Abstract
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 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
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 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.
Claim 2
Independent Claim
129 words
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 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.
Claim 3
Dependent Claim
44 words
The method according to claim 1, comprising the further step of: eccentrically rotating said rotating plurality of nozzles about a second axis parallel to said first axis, to thereby obtain a more uniform action by said jetted flow on said previously treated stone surface.
Claim 4
Dependent Claim
39 words
The method according to claim 1, wherein: said jetted flow is provide through said plurality of nozzles each having diameters in the range 0.05 to 0.5 mm, at flow rates per nozzle in the range 1.5 to 12 liters/minute.
Claim 5
Dependent Claim
39 words
The method according to claim 2, wherein: said jetted flow is provided through said plurality of nozzles each having diameters int he range 0.05 to 0.5 mm, at flow rates per nozzle in the range 1.5 to 12 liters/minute.
Claim 6
Dependent Claim
26 words
The method according to claim 3, wherein: said plurality of nozzles is rotated about said first axis at a rotational speed in the range 800-4000 rpm.
Claim 7
Dependent Claim
30 words
The method according to claim 4, comprising the further step of: said plurality of nozzles is rotated about said first axis at a rotational speed in the range 800-4000 rpm.
