5-Axis Precision Machining

5-axis CNC machining uses computer numerical control (CNC) to move a machined part or a cutting tool along 5 axes at the same time. With the help of computer-aided manufacturing (CAM) software, we ensure synchronised and smooth operations to avoid tool path collisions.

To best understand the 5-axis CNC process, you must first understand how other basic axes machines work.

• A 1-axis machine has a tool that moves up and down on one axis. We refer to the up and down axis as the Z-axis. An excellent example of this movement is the up and down motion of a drill bit.

• 2-axis machines mill items on only the X (side to side) and Y (back and forth) axes.

• A 3-axis machine incorporates the vertical movement (Z-axis), the side to side (X-axis) and back and forth (Y-axis).

• A 2.5-axis machine generally has vertical functionality but will not move along the Z-axis when the X and Y axes are moving.

• 5-axis machines incorporate all the linear motion capabilities of the machines mentioned above but also have an additional two axes to allow rotary motion. This rotary motion is on the A and B axes. Movement across the axes allows the cutting tool to access the machined object from all directions. The overall benefit of this machine is efficiency and flexibility as everything can be done in one process with fewer set-ups.

Increased productivity

5-axis milling means very complicated parts can be machined quickly. This high-precision process can normally mill large parts by using one set-up. This increases productivity and reduces lead times for a faster turnaround.

Unrivalled accuracy & precision

Compared to machines with fewer axes, 5-axis milling has an unrivalled level of accuracy. With the help of CNC, this milling process delivers incredibly precise results; particularly helpful when an extra high-quality result is needed.

Versatility

Both the table and the cutting tool can be tilted and adjusted to have a constant chip load and to maintain the best cutting position.
