Understanding Basics of CNC Milling

CNC milling is a computer-controlled manufacturing method. It involves removing material from a solid “blank” material, such as a chunk of aluminum, and turning it into the desired product, component, or part.

The blank workpiece is held in a vice or a similar holding fixture, which is mounted on a work table. This table is able to rotate and pivot for two axes of movement. Then, a rotating spindle with cutting tools mounted on it will remove material from the workpiece, based on a digital CAD file. This process is automatic.

Because the CNC milling machine can move on multiple axes, CNC milling with a 3 or 5-axis machine can produce extremely complex geometries and part features with unparalleled precision. Milling services are also cost-effective and provide extremely high levels of accuracy, versatility, and repeatability.

The Materials Of CNC Milling

CNC milling parts can be used on almost any solid material that is strong enough to hold its shape while being milled. This can include some types of glass, plastic, and metal, especially for CNC milling aluminum or milling stainless steel.

Here are some of the most commonly-used CNC metals.
  • Aluminum
  • Brass/bronze
  • Copper
  • Titanium
  • Nickel
  • Zinc
  • Steel/steel alloys
Many types of plastic are also used in custom cnc milling, including:
  • Acrylic
  • ABS
  • Polypropylene
  • Polyvinyl chloride (PVC)
  • HDPE
  • Polycarbonate
  • PET

We work with a wide variety of materials, including CNC milling plastic and metal milling service. For more information, please contact us with details about your project and technical drawings.

CNC Milling Surface Finishes

There are a wide variety of different surface finishes available at the CNCNOW facility. Here are a few different available CNC milling surface finishes which may be appropriate for your parts.

As-machined – The part will not go through any further finishing or machining after being made, resulting in a rough, ~125 RA µin finish

Brushed – By using a gritty polishing tool that moves unidirectionally, a satin-like, brushed-metal surface can be created.

Smoothed – We can achieve a smooth surface of between 62.5 RA µin and 32 RA µin by using special machine tools, providing a sleeker finish.

Anodized (Type II) – Clear and colored anodized finishes are available. This process deposits a thin layer of anodic oxide material onto the part, which changes its appearance and helps with corrosion and wear resistance.

Anodized hardcoat (Type III) – Type III anodization uses a thicker layer of anodic oxide material that further enhances resistance to corrosion and wear & tear

Electropolish – Using a specialized electrochemical process, electropolishing smooths out metal parts, removes burrs, and reduces the overall roughness of the surface.

Bead blasted – Bead blasting uses a high-pressure stream of glass beads to remove all tool marks from a part. Depending on how fine the beads are, this can result in a satin or matte surface. Bead blasting is mostly used for aesthetic purposes.

Powder-coated – Powder coating uses polymer paint that is applied electrostatically and cured under heat. This results in a boost to strength, wear-resistance, and corrosion. Powder coating is also available in a multitude of colors

CNC Milling Tolerance

AT CNCNOW, we use the latest 3 and 5-axis CNC machines that offer high precision and accuracy, and ensure tight tolerances for all of our machined parts. Our standard milling tolerances are:
  • 300mm (12”) part size – Tolerances of ± 0.125mm (0.05”), angularity of ± 0.5°
  • 600mm (24”) part size – Tolerances of ± 0.250 mm (0.10”), angularity of ± 1.0°
  • 900mm (36”) part size – Tolerances of ± 0.400 mm (0.15625”), angularity of ± 1.0°
