Purpose of utility model: for above-mentioned existing problem and shortage in the prior art, the purpose of this utility model is
A kind of left-handed left cut forming reamer for processing martensitic stain less steel inner hole is provided.
Technical solution: in order to achieve the above objectives, a kind of left side processing martensitic stain less steel inner hole described in the utility model
Left cut forming reamer is revolved, including blade and shank, the blade include butt cutting edges, bottom hole deburring sword, hole bottom chamfer one, hole
Bottom chamfer two, inner hole side edge, orifice chamfer and left-handed chip space, the quantity of the butt cutting edges are six, and equidistant circumferential direction is set
It sets in the front end of blade, bottom hole deburring sword is arranged between butt cutting edges and hole bottom chamfer one, and the hole bottom chamfer two is set
It sets between hole bottom chamfer one and inner hole side edge, the orifice chamfer is arranged on rear side of inner hole side edge, on rear side of the butt cutting edges
Equipped with knife spine, left-handed chip space is equipped between adjacent knife spine.
Further, the knife spine is equipped with double seamed edges and ladder sword, double seamed edges extend to ladder from butt cutting edges
At sword.The design of double seamed edges, when facilitating tool sharpening, keep with the gap on hole machined surface, facilitate control friction and by
Rub the heat generated, reduces the generation of heat, is conducive to drilling and stablizes, increases the intensity of cutter.
Further, be equipped among the blade and shank blade transition angle, blade transition angle and horizontal line institute at
Angle is 45 °；And the diameter of the blade tail portion is greater than the diameter of shank.
Further, it is solid that side is additionally provided on the shank.It, can be in the biggish workpiece of cutting hardness in such a way that side is solid
When, it can be avoided cutter and beat, guarantee the stability in use process.
Further, the bottom hole deburring sword and horizontal line angle are 10 ° ~ 12 °, the hole bottom chamfer one and water
Horizontal line angle is 20 ° ~ 22 °, and the hole bottom chamfer two is 45 ° with horizontal line angle, the inner hole side edge and level
Line is parallel, and the orifice chamfer and horizontal line angle are 90 °.
Further, the left-handed chip space becomes narrow gradually from blade end to blade middle position.
Above-mentioned technical proposal can be seen that the utility model has the following beneficial effects:
It is described in the utility model it is a kind of process martensitic stain less steel inner hole left-handed left cut forming reamer, collect hole at
Type, orifice chamfer, aperture deburring and reversed chamfering etc. are multi-functional in one；By the design method of 6 sword butt cutting edges, reduce
The cutting resistance of each sword improves the stock-removing efficiency of each sword, while can guarantee that all compact dimensions settle at one go, improves
Stock-removing efficiency, is greatly saved the cost of charp tool；Pass through the design of the left-handed left cut of the left-handed chip space and end sword cutting edge of blade
And increase the solid design method in side, it solves the problems, such as cutter chatter mark, improves the service life of cutter.
