Question Can cross drilled rotors be turned

I don't know how it happened but my 5000 miles old Brembo cross drilled rotors on my Supra TT needs to be resurfaced,steering wheel shake on applying brakes ? My question is since they are pretty new would i be able to get them resurfaced at a machine shop or just throw them away and get another set ?
Feedback appreciated.
Thanks

They can be cut, but some shops will not do them.

All that's required is small cuts to reduce the cutting blade chatter as they pass over the holes.

I have done the rotors on my 930 once myself.

Instead of turning them on a lathe, disc rotors should have their surface ground down.

How exactly do you grind the surface ?
Ruf930,
Good to know they can be resurfaced.
Thanks

The shop that you bring the rotor to should have the correct machinery for grinding rotors.

if you believe the "rotors don't warp" theory, then it's just the accumulation of material on the pad.
