This is an indexer and not a lathe so the precision and holding torque are preferred over speed.If you look at 4th axis add-ons on eBay or amazon you’ll see reduction gear boxes or similar belt and gear configurations. This doesn’t need to rotate any faster that your cnc can cut or laser etch material.

Assuming you have 3inch diameter stock. Circumference of material is 9.42inches and assuming you can cut at 60ipm means you only need about 6.37rpm on the rotation speed and I’m sure this design will exceed that considerably.
