Product Description
As a leading manufacturer of industrial rolling machinery, we proudly present our advanced 4-Roll Plate Rolling Machine - the ultimate rolling-machine solution for sheet metal processing. Engineered with German hydraulic technology and CE-certified components, this equipment redefines precision, efficiency, and durability in metal fabrication.
Key Advantages of Our 4-Roll Rolling-Machine:
1.Precision Engineering
Dual CNC-controlled upper rolls + powered side rolls ensure ±0.1mm thickness accuracy
Automatic pre-bending function eliminates flat edges
360° symmetrical rolling capability for perfect cylindrical/conical shapes
2.Enhanced Productivity
40% faster operation than traditional 3-roll models
500kN maximum rolling force handles steel (up to 250mm thick), aluminum, and alloys
Touchscreen interface with 20+ preset programs for rapid job switching
3.Durability Guaranteed
Hardened alloy steel rolls (HRC 58-62) withstand 10,000+ operating hours
Reinforced frame structure (250MPa yield strength) prevents deformation
IP54 protection rating for harsh workshop environments
4.Energy-Smart Design
Variable-frequency drive reduces power consumption by 30%
Closed-loop hydraulic system minimizes oil temperature rise (<45°C)
Automatic sleep mode cuts idle energy waste
