Since 1993 implementing technology for businesses where resources are non-existent or during a growth initiative.

APPROACH:
  • horizontal machining center with pallet shuttle
  • workholding and tool holders and cutting tools
  • custom macro B and parametric programming
  • automated workpiece and tool probing
  • broken tool detection

RESULT:
$20 (labor + material) main component to a $156 assembly cycle tested and shipped for $800 to $3,200.
