Abstract
Ball end mill, including the handle of a knife portion and the cutting portion that set gradually, cutting portion includes two pieces of bottom edge that the spiral wound two pieces of circumference edge establishing laterally and set up at the tip, and two pieces of circumference edge are knife face behind the circumference edge rake face that sets gradually and circumference edge all, encloses into the chip pocket to the side of circumference edge rake face and the cutting portion, and the knife face includes first surface, second curved surface and the concave surface of setting between first surface and second curved surface behind the circumference edge, among the prior art behind the circumference edge knife face be horizontal plane, the utility model discloses an improve knife face behind the circumference edge for the curved surface, thereby make the intensity that increases the cutter blade, make the blade more wear -resisting, increase milling cutter's life, reduce loss cost.
Description
Technical field
The utility model is related to the process tool of industry cutting, is related specifically to rose cutter.
Background technology
Milling cutter, as has cylindrical shape, and carries cutting edge in circumference and bottom, drives it to be revolved by lathe
Transfer and machining is carried out to workpiece；Rose cutter belongs to one of milling cutter, is mainly used in processing groove and step surface etc., knife
On circumference and end face, in prior art, after the circumference sword of rose cutter, knife face is all horizontal plane to tooth, circle in cutting process
After Zhou Ren, easily wear and tear in knife face and shear blade junction, and the service life of milling cutter is short.
Utility model content
The utility model be directed to above-mentioned background in deficiency, after now providing a kind of circumference sword knife face be curved surface, be difficult
The rose cutter of abrasion.
The technical scheme that it is realized is as follows:
Rose cutter, including the shank section setting gradually and cutting portion, described cutting portion includes spiral winding and is located at side
Two pieces of circumference swords and two pieces of shear blades being arranged on end, two pieces of described circumference swords all include the circumference sword rake face setting gradually and
Knife face after circumference sword, described circumference sword rake face and cutting portion side surround chip pocket, and after described circumference sword, knife face includes first
Curved surface, the second curved surface and the concave surface being arranged between described first surface and the second curved surface.
Preferably, the helical angle of two pieces of described circumference swords is all in the range of 34 ° to 36 °.
The beneficial effects of the utility model are: after circumference sword in prior art, knife face is horizontal plane, and the utility model leads to
Crossing and knife face after circumference sword is improved to curved surface, making, thus increasing the intensity of cutting edge roundness, to make cutting edge more wear-resisting, increase milling cutter
Service life, reduce loss cost.
Brief description
With specific embodiment, the utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present utility model；
Fig. 2 is the generalized section of a-a in the utility model Fig. 1；
Fig. 3 is close-up schematic view of the present utility model.
Specific embodiment
As depicted in figs. 1 and 2, rose cutter, including the shank section 1 setting gradually and cutting portion 2, described cutting portion 2 wraps
Include spiral winding and be located at two pieces of circumference swords 3 of side and two pieces of shear blades being arranged on end, two pieces of described circumference swords 3 are all included successively
Knife face 5 after the circumference sword rake face 4 of setting and circumference sword, described circumference sword rake face 4 surrounds chip pocket 6 with cutting portion side,
After described circumference sword, knife face 5 includes first surface 7, the second curved surface 8 and is arranged between described first surface 7 and the second curved surface 8
Concave surface 9, helical angle a of two pieces of described circumference swords 3 is all in the range of 34 ° to 36 °；Before improvement, after circumference sword, knife face 5 is level
Plane, easily weares and teares in working angles, and physical life is short, and knife face 5 is designed as curved surface after circumference sword, makes thus increasing
The intensity of cutting edge roundness, makes cutting edge more wear-resisting, increases the service life of milling cutter, reduce loss cost.
The announcement of book and enlightenment according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying carries out suitable change and modification.Therefore, the utility model is not limited to the disclosure above and being embodied as of describing
Mode, the basic transformation of all various mechanisms being made based on this patent is it should also include the guarantor of claim of the present utility model
In the range of shield.Although additionally, employing some specific terms in this specification, these terms are intended merely to more convenient saying
Bright, any restriction can not be constituted to the utility model.
Claims (2)
1. rose cutter, including the shank section setting gradually and cutting portion it is characterised in that described cutting portion includes spiral winding
Two pieces of circumference swords in side and two pieces of shear blades being arranged on end, two pieces of described circumference swords all include the circumference sword setting gradually
