Abstract
The utility model discloses a kind of two and grind milling cutter construction, comprise a shank and a blade, between described shank and blade, be fixedly connected with connecting portion, described blade surface spiral is provided with left-hand screw discharge gutter and right-hand screw discharge gutter, described left-hand screw discharge gutter and the mutual cross arrangement of right-hand screw discharge gutter; Described left-hand screw discharge gutter is six, and described right-hand screw discharge gutter is seven; Of the present utility model two grind the left-hand screw discharge gutter of milling cutter blade surface helical design and rigidity and the crudy that right-hand screw discharge gutter can be taken into account milling cutter, and of the present utility model two structures of grinding milling cutter can be saved carbonization wolfram steel consumption, reduce the cost of manufacture of milling cutter.
Description
Technical field
The utility model relates to the cutting-tool engineering field of PCB use in printed circuit board, relates in particular to a kind of two and grinds milling cutter construction.
Background technology
Traditional milling cutter is comprised of shank and blade, single or a plurality of chip discharge ditches of the peripheral formation of blade, cutting discharge gutter from blade top to blade bottom is fixed design, when design, although use the larger angle of rifling to promote the crudy of milling cutter, but the larger angle of rifling declines the rigidity of milling cutter, and the precision of the product of processing is just not high; Though use the less angle of rifling can promote the rigidity of milling cutter, the quality of processing will decline.In addition, existing milling cutter is to be made by high rigidity wolfram steel material, and carbonization wolfram steel is rare metal, is the strategic materials of China, and milling cutter cost of manufacture is high, and traditional milling cutter manufacture and shape and structure do not conform to economic benefit.
Utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of two to grind milling cutter construction, and the left-hand screw discharge gutter and the right-hand screw discharge gutter that by blade surface spiral, are provided with, can take into account two rigidity and the crudies of grinding milling cutter.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of two grind milling cutter construction, comprise a shank and a blade, between described shank and blade, be fixedly connected with connecting portion, described blade surface spiral is provided with left-hand screw discharge gutter and right-hand screw discharge gutter, described left-hand screw discharge gutter and the mutual cross arrangement of right-hand screw discharge gutter; Described left-hand screw discharge gutter is six, and described right-hand screw discharge gutter is seven, and of the present utility model two grind the left-hand screw discharge gutter of milling cutter blade surface helical design and rigidity and the crudy that right-hand screw discharge gutter can be taken into account milling cutter.
Further, the helical angle of described left-hand screw discharge gutter and right-hand screw discharge gutter is 20 °.
As the improvement of such scheme, the spiral on described blade surface is long is 8mm.
As the improvement of such scheme, the diameter of described blade is 1.3mm.
As the improvement of such scheme, it is conical that described connecting portion is, and less one end is connected with described blade, and larger one end is connected with described shank.
Further, the angle of the taper seat of described connecting portion and the axis of rotation of shank is 15 °.
As the improvement of such scheme, the diameter of described shank is that 3.16mm is to 3.175mm.
With respect to prior art, the beneficial effects of the utility model are: of the present utility model two grind rigidity and the crudy that left-hand screw discharge gutter that milling cutter blade surface spiral is provided with and right-hand screw discharge gutter can be taken into account milling cutter.In addition, of the present utility model two structures of grinding milling cutter can be saved carbonization wolfram steel consumption, reduce the cost of manufacture of milling cutter.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing to embodiment is briefly described.
Fig. 1 is the structural representation that two of the utility model preferred embodiment grinds milling cutter construction.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
If Fig. 1 is that two of the utility model preferred embodiment grinds milling cutter construction structural representation, of the present utility model two grind milling cutter construction comprises a shank 1 and a blade 2, between described shank 2 and blade 1, be fixedly connected with connecting portion 3, the surperficial spiral of described blade 2 is provided with left-hand screw discharge gutter 4 and right-hand screw discharge gutter 5, described left-hand screw discharge gutter 4 and the mutual cross arrangement of right-hand screw discharge gutter 5; Described left-hand screw discharge gutter 4 is six, and described right-hand screw discharge gutter 5 is seven.
Further, in an embodiment of the present utility model, the helical angle of described left-hand screw discharge gutter 4 and right-hand screw discharge gutter 5 is 20 °.
In an embodiment of the present utility model, the spiral on described blade 2 surfaces is long is 8mm.
In an embodiment of the present utility model, the diameter of described blade 2 is 1.3mm.
In an embodiment of the present utility model, it is conical that described connecting portion 3 is, and less one end is connected with described blade 2, and larger one end is connected with described shank 1.
In an embodiment of the present utility model, the angle of the axis of rotation of the taper seat of described connecting portion 3 and shank 1 is 15 °.
In an embodiment of the present utility model, the diameter of described shank 1 is that 3.16mm is to 3.175mm.
Of the present utility model two to grind milling cutter be the milling cutter that money is turned waste into wealth, and is to reclaim at user side the useless milling cutter of using, and is reprocessed into the needed milling cutter product of client.Be mainly wherein to have increased flow process new technology, new equipment, adopts special emery wheel, to reclaiming useless milling cutter, carries out axially grinding the pre-treatment of end and radial grinding new technology, for follow-up milling cutter processing provides reliable guarantee.Of the present utility model two grind rigidity and the crudy that left-hand screw discharge gutter 4 that the surperficial spiral of milling cutter blade 2 is provided with and right-hand screw discharge gutter 5 can be taken into account milling cutter.In addition, of the present utility model two structures of grinding milling cutter can be saved carbonization wolfram steel consumption, reduce the cost of manufacture of milling cutter.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
