CNC Milling

Home/CNC Milling

When the term ‘5 Axis’ is used in relation to CNC milling it refers to the ability of a CNC machine to move a part or tool in 5 different axes. 3 axis machining centres move a part in two directions (X and Y), and the tool moves up and down (Z). In 5 axis CNC Milling the cutting tool/machine moves across the X, Y and Z linear axes in the conventional way but also rotates in the A and B axes to approach the workpiece from any direction. This means that five sides of a part are processed in a single set up allowing complex parts to be manufactured in the most efficient and cost effective manner.
