Abstract

The article deals with titanium alloys with anti-corrosion resistance, structural strength and refractoriness, as well as case-hardened carbon steel 12X2H4A.

The high chemical passivity of titanium surpasses that of the best grades of stainless steels. These properties are present to varying degrees in various titanium alloys, which leads to a high demand for this group of metals in various industries. Titanium alloys are obtained by traditional alloying of pure titanium with additional metals and minerals, which makes it possible to obtain materials with different physical and chemical properties at the output. Aluminum, nickel, copper, iron, chromium, vanadium, etc. are the main alloying elements in titanium alloys.

The object of research is the process of flat and round grinding of a titanium alloy and carbon case hardened steel, namely, the cutting microforces that occur during grinding. One of the most problematic places in the work is the selection of the necessary grinding modes, grinding wheel and its grain size. In the course of the research, samples of titanium alloy VT8 and steel 12X2N4A were used. They tested the grinding process with circles of cubic boron nitride (hereinafter referred to as CBN).

The results of this study make it possible to predict the performance of the grinding wheel, to minimize the energy costs of production, and also to refine the parameters of the part processing mode to obtain the necessary indicators of the quality of the surface layer and the geometric dimensions of the part.

The purpose of the study is to experimentally, using a CBN grinding wheel, to establish the patterns of change in unit cutting forces in the process of microcutting when grinding specimens from titanium alloys and carbon case hardened steel.

Keyphrases: Microcutting., crack resistance., microtemperature., titanium alloy grinding.
