I just got my new 3520C when i took off the face plate that was on for shipping i notice burs on the spindle from the set screws is this common. Is there a way around this so if i use the set screws i don't mark up the spindle I thought the spindle would be harden?they have set screws with nylon ends has anyone tried these. any help would be appreciated

I receive my 3520c in August 2022. The set screws in the attached faceplate marked the spindle just behind the last threads. I solved the potential problem by deciding not to use the set screws. I have yet to have an occasion to need the set screws.
 
We have eight 3520B's in our turning studio. When they were delivered, our studio tech removed all of the set screws from the faceplates and hid them. That was eleven years ago, that tech is retired, and nobody knows where they are!
 
I believe anytime u have a new lathe with forward & reverse u will have set screws. My former jet1642 evs has set screws.
 
I use brass set screws and they work just fine. M6 x 1.0 Metric Solid Brass Grub Screws Cup Point Hex Socket Set Screws DIN 916

I am a set screw user. Hopefully the set screws on your other accessories will land behind the spindle threads, but if not, they are easy enough to replace, as mentioned above. If you have an old fashioned hardware store near by, I'd check with them first.
 
A set screw made from or tipped with a softer material would be ideal, but failing that I use a little piece of 14ga copper wire that has been folded into a small coil or disc with long-nose plyers and put that in the whole before i thread in the set screw in. A 6" piece of copper wire would likely produce a lifetime supply of the little copper discs for someon like me. I do loose a copper insert occationally, but they often get deformed enough to just stay in place when the set screw is remove. The copper coils don't seem interfere with the faceplace/chuck threads when the set screw isn't engaged, and I always know where it is so I don't bother to dig them out if they stuck. If they fall out on their own, it just takes seconds to make another. Usually it takes me longer to remember where i put that little stub of romex wire I saved from a past reno.
 
The only time I have had a piece come off the lathe from unwinding was when sanding in reverse and using too much hand pressure. Never had one come off from the lathe braking feature. That ramp down time can be adjusted.
