CNC prototyping belongs to the category of subtractive manufacturing, delivering outstanding accuracy and material flexibility while ensuring durability. This makes it highly suitable for producing prototypes that not only resemble the final design but also perform under real-world conditions.
By utilizing machines such as CNC turning centers and milling equipment, along with a range of specialized cutting tools, raw stock is shaped with remarkable precision based on digital CAD data.
Chiheng’s dimensional tolerances can reach as fine as ±0.005 mm or even better, which is critical when components must fit together seamlessly or undergo rigorous functional validation.
In contrast with additive approaches like 3D printing, CNC machining often involves higher costs and longer lead times when handling one-off designs with intricate, organic geometries. However, it stands out when creating working prototypes from metals and advanced plastics that share the same mechanical behavior as production-grade parts.
While 3D printing is generally preferred for rapid and inexpensive concept models during the early development stage, CNC machining becomes increasingly advantageous once projects move toward limited production runs. This enables a smooth progression from initial prototype to market-ready component.

About CHIHENG machining parts technology and news for your to know more about us
I work with 316L stainless steel regularly on CNC milling projects for the UK market, and it’s worth starting with what makes this grade special and why finishing it to a mirror polish is not straightforward.
Here’s one of the projects. A UK-based medical device manufacturer required a 316L stainless steel material for its critical surgical instrument components, along with a mirror-polished finish achieving a Ra value of ≤0.1 μm. This type of surface treatment is crucial for reducing bacterial adhesion, enhancing corrosion resistance, and meeting the ISO 13485 standard for the UK medical industry. The core challenge of this project was to overcome the high hardness and work-hardening characteristics of 316L stainless steel while preventing dimensional deviations caused by thermal deformation.
Melting temperature of metals is all about the the right cutting tools, coolant strategy, and machining parameters to your material, making sure we hit your tolerances the first time. At Chiheng, we’ve spent years perfecting how we work with metals that have very different melting points. From soft aluminum alloys to high-temperature titanium and steel, we know exactly how each material reacts to heat during CNC machining—and how to keep that heat under control. In this guide, we will walk you through the key knowledge of how melting affecting cnc machining processes.
