Abstract
A cutter with double grooves comprises a cutter body and a cutter bit connected with the front end of the cutter body. The cutter bit is provided with a main cutting blade and a chamfering blade, the main cutting blade and the chamfering blade are arranged alternately, a main cutting blade groove is formed between the blade surface of the main cutting blade and the back of the chamfering blade, and a chamfering blade groove is formed between the blade surface of the chamfering blade and the back of the main cutting blade. According to the cutter, the main cutting blade groove formed between the blade surface of the main cutting blade and the back of the chamfering blade and the chamfering blade groove formed between the blade surface of the chamfering blade and the back of the main cutting blade are made to be in different directions, therefore, the main cutting blade and the chamfering blade are made to be in different directions, during sharpening, the sharpening length of the main cutting blade portion cannot be affected by the chamfering blade portion, and the sharpening times are increased.
Description
Technical field
The utility model relates to a kind of machining tool, especially a kind of multiple ditch cutter.
Background technology
At present, because design level is more and more higher, also more and more higher to the specification requirement of processing parts.
Because existing cutter is free cutter part 101(as shown in Figure 1 at chamfering root), cutter is actual is the version that a diameter adds a chamfering, and step section to differ from 102 length very short.Therefore when cutting blade serious wear, need to grind while repairing, step section differs from 102 land 103(as shown in Figure 2) length shortens, and empty cutter part 101 lengthenings, have caused scrapping of cutter.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, wear-resisting durable multiple ditch cutter.
The utility model solves the technical scheme that prior art problem adopts: multiple ditch cutter, comprise cutter hub and the cutter head being connected with described cutter hub front end, described cutter head is established and is comprised main cutting edge and chamfering blades, described main cutting edge and chamfering blades alternative arrangement, and between the blade face of described main cutting edge and the back of described chamfering blades, form main cutting flute, between the blade face of described chamfering blades and the back of described main cutting edge, form chamfering flute.
The beneficial effects of the utility model are: the utility model is by becoming the chamfering flute forming between the blade face of the main cutting flute forming between the blade face of main cutting edge and the back of chamfering blades and chamfering blades and the back of main cutting edge into different directions, thereby main cutting edge and chamfering blades are become to different directions, like this when mill is repaiied, chamfering blades part just can not have influence on the slender degree of mill of main cutting edge part, has increased the number of times that mill is repaiied.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model prior art.
Fig. 2 is the schematic diagram of the utility model prior art tool bit part.
Fig. 3 is overall structure schematic diagram of the present utility model.
Fig. 4 is cutter head schematic cross-section of the present utility model.
In figure, 1-cutter hub, 2-cutter head, 3-main cutting edge, 4-chamfering blades, 5-main cutting flute, 6-chamfering flute, cold hole in 7-, the empty cutter part of 101-, 102-step section are poor, 103-land.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described:
Fig. 2 is the overall structure schematic diagram of the multiple ditch cutter of the utility model.Multiple ditch cutter, comprises cutter hub 1 and the cutter head 2 being connected with described cutter hub 1 front end, and Fig. 3 is the cutter head schematic cross-section of the multiple ditch cutter of the utility model.The Wei Neileng hole, center 7 of cutter head 2, cutter head 2 comprises main cutting edge 3 and chamfering blades 4, described main cutting edge 3 and chamfering blades 4 alternative arrangements, and between the blade face of main cutting edge 3 and the back of described chamfering blades 4, form main cutting flute 5, between the blade face of chamfering blades 4 and the back of described main cutting edge 3, form chamfering flute 6.Main cutting flute 5 is different from the direction of chamfering flute 6.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
