龙门式数控火焰切割机是中工智能研制的代表机型，与台式切割机相比,该机型可不受固定工作台面的限制,可根据用户要求任意延长纵向机器行程,有效切割长度不受限制。有效切割宽度可达2-15m.该机型采用多火焰切割系统。火焰切割主要对6.0mm以上的碳钢板材进行火焰穿孔切割,切口垂直度好，边缘切割厚度可达300mm或更大。另外,可搭载各种型号的等离子切割系统,对6-50mm以内的不锈钢、碳钢及各种合金钢板材进行高品质下料。

       Gantry type numerical control flame cutting machine is a representative model developed by ZG-AUTO. Compared with the bench type cutting machine, this model can not be limited by the fixed worktable, can arbitrarily extend the longitudinal machine stroke according to the user's requirements, and the effective cutting length is not limited. The effective cutting width can reach 2-15m. The machine adopts multi flame cutting system. Flame cutting is mainly used to cut the carbon steel plate above 6.0mm with good perpendicularity and edge cutting thickness of 300 mm or more. In addition, it can be equipped with various types of plasma cutting system to cut stainless steel, carbon steel and various alloy steel plates within 6-50mm with high quality.
