Abstract
The utility model discloses a kind of superhard raceway groove milling cutter, comprise cutter hub, the outwardly formation boss of both sides the latter half of described cutter hub, the outer rim of described boss upper surface is for cutting main cutting edge, the side of boss is inclined-plane, and defining chip removal relief angle a between this inclined-plane and boss upper surface, this chip removal relief angle a is between 75 °-77 °; The position corresponding with boss in the first half of cutter hub is also provided with two locating surfaces.The utility model compares the life-span that similar blade can improve more than 4 times, decreases production cost, improves productivity effect.
Description
Technical field
The utility model relates to a kind of machining tool, especially relates to a kind of superhard raceway groove milling cutter.
Background technology
Milling cutter is for Milling Process, the rotary cutter with one or more cutter tooth.During work, each cutter tooth cuts the surplus of workpiece successively off and on.The thin milling cutter of existing raceway groove has the problem that hardness is not high and cutting precision is not high of cutting.
Utility model content
The utility model, in order to overcome above-mentioned deficiency, provides the superhard raceway groove milling cutter that a kind of hardness is high, precision is high.
The technical solution of the utility model is as follows:
A kind of superhard raceway groove milling cutter, comprise cutter hub, the outwardly formation boss of both sides the latter half of described cutter hub, the outer rim of described boss upper surface is for cutting main cutting edge, namely twolip is had, the side of boss is inclined-plane, and defines chip removal relief angle a between this inclined-plane and boss upper surface, and this chip removal relief angle a is between 75 °-77 °; The position corresponding with boss in the first half of cutter hub is also provided with two locating surfaces.
The center of described cutter hub also has fixed installation hole.
The beneficial effects of the utility model are:
Use twolip to cut in the utility model simultaneously, ensure that the overall uniform force degree of blade, extend the service life of blade, and adopt Central Symmetry to cut, make to improve machining accuracy in blade cut process, improve craft precision.The utility model compares the life-span that similar blade can improve more than 4 times, decreases production cost, improves productivity effect.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is front view of the present utility model;
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Superhard raceway groove milling cutter as depicted in figs. 1 and 2, comprises cutter hub 5, has fixed installation hole 3 in the center of cutter hub 5.The outwardly formation boss of both sides the latter half of described cutter hub 5, the outer rim of described boss upper surface is for cutting main cutting edge 1, and namely have employed twolip cuts simultaneously, can ensure the overall uniform force degree of blade, extends the service life of blade.And due to twolip symmetrical, centered by symmetrically to cut, make to improve machining accuracy in blade cut process, improve craft precision.The side of described boss is inclined-plane 2, and defines chip removal relief angle a between this inclined-plane 2 and boss upper surface, and this chip removal relief angle a is between 75 °-77 °; Two locating surfaces 4 are also provided with in the position that the first half of cutter hub 5 is corresponding with boss.
Above-mentioned is enlightenment according to the utility model, and by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
