The 4-axis machine consists of four working axes: X axis, Y axis, B axis and A axis. Usually, the x axis controls the left and right movement of the workbench, the Y axis controls the forward and backward movement of the workbench, the B axis controls the rotating action of the workbench, and the A axis controls the up and down movement of the workbench. However, depending on the brush style, the Y and B axes may be designed to control the rotating or swinging action of the table.
