It is preferred that, the spiral side edge has 6, and thickness of the thickness more than the tail end of spiral side edge of the front end of spiral side edge
Degree.
It is preferred that, the end of the chip area extends to knife neck.
It is preferred that, the drift angle of the fluted drill is 135 degree.
Technique effect of the present utility model and advantage：A kind of surface of the reamer body of the high reamer of crudy is provided with nitrogen
Change aluminium 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 sheet
The tail end of body is provided with the afterbody in flat, is easy to the installation of cutter, prevents deviation, so that crudy is influenceed, reamer
The inside of body is provided with interior Cooling Holes, and one end of interior Cooling Holes extends to afterbody, and provided with water inlet, interior Cooling Holes at afterbody
The other end extend to knife neck, and connected with a point fluid apertures for the inside of knife neck, the front end of point fluid apertures is located at the end of chip area
The inside at end, it is ensured that the cooling of cutter, improves processed surface smoothness, improves crudy, and side edge has 6, and spiral side edge
Front end thickness be more than spiral side edge tail end thickness, it is larger in the amount of feeding, when rotating speed is very fast, protect blade not damaged
Bad, the front end of reamer 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,
Crudy is improved, when using the reamer processing request relatively low workpiece, without carrying out roughing in advance, the hinge can be passed through
Knife carries out roughing and finishing simultaneously, improves processing efficiency.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of high reamer of crudy as shown in Figure 1, including afterbody 2, reamer body 3,
Shank section 5, knife neck 6, blade part 8 and fluted drill 11, the tail end of reamer body 3 are provided with the afterbody 2 in flat, afterbody 2
Front end is provided with shank section 5, and the front end of shank section 5 is provided with knife neck 6, and the junction of shank section 5 and knife neck 6 is provided with radius
0.4mm 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
The thickness of the front end of spiral side edge 9 is more than the thickness of the tail end of spiral side edge 9, and chip area is provided between adjoining spiral side edge 9
10, the end of chip area 10 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
