Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing tools, in particular to a wear-resistant tungsten steel hard alloy tool. Background Art

[0002] Machining tools are tools used for cutting, milling and other processing of metal workpieces. Currently, common tool materials are tungsten steel, cemented carbide and ceramic materials.

[0003] The existing technical disclosure number CN220782274U patent document provides a wear-resistant tungsten steel carbide tool. The wear-resistant tungsten steel carbide tool is configured by arranging a plurality of rotatable cutting blades on a rotating tool holder. When processing a workpiece, the rotating tool holder drives the plurality of cutting blades to revolve, and the cutting blades themselves can rotate around a locking screw. Thus, during the processing, the cutting blades can continuously change the cutting edge position, thereby meeting the processing requirements and avoiding long-term overheating damage to the cutting edges of the cutting blades.

[0004] However, the existing wear-resistant tungsten carbide cutting tools have poor corrosion resistance and rust resistance when in use. Since tungsten carbide contains a large amount of carbon elements, chemical reactions are prone to occur in high temperature and humid environments, resulting in the reduction of iron ions and the inability to form a stable protective layer. Therefore, when tungsten carbide cutting tools are used in high temperature and humid environments for a long time, the tungsten carbide alloy structure is prone to oxidation reactions, resulting in surface rust. Once the tungsten carbide cutting tools are rusted, problems such as surface roughness and oxide accumulation will occur, which will directly affect the stability and service life of the tungsten carbide cutting tools.
