Hello, i have question about tormek wheel

Due to fire damage and exposure to firefighting liquids, the diamond wheel I purchased from Tormek has developed rust and stains as shown in the attached photo.Can this wheel still deliver 100% of its normal performance if I continue to use it?Also, is this wheel eligible for after-sales service (warranty/repair)?

I'm sorry to hear about the fire accident.
Unfortunately, it's impossible for me to say how or if the diamond wheel has been affected by the fire.
Corrosion on the surface is not good and will, to some extent, affect performance.
This is not normal operation for this type of wheel.
We would need to examine them to understand how they have been affected by the extreme heat and the chemicals from the firefighting liquids.
I am sorry, but this is not a warranty case.
You should contact your insurance company regarding this issue.
Have a nice day.
