The machine utilizes a sophisticated floating clamping system for the web, driven by dual up-down jaws and powerful air-over-hydraulic boosters. This advanced mechanism allows the clamps to securely grip the steel while automatically compensating for the minor dimensional inconsistencies and warpages inherent in raw structural steel, ensuring accurate, parallel beveling without distorting the beam.
Maintenance is highly efficient and straightforward. The milling heads utilize cemented carbide indexable cutters. This means operators only need to rotate or replace the small carbide inserts when they become dull, rather than replacing the entire cutting tool. Regular lubrication of the spindle bearings and routine checks of the motor tension are recommended to maintain peak, chatter-free performance.
Yes. The PLC system features a highly adaptable touch-screen interface designed for rapid manual data entry directly from your engineering drawings. Operators simply input the target dimensions and angles, and the machine's longitudinal and transverse slipways automatically adjust to the correct positions. This drastically reduces setup time between different batches of steel.
Due to the machine's substantial weight (approximately 11 tons) and its overall footprint (7.0 × 4.0 × 2.8 meters), installation requires a reinforced, leveled concrete foundation capable of bearing heavy dynamic loads. Additionally, a stable three-phase four-wire 380V AC power supply and a clean, dry compressed air line to drive the hydraulic boosters must be routed to the installation site prior to commissioning.
All sensitive electronic components, including the PLC, frequency converters, and touch-screen interface, are housed in industrial-grade, sealed electrical cabinets. Furthermore, we exclusively utilize premium, globally recognized brands for these components, which are specifically engineered to withstand the temperature fluctuations, electrical noise, and airborne metallic particulates common in heavy steel manufacturing facilities.
