compose, and described main cutting edge 5 is in the S-shaped distribution in point of a knife place.The two section large arcs 6 of described main cutting edge 5 by outside and the two sections little arcs 7 near point of a knife connect and compose.The radius of described large arc 6 is 9.6mm, and the radius of described little arc 7 is 2.8mm, and little arc 7 is positioned at the scope of point of a knife place 2.4mm.Described front cutting edge 4 is 36 ° with the angle α of axial line.
