Method and apparatus for refacing an abrasive wheel

Claim 1

A grinding wheel refacer for use in combination with grinding apparatus having an abrasive wheel and a work bed supporting a magnetic chuck; a diamond bit; mounting means fixedly secured to said work bed and adjustably supporting said diamond bit in refacing relationship with said abrasive wheel, said mounting means comprising a mounting head having a bore extending through it, said diamond bit being slidably adjustably disposed within said bore, a finger cavity in communication with said bore, whereby said diamond bit can be adjustably positioned within said bore by extending a finger through said finger cavity to engage said diamond bit, and means for positionally locking said diamond bit at an established position within said bore; a gauge assembly comprising a generally rectangular-shaped member having an offset portion for supporting therein a micrometer means, said gauge assembly being removably secured to said magnetic chuck by the operation of the latter and supporting said micrometer means in operative relationship with said diamond bit such that said diamond bit can be adjustably positioned to engage said micrometer means, said micrometer means being adjustable to establish a fixed determinable dimensional relationship with respect to a work piece to be ground; whereby said diamond bit can be adjustably positioned to reface an abrasive wheel such that the radius of the peripheral face of said abrasive wheel corresponds to the finished dimension of the work piece.
