We all know that there are many types of cutting tools, so we can also see many cutting tools wholesale around us. Cutting tools have relatively high hardness requirements for materials.
High-hardness workpiece materials must be processed with higher hardness tools. The hardness of the tool material must be higher than the hardness of the workpiece material, and it is generally required to be above 60HRC. The higher the hardness of the tool material, the better its wear resistance. For example, when the cobalt content in the cemented carbide increases, its strength and toughness increase, and the hardness decreases, which is suitable for rough machining; when the cobalt content decreases, its hardness and wear resistance increase, and it is suitable for finishing machining. The metal processing is really good.
Tools with excellent high-temperature mechanical properties are especially suitable for high-speed cutting. The excellent high-temperature performance of ceramic tools enables them to be cut at a high speed, and the allowable cutting speed can be increased by 2 to 10 times compared with cemented carbide.
Cutting tools have hardness requirements, so threading tools naturally have their requirements, so we must pay attention to them.
