CNC Milling Overview

CNC milling machines primarily use a spindle-head and a variety of axis configurations to cut the workpiece into the desired shape. Mostly used for harder metals, CNC milling machines are still highly suitable for other materials as well.

Much like other types of CNC machines, CNC mills also use CAM software’s G-Code to create the instructions for the machine to carry out. The more axes there are on the machine, the more complex the G-Code is.

The reason why CNC mills aren’t used as much for softer materials is cost-effectiveness. CNC mills are most suitable for industrial manufacturing where both the tool head and workpiece are being moved..

Types of CNC Mills include:

3-Axis — these mills move the workpiece on X, Y, and Z axis, making them suitable for a wide variety of work.

4-Axis — for more continuous machining, 4-axis CNC mills add the vertical axis to rotate the machine.

5-Axis — in addition to the three traditional axes, 5-Axis CNC mills also have additional rotary axes, which allows for work on 5 sides of the workpiece and makes these machines more expensive to use.

Industries that use CNC Milling

CNC milling machines make the industrial manufacturing basis of many industries. Some of the most prominent industries using CNC mills are automotive, consumer products, aerospace and defense, R&D, medical, energy, robotics, and industrial machinery.
