A turning tool is a tool with a cutting part used for turning. Turning tools are one of the most widely used tools in cutting processing. As a type of cutting tool, turning tools have a very harsh working environment and need to withstand huge friction. Therefore, many manufacturers use ultrasonic induction heating equipment to heat treat turning tools.
The commonly used material for turning tools is B212, which is a W-series super-hard high-speed steel. It has the characteristics of high hardness, high thermal hardness and wear resistance. It can process hard and tough materials, such as ultra-high strength steel and other quenched structural steels, and can also cut difficult-to-machine materials, such as high-temperature alloys and iron. Aluminum-manganese heat-resistant steel and stainless steel, etc. It is particularly useful for processing metal materials with a hardness of 40-50HRC. The parts to be processed have high precision and low surface roughness.
The heat treatment process of the 10mmx10mmx200mm turning tool is: first use ultrasonic induction heating equipment to perform preheating heat treatment at 840-860℃x6min; then perform heating heat treatment at 1235-1245℃x3min, and finally air-cooling after neutral salt classification at 600℃x3min. The particle size is controlled at level 9.5-10. The first tempering is 580℃xlh, and then the tempering is 3 times at 55O℃xlhx. After tempering by ultrasonic induction annealing equipment, its hardness is 66-67HRC.
The heat treatment process has a great impact on the heat treatment quality of the workpiece. Therefore, it is very important to understand and master the heat treatment process of the workpiece. This article briefly introduces the ultrasonic heat treatment process of B212 steel turning tools. After many manufacturers adopt the above, the turning tools produced meet the requirements.
