In order to achieve the above purpose, the purpose of the present invention is achieved by the following technical solutions:
the utility model provides a miniature internal diameter lathe tool of PCBN, wherein, including the carbide cutter body, the one end of carbide cutter body is the tool bit, the tool bit includes outside cutting edge and internal connection body, outside cutting edge passes through internal connection body is fixed on the carbide cutter body, internal connection body contains the PCBN material.
The PCBN micro inner diameter turning tool is characterized in that the inner connector is combined with the hard alloy tool body through vacuum welding.
The PCBN miniature inner diameter turning tool is characterized in that the part of the hard alloy tool body connected with the internal connecting body is conical.
Above-mentioned miniature internal diameter lathe tool of PCBN, wherein, internal connection body is the cylinder stick.
Above-mentioned miniature internal diameter lathe tool of PCBN, wherein, outside cutting edge adopts the PCBN material to make.
The utility model discloses technical scheme's beneficial effect is:
the PCBN micro inside diameter lathe tool is used for solving the problems of quenched steel (more than HRC 45), cast iron and other materials
The PCBN material is used as the cutting edge, so that the size precision and the surface roughness of the micro inner diameter can be improved, and the machining life can be prolonged;
the PCBN material and the cylindrical rod are combined at high temperature and high pressure, and compared with welding, the combination strength is higher, so that the generation of tipping and tool bit separation in the cutting process is avoided;
the cylindrical rod with the PCBN material is combined with the hard alloy cutter body through vacuum welding, and the welding strength can be effectively improved due to the large welding area.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
Referring to fig. 1 and 2, the utility model discloses the miniature internal diameter lathe tool of PCBN includes carbide cutter body 1, and the one end of carbide cutter body 1 is the tool bit, and the tool bit includes outside cutting edge 2 and internal connection body 3, and outside cutting edge 2 passes through internal connection body 3 to be fixed on carbide cutter body 1, and internal connection body 3 contains the PCBN material.
In this embodiment, the internal connection body 3 is combined with the cemented carbide tool body 1 by vacuum welding, and the portion 11 of the cemented carbide tool body 1 connected with the internal connection body 3 is conical. The interconnector 3 is a cylindrical rod. The outer cutting edge 2 is made of PCBN materials, and the polycrystalline cubic boron nitride PCBN is a novel superhard cutter cutting material which is artificially synthesized after the artificial diamond, and the hardness of the novel superhard cutter cutting material is second to that of the diamond.
The PCBN miniature inside diameter lathe tool is used for solving the problems of materials such as quenched steel (more than HRC 45), cast iron and the like
The difficulty in turning the micro inner diameter workpiece is that the PCBN material is used as the cutting edge, so that the size precision, the surface roughness and the machining service life of the micro inner diameter can be improved. PCBN material and the cylindrical rod are combined through high temperature and high pressure, and compared with welding, the PCBN material and the cylindrical rod are higher in bonding strength, so that the generation of broken edges and tool bit separation in the cutting process is avoided; the cylindrical rod with the PCBN material is combined with the hard alloy cutter body through vacuum welding, and the welding strength can be effectively improved through a large welding area.
The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
