Our company:
![]() | Slitting cutting avoid defect of flame cutting use slitting cutting avoid most of the defect of traditional flame cutting, such as edge defect, edge unevenness, unsmooth,crack,roughness, dregs,crack etc |
Laser cutting greatly improves the cutting accuracy and quality,also will greatly avoid the deformation of some components and the generation of welding porosity | |
3D H beam drilling machine adopts 3D H beam driling machine, which can realize H beam web & flange drilling in three directions at once,this strongly improve the precision of hole making |
