Heidenhain BE411 monitor have been either rebuilt or repaired by DNC for 10 years. Nowadays we build a LED replacement monitor which replaces the 12″ monochrome 226 917 01 CRT monitor. Running on the TNC155 control amongst other Heidenhain CNC systems. Our original solution to the rebuild was CRT solution, replacing the existing chassis, tube and wiring with our own electronics. Times are changing and CRT’s have slowly become obsolete from a rebuild point of view. Hence we moved onto LCD rebuilds into customers existing metalwork with the Heidenhain’s being a particular challenge meaning rebuild time was 24 hours rather than same day for most other brands. Now using our proprietary LED system, we are now offering off the shelve replacements to drop straight in place of your BE 411 monitor on your TNC155.
