CNC Machining standards
We follow ISO 2768 standards for CNC Machining.

Limits for nominal size | Plastics (ISO 2768- m) | Metals (ISO 2768- f) |
---|---|---|
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
Over 6mm to 30mm | ±0.2mm | ±0.1mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 120mm to 400mm | ±0.5mm | ±0.2mm |
Over 400mm to 1000mm | ±0.8mm | ±0.3mm |
Over 1000mm to 2000mm | ±1.2mm | ±0.5mm |
Over 2000mm to 4000mm | ±2mm |
All parts are deburred. Tightest achievable tolerance is +/-0.01mm and is dependent on part geometry.
