Situação inicial no cliente

Claw vacuum pump

  • Altos custos de ferramentas devido a soluções de ferramenta sem flexibilidade no processo em série 
  • Redução enorme de custos por meio de proporção de usinagem na produção das garras 

Special features of this solution

  • Low cutting material costs thanks to a solution with indexable inserts
  • Combination tools and MAPAL fine boring technology for optimal process design and adherence to critical form and position tolerances without additional tools
  • Large standard range of solid-carbide end milling cutters offers high degree of economic efficiency for trochoidal milling of challenging workpiece materials
  • Soft-cutting tangential indexable insert requires less spindle power
