Technically the industry standard "90 volt nominal" dc motors used on the 6F and 8F power feeds as well as the Erskine controlled versions fitted to UK (Adcock Shipley) built machines are servo motors. It's the speed stabilised drivers that make them so. Albeit not in particularly sophisticated way but perfectly adequate for the feed drive job. Any of the open market control boards are up for that job. Affordable care just fine.

The one referenced to is just an all in one set up functionally similar to the 6F, 8F and aftermarket Servo (or copy) installations. Just belt drive rather than direct on the end of the feed screw. On anther part of the web site the firm also offer naked motor with separate controller systems which would have to be installed similarly to the UK Erskine based systems with the drive board in the electrical cabinet.

What I'd really like is something able to piggyback onto my DRO readout to stop the feed when the axis gets down to zero. Tappitty-tap-tap on the keypad is much easier than setting a stop switch just so. The guy who mentioned the standard stop bar and lever set up can go an stand in the corner.
