The front end for having shank section, the shank section is provided with knife neck, and the front end of knife neck is provided with blade part, and the blade part is provided with spiral shell
Rotation is provided with chip area between side edge, and adjoining spiral side edge, the front end of the reamer body is provided with fluted drill, the reamer body
Inside be provided with interior Cooling Holes, one end of interior Cooling Holes extends to afterbody, and water inlet is provided with afterbody, the interior Cooling Holes
The other end extend to knife neck, and connected with a point fluid apertures for the inside of knife neck, the other end of described point of fluid apertures extends to row
Consider the end of groove to be worth doing.
Preferably, the surface of the reamer body is provided with TiAlN coating.
Preferably, the afterbody is in flat.
Preferably, the shank section is provided with the circular arc that radius is 0.4mm with the junction of knife neck.
Preferably, inside of the described point of front end of fluid apertures positioned at the end of chip area.
Preferably, the spiral side edge has 6, and the front end of spiral side edge thickness of the thickness more than the tail end of spiral side edge
Degree.
Preferably, the end of the chip area extends to knife neck.
Preferably, the drift angle of the fluted drill is 135 degree.
Technique effect of the invention and advantage：A kind of surface of the reamer body of crudy reamer high is provided with aluminium nitride
Titanium coating, shank section is provided with the circular arc that radius is 0.4mm with the junction of knife neck, improves the intensity of cutter, reamer body
Tail end is provided with the afterbody of flat, is easy to the installation of cutter, prevents deviation, so that crudy is influenceed, reamer body
Inside be provided with interior Cooling Holes, one end of interior Cooling Holes extends to afterbody, and water inlet is provided with afterbody, interior Cooling Holes it is another
One end extends to knife neck, and is connected with a point fluid apertures for the inside of knife neck, and the front end of point fluid apertures is located at the end of chip area
It is internal, it is ensured that the cooling of cutter, processed surface smoothness is improved, crudy is improved, before side edge has 6, and spiral side edge
More than the thickness of the tail end of spiral side edge, larger in the amount of feeding, when rotating speed is very fast, protection blade is not damaged by the thickness at end, cuts with scissors
The front end of knife body is provided with fluted drill, and the drift angle of fluted drill is 135 degree, and secondary roughing is carried out before being finished, and is improved
Crudy, when using the reamer processing request relatively low workpiece, without carrying out roughing in advance, can be same by the reamer
Shi Jinhang roughing and finishing, improve processing efficiency.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The invention provides a kind of crudy as shown in Figure 1 reamer high, including afterbody 2, reamer body 3, handle of a knife
Portion 5, knife neck 6, blade part 8 and fluted drill 11, the tail end of reamer body 3 are provided with the afterbody 2 of flat, the front end of afterbody 2
Shank section 5 is provided with, the front end of shank section 5 is provided with knife neck 6, and shank section 5 is provided with radius for 0.4mm with the junction of knife neck 6
Circular arc, the front end of knife neck 6 is provided with blade part 8, and blade part 8 is provided with spiral side edge 9, and spiral side edge 9 has 6, and spiral
The thickness of the front end of side edge 9 is more than the thickness of the tail end of spiral side edge 9, and chip area 10 is provided between adjoining spiral side edge 9, arranges
The end for considering groove 10 to be worth doing extends to knife neck 6, and the front end of reamer body 3 is provided with the fluted drill 11 that drift angle is 135 degree, reamer body 3
Surface be provided with TiAlN coating, the inside of reamer body 3 is provided with interior Cooling Holes 4, and one end of interior Cooling Holes 4 extends to afterbody
2, and water inlet 1 is provided with afterbody 2, the other end of interior Cooling Holes 4 extends to knife neck 6, and with the inside of knife neck 6 point
