Abstract
Apparatus and a method are provided for working and finish-treating the surfaces of stones by jetting a flow consisting solely of water, at a pressure of 200 kg/cm.sup.2 or more, toward the stone surface which previously may have been cut by a gang saw or a circular saw cutting machine, bush hammered or dabbed finished, bush hammered and then dabbed finished, bush hammered and then flamed or directly flamed without being bush hammered so that the surface of the stones is roughed and crystal particles in the stones are exposed.
Claims6
A method of working and finish-treating a surface of a stone, comprising the steps of:
- at least one treatment selected from a group of treatments consisting of gang saw cutting, circular saw cutting, bush hammering, dab finishing, and flaming;
- jetting a flow consisting solely of pressurized water directed at the stone surface, at a pressure not less than 200 kg/cm.sup.2, through a plurality of nozzles generating jets that respectively overlap adjacent jets;
- rotating said plurality of nozzles about a first axis to produce corresponding rotation of respective jets therefrom;
- and
- translating said stone surface relative to said rotating jets at a rpedetermined spacing therefrom, said jetted flow thereby removing gangue from the surface to leave a finished stone surface which is close to a natural stone surface.
