When processing natural and artificial building materials, it is important to obtain precise cuts and perfect edges (especially when processing ceramic products). A diamond-cutting disc on a metal base can do this job. During high-speed cutting and grinding, a large amount of heat is generated, and the disc heats up to 650 °C and higher. At such temperatures, graphitization of diamond grains occurs, and, as a natural result, cutting stops. In addition, the diamond blade becomes deformed, causing it to jam in the workpiece. Cooling of the cutting disc can be partially accomplished by blowing a boundary layer of air. However, this is ineffective in significantly reducing the wheel’s temperature and increasing the time of continuous operation of the cutting disc. Reducing the temperature of the cutting disc is possible by replacing the air boundary layer with another type of cooling medium. The possibility of replacing the air boundary layer with another type of cooling medium using a Ranque-Hilsch tube was investigated. This allows you to extend operating time by 15%. Cooling the cutting disk with a finely atomized cooling medium (mist) using an ejector tube allows you to create a “new” boundary layer and reduce the disk’s temperature by 25%. These measures allow you to continuously increase the time required to operate the disk.

摘要

When processing natural and artificial building materials, it is important to obtain precise cuts and perfect edges (especially when processing ceramic products). A diamond-cutting disc on a metal base can do this job. During high-speed cutting and grinding, a large amount of heat is generated, and the disc heats up to 650 °C and higher. At such temperatures, graphitization of diamond grains occurs, and, as a natural result, cutting stops. In addition, the diamond blade becomes deformed, causing it to jam in the workpiece. Cooling of the cutting disc can be partially accomplished by blowing a boundary layer of air. However, this is ineffective in significantly reducing the wheel’s temperature and increasing the time of continuous operation of the cutting disc. Reducing the temperature of the cutting disc is possible by replacing the air boundary layer with another type of cooling medium. The possibility of replacing the air boundary layer with another type of cooling medium using a Ranque-Hilsch tube was investigated. This allows you to extend operating time by 15%. Cooling the cutting disk with a finely atomized cooling medium (mist) using an ejector tube allows you to create a “new” boundary layer and reduce the disk’s temperature by 25%. These measures allow you to continuously increase the time required to operate the disk.
