This knurl CAN be used on CNC lathes. The manufacturers webpage shows this, and instructions included with the tool outline how to set it up in the turret, programming tips, etc.

Can.
Are seldom.
It is still a "form" knurler. Has a tad of forgiveness as to PD.
Cut knurls are uber-picky about pitch-diameter, pressure knurls less-so.
But CNC
nails diameter. First time, next time, every time, ALL the time.
So the simpler cut knurl is just one more rather ordinary tool on the dance-card.
Even so, I think the Loctite having replaced knurling to tighten is the bigger factor for knurling overall. Whether this unit was even much involved or never.
The knurling trick was actually a monkey-patch with far less predictable endurance even when it seemed to work WELL than modern loctites
routinely deliver.
And no. I am not trying to get you to lower your asking price! Seems fair to me for brand-new and undamaged goods!
But you did say:"I thought this would be getting more interest.."
JMNSHO, it may be "a while" before a buyer comes along ...if it is indeed a smaller pool of potential users that it once was.
I could be wrong. Happens a lot.
Meanwhile .."patience.." etc.
