TX32A铣销动力头上的弹簧涨套,壁薄、形状复杂,其技术要求为:HRC40～45,变形量≤0.10mm。生产中一般采用油中淬火和中温回火的热处理工艺,由于变形量很大(0.30～0.50mm)只好采用加大加工余量,然后进行磨削加工的办法达到技术要求。通过试验,我们采用了等温淬火工艺,
TX32A Milling sales of the head of the spring up sets, wall thin, complex shape, and its technical requirements: HRC40 ~ 45, deformation ≤ 0.10mm. Production generally used in oil quenching and tempering temperature heat treatment process, due to a large deformation (0.30 ~ 0.50mm) Had to increase the machining allowance, and then grinding methods to meet the technical requirements. Through the experiment, we used an isothermal quenching process,
