Capabilities

Everything from one part to a full production run

A focused set of milling and turning processes, run on the right machine for the geometry, the material, and the volume.

CNC Milling

3- and 4-axis vertical and horizontal machining of complex prismatic parts, housings, and fixtures in metals and engineering plastics.

CNC Turning

Turning centers with live tooling and a Y-axis for done-in-one round parts — drilled, milled, and tapped features without a second setup.

Multi-Axis & Done-in-One

Twin-pallet and traveling-column platforms keep long and heavy work cutting while the next part is loaded, reducing setups and lead time.

Prototyping

Fast first articles and design-for-manufacturing feedback so issues surface before you commit to a production run.

Production Runs

Repeatable low- and mid-volume production with in-process checks and lights-out capability on proven programs.

Materials

Aluminum, stainless, carbon and alloy steels, titanium, brass, copper, and high-performance plastics.

Equipment

The machine fleet

Mazak milling and turning platforms with the travels and capacity to handle small precision parts and large, long workpieces alike.
