上下双回旋螺旋刀组：

Up and down double spiral knife :

进口高级加工中心精密加工螺旋刀辊，经平衡调整，稳定性佳，裁切力小，克重负载高。

Imported advanced machining center precision processing spiral knife roller, balanced adjustment, good stability, small cutting force, high weight load

优质齿轮箱，使用无间隙设计齿轮，啮合噪音低，比传统齿轮箱寿命长一倍。

High quality gearbox with gearless design gears for low meshing noise and twice the life of conventional gearboxes.

球墨铸铁铸造而成的车壁和支撑件，经处理后，再由进口的大型立体加工中心加工而成，精度等级要求高，加工误差更小，整机的运行更稳定，可靠。

The body of machine and support members cast from ductile iron are processed and then processed by imported large-scale three-dimensional machining center. The precision level is high, the machining error is smaller, and the whole machine is more stable and reliable.

崭新的螺旋刀槽设计，配合进口优质钨钢刀，持久耐用，跳动小，精度高，裁切纸张无毛边。

The new spiral rolls design, combined with imported high-quality tungsten steel knives, is durable, high precision, and cuts paper without burrs.
