Abstract
The utility model discloses a welded type superhard bulb milling cutter with a curved edge, which consists of a cutter holder part and a cutting part, wherein, the cutting part is made up of a curvededge superhard bulb head blade and a cutting part bulb, the curved edge superhard bulb blade adopts a curved surface, and the curved edge superhard bulb blade is made of cubic boron nitride. When thecurved edge blade is used in cutting a workpiece, the cutting edge is in partial contact with the workpiece, with smaller cutting resistance, lower cutting temperature, relatively steady cutting and easy chip discharge, thereby not only improving the surface quality of the workpiece subject to machining and prolonging the service life of the cutter.
Description
Technical field
The utility model relates to a kind of mechanical field milling cutter, relates in particular to a kind of superhard rose cutter of welded type of curve sword.
Background technology
PCD and CBN are two kinds of the highest materials of hardness up to the present in the world.Because it has high rigidity and high-wearing feature, be world today's green processing, with car for mill, to mill the main body cutter of generation mill, hard attitude processing, high-speed cutting, DRY CUTTING.Superhard cutter has become indispensable important means in the machining.Present Superhard composite film (PCD or CBN composite sheet) is plane, after they are cut into suitable shape and are welded on the cutter hub, has just made superhard cutter, as shown in Figure 1.Common superhard rose cutter, its superhard part is plate.Like this, during rose cutter work, whole blade is contact workpiece simultaneously, and the impulsive force that cutter is subjected to is very big, and cutter vibrates easily, and blade collapses damage easily, and the surface quality of workpiece to be machined is poor.The utility model is made the curved surface form with superhard blade and is welded on the ball head knife cutter hub, has overcome the deficiency of common superhard rose cutter, and cutting resistance is diminished, and cutting temperature reduces, and cutting ratio is more steady.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of superhard rose cutter of welded type of curve sword.
The utility model is achieved in that
As shown in Figure 3, the utility model is made up of handle of a knife portion, cutting portion, and cutting portion is made up of superhard bulb blade of curve sword and cutting portion bulb; The superhard bulb blade of curve sword described in the utility model is a curved surface.
The superhard bulb blade of curve sword described in the utility model more specifically is an arc surface.
The superhard ball head knife sheet material of curve sword described in the utility model is CBN (cubic boron nitride).
The utlity model has following beneficial effect: when using curve angle of throat sheet to carry out machining, the same time has only part blade contact workpiece, and cutting resistance diminishes, cutting temperature reduces, and cutting ratio is more steady, and smear metal is easy to discharge, the surface quality of workpiece to be machined improves, and cutter life prolongs.
