Large series with solid and adjustable tools

Valve housing EN-GJS-400-15 – spool bore and compensator bore

Initial situation at the customer

Valve-block

  • Large-scale series
  • Tool setting desired
  • High machine hourly rates
  • High costs for subsequent single pass honing

解决方案的特性

  • 相互完美匹配的单把刀具保证了减少珩磨流程的最佳先决条件
  • 对于某些组件要求可以消除珩磨流程

滑块钻孔

MAPAL Boring

1.镗孔

  • 协调的导向孔和镗孔工艺可实现最佳的预加工结果
  • 得益于多倒角技术和完美的冷却剂导向装置实现优化的切屑流动和扩展的精磨削选项
  • 由于特殊的镗孔几何形状，在空腔中不会形成环圈 => 无去除环圈的费用

Control edge machining

2.控制刃口加工

  • 整体硬质合金型材模具
  • 最高精度和控制刃口的表面质量
  • 定义的控制刃口无破裂现象

Fine boring

3.精镗

  • 带有EasyAdjust-系统和导向板条的精镗刀
  • 工艺可靠的精加工，易于操作
  • 通过理想跟踪获得最佳圆柱形状

压力天平孔

Boring

1.镗孔

  • 具有六个导向倒角和特殊切口几何形状的整体硬质合金镗刀
  • 直孔，理想的切屑流和整个孔长度的导向
  • 通过在一个刀具中进行两次加工操作来减少非加工时间

Fine boring

2. 形状加工

  • 精密成型付き2枚刃ガンボーリング工具
  • 信頼性の高い形状加工
  • 容易な取り扱いで、工具材料費を低減

Fine boring

3. Fine boring
  • Fine boring tool with EasyAdjust system and guide pads
  • Reliable precision machining with easy handling without subsequent honing
  • Best cylindrical forms due to optimum guidance

PRODUCTION COSTS PER SPOOL BORE

Advantages

  • Expensive honing process shortened in spool bore
  • Low tool costs per bore
  • Shorter non-productive times due to clever engineering in cooperation with the customer
  • Significant cost savings, as honing process no longer required in the compensator bore
