Problems solved by technology

The tool obtained by this processing method is observed in a microscopic state. The surface of the carbide insert forms an uneven plane. At the same time, the carbide insert and the tool holder are not on the same plane. Such a surface affects the service life of the tool and the processing quality of the product. As well as the stability and consistency of the tool size, the center point of the tool must be readjusted every time the worker changes the tool during the production process, thereby reducing production efficiency and increasing the production cost of the enterprise

Embodiment Construction

[0031] As shown in the figure, the mirror-polished cemented carbide cutter involved in the present invention is composed of a cutter bar 1 and a cemented carbide blade 2, and cemented carbide is used as a raw material to manufacture the cemented carbide blade 2 in manufacture, and steel is used to manufacture The tool bar 1 of the cutter is welded on the tool bar 1 with a cemented carbide blade 2, and a welding metal layer 3 is formed between the tool bar 1 and the cemented carbide blade 2, and the hard alloy blade 2 and the above-mentioned tool bar 1 After grinding, at least one surface of the cemented carbide blade is on the same surface as the corresponding surface of the tool holder, and the surface roughness of the cemented carbide blade 2 is between 0.012um and 0.4um.

[0032] Firstly, the cemented carbide and steel are initially processed to produce various shapes of cemented carbide tool holder 1 and blade 2, and the mounting part is cut out at one end of the tool rod 1...

Abstract

The invention discloses a mirror finishing hard alloy cutter and the manufacture method. The cutter consists of a cutter rod and a hard alloy blade which is welded on the cutter rod. The invention is characterized in that after the hard alloy blade is grinded with the cutter rod, at least one hard alloy blade surface and a corresponding cutter rod surface are arranged on the same plane; after the hard alloy blade is grinded, the surface roughness is ranging from 0.012 Mu m to 0.4 Mu m. The invention has the advantages that one surface of the hard alloy blade is arranged on the same plane with one surface of the cutter rod, thus ensuring the stability and consistency of the dimension of the cutter; workers has no needs to re-adjust the central point of the cutter and improves production efficiency by directly arranging the cutter; the hard alloy blade has high-precision cutting surface, good processing performance, good chipping discharging effect, long service life, high processing precision and surface smoothness of the product; the quality of the product is obviously improved and the practicability is strong.

Description

[technical field] [0001] The invention relates to the field of tool manufacturing in the machining industry, in particular to a mirror-polished carbide tool and a manufacturing method thereof. [Background technique] [0002] Nowadays, precision metal machining controls the production cost and product quality. The quality of the tool is the primary condition. However, the traditional tool cannot meet the ever-changing market demand. Therefore, many manufacturers are constantly improving the material and production process of the tool. . [0003] Traditional knives, due to the poor finish of the blade, the tool wears quickly, the cutting edge of the tool is thick, the knife face and the surface of the workpiece are prone to severe friction, the cutting resistance is large, and the surface of the workpiece has serious scales, which affects the improvement of the finish and causes product quality. question. Therefore, it is necessary to improve the smoothness of the existing c...
