Abstract
The invention relates to a process for machining a drill bit or a milling cutter, which comprises the following steps of: A) selecting a cutter blank material and cutting the blank material into a cutter blank with a set length; B) machining technical tops on the two end parts of the cutter blank; C) grinding the outer diameter of the cutter blank to allow the outer diameter of the cutter blank to reach a set value; D) coarsely grinding the cutter blank to form a discharge chute; and E) polishing the discharge chute with an accurate grinding wheel, wherein the polishing precision is 0.1 micron. The process obtains the discharge chute with a very smooth surface by adding a polishing procedure, so the machining process can decrease the friction force of cut chips so as to quickly discharge the cut chips and can decrease the cut chips attached to the front cutter surface so as to improve the machining accuracy of the cutter.
Description
Technical field
The present invention relates to a kind of processing technology of metal cutting tool, particularly as being formed with the processing technology of the cutter of chip curl discharge groove on the external peripheral surfaces such as drill bit or milling cutter.
Background technology
Existing drill bit and end mill(ing) cutter all have the rotating tool body usually, the periphery of cutter body offers the discharge groove that is used to discharge smear metal along the hand of spiral, usually the discharge groove of these drill bits or milling cutter all is by forming through roughly grinding or roughly grind and partly finish grinding twice grinding on universal machine, usually the surface smoothness of this discharge groove is all relatively poor, add man-hour boring to mill, can produce high temperature at cutting zone, borings is piled up easily under high temperature and high pressure or is bonded at tool surface, be not easy rapid discharge, also can influence the machining accuracy of cutter simultaneously.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can make machining accuracy height, the technology of the drill bit of discharge or milling cutter rapidly again simultaneously.
The technical solution adopted in the present invention is: the processing technology of a kind of drill bit or milling cutter comprises the steps:
A), choose the cutter blank, described blank is cut the cutter blank that forms preseting length;
B), top in the both ends of described cutter blank processing technology;
C), the external diameter of described cutter blank is carried out grinding, make the outside dimension of described cutter blank reach setting value;
D), the described discharge groove of corase grind shaping on described cutter blank;
E), utilize finishing wheel that described discharge groove is polished.
Further, in the described step e, the polishing precision of discharge groove is 0.1 micron.
Preferably, between described step D and step e, described discharge groove is carried out half correct grinding.
Advantage of the present invention is: increased in traditional processing technology discharge groove is carried out step of polishing, very smooth through the surface of polishing the discharge groove of processing, therefore can reduce the frictional force of cutting swarf, thereby cutting swarf is discharged fast, reduce simultaneously attached to the cutting swarf on the rake face, thus the machining accuracy of raising cutter.
Description of drawings
Accompanying drawing 1 is a process chart of the present invention.
Accompanying drawing 2 is the front view of the milling cutter that adopts processing method of the present invention and obtain;
The specific embodiment
The invention discloses a kind of processing technology of utilizing universal machine to make drill bit or milling cutter, comprise the steps:
A), choose the carbide alloy blank, described blank is cut the cutter blank that forms preseting length;
B), top in the both ends of described cutter blank processing technology;
C), on cylindrical grinder, the external diameter of described cutter blank is successively roughly ground and finish grinded, make the outside dimension of described cutter blank reach setting value;
D), in universal machine, described cutter blank is roughly ground, forming many discharge grooves, and described many discharge grooves are carried out half correct grinding respectively;
E), then, utilize finishing wheel that described discharge groove is polished, 0.1 micron of polishing precision.
Can process drill bit or milling cutter through above-mentioned processing technology, with the milling cutter is example, it is the cylindrical revolution body at center that this milling cutter has with the axial line, one end of described body forms shank 1, the other end forms cutting portion 2, offer the main cutting edge 3 that extends along the hand of spiral on the external peripheral surface of described cutting portion 2, be formed with discharge groove 4 between two adjacent main cutting edges 3, described discharge groove 4 forms rake face in the side towards the cutter direction of rotation, the surface of discharge groove 4 is a burnishing surface, surface smoothness is 0.1 micron, therefore can reduce the friction of cutting swarf and discharge groove 4, impel cutting swarf to quicken to discharge.
