“…Errors due to the action of temperature deformations range from 30 to 70% in the total balance of processing errors, depending on the size of the machine [13]. The temperature deformation of grinding machine spindle plays an important role in the formation of the workpiece accuracy [14][15][16]. Previously, it was established [15,16] that the amount of thermal displacement of the spindle with a grinding headstock depends on the operating time of the machine tool, the temperature of the working fluid in the bearings, and the ambient temperature and can reach up to 40 µm.…”

Since grinding is a finishing process, the study of the influence of various factors on the accuracy of processing is an important task. One of the main reasons for the occurrence of grinding errors is the temperature deformation of parts and units of grinding machines. This paper is devoted to the experimental studies of temperature deformations of the bed of cylindrical grinding machine tools, resulting from its heating under the influence of various heat sources: namely, due to the friction of parts and units in the drives and guideways of the grinding headstock and table; due to the cutting fluid, which absorbs heat from the grinding zone and sprays to the bed; due to increase of environment temperature. Temperature deformations of the bed were estimated by changing the relative position of the grinding wheel and the table of cylindrical grinding machine, with the workpiece, fixed on it when it was moving during machine tool operation. A comparative analysis of the results of the study of cylindrical grinding machine tools of the same models is done. The maximum thermal displacement of the workpiece points caused of the non-straightness of the table movement due to temperature deformations is given. Experimental data are given on the displacement of the grinding wheel and the workpiece relative to each other depending on the operating time of the machine. In addition, the speed of movement of the control points of the workpiece as a result of the rotation of the table, caused by temperature deformations, are presented. The influence of changes in the ambient temperature during the work shift on the deviation from the straightness of the movement of the cylindrical grinding machine table was also evaluated.
