The chassis system integration of new energy vehicles has been significantly improved, and CNC machining centers have shown unique advantages in the manufacturing of key components such as subframes and battery trays. The 6061-T6 aluminum alloy control arm used in Tesla's integrated die-cast body is precisely processed with a topology optimized structure through a high-speed CNC milling center, achieving a 35% weight reduction while maintaining a tensile strength of 520MPa. The Bosch electronic steering gear housing uses a vertical machining center with a compound angle milling head, which can complete the entire process of processing including the worm gear cavity and sensor mounting surface at 18 stations, with a position toleranc.
CNC machining centers play a key role in multiple industries with their high precision, high efficiency and versatility. The following are its main application areas and typical cases:
1. Automobile manufacturing industry
