Axial piston pump – cylinder Block

气缸体 42CrMoS4 / CuZn35Mn2Si材料——活塞孔和肾形孔加工

客户的初始情况

Machining cylinder block

  • 中到大批量
  • 在加工特定表面和高品质要求时则成本较高
  • 专业人员普遍短缺造成较大的人力波动现象，但同时件数却在增加

解决方案的特性

  • 确保安全的同时可靠实现苛刻的工件质量要求。
  • 基于可靠的工艺流程加工出活塞孔的特定表面 
  • 通过Tritan-Drill und OptiMill-Uni-HPC Pocket工艺，取消了锪孔和镗孔工艺
  • LAT / EAT允许加工方案灵活地应用到其它变型变体结构组件上

活塞孔

  • Machining cylinder block

    阶梯钻孔

    阶梯钻头
    • 活塞孔的最佳预加工，无需额外的锪孔加工
    • 不再需要由于锋利的切削刃导致的孔底去毛刺流程

  • Machining cylinder block

    精镗

    精镗刀具
    • 在压入黄铜衬套之前，精镗刀具可确保完美的孔加工质量
    • MAPAL HX 切削 - 6 个切削刃，不仅实现了更低的切削刃材料成本，而且获得更高的经济性。

  • Machining cylinder block

    展开式刀具

    展开式刀具
    • LAT-车端面刀头，用于精密加工活塞孔上限定表面的细节 
    • 无需进一步的加工步骤，即可精确加工出黄铜衬套的导入轮廓

  • Machining cylinder block

    Actuating

    Actuating tool
    • EAT eccentric facing head for applications with high spindle speeds for maximal efficiency when machining brass bushes (premachining and fine machining)

Machining kidneys

  • Machining cylinder block

    Milling

    Milling cutter
    • OptiMill-Uni-HPC Pocket supports the required drilling process with inclined plunging when machining inlet and outlet openings (kidney-shaped holes)
    • The production process of pressure and suction kidneys of the corresponding control plate can be performed efficiently and without further tools

MACHINING TIME PER CYLINDER BLOCK [SEC.]

Advantages

  • Actuating technology allows efficient and high-automized “unmanned manufacturing” through automatic measuring and adjustment cycles during machining.
  • Reduces process and non-productive times and allows efficient multi-machine operation through high-tech tool solutions
  • Considerable savings in tool costs and machining time are achieved through actuating technology as the piston bore and brass bushes are premachined and fine machined without additional tools
  • Precisely coordinated processes between pre- and fine machining
