Abstract

PURPOSE:To simplify the replacement of a circular saw by constituting the cooler of the circular saw so as to have the movable nozzle arranged in opposed relation to a fixed nozzle so as to hold the circular saw between both nozzles to spray cooling water on the circular saw and made movable with respect to the circular saw. CONSTITUTION:When a hard and fragile material 30 such as a stone material or concrete is cut, a fixed nozzle 21 and a movable nozzle 22 are arranged in opposed relationship so as to hold a circular saw 5 between both nozzles and fixed by a fixing bolt 12. Cooling water W is supplied to the fixed nozzle 21 and the movable nozzle 22 from a hose 7 and a pipe 11 and the circular saw 5 is rotated by a rotary shaft 1. The cooling water W cools the cutting part 5b formed to the leading end of the circular saw 5 and both side surfaces of the saw 5. When the circular saw 5 is replaced, the fixing bolt 12 is loosened to make a movable nozzle holder 9 rotatable. When the movable nozzle 22 is rotated by about 90 deg., the movable nozzle 22 retreats from the moving locus of the circular saw 5 to ensure the moving space of the circular saw 5. When a nut 2 is detached, the circular saw 5 can be replaced.

Next, the operation of the above configuration will be described.
First, when cutting a hard and brittle material 30 such as stone material or concrete, the fixed side nozzle 21 and the movable side nozzle 22 are arranged to face each other with the circular saw 5 sandwiched therebetween, and the fixing bolt 12 is fixed. Then, the cooling water is supplied from the hose 7 and the pipe 11 to the fixed side nozzle 21 and the movable side nozzle 22, and the circular saw 5 is rotated by the rotating shaft 1. The cooling water W supplied to the fixed nozzle 21 and the movable nozzle 22 is
The circular saw 5 is sprayed from a and 22a to cool the cutting portion 5b at the tip of the circular saw 5 and both side surfaces. Circular saw 5 is hard and brittle 3
The heat generated when 0 is cut is transmitted to the disk portion 5a while raising the temperature of the cutting portion 5b, and the cooling water W directly cools the cutting portion 5b and the disk portion 5b.
Since a large area of a is cooled, the temperature rise of the cutting portion 5b becomes a very small value.
