Precision Machining Services

Precision machining can achieve extremely tight tolerances, often as small as ±0.0002 inches (0.005 mm) or better, depending on the machining method and equipment used. Machined parts as fast as 1 day.

What is Precision Machining?

Precision machining is a manufacturing process that uses advanced machinery and tools to create high-precision parts with tight tolerances, exact dimensions, and smooth finishes. The process involves the removal of material from a workpiece using cutting tools, abrasive wheels, or other techniques to achieve the desired shape and size.

Common methods of precision machining include CNC milling, turning, grinding, and EDM (Electrical Discharge Machining). These techniques allow for the production of complex geometries, intricate features, and fine details that require high accuracy.

Our Precision Machining Capabilities

Whether you need a plastic or metal prototype, an appearance or a functional prototype, our engineering team will evaluate the best production process based on the drawings to meet your needs.

CNC Machining

CNC milling and CNC turning are excellent options for rapid prototyping, especially when parts need to be evaluated in their final material and cut from fully dense stock. This process allows the machining of a wide range of metals and plastics, with many CNC parts being manufactured and shipped within a week.
Expedited CNC options are available for faster turnaround, and competitive, market-based prices make it possible to order multiple prototypes at once for quick product evaluation.
