Custom CNC turning services
CNC turning is a machining process where the workpiece rotates on a spindle while a fixed cutting tool removes material. It works well with metals and plastics and is ideal for producing axisymmetric parts. This method offers high precision, flexibility, and efficiency. It is also faster and more cost-effective than milling. At Yonglihao Machinery, we provide machining services with tolerances as low as ±0.1 mm, ensuring cost-effectiveness for both small and large batches.
Maximum part sizes for CNC turning
Our CNC turning services offer design flexibility for a wide range of part sizes. We handle everything from tiny precision components to large, complex structures. For example, when machining large shaft parts, we ensure stability to prevent vibration from affecting precision. Below are the key size limitations:
| Part size limitations | Metric units | Imperial units |
|---|---|---|
| Maximum part diameter | 431 mm | 17 in |
| Maximum part length | 990 mm | 39 in |
| Maximum swing over the carriage | 350 mm | 13.7 in |

CNC Turning Machining Tolerances
Using advanced CNC technology, we achieve strict tolerance control. This ensures each part meets design specifications. Our tolerances are based on the ISO 2768 standard but are optimized through our experience to suit real-world production needs. For example, finer tolerances in metal parts reduce assembly errors and improve system reliability. Below are the tolerance limits:
| 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 |
