What is CNC Milling
CNC milling is to cut solid plastic or metal material into final precision parts using different axis milling processes. Unlike CNC lathes, CNC mills remove material from the workpiece by rotating and moving a cutting tool, such as a milling cutter, and position the workpiece properly, to create a finished or semi-finished shape.
The multi-axis milling machines realize a versatile, accurate, and repeatable CNC milling process for the production of different features and complex geometries. Take channels, holes, curves, and corners for some examples. Milling can be also used as a perfect way of making tooling for die casting and injection molding.
Our advanced facilities conclude imported 3-axis, 4-axis, and 5-axis CNC mills that are equipped with different tool sets to maximize production efficiency and speed. Send us your inquiry or 3D files online to get an online quote for free now.
CNC Milling Process
The basic production steps
The first step is using CAD software to design a part with desired geometry. Then you can submit your 3D CAD files online and get an instant quote for free. Upon all details having been checked and determined, your digital design will be put into production immediately.
Why Choose CNC Milling
CNC milling is an ideal choice for manufacturing angled shapes, planes, grooves and channels, holes, curves, chamfers, and many other features.
Milling is not only used to manufacture finished parts, but also used to build molds for plastic injection molding and pressure die casting.
CNC milling machines can remove a large number of materials quickly and accurately, and produce good surface finishes at the same time.
CNC milling can machine different parts with a variety of materials. This process can be carried out on any rigid material.
Milling is the most versatile of all available CNC machining processes.
Because no other specialty tools need to be manufactured and no requirements for minimum order quantity, so the process is highly cost-effective and almost no waste compared with additive manufacturing.
Minimal setup time makes it possible that CAD files can be converted to finished products in a few hours.
Different Types of CNC Mill
Generally, the type of CNC mills is defined according to their number of axes. With more axes, the ability to manufacture complex parts and create cutting angles is enhanced and strengthened.
3-axis CNC milling machines
the cutting tools can travel along the X, Y, and Z axes.
-
4-axis CNC milling machines
similar to a lathe, add an extra degree of movement by rotating on a vertical axis, allowing to make more complex parts.
-
5-axis CNC milling machines
the most complete mill, incorporate two extra degrees of movement by adding rotation to the worktable and spindle. Components are processed in a single setup without being moved through several workstations.
CNC Milling Materials Options
We provide more than 50 types of plastics and metal blocks with different specifications for CNC milling.

CNC Milling Surface Finishes
Different surface finishing is available for milling parts, such as painting, anodizing and chroming. This will combine function and appearance process greatly.
Without any surface treatment processing methods, the parts will leave visible tool marks and burrs, which can be completed quickly and cost-saving.
A surface treatment process to obtain a certain degree of cleanliness and different roughness on the surface of the workpiece. The surface after sandblasting is dull and matte.
Many colors（such as black, red, blue, etc.）are available. Divided into Type II (normal) and Type III (hard), Type III is usually thicker than Type II and more corrosion resistant.
The powdered paint is sprayed onto the surface of the workpiece by electrostatic spraying to form a powdery coating, and then the powder layer is cured by heating and baking to level it into a uniform film layer. It is usually used for appearance parts, and a variety of colors is available.
Request an instant RFQ and we will offer you the appropriate surface finish for your project if you still do not see the finish you are looking for.

CNC Milling FAQs
Different from CNC lathes or turning centers where a stationary cutting tool removes material by making contact with the spinning workpiece, CNC mills cut away block or bar stock by a rapidly rotating cutting tool moving against the workpiece. The tool path is controlled by computer instructions, enabling improved reliability and repeatability regardless of potential human error.

- Form Milling
- Face Milling
- Angular Milling
- Profile Milling

At Runsom, our automatic tool changers can encompass drilling, boring, counter boring, counter sinking, profiling, cutting, reaming, threading, tapping, and other operations complete in the same setup. We can produce almost any shape of CNC components with various tooling and ingenuity in professional milling centers. Parts' dimensions and features decide the selection of multiple axis machines. And a single setup will ensure the accuracy and quality of components with complex geometry. Multi-axis milling needs complex, skillful, and meticulous programming, so a precision 3D CAD file will reduce our quoting and programming time. Elements such as tolerance, surface finishes, part size, tooling, and material properties will affect quotation directly. Now upload your CAD file, and get a quote from Runsom.
We provide professional design considerations as follows:
- Avoid Sharp Internal Corners.
- Avoid Narrow, Deep Slots.
- Avoid flimsy shapes.
- Corner radio of 10% or more of wall height is ideal.
- Avoid flimsy shapes.
- Practical shape as straight edges.
- Weak shapes are difficult to be milled, such as long thin shapes and thin walls.
- Visible cutting surface pattern for cutter rotation and movement.
