FAQ FRO ANGLE STRAIGHTENING MACHINE

A  Beam end facing machine is for milling end face of beam in steel structure and ship building industry. Same as plate edge milling machine, for best milling quality& efficiency, we improved machine design to better level: Different from the general used milling head of 5.5kW and welded rail in industry, we adopt milling head of 7.5kW/11kW and high-precision ball bearing linear guideway, making milling process more efficient and good quality, while maintain the same level of machine price.
At the same time, we have superior technology in design and manufacture heavy-duty end facing machine. Same as high rise building, increase in size& loading capacity for facing machine poses great challenge to machine manufacturer, and we overcome the difficulty thanks to our rich experience and advanced technology.
In 2011, we designed and made the ever largest end facing machine of DX4080 (for beam cross section size up to 4*8m) successfully for a domestic ship-building customer and had very positive feedback from them.

A Turning roll/ Positioner/ Manipulator is the most common type of welding equipment for pipe/tank/vessel/structure member. These 3 kinds of equipment can be used individually, or integrally as welding center. With years of development, these products have very mature technology and sees trend of homogenization.
On the other hand, there is no end to meet customer requirement and chase technology advancement. With years of explore, we are not only very good at manufacturing standard products of welding equipment, but also combining optional unit such as Robot control/ Welding seam tracer, etc. to have flexible application.
Meanwhile, we also design and produce series of special purpose welding equipment, the list includes these products but not limited to: Hobbing Cutter/ Rolling boring machine/ Roller Strap Cladding machine/ Internal Longitudinal Welding machine of large Pipe Tank Tube/ Longitudinal Seam Welding machine/ Pipe Tube Flange Welding machine/ Small Flange Welding Equipment/ Cylinder Body Circumferential Welding Equipment, etc.
