Abstract
The utility model provides a novel finish machining milling cutter which comprises a cutter head, a cutter bar and a cutter holder, wherein scrap discharge grooves are formed in the cutter bar; a pair of centrosymmetric main cutting edges are arranged on the cutter head; sleeking minor edges are arranged at the positions that any main cutting edge rotates by 30 degrees in the clockwise direction; the outer diameters of the sleeking minor edges are larger than that of the main cutting edges; an inner cooling hole is formed in the axle center part of the novel finish machining milling cutter, and penetrates through the whole novel finish machining milling cutter; two cooling grooves are formed in the front end parts of the cutter head, and is connected with the inner cooling hole. In the cutting process, the main cutting edges carry out rough processing, the sleeking minor edges carry out small amount of finish machining, a needed product can be processed in one step, human and material resources are saved, and the work efficiency is improved; besides, through the design of the inner cooling hole and the cooling grooves, the inner cooling can be enhanced, the condition that the cutter is broken due to overheat is reduced, so that the durability and the wearing resistance of the cutter are improved.
Description
Technical field
The utility model relates to a kind of cutter for milling machine processing, relates in particular to a kind of Novel precise milling cutter processing.
Background technology
Blade shapes has a variety of, and plain-milling machine and CNC milling machine, for working groove and outline of straight line, mill boring for processing cavity, core, curved profile and profile.Now more milling cutter is for hole processing and pocket machining, generally will first carry out roughing man-hour adding, and then changes milling cutter and carries out semifinishing, and then change milling cutter and carry out fine finishining, so just can achieve the goal, but such operation needs often to change milling cutter, work loaded down with trivial details, efficiency is low; In addition, in process, milling cutter runs up, and causes the milling cutter excess Temperature, easily produces the problems such as buildup, tipping, wearing and tearing, cutter fracture, working (machining) efficiency is low.
The utility model content
The utility model provides a kind of Novel precise milling cutter processing, high chip removal, and Cooling Holes in band, easy to wear, fracture, working (machining) efficiency is not high.
The technical solution of the utility model is: a kind of Novel precise milling cutter processing, comprise cutter head, knife bar and handle of a knife, knife bar is provided with chip area, it is characterized in that: described cutter head is provided with a pair of centrosymmetric main cutting edge, described any main cutting edge is rotated in a clockwise direction 30 ° and locates to be provided with the secondary sword of smoothing, and the secondary sword external diameter of described smoothing is greater than the external diameter of main cutting edge; Described Novel precise milling cutter processing axis part is provided with interior Cooling Holes, and described interior Cooling Holes runs through whole Novel precise milling cutter processing, and the leading section of described cutter head is provided with two cooling baths, and described any cooling bath is connected with interior Cooling Holes.
Further, the secondary sword external diameter of described smoothing is than the large 0.05mm of main cutting edge external diameter.
The beneficial effects of the utility model are: cutter head of the present utility model is provided with a pair of main cutting edge and the secondary sword of a pair of smoothing, when machining, main cutting edge carries out roughing, the secondary sword of smoothing carries out the fine finishining of little surplus, can time processing go out needed product, the resource that uses manpower and material resources sparingly, increase work efficiency; In addition, the utility model is provided with interior Cooling Holes and cooling bath, cooling in strengthening, and reduces cutter and damages because of overheated, thereby improve tool life and wearability.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made to brief description.
As shown in the figure: a kind of Novel precise milling cutter processing, comprise cutter head 1, knife bar 2 and handle of a knife 3, knife bar 2 is provided with chip area 4, it is characterized in that: described cutter head 1 is provided with a pair of centrosymmetric main cutting edge 5, described any main cutting edge 5 is rotated in a clockwise direction 30 ° and locates to be provided with the secondary sword 6 of smoothing, and secondary sword 6 external diameters of described smoothing are than the large 0.05mm of main cutting edge 5 external diameter; Described Novel precise milling cutter processing axis part is provided with interior Cooling Holes 7, and described interior Cooling Holes 7 runs through whole Novel precise milling cutter processing, and the leading section of described cutter head 1 is provided with two cooling baths 8, and described any cooling bath 8 is connected with interior Cooling Holes 7.
Working method: during use, main cutting edge 5 carries out roughing, the secondary sword 6 of smoothing carries out the fine finishining of little surplus, can disposablely process required product, and resource uses manpower and material resources sparingly, increase work efficiency, in addition, the design of interior Cooling Holes 7 and cooling bath 8, cooling in strengthening, reduce cutter and damage because of overheated, thereby improve tool life and wearability.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
