"In principle, the Helitronic Diamond is a Helitronic Power or Helitronic Vision grinding machine with an additional generator for electrical discharge erosion and the requisite peripherals, such as a quenching system", explains Martin Hämmerle, product manager for the Helitronic machines.
He points out that for rotary eroding on the Helitronic Diamond, no additional Walter-specific eroding control is used. This is integrated into the FANUC CNC control. "In this way, when tool grinding or eroding, the user can benefit from having only one control and thus only one supplier."
In order to enable the communication to the generator and the use of existing algorithms for electrical discharge erosion, FANUC agreed to modify the control accordingly. Heinz Häckh, Head of Control Engineering: "Based on our experiences with rotary eroding, we put forth concrete specifications and expressed various wishes, which FANUC implemented as an option in the 31i -A5 CNC."
