What is CNC Machining?

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 Pressure Die Casting.


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

Benefits of CNC Machining Services

CNC machining is a practical option for everything from prototype manufacturing to production runs. The following is the benefits of CNC Machining Services:

 Quick turnaround

High accurate and can be repeated in exactly the same manner over and over again

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

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

​​​​​​​ Small and micro parts

​​​​​​​ Low investment in tooling making and preparation

CNC Machining Tolerances

Standard Tolerance for CNC Machining

The below table summarizes the standard tolerance of the parts produced

 by certified BOEN manufacturing partners
Part Size / Dimension Tolerance Angularity

3 or 4 Axis CNC Machined Parts

More >>

BOEN provides 3 or 4 axis CNC machining services with vast variety of CNC milling,CNC machining,CNC turning ,grinding.

As 3 or 4 axis machining is suitable for parts with shallow features,such as pockets and grooves.The 3 or 4 axis machining is one of the most widely used techniques to make mechanical parts.


Benefits of 3 or 4 axis

 Efficient,accurate machining of simple parts and enclosures

Wide variety of work holding available

5-Axis CNC Machined Parts

More >>

Our 5-axis machining provides a large variety of possibilities no matter for the part sizes and shapes we can effectively process the part in short time. 5-axis machining offers the highest precision and quality available.

BOEN provides precision 5-axis CNC machining services are ideal for prototypes and small batch production,because our turnaround times are very fast to repeat it again and again.

CNC Machining Materials & Finishings

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

We’ve worked with wide range of materials and can apply all types of treatment to your CNC prototypes. Thanks to dedicated engineers and surface finishing colleagues. Are you sourcing custom CNC 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.
Surface 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.
