How do vertical vertical milling machines calibrate the spindle and workbench?
Note that the dial indicator head of the rotation diameter is best between 200-300mm.
But in the left and right direction generally want to stay a little (Jisi) angle (generally used in the larger case of the cutter), if it is an end mill, the best tie, without leaving the angle.
The first floor of the method is too earth, and there is no precision at all. With a hundred points fixed on the spindle, the table hit the table, with the slow rotation of the spindle, and adjust the nose, the spindle rotation for a week,
