Molybdenum is a metal element, with high temperature oxidation resistance, high melting point, high hardness and other characteristics, so its processing performance is good. The following will introduce its machining performance from the aspects of easy machinability, cold machinability and hot machinability.
1. Processing performance
(1) Easy machinability: molybdenum cutting is relatively easy, because its hardness is moderate, and it is not easy to produce rebound phenomenon when cutting.
(2) cold workability: molybdenum at room temperature, hardness and elasticity are better, can be stretched, stamping and other cold processing, but need to pay attention to, because the melting point of molybdenum is higher, so in the cold processing need to control the processing temperature, otherwise prone to fracture and other problems.
(3) hot processability: Molybdenum has good high temperature resistance and can be used for high temperature hot processing, such as hot rolling, hot extrusion, hot drawing, etc., but attention needs to be paid to controlling the processing temperature and speed to ensure the quality of processing.
2. Processing method
There are many kinds of processing methods of molybdenum, the following introduces several commonly used:
(1) Tungsten EDM method: tungsten EDM method is a precision machining method, which can be precision machining of molybdenum, and has the advantages of high processing precision and small area.
(2) Tungsten steel tool cutting method: Tungsten steel tool is a high hardness, high strength tool, can be cut molybdenum processing.
(3) Rolling method: rolling method is a high-strength processing method, which can process molybdenum at high speed and extreme pressure, which can speed up production efficiency.
Molybdenum is an important metal material, widely used in electronics, aviation, aerospace, chemical and other fields. When processing molybdenum, it is necessary to choose according to different processing methods and processing conditions to ensure processing quality and efficiency.
