1) In the first photo is a set of DX5080 large Steel Structure End Milling Machine at customer site;
2) There were several operators working on the machine climbing the ladder for getting access;
3) In this product section, we will have a short discussion on such Heavy duty End Face Milling Machine.
1) Is a Shipbuilding Facility in South Central of China;
2) In a Shipbuilding facility, first metal plates need to be trimmed with Edge Rounding Machine; Then made into WIP (Working in process) of Stiffener Elements, and got straightened with Stiffener Plate Element Straightening Machine, then produced into final products of large ship;
2. Besides Shipbuilding, other industries that have demand on such large Welding Structure End Face Milling Machine are Bridge Construction (Such as Bay Bridge. Please check the product section of “Super Large Beam Hang Four Heads FXBJ-23 Edge Milling Machine” we produced for such project), Boiler Manufacture, Port Machinery, etc.;
1) The largest one we have made up to now, in the DX series Welding Structure End Face Milling Machine, is a set of DX6080 Large Structure Member End Milling Machine exported to Vietnam in 2018;
2) Hoisting of its column and machine bed, as well as erection at customer site, please see the second and third photos;
1) In general, there is not a lot of demand on such Large H Beam End Face Milling Machine in the market (Refers to vertical end face milling stroke of 4m and above, such as DX40xx/ DX50xx /DX60xx…), accounting for 5~10% at most with estimation;
2) Meanwhile, of course, the grand size of the H Beam End Face Milling Machine usually poses deep impression on people going around it, and the capability of designing/ processing/ manufacturing such Large Steel Structure End Milling Machine usually reflects general strength of a company.
As we mentioned in former product section, 3m valid vertical stroke is the entry level of Large H Beam End Face Milling Machine. The most applied models fall within the scope of 3~ 3.5m vertical stroke, such as DX3030/ DX3535… etc. When the vertical end facing stroke goes to 4m and above, the machine is special made and involves special attention on its order to delivery process. Here we give several points as below:
The foremost one is design size on components/ subassemblies of the Heavy duty End Face Milling Machine. For this specific DX5080, the overall sizes of the machine and subassemblies are as this:
1) Total height of the entire set of DX5080 Large H Beam End Face Milling Machine is 7.5m;
2) Total length of the entire set of DX5080 Large H Beam End Face Milling Machine is 11m;
3) Total widthof the entire set of DX5080 Large H Beam End Face Milling Machine is 2.5m;
4) Base bed height is 700mm (The standard height is 500mm);
5) All the units of this large Steel Structure End Milling Machine are made of high strength steel plates of 20~30mm thickness (The 30mm thickness plates take majority);
1) All the sub-assemblies of the DX5080 Large Welding Structure End Face Milling Machine, including the 10.5m long machine base bed and 6.7m height column, are all machined integrally and assembled together, instead of pieced from segments. Thus can guarantee best degree of rigidity and strength of total frame of this large Welding Structure End Face Milling Machine;
2) The assembly process of the Large H Beam End Face Milling Machine is guaranteed with torque control: All the fitting connections have stipulated torque, and implemented with stipulated assembling tools depending on torque value and type of assembly;
c) The mechanical units of Large H Beam End Face Milling Machine, especially its machine base bed, are distributed all around large numbers of stiffeners at both external and internal --- For such large H Beam End Face Milling Machine, firmness and intensity is the No.1 factor to be considered all the whiles.
