As our advantage, we have full experience in project operation for large heavy parts and steel structures, which can be cut by CNC flame cut or laser cut, later it will be assembled and welded by TIG/MAG machine. Of cause the large heavy structures also need to be heat treated in order to release the inside stress before machining, and then it may be machined by gantry planing machine, large CNC milling machines, heavy lathes and large CNC grinding machine etc.
