What is CNC Milling?

CNC Milling is the process of cutting and drilling material (like plastic or metal). A milling machine, regardless of whether it’s operated manually or through CNC, uses a rotating cylindrical tool called a milling cutter. It is held in a spindle and can vary in form and size. The main difference between a milling machine and any other drilling machine is the ability to cut at different angles and move along different axes. Various complex parts can be processed quickly.

How is the CNC Milling Work?

CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic materials inside the CNC milling machine. The CNC milling machine will transfer the CAD model file into CNC readable program–G code, which is used to program the CNC machine rapidly mill our parts from raw material blocks. Our 3-, 4- and 5-axis CNC machines are equipped with different tool-sets to maximize production efficiency and speed.

What Materials can be CNC Milled?

We work with a wide range of plastic and metal alloy materials including magnesium, mild and stainless steel, aluminum, brass, and titanium as well as rigid engineering grade plastic resins. These materials are part of our standard inventory and can be sourced for immediate availability from reliable vendors who have been thoroughly vetted and approved by us. In addition, we can also provide specialty materials such as super hard alloys – just talk with our engineers to learn how we can meet your needs.

Most importantly, to ensure that your CNC machined parts meet all regulatory requirements we have an incoming materials inspection lab where we use sophisticated analytic testing instruments using Raman spectroscopy to confirm the exact chemical and physical properties of all raw materials. We leave nothing to chance for your peace of mind.





















Industrial Applications of CNC Milled Parts

The shapes that can be made by CNC Milling include various flat surfaces, tapers, contours, fillet and radius contours, and threaded surfaces. Although many turned parts use a single axis of rotation, there can also be multiple axes to provide greater flexibility (for example, camshafts).

Automotive industry:

engine, housing, screws, motor shafts, bearing sleeves, knobs, gaskets, shift levers, hydraulic valves, valve housings, sensor housings

Machinery industry:
