Abstract
The utility model belongs to the technical field of industrial cutters and discloses an end milling cutter. The end milling cutter comprises a tool shank and a tool bit, wherein the tool shank is cylindrical or cone-shaped, and a ring-shaped clamping groove is formed on the outer surface of the middle part of the tool shank; the tool shank and the tool bit are integral in structure, and cuttings chutes are formed on the tool bit; a helical and raised ridge extending to the front end part of the tool bit is formed between the cuttings chutes, two curved surfaces on the raised ridge intersect to form a main cutting edge, and 3 to 8 pairs of cutting edges are arranged at the front end part of the tool bit. According to the utility model, the helical cuttings chutes on the tool bit enable material chips left in milling during the workpiece processing process to be discharged quickly; during the manufacturing process, the main cutting edge on the raised ridge can prevent burrs to be produced on workpieces, and the workpiece processing quality is improved; and the end milling cutter provided by the utility model has a simple structure, is low in processing cost, is wear resisting and has a wide range of application.
Description
Technical field
The utility model belongs to industrial cutting-tool engineering field, refers in particular to a kind of slotting cutter.
Background technology
Slotting cutter is a kind of shank tools that the deep trouth on the box parts of machined grooves, step and various mutually perpendicular plane, particularly machined steel and cast iron is used; The standard slotting cutter is divided into two kinds of bastard and serrations; Often will process some mould or workpiece now, in process, not enough below existing: 1, the cutting edge of cutter is not sharp; Material bits can not be discharged very soon, influences next step continuation of processing work and process; 2, in processing, be easy to generate a lot of burrs on the workpiece, influence the quality of processing work; 3, cutter is easy to wear, and service life is short.
Summary of the invention
It is low, wear-resistant and be beneficial to the slotting cutter of quick chip removal that the purpose of the utility model provides a kind of processing cost.
The utility model is achieved in that
A kind of slotting cutter comprises handle of a knife and cutter head, and handle of a knife and cutter head are integral structure, and cutter head is provided with chip area; Form ridge spiral helicine and that extend to the cutter head leading section between the chip area, two surface intersections on the ridge form main cutting edges, and the cutter head leading section is provided with front cutting edge.
Described handle of a knife is cylinder or bullet.
The middle part outer surface of described handle of a knife is provided with an annular slot.
The front cutting edge of described cutter head leading section has 3-8.
The utility model is compared the outstanding advantage of prior art: the utility model cutter head is provided with spiral chip area, and material bits that can milling stays in the processing work process are discharged fast; In the process, the main cutting edge on the ridge can prevent to produce burr on the workpiece, has improved the quality of processing work; The utility model is simple in structure, and processing cost is low, and is wear-resistant, and applied range.
Description of drawings
Fig. 1 is the front view of the utility model.
Among the figure: the 1-handle of a knife; The 11-draw-in groove;
The 2-cutter head; The 21-ridge; The 22-chip area;
The 3-main cutting edge;
The 4-front cutting edge.
The specific embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1:
A kind of slotting cutter comprises handle of a knife 1 and cutter head 2, and handle of a knife 1 is an integral structure with cutter head 2, and such structure is simpler, low cost of manufacture; Cutter head 2 is provided with chip area 22, makes that the material bits in the cutting process can be discharged along chip area 22 fast, is unlikely to influence next step continuation of workpiece and processes; Form ridge 21 spiral helicine and that extend to cutter head 2 leading sections between the chip area 22, two surface intersections on the ridge 21 form main cutting edges 3, and cutter head 2 leading sections are provided with front cutting edge 4.
Described handle of a knife 1 is cylinder or bullet.
The middle part outer surface of described handle of a knife 1 is provided with an annular slot 11, makes can not cause slotting cutter loosening dropping in process by more firm grip handle of a knife of cutter holder.
The front cutting edge 4 of described cutter head 2 leading sections has 3-8.
The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection domain of the utility model.
