Straight from the machine with consistent accuracy and visible tool marks that meet engineering standards.
As Machined refers to the natural surface condition directly produced by CNC machining, without any additional finishing processes such as polishing, sanding, bead blasting, anodizing, or coating. This finish preserves the clean, technical look of the machining process, with uniform tool marks and excellent dimensional accuracy.
Utilizes rotating cutting tools for high-precision machining of flat surfaces, curves, and complex parts, ideal for mold making, aerospace, and automotive industries.
Uses rotating workpieces and cutting tools for efficient machining of cylindrical components, widely applied in shafts, discs, and precision parts manufacturing.
Enables multi-angle precision cutting, reducing setups and machining complex surfaces, perfect for high-end aerospace, medical devices, and precision mold manufacturing.
Typical surface roughness ranges from Ra 1.6–3.2 μm, providing a reliable balance between appearance, performance, and cost. While not intended for cosmetic applications, the finish delivers the precision and consistency required for engineering, mechanical, and assembly components.
Surface uniformity may vary slightly depending on:| Finish Level | Roughness Grade | Description |
| Standard As Machined | Ra 3.2 μm | Standard machining finish |
| Fine Machined | Ra 1.6 μm | Fine machining finish |
| Ultra-fine Machined (optional) | Ra 0.8–0.4 μm | Ultra-fine machining or finishing pass |
