Shut-off valve housing

Shut-off valve housing EN-GJL-250

Initial situation at the customer

sthut-off valve, actuating

  • Large variety of components (DN 65 – DN 300)
  • Flexible machining necessary on the machining centre
  • Challenging machining of parts to achieve defined surfaces

Special features of this solution

  • High feed rates possible; defined roughness depth Ra 12.5 necessitates minimum required feed rates of fz = 0.8 mm
  • Large radial stroke and modular tool connection enable a small number of tools to be used for all parts
  • Automatic tool change
  • Tool configuration does not affect machining times thanks to replacement tools
  • The flexible process allows preconfiguration to be done on a setting fixture
  • Indexable insert technology for low cutting material costs

Tool highlights
