Pompa per vuoto ad artigli

Corpo pompa in EN-GJL-250 | 
Artigli in 1.4021 (X20Cr13) 

Situazione di partenza del cliente

Claw vacuum pump

  • Elevati costi utensile dovuti a soluzioni di utensili poco flessibili nel processo di serie 
  • Forte pressione dei costi a causa della notevole percentuale di asportazione truciolo nella produzione degli artigli 

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
