Drehschieber-Vakuumpumpen-Gehäuse

Pumpengehäuse aus EN-GJL-250

Ausgangssituation beim Kunden

Statorbohrung, Drehschieber-Vakuumpumpe

  • Deutlich steigender Bedarf und damit einhergehende Anforderung an optimierte Ausbringung und gleichzeitig erhöhte Prozesssicherheit
  • Hoher fertigungstechnischer Aufwand beim Bearbeiten der Statorbohrung durch Vorfräsen und Fertigspindeln

Special features of this solution

  • Short cycle times and the highest degree of economic efficiency thanks to multi-blade tool solutions
  • EA system enables easy handling in the series production process
  • Reduced frequency of tool configuration for the fine boring tool due to the long tool life of the CBN cutting material
  • Low cutting material costs thanks to a solution with indexable inserts
  • Repeated usage for different casting materials easy to implement

Stator bore

  • Stator bore, roughing

    Roughing

    Drilling tool

    • Tangential boring tool with indexable inserts and cartridges for optimal pre-machining thanks to consistent stock removal
