4 Axis Cnc Vertical Machining Center VMC550

4 axis machining implies that a workpiece is processed in the same way it would be with a 3 axis machine, but has an additional rotary movement around the X axis, which is named the A axis. This rotation allows the workpiece to be cut around the B axis. This method is beneficial when holes or cuts need to be made on the sides of a workpiece. The addition of a fourth axis (A axis) allows a workpiece to be automatically flipped over, so the machine can remove material from both sides.

CNC Milling Machine 3 Axis VMC1260

3-axis CNC machining evolved from rotary filing. With a 3-axis CNC machine, the workpiece is stationary while the cutting tool moves across the X-, Y-, and Z-axes. The X-axis (vertical axis) is left to right along the lathe table, the Y-axis (horizontal axis) is from front to back of the table, and the spindle that drops from the top marks the Z-axis (depth). A standard 3-axis CNC milling machine has a table that moves the part to provide one or two planes of movement and a tool that provides the other one or two planes of movement. 3-axis machines are ideal for simple tasks that don't require intricate detailing or depth. As such, it is one of the most preferred techniques for creating mechanical parts for automation.
