Abstract
The utility model discloses a flat spiral reamer, including handle of a knife and tool bit, be provided with the helicla flute on the tool bit, the blade line of helicla flute is 8~15 with the contained angle an of cutter central line, the utility model discloses improve the straight flute that sets up for the helicla flute on the cutter, will 0 former helical angle be processed into the helical angle of the number of degrees, vibrate at processing part in -process reamer so little, the precision that reams moreover height to arrange and cut the smoothness, improve production efficiency, practice thrift advantages such as cost.
Description
Technical field
This utility model patent relates to a kind of flat spiral reamer, belongs to and is exclusively used in blind hole processing technique field.
Background technology
At present, flat spiral reamer is for the blind hole process tool of Aero-Space, auto parts and components etc., former cutter is to use straight trough, helical angle is 0 °, but have the disadvantage that during the fraising of such cutter that in the first course of processing, the vibration of reamer is big, and the precision that reams is the highest, and arrange cut the most smooth etc., so existing flat spiral reamer is the most perfect.
Utility model content
The purpose of this utility model is: during a kind of simple in construction of offer, processing part, reamer vibration is little, and the precision that reams is high, and row cuts smoothness, improves production efficiency, and the flat spiral reamer of cost-effective one, to overcome the deficiencies in the prior art.
This utility model is achieved in that a kind of band end tooth blind hole spiral reamer, including handle of a knife and cutter head, is provided with helicla flute on cutter head, and described spiral fluted cutting edge line is 8 °～15 ° with the angle a of center cutter line.
Described angle a is 12 °.
Owing to have employed technique scheme, compared with prior art, the straight trough arranged on cutter is improved to helicla flute by this utility model, 0 ° of former helical angle is processed into the helical angle of the number of degrees, so during processing part, reamer vibration is little, and the advantage such as the precision that reams is high, row cuts smoothness, improves production efficiency, cost-effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Description of reference numerals: 1-handle of a knife, 2-helicla flute, 3-cutter head.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of band end tooth blind hole spiral reamer, including handle of a knife and cutter head, being provided with helicla flute on cutter head, described spiral fluted cutting edge line is 8 °～15 ° with the angle a of center cutter line, and the helical angle processing different material selections is different.
Described angle a is 12 °.
Embodiment 1: a kind of band end tooth blind hole spiral reamer, including handle of a knife 1 and cutter head 3, is provided with helicla flute 2 on cutter head 3, and the cutting edge line of described helicla flute 2 and the angle a of center cutter line are 8 °.
Embodiment 2: a kind of band end tooth blind hole spiral reamer, including handle of a knife 1 and cutter head 3, is provided with helicla flute 2 on cutter head 3, and the cutting edge line of described helicla flute 2 and the angle a of center cutter line are 15 °.
Embodiment 3: a kind of band end tooth blind hole spiral reamer, including handle of a knife 1 and cutter head 3, is provided with helicla flute 2 on cutter head 3, and the cutting edge line of described helicla flute 2 and the angle a of center cutter line are 12 °.
Embodiment 4: a kind of band end tooth blind hole spiral reamer, including handle of a knife 1 and cutter head 3, is provided with helicla flute 2 on cutter head 3, and the cutting edge line of described helicla flute 2 and the angle a of center cutter line are 10 °.
The straight trough arranged on cutter is improved to helicla flute by this utility model, 0 ° of former helical angle is processed into the helical angle of the number of degrees, and so during processing part, reamer vibration is little, and the precision that reams is high, and the advantages such as row cuts smoothness, improves production efficiency, cost-effective.
