★ High precision end pre bending: During end pre bending, the straight edge length can be freely set, and the upper roller can press down to achieve high-precision end pre bending under a certain pressure.
★ Superior product accuracy: Due to continuous bending and high-precision end pre bending, products with superior accuracy are obtained. In addition, the upper roller is in a drum shape, and the support roller is adjusted in coordination to roll ideal products from thin to thick plates in a wide range.
Different control methods for different purposes: According to the purpose, there are the following control methods:
TNC (Upper NC), multi variety and small-scale production.
T&BNC (upper and lower NC), used for mass production with few varieties.
CNC（CNC）， Multiple varieties for mass production.
★ High production efficiency controlled by CNC: One person operation, simple operation, greatly improves efficiency.
★ Rich bending shapes: available in various shapes such as rolled O-shaped, U-shaped, and multi segment R, with the following methods:
O-shaped bending: Rear bending method.
U-shaped bending: forward bending method.
Special bending: combined method.
