The machine was retrofitted and upgraded during the last several years:
? In 2000
Complete new electric and CNC control by Heidenhain TNC 430 incl. axis motors, linear scales, cabling, electrical cabinet etc.
? In 2004 
The beds were ground and polished, the aerostatic ways of the column on the bed was upgraded with a double pocket system which improves the motion accuracy. 
The y axis ways were reconditioned and all air nozzles were replaced.
? In 2008 
The Spindle head was modernized and redesigned. 
The hydrostatic spindle bearing was replaced by a roller bearing. This was the basic to upgrade the spindle speed form 1100 rpm to 1800 rpm. 
The main drive was replace by an asynchronous motor make KESSLER. All bearings in the gearbox were replaced. 
The spindle was redesign for to tapers SK 50 DIN 69871 and DIN 69872.
? In 2010 
The counterbalance system is hydraulic design. The pressure tank of the system was replaced.
　
The machine is currently in plant, under power in Germany. It will be removed from service in early February 2014
