The processing category "over 500kg" primarily refers to the manufacturing of large components and heavy structures. In this field, addressing difficulties in handling and fixturing due to the workpiece's mass, as well as countermeasures against deformation caused by self-weight and thermal expansion during processing, become extremely critical. To ensure the required machining accuracy, highly rigid large-scale machine tools (such as gantry machining centers, large NC lathes, and large grinding machines), special jigs, and temperature control systems are indispensable. Typical applications include frames for construction machinery, marine engine components, power generation equipment, large molds, and aerospace parts, all of which are crucial elements supporting the quality and performance of core industries.
