| Design Feature | General Recommendation | Aizhuo Milling Capability | DFM Optimization Tips |
|---|---|---|---|
| Optimal Diameter | 0.3mm - 20mm | Equipped with 60 BST and Mingyang lathes, it specializes in mass delivery within this size range. | Designing the outer diameter of the part within the size of the standard bar can significantly reduce the rough turning time and material waste. |
| L/D Ratio | Ratio ≤ 3:1 or 4:1 | Thanks to the high-rigidity spindle, it can stably cut high-hardness materials such as SCM415H. | If the length-to-diameter ratio of the part exceeds 4:1 or the structure is extremely complex, it is recommended to choose our [Swiss-type Machining] service, which enables one-time clamping to prevent deflection. |
| Tolerance & Roundness | ±0.005mm | Equipped with the Marr MMQ 150 roundness measuring instrument, it controls concentricity at the micrometer level. | For key cylindrical surfaces involved in fluid sealing or bearing fits, please clearly specify the requirements for concentricity and runout. |
| Threading & Undercuts | Standard Metric/Imperial | Provide extremely smooth turned threads, as well as subsequent treatments such as gold plating and silver plating. | Try to use standard threads and design an undercut at the end to significantly improve the efficiency of mass cutting. |
