The control system incorporates the SIEMENS 828D CNC system, with servo motor-driven feeding. This configuration delivers high operational efficiency and ensures consistent workpiece precision. A servo-centered centering device is mounted on the feeding support roller, enabling it to accommodate the processing of variable-cross-section plates with a height difference ranging from 0 to 200mm.
The exhibition features a curated selection of finished longitudinal beam samples processed by this production line, covering a variety of specifications applicable to mining trucks and special-purpose vehicles. These samples vividly demonstrate the precise hole positioning, smooth punched edges, and overall structural stability achieved through the equipment.
This equipment is a custom-developed solution specifically engineered for the punching process of flat automotive longitudinal beams. It is primarily designed to machine the main beams of trucks and special-purpose vehicles, guaranteeing precise hole fabrication to fulfill the structural assembly requirements of these heavy-duty and custom-made automotive load-bearing components.
