floating mandrel

To solve the problems in small diameter precision tube production,such as more drawn passes and unacceptable dimensional size or internal surface quality,floating mandrel drawn technology and composite external mould were adopted.

针对小径精密管冷拔道次多及空拔出成品时内、外径尺寸及内表面质量难以保证的问题,采用了游动芯棒生产工艺及复合外模生产精密管,结果表明,精密管的尺寸精度及内表面质量完全满足标准及用户要求。
