Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Change as shown in Figure 2,3 and amendment.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
As shown in Figure 2,3, high-accuracy forming reamer 100 of the present invention comprises: cutter hub 10, be formed at the cutter head 20 of cutter hub one end.Wherein, described cutter head in the design process, reduces described tool cutting edge angle, to improve the guidance quality of cutter, and reduces the friction of rear knife face and workpiece by increasing relief angle, to improve machined surface roughness.Particularly, described tool cutting edge angle is 55 ~ 65 °; Described relief angle is 7 ~ 9 °.
The end of described cutter head 20 is formed with the first cutting edge 21, and this first cutting edge 21 is RC type.Setting like this, makes cutting edge elongated, and transition is steady, cuts more brisk.
Described cutter head 20 is also formed with some fraising portions 22.Described first cutting edge 21 pairs of machined materials carry out cutting perforate, and the size of multiple fraising portions 22 to the hole offered is widened, and forms trapezoidal hole structure.In described adjacent fraising portion 22, the diameter away from the fraising portion 22 of described first cutting edge 21 is greater than the diameter in the fraising portion 22 near described first cutting edge 21.Thus some fraising portions 22 form forge piece of step type structure.Further, the wall that described cutter head 20 contacts with the hole wall of the described shoulder hole be processed to form forms the forming surface of described cutter head.Thus various structures reamer is combined with corresponding shaping face by it, can the corresponding shoulder hole in the shaping place of time processing, working (machining) efficiency and machining accuracy high.
