CNC Milling Services

CNC milling mills produce parts of nearly any shape from soft metals like aluminium, harder metals like steel,and plastics such as acetal.BOEN offers cost-effective milling solutions whatever you need a single part,batch of prototypes or full production.

We have the equipment ,the resources and the engineering talent to produce complex and tight-tolerance parts with our precision 3- / 4- / 5-axis CNC milling centers,combined with our other advanced capabilities Sheet Metal Fabrication, 3D Printing and our skilled team,we are able to delivery full-service solutions for your custom machining milling and manufacturing needs since 2007.

What is CNC Milling?

Computer Numerical Control(CNC) is a manufacturing process in which programmed in computer software dictates the movement of factory tools and machinery.Advanced programming software which optimized machine setting,cutting time,surface finish,and fine turning tolerance is used to control a CNC turning milling machines according to the instruction of clients’ CAD drawing file. In today’s CNC machining,the production of parts via pre-programmed software is mostly automated.The dimensions for a given part are set into place with computer-aided design(CAD) software and then converted into an actual finished product with computer-aided manufacturing software.CNC Parts production lines are not only to manufacture turning part work-pieces and prototypes,but also to build molding tools,which are to be used for the process of Plastic Injection Molding or Vacuum Casting .


The Process can be used to control a range of complex machinery,from grinders and lathes to mills and routers. With CNC machining milling,3D cutting tasks can be accomplished in a single set of prompts.

Benefits of CNC Milling Services

Let’s learn what the advantages of the CNC Milling are, the following is the benefits of CNC Milling Services:


 Can produce parts of almost any shape

Cost-effective for prototyping and short runs

​​​​​​​ Quick remove large amount of spare materials

​​​​​​​ Wide range of materials,variety of plastics and metals

​​​​​​​ Smooth finishes can be achieved

​​​​​​​ High dimensional tolerances are possible

Design Consideration for CNC Mills parts

Here are some consideration when make design for CNC milled parts.


 Avoid flimsy shapes

Avoid deep pockets and ensure corners are rounded

Milling creates a visible out pattern on the surface of the material

​​​​​​​ Use shapes that will hold well during machining ,like straight edges

CNC milling Tools

CNC Milling Tolerances

With a wide range of CNC machines at Boen , we’re capable to offer stand tolerance CNC milled machined parts with good offer and supper precision machined parts of for the high-end parts. We guarantee all parts to be made according to your every specification. If you have no special strict tolerance request just informed us it’s ISO2768MK.
The below table summarizes the standard tolerance of the parts produced by certified BOEN manufacturing partners.
Standard Tolerance for CNC Milling
Part Size / Dimension  Tolerance Angularity
<12”(300mm) +/- 0.125mm +/- 0.5
<24”(600mm) +/- 0.250mm +/- 1.0
<36”(900mm) +/- 0.400mm +/- 1.0
Large parts are reviewed on request,submit an order to begin.
And the following table is the size limitations for CNC milling service in BOEN
Size Limitations for CNC Milling
Maximal part size 2000*1200*800mm
Minimal part size 0.5mm
Minimal diameter 0.3mm

CNC Milling Materials & Finishings

If you’re considering to manufacture your parts with CNC milling, it’s very important to know what kinds of materials and surface finishing you will choose for your CNC milled parts no matter plastics or metals.

We’ve worked with wide range of materials and can apply all types of treatment to your CNC milling prototypes. Thanks to dedicated engineers and surface finishing colleagues. Are you sourcing custom CNC milling parts with high appearance or good protection? Boen is here for you.

CNC Materials

Plastics : ABS, PP, PMMA(Acrylic), PC, POM(Delrin), PBT, Nylon(PA), PU, RESIN,PEEK,PE,PTFE(Teflon),G-10(FR-4), PVC,EVA,EPS, Ultum 1000( AMBER PEI )

Metals: Stainless Steel, Steel, Aluminium, Brass, Copper, Iron,Magnesium,Tool steel,Alloy Steel

What’s More: We’re capable to create custom material like PA GF30 PPS30. It’s no problem for us to do further discovery for more materials. To get started with our team.
CNC Finishes

As Machined: The common and most economical way for inner function parts. Fine and even tool path is also good for aspect parts.

Powder Coating: It’s where powder paint to be sprayed onto a part and to be baked on the oven. This will create strong ,corrosion-resistant layer that is much durable than standard painting process. A wide variety of colors are available to create the desired aesthetic.

Anodized: Parts can be anodized in different colors-clear,black,red,blue are most common; Hard anodize is thicker and creates a wear-resistant layer.

Bead blasted: With this finish the part would be matte appearance.Range of 120-320 beads is flexible to create different roughness to the surface.

Chrome Plating: It’s of electroplating a thin layer of chromium onto a metal object.The chromed layer can be decorative with corrosion resistance,ease cleaning procedures,and increase surface hardness.

Painting: The parts no matter plastic or metal ,to be sprayed painting onto the surface to achieve the desired aesthetic. A wide variety of colors are available.
