CBN grinding on machining centers

[flogrr]

I am asking if anyone has experienced grinding internally on a horizontal machining center with mandrels electoplated with CBN crystals?

I have an application in a thin walled casting made of 15-5 PH stainless steel requiring better than a 32 finish. Any help would be greatly appreciated.

Thank you,
Jesse

If wheel manufactures have a recommended wheel, the only problems might be spindle speed and roundness. You might look at CBN plated honing.

Hope this will help someone in time!

What are the capabilities of your machining center? Wheel Speed? We would take it on faith that the Tool can be rigidly held and positioned, but is this, in fact, true?

What are the required tolerances which you are trying to achieve? Size? Roundness? Cylindricity? Finish? How Measured? Anything else?

Stock removal? Coolant type and application method?

More questions would come to mind after hearing feedback on these.
