We all know that the difference between a vertical lathe and an ordinary lathe is that its main shaft is vertical, and a vertical lathe is equivalent to an ordinary lathe upright. So what is Double column type milling machine?

Double column type milling machine is a kind of lathe, which belongs to vertical lathe, which is generally used to process the inner hole, outer circle and end face of larger workpieces. Double column type milling machine is composed of five parts: base, worktable, column, beam and tool holder. Among them, the beam part adopts a fixed beam design, so that the rigidity and stability of the entire machine tool is much better than that of a general moving beam lathe.
Double column type milling machine has the advantages of easy clamping of workpieces, oil-water separation structure, clean and environmentally friendly cooling water, long-lasting separated cooling water tank, easy to clean precision, high rigidity cartridge type spindle structure, easy maintenance and other advantages.
From the structural point of view, the lathe spindle of the Double column type milling machine adopts high-precision double-row cylindrical roller bearings, bidirectional thrust angular contact ball bearings, and double-row cylindrical roller bearings. The configuration structure has a large load-bearing capacity, can withstand large cutting forces and feed forces, has high radial stiffness and axial stiffness, and has high rotation accuracy.
It can be seen that the Double column type milling machine is more practical and beautiful than ordinary lathes, and it is an automatic CNC machining machine tool.
