Grinding attachments for a CNC Lathe

[Ineedto5s]

I have an issue with carrier rings for a large lap table. They require a 45 degree chamfer in order to push the slurry on the table. Problem is that it's approximately a 16.5 inch alumina ring, and we do not have an grinder with a big enough chuck. We do however have a CNC lathe (with turret) with a big enough chuck. Any options to make this work?

I've seen grinding attachments for manual lathes. Used to to use one to grind rubber rollers for printing transfer many moons ago.

I was hoping for something that could fit into a CNC lathe turret and be used. By no means does this need to hold tight tolerance. It is currently been done with a hand dermal.

Do you have live tooling on your turret? From what I see most of the mountings are DIY. There's probably a general reluctance to grind on a machine not meant for grinding - problems with grit getting under way covers and into coolant.

We make a lot of smaller components, so most of our equipment is aimed at the 0-3 inch diameter range. Yes one of them has live tooling.

I was wondering if we could do this on a jig grinder... set the work piece to over hang the table and rotate it under spindle...

You can mount a grinding wheel on a straight arbor shaft and chuck that into your CNC, if you have live tooling. Then dress the wheel so it runs true. Or get a tool post grinder.

I'll try this. Thank you!
