客户的初始情况

Stator bore, Rotary vane vacuum pump

  • 由于需求量的显著增加引发了对产量进行优化的进一步要求,同时工艺可靠性也要继续提升。 
  • 在加工定子孔时,由于预铣削和精镗削使得加工工作量投入极大 

解决方案的特性

  • 得益于多切削刃的刀具解决方案,实现了更短的循环时间,并大幅了提高经济效率 
  • 通过 EA-系统,使批量加工流程中的操作变得更简单 
  • 由于CBN切削刃材料的长寿命使用特性,使得精镗刀具的刀具配置频率大幅降低 
  • 通过采用可转位刀片的解决方案,也大幅缩减了切削材料的成本 
  • 针对各种不同的铸造材料加工,可以轻松实现极高的重复利用率。

定子孔

  • Stator bore, roughing

    粗加工

    镗刀  

    • 切向镗刀配备可转位刀片和筒夹,通过实现均衡切削去除量,获得最佳的预加工效果 
    • 通过使用冲压切向可转位刀片,大幅降低切削刃材料成本 

  • Stator bore, finishing

    Finishing

    Fine boring tool 

    • Multi-stepped fine boring technology offers the highest degree of quality when machining interrupted cuts
    • Low cutting material costs for series production processes thanks to HX indexable inserts

Stator bore Machining time per bore

Advantages

  • MAPAL tool solution provides process optimisation by means of cycle time reductions
  • Significantly increased output and reliable machining of the pump housing
  • Setting part no longer required due to omission of spindle system
