The general process and process:
---computer design
--- CNC cutting (manganese plate)
--- bending machine bending and shaping (horse head part)
--- professional technician welding
--- large boring machine boring
--- lengthening Arm base and pipeline installation
--- bucket cylinder installation
--- anti-stress test
--- product shot blasting treatment
--- high-temperature spraying
--- detailed inspection before leaving the factory
--- qualified delivery

Generally speaking, a computer 3D-aided design system is used for stress analysis and simulation actions. In addition, the processing equipment, the proficiency of employees skills and practical application knowledge, experience, material selection, and manufacturing process are all related to the structural strength and use of the excavators extended arm. Performance and quality have a critical impact.
