CNC Milling Services

Our precision CNC machining services provide rapid milling and high accuracy to manufacture custom metal and parts. Our CNC Machines are able to quickly cut 2D and 3D parts with high precision – no matter the part or prototype. 

Our machine shop provides access to 3-axis, 4-axis, 5-axis milling with 90 degree capabilities. With our various machines, we’re able to create and produce CNC milled parts that can range from simple parts to complex prototypes. At Thieman, we provide Same-Day pricing to help your project get started faster.

CNC Milled Parts & Applications

Plasma cutting creates a cost-effective way to cut thicker metals, and develop them into final components for usable parts and structures.

The chassis we fabricate are typically used to house electromechanical controls, from small handheld devices to large industrial testing equipment. All chassis are built to critical dimensions to ensure hole pattern alignment between different parts.

TMT builds custom brackets and miscellaneous laser cutting components. Our capabilities allow for fasteners and additional conveniences to be built-in to almost any manufactured part. 

Our CNC Milling Process

Step 1: The Process of CNC Milling begins with a CAD (computer-aided design) of the part you are looking to get made.

Step 2: The CAD file is then converted into a CNC supported file that navigates the movement of the CNC mill showing it where to move, how fast it should spin, and where the metal should move.

Step 3: From there, the milling tool starts to rotate on a spindle and begins the cutting of the final shape. Speeds can reach up to thousands of RPMs.

Step 4: Once the shape is cut, the part is then finished with the appropriate finish and then ready for the post-production process.

Metal Finishes for CNC Milled Parts

An as-milled option is viable for quick turnaround and parts that do not require visual appeal. Leaving the parts with an unfinished surface with visible marks from machine and potentially rough or sharp edges. 

Also called “Bead Blasting,” this finish creates a smooth matte appearance on metals.

Parts and applications may have an anodized finish for a wide variety of custom colors, which may include clear, black, gold, or desired custom colors.

  • – Type II Anodized Finishing creates a finish that is resistant to corrosion.
  • – Type III Anodized Finishing creates a thicker finish that is more wear resistant than its lesser option.

Powder coating is a painting process where powdered paint is sprayed on a part or application prior to heating. The result is a strong layer that is more resistant to wear and corrosion.

This process also allows for a wide selection of colors for the further  customization of color.


Also known as Chem Film or Chemical Conversion Coating, this metal coating provides corrosion resistance and conductive properties. This coat may also be used as a base for painted or color finishes.


If a custom finish is required for an order, or the finish is not listed on our site, please include this information when requesting a quote. We can likely still complete the project.
