轴套是变辊距矫直机中的关键零件 ,它不仅要求材质力学性能高 ,而且加工难度大 ,特别是要求锥面 85 %的接触率 ,往往难以保证。以前一直都依靠德马克公司进口件生产。由于国外供货 ,成本高 ,周期长 ,为降低成本 ,缩短生产周期 ,满足车间生产要求 ,经过调查研究 ,终于实现了国产化。 Sleeve is a key part in the straightening machine. It requires not only high mechanical properties, but also difficult processing, especially the contact rate of 85% of the conical surface is often difficult to guarantee. Demag has always been relying on imported parts production. Due to foreign suppliers, high cost, long cycle, in order to reduce costs and shorten the production cycle to meet the production requirements of the workshop, after investigation and study, finally achieved localization.
