Abstract

The invention relates to the technical field of turning, in particular to a dry cutting method for dry ice cooling. The dry cutting method is characterized in that dry ice is smashed into powder, the powder and compressed air are mixed, and the powder is sprayed on a cutting machining portion of a cutting tool at the same time in the machining process. According to the dry cutting method, the problems of waste of cutting liquid and environmental pollution caused by the cutting liquid in the existing turning process are solved, the temperature of a cutting area is obviously reduced, precision of a machining surface is improved, the service life of a tool is prolonged, and economic benefits in the cutting machining process are improved.

Description

technical field

[0001] The patent of the present invention relates to the technical field of turning processing, specifically refers to a dry cutting method cooled by dry ice, which solves the waste of cutting fluid and the environmental pollution caused by the current turning processing, significantly reduces the temperature of the cutting area, and improves the processing surface. The accuracy prolongs the service life of the tool and improves the economic benefits in cutting. technical background

[0002] During the turning process, the temperature is very high, and the friction coefficient between the tool and the substrate is also large, so cutting fluid is required for cooling and lubrication. Generally, when cutting fluid is used, it is poured continuously and fully, and it must not be intermittent, so as to avoid cracks caused by large thermal stress and damage to the tool; but the economic cost of this is quite high, and the pollution caused by a large amount of cut...
