Abstract

PURPOSE:To enable cooling and discharge of chips to be carried out even when the amount of cooling water is small. CONSTITUTION:When an object to be ground and cut 7 such as concrete and stone materials is ground and cut by operating a diamond wire 1 in which a plurality of diamond chips are provided on a wire, fluid of 4-100-Kg/cm<2> is supplied per 0.2-2m in a part to be ground and cut along the operation of the diamond wire 1. The part to be ground and cut is cooled by the fluid and chips which occur from the part to be ground and cut are washed away by the fluid to expose the part to be ground and cut at all times in order to reduce the amount of cooling water.

2. Description of the Related Art Conventionally, when a material to be ground such as a concrete material or a stone material is ground and cut by a wire saw, the diamond wire and the ground and cut portion thereof are heated to a high temperature due to frictional heat, and therefore, about 2 kg / cm 2 is required. The tap water having a pressure was directly supplied for cooling. Then, at the same time as this cooling, the dust was removed so that the grinding and cutting portion was kept in a flawless state so that the diamond wire could operate smoothly.

Further, when the area of the ground cutting portion is large or deep, cooling of the diamond wire and removal of the diamond are insufficient. Therefore, in order to eliminate the effect of frictional heat and residual dust, the water to be supplied is supplied. It was dealt with by increasing the amount of water as much as possible.

However, in the method for cooling a diamond wire in the wire saw according to the conventional example, there is a limit to the water treatment after cooling in order to cope with the increase in the amount of tap water to be supplied. The amount of grinding and cutting work of the material to be ground by the saw is limited. On the contrary, if the amount of tap water is reduced to increase the amount of grinding and cutting work, cooling and removal of the diamond wire of the wire saw becomes insufficient. For example, in a diamond saw wire wire with a structure in which a diamond tip made by sintering diamond particles is attached to a wire with a plastic or rubber stopper, the plastic or rubber stopper is deformed by friction heat. Then, the diamond tip moves, the grinding and cutting work becomes insufficient, and the residue of the dust causes abrasion of the diamond tip and abrasion cutting of the wire, resulting in a remarkable shortening of the life of the diamond wire.

In order to solve the above problems, a method for cooling a diamond wire in a wire saw according to the present invention is a concrete material, in which a diamond wire provided with a plurality of grinding and cutting blades is operated. When grinding and cutting an object to be ground such as stone material, a fluid of 4 Kg / cm 2 to 100 Kg / cm 2 is supplied every 0.2 m to 2 m in the grinding cutting portion along the operation of the diamond wire, and the grinding cutting is performed. The part is cooled with a fluid, and the shavings generated from the grinding cutting part are washed away with a fluid to constantly expose the grinding cutting part.
It is preferable that the fluid is supplied along the running direction of the diamond wire and at an angle of 2 to 45 degrees with respect to the ground and cut portion of the workpiece to be ground, and the fluid has a temperature of 1 to 25 degrees Celsius. It is good to have a liquid.
