Machining slotted rotors?

Halifax · #1 04-18-2009, 06:17 PM

My mechanic told me that slotted rotors cannot be resurfaced.... can anyone verify that for me? I am replacing my Carbotech XP10 pads (with another set of XP10 ... yummy) and I want to go the 'right and proper' route as spec'd by Carbotech and have the rotors cut.

Thanks!

tech is right. the slots won't allow the cutter to work properly.

From a machinists point of view, I don't know why you couldn't resurface them; I've machined parts with an interrupted cut hundreds of times.
And rotors are only cast iron; it's not like they're nasty powdered-metal tool steel or something.

But I don't do automotive work, so I can't say for certain what the reasoning is in this case.
If it's only because they're using a carbide cutter (which can tend to chip because of the interrupted cut), they should certainly be able to use a high-speed steel cutter and avoid that problem.
