Abstract
The invention discloses a coarse-fine milling cutter capable of discharging scraps quickly. The coarse-fine milling cutter comprises a cutter handle and a cutter head connected with one end of the cutter handle, the cutter head is provided with spiral cutting edges, the cutting edges comprise coarse cutting edges and fine cutting edges, a scrap discharging groove is formed between two adjacent cutting edges, a strip-shaped protrusion is arranged at the bottom of each of the scrap discharging grooves and extends from the front section of the corresponding scrap discharging groove to the rear end of the corresponding scrap discharging groove, and an annular clamping groove is formed in the cutter handle. The strip-shaped protrusions can perform the function of dredging scraps so that the scrap discharging grooves of the cutter head cannot be blocked by the scraps, and the drilling speed is improved; meanwhile, the cutter head is coated with a chromium nitride coating which can effectively reduce abrasion of the cutter head, and accordingly the service life of the milling cutter is prolonged.
Description
Technical field
The present invention relates to field of machining, be specifically related to a kind of thick milling cutter of chip removal fast.
Background technology
When using cutter to carry out processing work, generally first roughing is carried out to workpiece, and then fine finishining is carried out to workpiece, present appearance one arranges rough cut sword and smart cutting edge on cutter head simultaneously, but in process, if the scrap produced can not be discharged fast timely, be easy to next step continuation processing affecting processing work; Meanwhile, the continuous friction of cutter and workpiece, cutter is easy to wearing and tearing, and service life is short; If the clamping of handle of a knife loosely in addition, be easy to occur loosening.
Summary of the invention
The object of this invention is to provide a kind of can in time chip removal fast, the life-span long thick milling cutter of quick chip removal.
The present invention is achieved through the following technical solutions: a kind of thick milling cutter of chip removal fast, comprise handle of a knife and the cutter head being connected to handle of a knife one end, described cutter head is provided with helical cutting edge, described cutting edge comprises rough cut sword and smart cutting edge, chip area is formed between described cutting edge, the bottom land of described chip area is provided with bar shaped projection, and described bar shaped projection extends to the rear end of this chip area from chip area leading portion, described handle of a knife is provided with an annular slot.
Described cutting edge has four, and described cutting edge comprises two rough cut swords and two smart cutting edges.
Two described rough cut swords and two smart cutting edges are spaced.
Described cutter head outer surface has chromium nitride coating; The wearing and tearing of effective minimizing cutter head, improve the service life of milling cutter.
Beneficial effect of the present invention is: cutting edge is divided into rough cut sword and smart cutting edge, decreases operation, improves efficiency; Be provided with bar shaped projection at the bottom of flute, when cutter head is when holing chip removal, its bar shaped projection can play the effect at dredging bits end, the chip area of cutter head can not be squeezed by bits end stifled, improves penetration rate; There is chromium nitride coating at cutter head outer surface simultaneously; The wearing and tearing of effective minimizing cutter head, improve the service life of milling cutter; Handle of a knife is also provided with annular slot, makes cutter holder more firmly can clamp handle of a knife, prevent milling cutter loose or dislocation in process.
Accompanying drawing explanation
Fig. 1 is the structural representation of the thick milling cutter of a kind of quick chip removal of the present invention.
1 is cutter head, and 2 is handle of a knife, and 3 is annular slot, and 4 is rough cut sword, and 5 is smart cutting edge, and 6 is chip area, and 7 is bar shaped projection.
Detailed description of the invention
With reference to Fig. 1, a kind of thick milling cutter of chip removal fast, comprise handle of a knife 2 and the cutter head 1 being connected to handle of a knife 2 one end, described cutter head 1 is provided with helical cutting edge, described cutting edge comprises rough cut sword 4 and smart cutting edge 5, forms chip area 6 between described cutting edge, and the bottom land of described chip area 6 is provided with bar shaped projection 7, described bar shaped projection 7 extends to the rear end of this chip area 6 from chip area leading portion, described handle of a knife is provided with an annular slot 3.
Described cutting edge has four, and described cutting edge comprises two rough cut swords 4 and two smart cutting edges 5.
Two described rough cut swords and two smart cutting edges are spaced.
Described cutter head 1 outer surface has chromium nitride coating; The wearing and tearing of effective minimizing cutter head, improve the service life of milling cutter.
Cutting edge is divided into rough cut sword and smart cutting edge, decreases operation, improves efficiency; Be provided with bar shaped projection at the bottom of flute, when cutter head is when holing chip removal, its bar shaped projection can play the effect at dredging bits end, the chip area of cutter head can not be squeezed by bits end stifled, improves penetration rate; There is chromium nitride coating at cutter head outer surface simultaneously; The wearing and tearing of effective minimizing cutter head, improve the service life of milling cutter; Handle of a knife is also provided with annular slot, makes cutter holder more firmly can clamp handle of a knife, prevent milling cutter loose or dislocation in process.
