Experimental study of double-sided face grinding machine tool

Abstract

The work considers the methodology of experimental studies of double-sided face grinding machines on the criterion of heat stability. The proposed methodology includes: procedure of grinding process simulation; procedure of temperature measurement; procedure of determining the mutual angular position of the grinding wheels due to thermal deformations; procedure of machining error measurement. The described techniques allow you to fine-tune the machine under production conditions. Preliminary full-scale test of a double-sided face grinding machine showed that excess temperatures were distributed nonuniform over the elements of the load-bearing structure of the machine tool when grinding an industrial batch of cylindrical rollers. When idling the end face of the spindle headstocks and bed had the highest excess temperature. When grinding the surface of the machine units, located in the immediate vicinity of the grinding zone, had the highest temperature. The experiments carried out confirmed the coordination of the nature of the change in excess temperatures at characteristic points and cutting coolant when simulating the grinding process on a machine with the corresponding experimental data obtained on a working machine.
