Vertical Lathe Machine working principle: the main feature of vertical Lathe Machine is that the spindle is upright, the worktable is in the horizontal plane, and the workpiece is clamped on the large worktable which is rotated by the spindle.Because the workpiece is installed on the horizontal worktable, it is more convenient to clamp the workpiece. The quality and cutting force of the workpiece are supported by the rotary guideway between the worktable and the base, which lightens the load of the spindle.Thus vertical lathe machine machining accuracy is easy to be ensured, and vertical lathe machine working accuracy can be guaranteed for a long time.Vertical lathe machine work movement: The work piece is mounted on the workbench, driven by the spindle for the main movement. Feed movement is achieved by the vertical knife and side knife.
