Abstract
The utility model relates to a knife, particularly a chamfering knife for minute surface machining. The chamfering knife for minute surface machining includes a knife body and a blade connected at the front end of the knife body, wherein the cutting edge of the blade is provided with an edge inclined angle, the blade is provided with a cutting edge first rear angle and a cutting edge second rear angle, and an edge area is arranged between the two rear angles of the cutting edge. The chamfering knife for minute surface machining is high in machining efficiency and improves the precision of the machining surface roughness.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of rose reamer that is used for mirror finish.
Background technology
The mirror finish of the difficult-to-machine materials such as mirror finish, especially aluminium alloy in mobile phone electronic machinery industry requires the machined surface roughness precision high; The rose reamer cutting edge that is used for mirror finish in the prior art does not have the inclination angle; Contact-making surface is big during cutting, and cutting force is not concentrated, and working (machining) efficiency is low; And owing to there is not the existence of land, chip removal has some setbacks influences working (machining) efficiency; And because the hardness of blade material is low, make edge radius big, influence the precision of machined surface roughness.
Summary of the invention
Solve existing problem in the above-mentioned prior art for better, this uses be novel to provide a kind of working (machining) efficiency height, makes the rose reamer that is used for mirror finish that the machined surface roughness precision is high.
In order to realize the foregoing invention purpose; The technical scheme of the utility model is: a kind of rose reamer that is used for mirror finish, comprise cutter hub, and be connected the blade of cutter hub front end; Wherein, The cutting edge of blade is provided with cutting edge inclination, and blade is provided with cutting edge first relief angle and cutting edge second relief angle, is provided with land between two cutting edge relief angles.
The utility model is used for the rose reamer of mirror finish, and wherein, said cutting edge first relief angle is 3 °-6 °.
The utility model is used for the rose reamer of mirror finish, and wherein, said cutting edge second relief angle is 19 °-21 °.
The utility model is used for the rose reamer of mirror finish, and wherein, said cutting edge cutting edge inclination is 3 °-5 °.
The utility model is used for the rose reamer of mirror finish, and wherein, said cutter hub material is a carbide alloy, and the blade material is a natural diamond.
Beneficial effect: 1, the rose reamer mirror finish efficient that is used for mirror finish of the utility model is high.The rose reamer cutting edge that is used for mirror finish of the utility model has increased cutting edge inclination, and contact point reduces during cutting, and cutting force is concentrated, thereby makes the sharp working (machining) efficiency that improved of cutting edge; The increase of the rose reamer cutting edge land that is used for mirror finish of the utility model is beneficial to chip removal, thereby has also improved working (machining) efficiency.2, the utility model rose reamer of being used for mirror finish has improved the precision of machined surface roughness.The rose reamer blade that is used for mirror finish of the utility model adopts natural diamond to make that the hardness of blade is very high; Radius of edge can reach 0.01-0.002 μ m behind the cutter fine gtinding; It is smooth that blade is still observed blade through 1500 times of high power amplifications; Use the rose reamer processing that is used for mirror finish of the utility model, machined surface roughness R
aBe 15-50 μ m, cooperate fine turning lathe to carry out precision and extra accuracy processing, obtain specular surface.
