Jig milling machines A significant part of modern CNC milling machines has the ability to handle blanks in three independent coordinate axes. 3-axes units milling cutter produces a longitudinal and transverse motion in the horizontal plane, parallel to the desktop and attached to it the billet. This corresponds to the X and y axis To 3-axis machine these movements are made by moving the table with the workpiece. Vertical movement in the Z-axis to 3-axis machines can be carried out by moving the table or spindle unit. In the case of the movement of the table with the workpiece it is made with hydraulic console. This method has significant drawbacks because it requires the movement of massive parts.
