Description

Wotan B75/105MNC NC Boring Mill, 1980s
50 taper in spindle, diameter 4” Table size: 36” x 39” Capacity: 4,000 pound Allen Bradley controls, small memory, need to drip feed programs if you are doing surfacing work. X travel: 52” Y travel: 38” Z travel: 31” U travel: 360 degrees continuously Spindle travel: 20” This machine uses Heidenhain glass scales for position. Machine is accurate within a few thousands in X, Y, and Z axis. Ball screw backlash is not an issue with the machine relying on the DRO for position. 480 VAC 3 phase only Ball screw drives. Issues with the machine: The machine has a problem with the memory, once the machine is turned off, the part program memory is erased. Desktop computer to load and save programs (RS232). All machine memory works ok. Spindle is mechanical. Currently power feed on spindle is not working. The motor is working, the problem is in the control circuit for the feed. U axis only repeats within .015” over 36” of X axis travel. If you are running parts needing to be rotated with high precision, you need to use an indicator to “ZERO” the table each time. Machine comes with approximately 30 to 40 tool holders, and a custom made spindle support when milling with the spindle extended. I could also include a aluminum tomb stone block if the buyer wants it. It’s a great German engineered machine to last a long time.
