Precision CNC Machining: Tolerances and Standards
Our manufacturing processes adhere to strict international engineering standards. While our standard standard tolerances for metals follow ISO 2768-f and plastics follow ISO 2768-m, We can achieve much tighter project-specific tolerances as indicated on your technical drawings.
| Standards | CNC Milling | CNC Turning | Remark |
| Maximum Part Size | 4000×1500×600 mm | 200×500 mm | With precision CNC machining services, SHD is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements on your drawing. |
