Initial situation at the customer

Claw vacuum pump

  • High tool costs due to inflexible tool solutions in series production
  • Significant amount of machining in claw production creates massive cost pressure

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
