Abstract
The invention discloses a mechanically-clamped and indexable helical vertical milling blade for finish machining, wherein cutting tools of the mechanically-clamped and indexable helical vertical milling blade for finish machining have a certain radian; preferably, the cutting tools are arc-shaped. The mechanically-clamped and indexable helical vertical milling blade for finish machining has the advantages as follows: 1, the arc tools can reduce and eliminate radial difference due to inclination angles of the cutting tools, so that machining lines of a machined surface are reduced; 2, the surface smoothness of the machined surface of a workpiece is improved, with the roughness value Ra of 1.6 microns; 3, the blade is mechanically-clamped and indexable and can have multiple cutting tools, so that the blade and the cutting tools thereof can be conveniently replaced.
Description
Technical field
The present invention relates to machine clip variable-position helical end mills sheet for a kind of fine finishining.
Background technology
The blade of using on indexable helical end mill (being commonly called as maize milling cutter) is at present no matter be blade and the parallelogram blade of AP type, and cutting edge is straight flange.
The cutting edge inclination λ of cutting edge
sbe less than the helixangleβ of cutter tooth chip area.Because cutting edge is straight line, therefore the last point of cutting edge is not on same cylinder.Suppose that the mid point C of cutting edge is on the nominal diameter d(face of cylinder of milling cutter) upper, and on blade cut sword, radial position A, the B point of each point is all ordered than C greatly.The radially potential difference that blade wedge angle A, B are 2 is maximum.From Figure of description 1, can obtain
From above formula: blade is longer, and cutting edge inclination is larger, and milling cutter diameter is less is that radially potential difference is larger, well imagines that the roughness value of finished surface is larger.So generally make λ
s< β, and go steadily favourable to chip removal and working angles of larger β.Basic reason is: because cutting edge point is not on the same face of cylinder, cut radially that potential difference is larger, so just with and roughing.
Summary of the invention
The present invention has designed and developed machine clip variable-position helical end mills sheet for a kind of fine finishining, with the radial difference that reduces to cause because of cutting edge inclination, thereby can complete the fine finishining to surface of the work, further improves the fineness of machined surface.
Technical scheme provided by the invention is:
A machine clip variable-position helical end mills sheet for fine finishining, wherein, the cutting edge of described blade has certain radian.
Preferably, described cutting edge is Circular Nose Cutting Edge.
Preferably, described blade is square-shaped, and its center offers screw hole.
Preferably, described blade has rounding.
Preferably, described blade has anterior angle, and the number of degrees scope of described anterior angle is spent in 10 degree-25.
Preferably, described blade has relief angle, and the number of degrees scope of described relief angle is spent in 5 degree-20.
Fine finishining provided by the invention with machine clip variable-position helical end mills sheet by cleverly cutting edge being designed to Circular Nose Cutting Edge and having anterior angle.Such benefit is: first Circular Nose Cutting Edge can reduce and eliminate the radial difference causing because of cutting edge inclination, thereby has reduced the processing lines of machined surface; It two is the surface smoothnesses that improve workpiece machined surface, and roughness value can reach Ra=1.6um; Its three be blade adopt be can machine clip variable-position mode, can have a plurality of cutting edges, facilitate the replacing of blade, and the replacing of blade cut sword.
Accompanying drawing explanation
Fig. 1 is the use schematic diagram of the helical end mills blade of prior art;
Fig. 2 is the top view of machine clip variable-position helical end mills sheet for fine finishining of the present invention;
Fig. 3 is the front view of machine clip variable-position helical end mills sheet for fine finishining of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As Figure 2-3, the invention provides machine clip variable-position helical end mills sheet 1 for a kind of fine finishining, wherein, the cutting edge 2 of described blade has certain radian.Preferably, described cutting edge is Circular Nose Cutting Edge.
Preferably, described blade is square-shaped, and its center offers screw hole 3.
Preferably, described blade has rounding 4.
Preferably, described blade has anterior angle 5, and the number of degrees scope of described anterior angle is spent in 10 degree-25.
Preferably, described blade has relief angle 6, and the number of degrees scope of described relief angle is spent in 5 degree-20.
Fine finishining provided by the invention with machine clip variable-position helical end mills sheet by cleverly cutting edge being designed to Circular Nose Cutting Edge and having anterior angle.Such benefit is: first Circular Nose Cutting Edge can reduce and eliminate the radial difference causing because of cutting edge inclination, thereby has reduced the processing lines of machined surface; It two is the surface smoothnesses that improve workpiece machined surface, and roughness value can reach Ra=1.6um; Its three be blade adopt be can machine clip variable-position mode, can have a plurality of cutting edges, facilitate the replacing of blade, and the replacing of blade cut sword.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in description and embodiment, it can be applied to various applicable the field of the invention completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend of describing.
