Constant speed (closed loop between VFD and rev counter) is not the same thing as CSS, which is constant SURFACE speed.

Sorry I missed your post before Brad's detailing what it was. I thought it might constant spindle speed rather than surface speed so I get what it is now.

Still if the input signals are there and the output signal has somewhere to go designing the electronics won't be an issue. I'm looking into building a cnc controller for a Kingsland 150t press brake having already gone one for a Kingsland Hydraulic guillotine. The same boards could be repurposed for a lathe without much hassle (new software rather than having to redesign the hardware).
