Abstract
A diamond cover milling cutter comprises a cutter body and cutter blades, wherein the cutter body comprises a cutter handle, a cutter disc and four cutter blade mounting base bodies arranged on the cutter disc, each cutter blade mounting base body is provided with a cutter blade mounting step, the cutter blades are fixedly installed on the corresponding cutter blade mounting step by welding, the four cutter blade mounting base bodies extend out of the cutter disc along the axial direction; the cutter blade mounting base bodies are divided into a long type and a short type and are arranged symmetrically at intervals, the cutter blades are also divided into a long type and a short type, the long cutter blades are installed on the long cutter blade mounting base bodies, the short cutter blades are installed on the short cutter blade mounting base bodies, an included angle alpha is formed between the front cutter surfaces of the long cutter blades and the axial section of the cutter body, and semi-circular-arc-shaped notches are arranged at the middle parts of the cutting edges of the short cutter blades. According to the diamond cover milling cutter disclosed by the utility model, the four cutter blades are arranged by being divided into a long layer and a short layer, the cutter processing stability is ensured, the cutter vibrating phenomenon in the cutter processing process is avoided, in addition, the long cutter blades and the short cutter blades are matched with each other, so that the processing of the surface of a cylinder part can be finished by one time, the cutter does not need to be changed, the work efficiency is improved, the processing quality is also improved.
Description
Technical field
The utility model relates to the technical field of the dedicated tool of auto parts and components processing, particularly relates to a kind of diamond cover milling cutter.
Background technology
Some crucial auto parts and components needs to foreign round, and cylinder carries out retrofit; The surface also has protruding circular arc in addition; General cutter is difficult to once accomplish processing, must change other cutter and process, and still needs the secondary tool setting after the tool changing; Stay at surface to be machined unavoidably and connect the tool marks mark, influence the suface processing quality of workpiece.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of diamond cover milling cutter to be provided.
The technical scheme of the utility model is: a kind of diamond cover milling cutter; Comprise cutter hub and blade; Described cutter hub comprises handle of a knife, cutterhead and is arranged on the blade installation matrix on the cutterhead that be equipped with the blade installation step on each blade installation matrix, blade is fixedly mounted on its blade installation step through welding; It is four that described blade is installed matrix, stretches out cutterhead vertically; Blade is installed matrix has the long and short two kind; Be symmetrical set at interval; Described blade also is the long and short two kind, and long blade is installed in long blade and installs on the matrix, and shortened cutting blade is installed in shortened cutting blade and installs on the matrix; Between the rake face of described long blade and the axial section of cutter hub angle arranged, the cutting edge middle part of described shortened cutting blade is provided with the breach of semi arch.
The angle that has between the rake face of described long blade and the axial section of cutter hub is 5 °.
Rake face place at each blade on the described cutterhead is provided with the depression arcwall face, and this depression arcwall face extends to the edge of cutterhead.
The blade of described long blade is in the blade of the projection of axial direction and shortened cutting blade some length superposition section L of projection at axis direction, L >=0.5mm, adjacent this superposition section of the semicircle breach on the described shortened cutting blade.
There is 60 ° chamfering at the point of a knife place of described long blade.
The relief angle of described long blade and shortened cutting blade is 6 °.
The material of described long blade and shortened cutting blade is polycrystalline diamond.
The beneficial effect of the utility model
The diamond cover milling cutter of the utility model, blade amounts to 4, divides length two-layer setting; Guaranteed the cutter processing stability, avoided cutter to process the cutter phenomenon of shaking, the length blade cooperates in addition; Can once accomplish the processing of parts periphery; Avoid tool changing, improved operating efficiency, and improved crudy.
The rake face and the angle between the axial section of the cutting edge of long blade are 5 °, make point of a knife be higher than other points of cutting edge, improve the sharpness of blade, reduce cutting force, improve working (machining) efficiency, strengthen crudy.
