Description
Technical field
The utility model relates to a kind of reamer, particularly a kind of six sword reamers.
Background technology
Reamer is a kind of in order to excise the rotary cutter of machined surface metal, hole after Milling Process can obtain size and dimension accurately, the main effect of its reamer is namely in order to improve the machining accuracy in hole, reduce its surperficial roughness, be applicable to fine finishining and semi-finished cutter, its allowance is generally very little.In practical operation, unstable due to the long-term use of lathe and main shaft power output, causes main shaft to produce and beats, and causes the reamer machining accuracy with front angle number not reach requirement.
Summary of the invention
The purpose of this utility model is to provide that a kind of machining accuracy is high, six sword reamers of long service life.
The technical scheme that realizes the utility model object is as follows:
A kind of six sword reamers, comprise handle of a knife, cutter neck and cutting portion, one end one of described cutter neck connects handle of a knife, the other end one of cutter neck connects cutting portion, the diameter of described cutter neck is less than the diameter of handle of a knife, the diameter of described cutter neck is less than the diameter of cutting portion, the end of described cutting portion is provided with six cutters tooth, on cutting portion, be also provided with six helical form cutting edges corresponding with cutter tooth, between cutting edge, be provided with helical form chip area, the helical angle of described chip area is 6 °, and described cutter tooth anterior angle is 0 °, and described cutter tooth relief angle is 8 °.
Described handle of a knife end is provided with 45 ° of chamferings.
Described cutting portion surface is provided with TiAlN coating.
After adopting said structure, the utility model six sword reamer machining accuracies are high, long service life.
