我公司引进开发的新产品SZ904技术含量高,制造难度大,其中的动力输出从动轴零件具有3个或3个以上台阶,截面尺寸变化较大。采用连续淬火时,零件硬化层分布及深度受功率和移动速度影响很大,因此该零件淬火过程中因工艺参数的变化,往往需要变速度、变功率,普通淬火机床工艺参数调 The introduction of new products developed by our company SZ904 high technical content, manufacturing difficulty, which power output driven shaft parts with three or more than three steps, larger section size changes. The use of continuous quenching, part hardening layer distribution and depth of the power and moving speed greatly affected, so the part quenching process due to changes in process parameters, often require variable speed, variable power, ordinary quenching machine tool process parameters
