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

Shut-off valve, actuating tool

  • Automatic tool change for flexible tool deployment
  • Mounting tools can be offset in five steps to cover a wide range of diameters
  • Optimum coolant supply centrally via the mounting tool directly onto the cutting edge

  • shut-off valve, actuating tool

  • shut-off valves, actuating tool

Defined Surfaces (Grooved Surface)

Advantages

  • Large variety of parts handled by a single tool system
  • Machining of the flange surfaces and seat rings possible in a single clamping setup
  • No clamping errors and maximum productivity
  • Actuating technology enables burr-free contour transitions and short cycle times as well as the achievement of defined surfaces
  • In case of tool wear, tolerances and quality can be corrected flexibly
