高精度的端部预弯：端部预弯时，能够自由地设定直边长度，上辊压下，在压力下，实行高精度的端部预弯。
根据用途，有以下控制方法：
TNC(上NC)：多品种小量生产用
T& BNC(上下NC)：少品种大量生产用
CNC(CNC)：多品种大量生产用

End prebending of high precision
High Accurate End PreBending when bending the end ,it can freely set the length of the edge .Top roller
presses down ,and high accurate end
prebending is done under a certainpressure.  

制品精度超群：由于连续弯曲，以及高精度的端部弯曲，从而得到精度超群的制品；另外上辊呈鼓形状，托辊配合调节，从薄板到厚板这一广泛的范围内能够卷制理想的产品。

丰富的弯曲形状
具有卷制O型、U型、多段R等不同的形状，其方式：
O型变曲：后方弯曲方式
U型变曲：前方弯曲方式
弯曲：组合式方式
NC contol high producing efficiency NC controls High Production Efficiency One operator , simple operation
,and high efficiency.

NC控制高的生产效率：
一人作业，操作简单，效率大幅度提高。
Different uses with coordinating methods
Three are following controlling methods accrding to its use.
TNC (Top NC):for many types but small quantity of production：
T & BAC (Top and bottom NC )：for few types but large quantity of production：
CNC（CNC）：for many types but large quantity of production.
Excellect product precision
Products Have Superior precision Due to continuous bending and high accurate and pre-bending, As the top roller is in the shape of drum, with the supporting roller adjusted , it can coil ideal
products in the wide range from sheets to plates.
