Referring to fig. 1 and 2, an embodiment of the present invention provides a PCD end mill and a processing method thereof, where the processing method of the PCD end mill specifically includes:
Step S1, welding the PCD blank 10a on one end of the hard alloy bar 20 to obtain a cutter blank.
Wherein, the PCD blank 10a is obtained by cutting from a PCD composite sheet by means of electric spark cutting, one PCD composite sheet can be cut to obtain a plurality of PCD blanks 10a, and the diameter of the PCD blank 10a in the embodiment is 2mm; the hard alloy bar 20 is made of tungsten-cobalt hard alloy, tungsten-titanium-cobalt hard alloy or tungsten-titanium-tantalum hard alloy; as shown in fig. 3, a PCD blank 10a is selected, a brazing 30 is disposed between the PCD blank 10a and the cemented carbide bar 20, and then the PCD blank 10a and the cemented carbide bar 20 are welded together by a vacuum welder through high temperature, heat preservation, temperature reduction and other processes, thereby forming a cutter blank. Preferably, the PCD blank 10a is a cylindrical structure having a diameter that is 1-2 mm greater than the diameter of the cutter shape.
And S2, machining the end face and the outer circle of the cutter blank in an electric spark cutting mode to obtain a cutter semi-finished product.
The method aims to reduce the removal amount of laser processing, improve the processing efficiency and reduce the processing cost, so that the welded cutter blanks are pretreated in an electric spark cutting mode. Specifically, as shown in fig. 4, the cutter blank is mounted on a rotating shaft of a wire electric discharge machine, electric discharge machining is performed by using a galvanized wire of 0.1mm, the rotating speed of the rotating shaft is set to 80-120 rpm, and the cutting speed is set to 1-3 mm/min, so that the electric discharge wire cuts the cutter blank along the line shown in fig. 4.
Since the spark cutting of the PCD material generates a surface reaction layer, the spark cutting of the PCD blank 10a includes rough machining, semi-finishing and finishing in order to reduce the surface reaction layer, and the rough machining voltage is 50 to 60V, the semi-finishing voltage is 30 to 40V, the finishing voltage is 20 to 30V, and the machining speed is set to 2mm/min.
In this embodiment, the handle portion (i.e. the cemented carbide bar 20 portion) of the final PCD end mill is taken as an example of a taper neck structure, the shape structure of the tool blank after electric spark cutting treatment is shown in fig. 5, and the parameters of the obtained tool semi-finished product are: the diameter of the cylinder of the PCD blank 10a is 1.1mm, the thickness is 0.35mm, the diameter of the neck of the hard alloy bar 20 connected with the PCD blank 10a is 0.9mm, and the effective edge length is 2mm.
And S3, carrying out laser processing on the PCD blank 10a on the cutter semi-finished product according to the required cutter shape to obtain the finished PCD end mill.
Specifically, the PCD blank 10a is laser processed by a laser processing apparatus according to the present embodiment, and the laser processing apparatus may employ a nanosecond, picosecond or femtosecond laser apparatus according to actual requirements.
By adopting the processing method, the cutter blank is firstly subjected to reducing processing by utilizing the electric spark through adopting the combined technology of electric spark cutting and laser processing, then the PCD blank 10a is processed in a laser processing mode according to the design of the cutter appearance, the advantages of high electric spark cutting speed and high laser processing precision are fully utilized, the defects that the processing time is long and the grinding wheel is easy to wear in the diamond grinding processing mode in the prior art are overcome, and the production cost is reduced while the processing efficiency is greatly improved.

As shown in fig. 5, in the laser thinning process of the cutter, the PCD blank 10a is processed by using a laser beam to remove the portion of the PCD blank 10a, which may interfere with each other during the actual cutting process, so that a clearance portion 11 is formed at the rear side of each blade opposite to the rake face 12, thereby ensuring smooth cutting of the PCD end mill. Since the clearance portion 11 does not participate in the cutting action of the tool, efficiency is dominant when the clearance portion 11 is processed by laser, and laser processing parameters can be set as: the laser power is 80-100W, the scanning speed is 1-2 mm/s, the scanning depth is 0.01-0.02 mm, and the laser spot spacing is 0.02mm, so that the processing efficiency in the process of producing the cutter is further improved.

As shown in fig. 8, for the back face processing flow of the cutter, the semi-finished product of the cutter is adjusted to be at a horizontal position, the rotating shaft is rotated to make the included angle between the front face 12 of the semi-finished product of the cutter and the XY axis plane be 10 degrees, meanwhile, the rotating shaft is adjusted to make the preferred included angle between the central axis of the semi-finished product of the cutter and the X axis be 10 degrees, so that the laser beam starts to cut along the edge of the PCD blank 10a from the center of the top face, thereby forming end edge first back face 14 and Zhou Rendi, and end edge first back face 14 and Zhou Rendi and back face 15 form arc transition, the radius of the round angle is 0.1mm, and the included angle between the front face 12 and the end edge first back face 14 and Zhou Rendi and back face 15 is 80 degrees; then, the rotation shaft is rotated to make the included angle between the front cutter face 12 of the semi-finished cutter and the XY axis plane be 30 degrees, and the rotation shaft is adjusted to make the preferable included angle between the central axis of the semi-finished cutter and the X axis be 30 degrees, so that the laser beam starts to cut along the edge of the PCD blank 10a from the center of the top surface of the PCD blank 10a again, thereby forming an end edge second rear cutter face 16 connected with the end edge first rear cutter face 14 and Zhou Rendi rear cutter edges 17 connected with the Zhou Rendi first rear cutter face 15, and the included angles between the front cutter face 12 and the end edge second rear cutter faces 16 and Zhou Rendi rear cutter faces 17 are 60 degrees.

Since the surface quality of the rake face 12 has a great influence on the tool performance, it is necessary to treat the rake face 12 with smaller laser processing parameters after the processing is completed, and the laser power is generally less than 20W. Of course, in other embodiments, the cutting or edge restoration of the rake face 12 by the diamond wheel may be performed simultaneously.
Preferably, the laser rough machining and the laser finish machining are included in the machining of the front cutter surface 12 and the machining of the rear cutter surface, the laser power adopted by the laser rough machining is larger than the laser power adopted by the laser finish machining, the machining allowance of the laser rough machining is larger than the machining allowance of the laser finish machining, the laser power of the laser rough machining is 60-80W, the power of the laser finish machining is 30-40W, and the scanning depth of each layer is 0.01mm.
