Davy Posted August 2, 2016 Report Share Posted August 2, 2016 Can anyone recognise this model of Heidenhain DRO and even better tell me how it works please, It is fitted to a 9x42 Textron built Bridgeport Milling machine.I am used to DRO's however nothing this old so any tips or information would be gratefully received. All I can say is it is not a VRZ 710C Link to comment Share on other sites More sharing options...

MrCetrizine Posted August 2, 2016 Report Share Posted August 2, 2016 it really looks like a VRZ710 Manual available here... http://content.heidenhain.de/doku/oma_vrz/html/en/index.html Link to comment Share on other sites More sharing options...
Davy Posted August 2, 2016 Author Report Share Posted August 2, 2016 Thanks all for the links, I have also dropped Heidenhain UK an email however it looks closer to a VRZ 613 2 Axis model. I was curious about the Memofix function and it looks like I can reference datums albeit in a limited fashion. It seems remarkably accurate for such old and basic technology.

Davy Posted August 3, 2016 Author Report Share Posted August 3, 2016 The model has been confirmed as a VRZ 731B by Heidenhain UK who also provided a manual. Apparently this was original fitment on some of the Bridgeport BR2J2 Milling machines. Link to comment Share on other sites More sharing options...
