Use of Real Materials
CNC prototype machining can use a variety of production-grade plastic and metal materials, which allows engineers to use the same (or similar) materials as the final part to make prototypes to test the product’s performance, function, and manufacturing cost.
Highly Accurate and Repeatable
CNC prototype machining allows a higher level of accuracy and precision to be achieved, typically tight tolerance of ±0.05mm or better. These are repeatable tolerances that can be achieved time and time again during low-volume production runs.
Quality and Consistently Finished Surfaces
Prototype machining provides a consistently smooth surface finish with a typical machined surface roughness of Ra 1.6μm and super-finish machined surfaces up to Ra 0.2μm.
