Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution:
the utility model provides a superhard diamond face milling blade for bimetal increases circular arc, including cutting part 1 and base body portion 2, cutting part 1 inlays and locates the one end department of base body portion 2, and with cutting part 1 and base body portion 2 welded fastening, cutting part 1 is kept away from the blade from the top down of base body portion 2 and is included first end milling part 101, second end milling part 102 and third end milling part 103, the blade of first end milling part 101 is the circular arc structure, the blade of third end milling part 103 is rectilinear structure, second end milling part 102 is located the crossing department of first end milling part 101 and third end milling part 103, and the blade of second end milling part 102 is the circular arc structure.
During the manufacturing process, the cutting portion of the milling cutter blade is made of polycrystalline diamond compact 104, which is suitable for processing bimetallic materials (such as CTM302 with mixed grain size), and the milling cutter blade is made of domestic hard alloy sheet 105 for supporting and fixing polycrystalline diamond compact 104.
In the manufacturing process of the milling cutter blade, the cutting blade is cut by adopting a slow wire process, the cut cutting edge is good, and the base body part 2 is ground by adopting a common tool grinding machine. The welding adopts a vacuum welding technology, the welding strength is higher, and the welding agent is Morgan soldering paste which is commonly used in the market. The vacuum welding technology is mature and the efficiency is high. RG9 equipment can be used in the blade grinding, and RG9 lathe is better in grinding precision itself, and blade quality is better, and the uniformity can both reach customer's processing requirement.
