Großserie mit festen und justierbaren Werkzeugen

Ventilgehäuse EN-GJS-400-15 – Schieberbohrung und Druckwaagenbohrung

Ausgangsituation beim Kunden

Ventilgehäuse

  • Großserie
  • Werkzeugeinstellung gewünscht
  • Hohe Maschinenstundensätze
  • Hohe Kosten für nachfolgendes Dornhonen

Special features of this solution

  • Ideally matched separate tools guarantee optimum preconditions for a reduced honing process
  • The honing process can be eliminated with certain part requirements

Spool bore

MAPAL Boring

1. Boring
  • Optimum results in the pre-machining due to a coordinated piloting and boring process
  • Optimum chip flow and extended regrinding options through multicut technology and perfect coolant supply
  • No ring formation in the cavities due to special bore geometry → no costs for removal of rings

Control edge machining

2. Control edge machining
  • Solid carbide profile tool
  • Highest accuracy and surface finish of control edges
  • Defined control edges without macroscopic flaws

Fine boring

3. Fine boring
  • Fine boring tool with EasyAdjust system and guide pads
  • Reliable precision machining with easy handling
  • Best cylindrical forms due to optimum guidance

Compensator bore

Boring

1. Boring
  • Solid carbide boring tool with six margin lands and special lead geometry
  • Straight bore, ideal chip flow und guide across the entire bore length
  • Reduced non-productive times due to two machining operations in one tool

Fine boring

2. Contour machining
  • Double edge boring tool with form cutting edges
  • Reliable machining of the contour
  • Easy handling with low cutting material costs

Fine boring

3. Fine boring
  • Fine boring tool with EasyAdjust system and guide pads
  • Reliable precision machining with easy handling without subsequent honing
  • Best cylindrical forms due to optimum guidance

PRODUCTION COSTS PER SPOOL BORE

Advantages

  • Expensive honing process shortened in spool bore
  • Low tool costs per bore
  • Shorter non-productive times due to clever engineering in cooperation with the customer
  • Significant cost savings, as honing process no longer required in the compensator bore
