The processing difficulty of molybdenum electrode is relatively high, mainly because molybdenum has the characteristics of high melting point, high hardness and brittleness. The following are some considerations in molybdenum electrode machining:
High melting point: Molybdenum has a very high melting point of about 2620°C. Therefore, when processing molybdenum electrodes, it is necessary to use high-temperature processing processes and equipment, such as high-temperature furnaces and thermal processing processes, to ensure that the material can achieve the desired shape and size.
High hardness: Molybdenum has high hardness, which makes molybdenum electrodes challenge traditional processing methods (such as cutting and drilling). During machining, carbide tools and specialized cutting techniques may be required to achieve the desired machining accuracy and surface quality.
Brittleness: Molybdenum material is relatively brittle and prone to fracture and breakage. During the processing, it is necessary to pay attention to reducing stress concentration, controlling the processing force, and selecting appropriate cutting parameters to avoid cracks and damage.
Due to the poor processing performance of molybdenum, it is usually necessary to use professional processing equipment and techniques, such as precision cutting, grinding and EDM, to ensure that the molybdenum electrode can achieve the required shape, size and surface quality.
