薄壁机加件变形控制是机械加工中比较棘手的问题，对于包含渗碳淬火工艺的合金薄壁件更是如此。针对12CrNi3A工作圈渗碳前的工艺控制，采取了细化工艺路线、优化装夹方法、增加预先热处理工艺等措施，通过实践验证，零件变形得到了很好的控制。

Deformation Control of thin-wall machining is a hard nut to crack in mechanical processing, for alloy thin-wall parts which contains carburizing quenching process all the more so. Aiming at process control of 12 crni3a work world be-fore carburizing, the paper was adopted methods of refining process, optimization of the clamping and increasing the heat treatment process. Through practice verification, parts deformation is well controlled.
