Hi Jens, sorry mate I got rid of it on Ebay. It was a nightmare when it was on the manual machine before I converted it. It was driven by pneumatics, 3 pistons and two large boxes of electronics and also had to have the spindle stop in the exact rotational position within 1 degree for the BT35 holders driving dogs to engage in the spindle and tool changer to work. Add to that when the spindle got warm the pneumatics were not powerful enough at 100psi to release the spindle taper, had to tap it with a copper hammer to release it. If you have BT35 holders you defiantly need to stop the spindle in the exact position, once you have done this the best way is to utilise a 4 axis steeper driven rotary unit with 6 tool holder slots, so cutting out the need for extra electronics. (PS the draw bar was also activated with pneumatic pressure) I now use a pneumatic push button and a dwell in the program to change tools, somewhat defeats the idea of CNC, but I'm a retired engineering hobbyist so time is not a factor.
