Grinding/Drilling Granite

(OP)
Looking for some idea how to calculate power requirements for grinding and drilling granite.  Looking to grind 1/4"-3/8 bevel around rectangular granite block (4" thk) and also drill  up to 12" dia hole using standard hole saw.  Speed is whatever is considered typical for granite.  Thanks.

RE: Grinding/Drilling Granite

IDR (Industrial Diamond Review) is a magazine that covers a lot of this.  Try them for referrals for diamond products.

RE: Grinding/Drilling Granite

hi,
look my mr.,i know that drilling brittle materials like granite must be on low speeds relatively.....and it must be done on a machine with very low and damped vibrations..........a 12'' hole.......if the ratio between length and diameter of hole is more than 1:2 so that where the problem starts...and obviuosly there is no problem......the problem will be in fixation and vibrations.
