Flexible honing on the machining centre

Valve housing EN-GJS-400-15 – Compensator bore / honing

Initial situation at the customer

Valve block

  • Request for reduction of ancillary costs
  • Existing machining centre re-tooled to TOOLTRONIC
  • Honing for prototype manufacture, as well as small and medium-scale production runs
  • Requirement for saving the honing process on separate machine

Special features of this solution

  • A full NC axis incorporated in the machine control system
  • Shortening of production and lead times
  • Improved surface quality
  • Greater contour accuracy

  • Greater contour accuracy

Honing with TOOLTRONIC
Machining with MAPAL TOOLTRONIC achieves high surface quality and dimensional accuracy with tightest manufacturing tolerances as well as high flexibility in manufacturing. The wear of the honing bars is reliably compensated by a highly sensitive and precise actuating movement (EAT system).
