Séries pequenas e médias com ferramentas fixas

Corpo de válvula EN-GJS-400-15 – Furo do carretel

Situação inicial no cliente

Valve block

  • Pedidos individuais, pequenas e médias quantidades de peças
  • Nenhuma possibilidade de ajuste da ferramenta
  • Baixo tempo de espera necessário
  • Altas taxas de hora da máquina
  • Disponibilidade de um processo de brunimento expansão estável
  • Conceito de ferramenta adaptado a várias variantes de componentes

Características especiais da solução

  • No ring formation in the cavities due to special bore geometry → no costs for removal of rings
  • Optimum results in the pre-machining due to a coordinated piloting and boring process → Support of boring tools in the pilot bore = optimum straightness, position
  • High productivity with perfect pre-machining quality → High cutting values – machining time is reduced

Spool bore

Piloting

1. Piloting

  • Solid carbide-boring tool with six margin lands for perfect roundness and straightness
  • Optimum chip flow and extended regrinding options through multicut technology and suitable coolant supply

Boring

2. Boring
  • Solid carbide boring tool with three cutting edges and six margin lands and special lead geometry
  • Straight bore, ideal chip flow und guide across the entire bore length

Control edge machining

3. Control edge machining
  • Significant cycle time savings with special solid carbide circular milling cutter
  • Defined control edges without macroscopic flaws

Reaming

4. Reaming
  • Multi-bladed reamer for high cutting data
  • Perfect chip control due to left-hand twist and optimum coolant supply
