Abstract
The utility model relates to a spherical milling cutter, which comprises a cutter arbor and a working portion integrally connected with the cutter arbor. A milling blade is arranged on an axial end surface of the working portion, a chip removal groove is disposed on the peripheral surface of the working portion, the milling blade comprises a first arc milling blade and a second arc milling blade, tops of the first arc milling blade and the second arc milling blade extend towards an axis line of the cutter arbor and are intersected to form a sphere milling blade, roots of the first arc milling blade and the second arc milling blade extend towards the working portion, and sphere radian of the sphere milling blade consisting of the first arc milling blade and the second arc milling blade ranges from 190 degrees to 220 degrees. After the spherical milling cutter is deflected via a deflecting fixture during a milling process, a milling center point can be changed along the deflection of the spherical milling cutter, namely, the milling center point is not limited on the axis of the milling cutter and can be an optional point on the sphere cutting blade, abrasion to the milling cutter can be reduced, and the service life of the milling cutter is prolonged.
Description
Technical field
The utility model relates to the metal cutting tool in a kind of mechanical processing industry, is specifically related to a kind of ball-type milling cutter.
Background technology
When the processing notebook computer shell, need to adopt the ball-type milling cutter, the ball-type milling cutter in order to reduce its wearing and tearing, needs to use the nutation type anchor clamps that it is located before use.But because the radian of the sphere milling edge of ball-type milling cutter is 180 °, the central point of milling cutter remains vertical with working face, milling cutter in the course of the work, no matter how the beat anchor clamps carry out beat to it, the sphere centre point of ball-type milling cutter (sphere centre point and milling cutter axis coinciding) always contacts with workpiece at first, be that the linear velocity that sphere centre is put relative workpiece is zero, so long-term use then can be accelerated the cutting face wearing and tearing, the cutting face rust, cause the lost of life of ball-type milling cutter, thereby make the ball-type milling cutter scrap.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of ball-type milling cutter that can increase the service life.
The technical scheme that realizes the utility model purpose is as follows:
A kind of ball-type milling cutter, comprise handle of a knife and the working portion that is connected as a single entity with handle of a knife, the axial end of described working portion is provided with milling edge, the side face of working portion is provided with chip area, described milling edge comprises the first circular arc milling edge, the second circular arc milling edge, the first circular arc milling edge, the top of the second circular arc milling edge is also passed through mutually to the axial line extension of handle of a knife and is constituted the sphere milling edge, the first circular arc milling edge, the root of the second circular arc milling edge extends to working portion, and is described by the first circular arc milling edge, the sphere radian of the sphere milling edge that the second circular arc milling edge constitutes is 190 °-220 °.
Described chip area comprises the first straight chip area, the second straight chip area that is separately positioned on the first circular arc milling edge, the second circular arc milling edge, one side.
Adopted above-mentioned scheme, the top of the first circular arc milling edge, the second circular arc milling edge is also passed through mutually to the axial line extension of handle of a knife and is constituted the sphere milling edge, the root of the first circular arc milling edge, the second circular arc milling edge extends to working portion, and the sphere radian of the sphere milling edge that is made of the first circular arc milling edge, the second circular arc milling edge is 190 °-220 °.The ball-type milling cutter is in milling process like this, after by the beat anchor clamps it being carried out beat, the milling central point can change thereupon, be that the milling central point no longer limits on the axle center that is positioned at milling cutter, the milling central point can on the sphere milling edge more arbitrarily, in milling process, with the rotating speed of the relative workpiece of sphere milling central point of milling cutter axis coinciding no longer is zero, therefore, can reduce wearing and tearing, prolong the service life of milling cutter milling cutter.
