Explore our CNC machining services
Our CNC machining capabilities meet a wide variety of manufacturing needs. Explore our milling and turning services:
CNC Milling
CNC mills are effective for geometric designs and rapid production requirements. Our CNC capabilities include both 3-axis and 5-axis mills.
CNC Turning
CNC turning is a process in which an automated lathe shapes a rotating workpiece. Turning is useful for shaping rounded or cylindrical geometries.
CNC machining applications
Precise and quick to produce, CNC machined parts serve a spectrum of industrial applications:
Tooling
Manufacture parts with complicated cuts and angles using a variety of precision cutting, drilling, and lathing tools.
Niche manufacturing
Cut durable metal and plastic products that alternative processes can’t create. The CNC turning process is ideal for creating cylindrical parts.
Medium-to-high-volume production
Perform cost-effective production runs in the hundreds and thousands, scaling up and down as your business needs change.
Metal fabrication
Meet demand for high quality metal parts with exceptional tight tolerance requirements.

Surface Finishes for CNC Machining
| Anodizing | Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. | Aluminum | Clear, black, grey, red, blue, gold. | Smooth, matte finish. | Learn More>> | |
Bead Blasting | Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Matte | Learn More>> | |
| Powder Coating | Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Gloss or semi-gloss | Learn More>> | |
| Electroplating | Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common. | Aluminum, steel, stainless steel | n/a | Smooth, glossy finish | Learn More>> | |
| Polishing | Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection. | Aluminum, Brass, Stainless Steel, Steel | n/a | Glossy | Learn More>> | |
Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | satin | Learn More>> |

Understanding the Differences Between CNC Milling and CNC Turning
CNC milling is employed for greater precision, while CNC turning is chosen for higher efficiency. What is CNC Milling?CNC milling involves using a rotating cutting tool to remove material from a workpiece. The workpiece is typically held stationary on a table, while the cutting tool moves in multiple axes—usually along the X, Y, and Z […]
