- new electric cabinet
- new wiring inside the machine and between machine and cabinet
- cambering device is changed from a gear box to a ball bearing spindle with electric motor
- new motors for the head stock, z and x axis

REFURBISHMENT
The remanufacturing job was done by company KPM USA, a daughter company from HERKULES/WALDRICH SIEGEN. The price of the complete remanufacturing was US$ 700,000.
After remanufacturing the machine worked for only for 500 hours, then the paper mill (four paper machines) was closed. The machine is absolutely in as new condition and has still the accuracy of a new machine. In z and x axis, the guide ways are hydrostatic, also the grinding spindle bearing.
The new price from WALDRICH SIEGEN of a large machine like this is 4,7 Mio Euro.
It is a unique possibility to get a top machine for less than 25 % of the new price.
