CNC Machining Capabilities

Milling and turning under one quoting flow — prismatic parts, turned parts, and production runs with process controls, all with machinability feedback on upload.

Production Machining

We iterated three revisions of a housing in a single week. Machined parts kept pace with our CAD, not the other way around.

Prototype vs. Production Machining

The same machining technologies can support fast prototypes or scheduled production with inspection documentation. The comparison below clarifies the differences.

Advantages of CNC Machining

When accuracy, material selection, and finish all matter, machining is a strong option. Key advantages include:

CNC Machining Applications

Wherever metal or engineering-plastic parts do demanding work, CNC machining is commonly used. Typical applications include:

CNC Machining FAQs

Achievable tolerances depend on geometry, material, feature access, and inspection method. Identify critical dimensions on the drawing for a focused review.

Yes. A drawing helps communicate critical dimensions, datums, threads, surface finish, and inspection needs alongside the 3D model.

Machining is useful from one-off parts through planned production runs. Compare it with molding or additive manufacturing when volume and geometry change the economics.

Finishes can include anodizing, blasting, coating, passivation, plating, marking, and cosmetic preparation, depending on material and geometry.
