Abstract
The invention relates to a machining method of a cutter. The method comprises the following steps: the method comprises the following steps: cutting two mutually perpendicular cutting surfaces at the end part of the hard alloy substrate, wherein the cutting surface parallel to the bottom of the hard alloy substrate and the hard alloy substrate form a welding platform, the other cutting surface is a welding surface, a chip groove is formed on the welding platform, a positioning surface is reserved on one side of the chip groove close to the welding surface, and finally a clearance surface in the shape of an inwards concave arc surface is formed on one side of the protruding part of the end part of the hard alloy substrate, which is far away from the welding surface; secondly, welding the diamond on the end part of the hard alloy substrate to form a diamond cutter; and thirdly, machining the cutter by adopting a laser cutting method to enable the cutter to be provided with a first rear cutter face, a second rear cutter face and a cutter cutting edge. The process method of the invention is simple, the processing precision is high, and the coating is coated on the surface of the diamond, thereby effectively preventing the transmission and reflection of laser and improving the processing efficiency and quality of the cutter.
Description
Technical Field
The invention relates to a machining method of a cutter.
Background
Diamond is a crystal of a single carbon atom, and has the highest hardness, rigidity, refractive index and thermal conductivity in nature. Can meet most requirements of precision and ultra-precision cutting on cutter materials, and is an ideal precision cutting cutter material. When the diamond cutter is manufactured by adopting the traditional mechanical grinding method, because the grinding linear velocity is high, the local pressure is large, the impact on the surface and the cutting edge of the cutter is severe, the surface of the cutter can generate tiny furrows and thicker processing deterioration layers inevitably, and the saw teeth of the cutting edge are larger, thereby limiting the further improvement of the quality of the cutter.
Disclosure of Invention
Aiming at the defects, the invention aims to provide a machining method of a cutter, which has the advantages of simple process method, high machining precision and good quality.
Therefore, the technical scheme adopted by the invention is as follows:
the method comprises the following steps:
the method comprises the following steps: cutting two mutually perpendicular cutting surfaces at the end part of the hard alloy substrate, wherein the cutting surface parallel to the bottom of the hard alloy substrate and the hard alloy substrate form a welding platform, the other cutting surface is a welding surface, a chip groove is formed on the welding platform, a positioning surface is reserved on one side of the chip groove close to the welding surface, and finally a clearance surface in the shape of an inwards concave arc surface is formed on one side of the protruding part of the end part of the hard alloy substrate, which is far away from the welding surface;
secondly, welding the diamond on the end part of the hard alloy substrate to form a diamond cutter;
and thirdly, machining the cutter by adopting a laser cutting method to enable the cutter to be provided with a first rear cutter face, a second rear cutter face and a cutter cutting edge.
As a further improvement of the technical scheme, before the processing, the surface of the diamond cutter is cleaned by steam.
As a further improvement of the technical scheme, the surface of the diamond is coated with a coating.
The invention has the advantages that:
the process method of the invention is simple, the processing precision is high, and the coating is coated on the surface of the diamond, thereby effectively preventing the transmission and reflection of laser and improving the processing efficiency and quality of the cutter.
