Abstract
The invention discloses a method and structure for improving the cutting surface roughness of a hard alloy end mill. In the invention, a small-plane blade is manufactured on the end edge at the front end of the hard alloy end mill, wherein the length of the small-plane blade is 0.2-0.3mm, and the side clearance angle of the small-plane blade is 0; and by adopting the small-plane blade, the end surface cutting points are increased during the cutting processing of the hard alloy end mill, thus the precision of the surface roughness of the cut processing workpiece is improved. Through the invention, the processing precision is high, and the processed workpiece has good surface fineness; and the structure disclosed by the invention has the advantages of long service life, simplicity, low using cost and the like, and is easy to manufacture.
Description
Technical field
the present invention relates to a kind of method and structure that improves the carbide end mill cutting surface roughness, belong to the slotting cutter manufacture technology field.
Background technology
are present; Generally all be provided with the end sword on the leading section of carbide end mill in the prior art; And its end sword all is provided with certain side clearance, and (promptly edge plane and the horizontal plane when the axis normal of slotting cutter end sword during in horizontal plane has certain included angle; That is to say that the end sword is not orthogonal to the axis of slotting cutter); This carbide end mill that is provided with side clearance end sword, the precision of surface roughness that mainly exists the workpiece of being processed in use is lower, and its surface of the work that processes is more coarse; Often can see tangible processing tool marks, the accuracy class of the roughness of the workpiece that it processes generally can only reach Ra3.2～Ra6.3.Therefore, the result of use of existing carbide end mill still is not ideal enough.
Summary of the invention
the objective of the invention is, and a kind of method and structure that improves the carbide end mill cutting surface roughness is provided, and improving the precision and the surface smoothness of carbide end mill processing work, thereby overcome the deficiency of prior art.
the present invention is achieved in that a kind of method that improves the carbide end mill cutting surface roughness of the present invention is; On the end sword of carbide end mill leading section, making a segment length is that 0.2～0.3mm and side clearance are 0 facet blade; Increase the building up by welding point of carbide end mill when the cut through this facet blade, thereby improve the precision of the surface roughness that is cut processing work.
according to of the present invention a kind of structure that improves the carbide end mill cutting surface roughness that said method makes up are: this structure comprises the carbide end mill that is provided with the end sword; On the end sword of carbide end mill, be provided with the facet blade; The length of this facet blade is 0.2～0.3mm, and the axis normal of the edge plane of this facet blade and carbide end mill.
are owing to adopted technique scheme; The present invention has increased by one section 0.2～0.3mm facet blade on the end sword of the front end face of existing carbide end mill; This facet blade is perpendicular to the axis (promptly this facet blade is not with side clearance) of carbide end mill; Through test and the actual proof of using; The design of this facet blade neither influences the serviceability of former cutter, also can not influence the production efficiency of cutter, but can improve the end sword cutting surface quality of end mill tool.The present invention has increased the building up by welding point of slotting cutter, and the present invention adds man-hour in actual cut, is with contact of facet blade and cutting surface to be machined, has avoided traditional carbide end mill because point or the line surface roughness that point contacts, the some cutting is caused.Through test, adopt carbide end mill of the present invention can process the workpiece that surface roughness is Ra0.32～Ra0.4 precision.So, the present invention compared with prior art, the good advantage of workpiece surface finish that the present invention not only has the machining accuracy height, processes, and the present invention also have long service life, simple in structure, make easily, advantage such as use cost is low.

description of reference numerals: the 1-carbide end mill, 2-holds sword, 3-facet blade, the length of L-facet blade.
The specific embodiment
are done further detailed description below in conjunction with accompanying drawing and embodiment to the present invention.
embodiments of the invention: a kind of method that improves the carbide end mill cutting surface roughness of the present invention is on the basis of existing carbide end mill, to implement; This method is by traditional method processing rigid alloy slotting cutter the time; When making the end sword of carbide end mill leading section; On the end sword of carbide end mill leading section, making a segment length simultaneously is that 0.2～0.3mm and side clearance are 0 facet blade; Increase the building up by welding point of carbide end mill when the cut through this facet blade, thereby improve the precision of the surface roughness that is cut processing work.
A kind of structure that improves the carbide end mill cutting surface roughness that
make up according to the method for the invention; Like Fig. 1～shown in Figure 3; This structure comprises the carbide end mill 1 that is provided with end sword 2; On each end sword 2 of carbide end mill 1, all produce one section facet blade 3; The length L of the facet blade 3 on each end sword 2 all is controlled at the scope of 0.2～0.3mm, makes the axis normal of edge plane and the carbide end mill 1 of each facet blade 3 simultaneously.
