Abstract
A reamer comprises a reamer handle and a reamer head body, wherein the reamer head body is arranged at the front end of the reamer handle. The reamer head body comprises six edge bands which are respectively distributed on the reamer head body, the front ends of the six edge bands are respectively provided with edges, and a chip groove is formed between every two edge bands. The reamer is long in service life and high in processing precision, and evenly-divided angles formed by the cutting edges are changed to be unevenly-divided angles, thereby changing inherent vibration frequency of the reamer, eliminating a resonance phenomenon and improving roundness precision of a workpiece. The production cost is reduced remarkably, and good expected effect can be achieved.
Description
Technical field
The utility model relates to a kind of machining tool, particularly a kind of reamer.
Background technology
At present, also increasingly high because design level is increasingly high to the specification requirement of processing parts, the hole of the various high-precision requirement of ubiquity processing in the mechanical part processing.
The effect of reamer is to be used for fraising, improves the fineness in hole, the dimensional accuracy that guarantees the hole primary condition that is absolutely necessary; But the reamer of selling in the market all is to wait the reamer of cutting apart, because cutter and machine tool chief axis all have vibration, waits to cut apart because be again during use; So form resonance easily; The hole circle degree that causes cutting with scissors out is bad, and permissible accuracy is difficult for realizing, just can obtain expected effect.
The utility model content
The purpose of the utility model provides a kind of hinge and mills the combination cutter, when this cutter allowance is big, also can reach precision.
The technical scheme that adopts is:
A kind of reamer comprises handle of a knife and body of tool bit, and body of tool bit is installed in the front end of handle of a knife;
Body of tool bit comprises first land, second land, the 3rd land, the 4th land, the 5th land, the 6th land; First land, second land, the 3rd land, the 4th land, the 5th land, the 6th land are laid on the body of tool bit respectively; The front end of first land, second land, the 3rd land, the 4th land, the 5th land, the 6th land offers blade respectively, forms chip area between every land;
Become 60 ° of angles respectively between above-mentioned first land and second land, the 4th land and the 5th land; Become 63 ° of angles respectively between second land and the 3rd land, the 5th land and the 6th land, become 57 ° of angles respectively between the 3rd land and the 4th land, first land and the 6th land.
The advantage of the utility model is:
The utility model long service life, machining accuracy is high, and the angle of cutting apart of cutting edge is become not five equilibrium by five equilibrium, has so just changed the intrinsic frequency of vibration cutting, and the elimination covibration has improved the circularity precision of workpiece.Reduce production cost significantly, and can better produce a desired effect.

The specific embodiment
A kind of reamer comprises handle of a knife 1 and body of tool bit 4, and body of tool bit 4 is installed in the front end of handle of a knife 1;
Body of tool bit 4 comprises first land 5, second land 6, the 3rd land 7, the 4th land 8, the 5th land 9, the 6th land 10; First land 5, second land 6, the 3rd land 7, the 4th land 8, the 5th land 9, the 6th land 10 are laid in respectively on the body of tool bit 4; The front end of first land 5, second land 6, the 3rd land 7, the 4th land 8, the 5th land 9, the 6th land 10 offers blade 2 respectively, forms chip area 3 between every land;
Become 60 ° of angles respectively between above-mentioned first land 5 and second land 6, the 4th land 8 and the 5th land 9; Become 63 ° of angles respectively between second land 6 and the 3rd land 7, the 5th land 9 and the 6th land 10, become 57 ° of angles respectively between the 3rd land 7 and the 4th land 8, first land 5 and the 6th land 10.
