What are the Advantages of CNC Milling?
CNC milling is a machining process that uses computerized controls and cutting tools to selectively remove material from a workpiece and produce a custom-designed part. A CNC milling machine features a table that automatically moves (or rotates) the workpiece on different planes so the cutting tool can work on it.
Unlike manual lathes, a CNC milling machine operates by converting a 3D CAD model into a set of computer instructions, which is then used to dictate the tooling’s actions and movements automatically.
Precision
One of the biggest advantages of using CNC milling machines is that they can create parts exactly to specification. Because CNC mills rely on computer instructions to fabricate parts, they eliminate the possibility of human error common in manually operated machines. This means you can accurately create complex parts while achieving tolerances as tight as 0.004mm.
Fast and Efficient
Conventional milling machines often require an operator to manually change cutting tools depending on the cutting operation to be performed. Not only is this time-consuming, but it is also inefficient as end results are based on the operator’s judgment. CNC mills feature rotating carousels that can hold up to 30 different tools. These tools are automatically exchanged on the spindle during machining operations, allowing cutting operations to be performed quickly and efficiently.
Wide Range of Material Options
CNC mills boast compatibility with a wide range of materials, including plastics, metals, and composites. So long as you’ve got blocks of the material, CNC mills will have no problem machining it.
Affordability
We can talk about precision, speed, and a ton of other advantages all day, but nothing beats affordability, especially for businesses looking to rely on third-party manufacturers. CNC milling is among the most affordable modern-day manufacturing processes.
