过去我们加工30CrMnSiA 合金钢φ120×250盲孔零件,是采用一般钻、车机械加工方法。由于材料韧性好、强度高、切削性能较差,钻、车一个孔需5～6个工时,并把大量贵重金属钻、车成铁屑而浪费掉。在兄弟单位“通孔套料”的先进经验基础上,结合生产实践,通过反复试验,改革成功了“盲孔套料”工艺,生产效率提高2～3倍,降低了劳动强度,节约了材料。
In the past we processed 30CrMnSiA alloy steel φ120 × 250 blind hole parts, is the use of general drilling, car machining methods. Due to good material toughness, high strength, poor cutting performance, drilling, car a hole to be 5 to 6 working hours, and a large number of precious metal drilling, car into scrap iron and waste. Based on the advanced experience of brother unit “through-hole nesting material” and combined with production practice, the “blind hole nesting” process has been successfully reformulated through trial and error to increase the production efficiency by 2 to 3 times, reducing labor intensity and saving materials .
