<p>PURPOSE:To jet cutting water under a high pressure by a method wherein the cutting water from a cutting-water nozzle is jetted, by means of a centrifugal force, along the face of a blade from a slit at the outer circumferential part of a wheel mount via a small hole which connects a hollow to a housing. CONSTITUTION:Cutting water which is pressure-fed is fed into a housing 9 inside a wheel mount through a cutting-water hole 8 made in the radial direction of a wheel shaft 3 and through a hole made in the wheel mount. The cutting water which has been pressure-fed to the housing 9 inside the wheel mount is pressurized further by the centrifugal force of the wheel mount, and is discharged along a blade 2 from a slit formed at the outer circumference of the wheel mount and to a position which is extremely close to the blade.</p> |
