CNC machining process, clamping and alignment of the basics of how

CNC machining process, clamping and alignment of the basic method is as follows:

① the workpiece clamping on four - jaw chuck, in order to increase the degree of freedom in the horizontal alignment of the workpiece when the direction of the outer and prevent damage to the pad in the chuck jaws at a copper strip.
② put a flat bed surface, alignment with the eccentric reference center line marking tape.
③ with crosshairs correction method, the disc will be crossed from left to right along the parallel movement on both sides of the line of eccentricity, and reverse a half weeks, repeatedly correcting the position of the workpiece and the stylus height, the eccentric and the vertical line at both locations and stylus highly consistent so far.
④ in opposite directions successively tighten each chuck jaws, and ensure alignment of the workpiece has the same position. If high precision CNC lathes eccentricity requirement can be seen as eccentric workpiece runout distance, direct dial wobble difference correction.
