Abstract
The utility model belongs to the technical field of industrial cutters and discloses an end mill. The end mill comprises a mill handle and a mill head, wherein the mill handle is a cylindrical body or a cone-shaped body; an annular clamp groove is formed in the external surface of the middle of the mill handle; the mill handle and the mill head are in an integral structure; a chip groove is formed in the mill head; a spiral bulged ridge extending to the front end part of the mill head is formed in the middle of the chip groove; two curved surfaces on the bulged ridge are intersected to form a main cutting edge; 3-8 auxiliary cutting edges are arranged at the front end part of the mill head; and a chip breaking port for chip breaking is formed in the bulged ridge. According to the end mill, the spiral chip groove is formed in the mill head and can quickly remove chips caused by milling during workpiece machining; the main cutting edge on the bulged ridge can prevent burrs from being generated on a workpiece during the machining, so that the quality of the machined workpiece is improved; the end mill is simple in structure, low in machining cost, abrasion-resistant and wide in application scope; and the chip breaking port can prevent chip winding.
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, be machined grooves, step and various mutually perpendicular plane, a kind of shank tools of using of the deep trouth on the box parts of machined steel and cast iron particularly, the standard slotting cutter is divided into two kinds of bastard and serrations, often will process some mould or workpiece now, in process, have the following disadvantages: 1, the cutting edge of cutter is not sharp, material bits can not very fast discharge, influence next step continuation of processing work and processes; 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.
The utility model content
It is low, wear-resistant and be beneficial to the slotting cutter of quick chip removal that technical problem to be solved in 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, ridge is provided with main cutting edge, and the cutter head leading section is provided with front cutting edge, and described ridge is provided with the chip breaking mouth for chip breaking.
The utility model outstanding advantage compared to existing technology is: 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 from producing 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.The chip breaking mouth can be cut into segment with the smear metal that cutting produces, and can not be wound on the cutter head, has avoided the damage of smear metal to cutter head.
Description of drawings
Fig. 1 is the utility model structural representation.
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 and cutter head 2 are integral structure, 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 fast along chip area 22, 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 ridge 21 is provided with the chip breaking mouth 5 for chip breaking.
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 1 of cutter holder.
The front cutting edge 4 of described cutter head 2 leading sections has 3-8.
Above-described embodiment only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
