How CNC Machining Works

CNC machining is a precise, subtractive process that begins with programming a combination of CNC tools to build a part directly from a CAD file. The machines etch out the design from a solid block of metal or other material to reveal the part shape. For larger or more complex parts,we’ll create the part in sections, then bond the sections back together to form a highly accurate part with a higher quality surface that’s ready for plating, painting or polishing.

Vertical CNC Machine

Here’s how our CNC machining solutions can help you:

  • Accelerate precision and timelines for tooling, progressive dies, and assembly fixtures in higher quantities.
  • Produce more complex parts with a variety of materials: aluminum, stainless steel, titanium, Invar, Kovar, brass, plastics, etc.
  • Take designs to production faster, including prototypes with complex geometries via CNC prototyping.
  • Create metal and non-metal surfaces with better acceptance of coatings and a variety of paint finishes.

Our CNC Machining Capabilities

Our CNC machining solutions offer more speed and material versatility to take your design from prototyping to production. Our team will work with you to ensure support on low, medium and large-volume production with quick turnaround times for prototypes, short runs and pre-production trials. Our materials and systems improve joining characteristics, increase uniformity of hardness/grain structure, and improve surface quality for more available finishing options.

CNC Milling

CNC milling machine work. Coolant and lubrication in metalwork industry
We combine 3, 4, or 5-axis milling and other processes to cost-effectively produce manufacturing jigs, fixtures and functioning prototypes in just days, for both higher quantities and production components in lower volumes.

CNC Turning

Metal machine tools industry. CNC turning machine high-speed cut
We use 2-to-8 Axis and Swiss Turning to create complex features such as slots, grooves, flats, and axial/radial holes. Our turning solutions deliver precision for small, complex parts, as well as for larger diameter turnings.

CNC Prototyping
