Key Features of the 4-12 Automatic Steel Bar Bending Machine
- Eco-Friendly Operation:
Powered by a servo motor system, the machine operates quietly and cleanly, eliminating pollution and ensuring environmental safety. - Precision Monitoring:
Equipped with two high-precision sensors, it guarantees reliable performance by accurately monitoring bending and extension movements. - Energy Efficiency:
Unlike pneumatic systems, it avoids air pump and cylinder noise, cutting power consumption by up to 2 kW per hour and reducing maintenance time. - Enhanced Durability:
The split-type fixed knife design simplifies maintenance. Both sides of the fixed cutter are usable, prolonging its life span, while the four-sided movable cutter design increases durability by four times, lowering overall maintenance costs.
