Yes you can go directly to the lathe to finish grind. There is nothing you would need to do different than you would if it was done in a cylindrical grinder. The belts come in many widths and lengths, so you can purchase any type of tool post grinder to complete this task.
An example is attached on the link.

Hi pakalano
Can you please provide photograph of modified tool post grinder and specification of 3M Make Belts to grind HVOF coated tungsten carbide coatings.

We thankfully do have a lathe large enough with excellent accuracy and tolerances.. But can we use a belt grinder staright after coating. Dont we need to do any kind of tooling before polishing the coating with a belt grinder? Also, can you give me more details on the 3M made belt grade etc Response highly appreciated
Shantanu - see the other post I just did. There is nothing you need to do special to the coating. You will just need your best grinder operator to work with your lathe operator to come up with a recipe for finishing. Every part is different. We have managed to finish parts similar in size to yours within tight tolerance and still obtain a 4 Ra or better.
