Yes, thats a 30Year old machine. they used bergerlahr 5fase steppers, with a strange driver as well.
But as long as the machine run without problems, i don't change the control and drive parts of it.
The precision is rather limited, but I don't need often H7 or smaller. In the mill its another thing,
if I want a bore for a bearing, it must be within 1 or 2/100mm. I can't easy grind it to the next tolerance end.
