Small and medium series with fixed tools

Valve housing EN-GJS-400-15 – spool bore

Initial situation at the customer

Valve block

  • Individual orders, smaller and medium quantities
  • No option for tool setting
  • Short cycle times required
  • High machine hourly rates
  • Stable oscillating honing available
  • Tool concept adapted to several part versions

Special features of this solution

  • 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
