The influence of hard lubrication on the processes of diamond grinding (DG) and diamond spark grinding (DSG) of hard-working materials - hard alloy VK6, titanium alloy VT22 and heat-resistant stainless steel 10H11N23T3MP was studied. The conditions of the performed experimental researches are described. The evaluation was performed according to the parameters of the surface roughness parameter Ra of the postcontact temperature Tpk. It was found that the use of solid lubricants (SL) based on stearic acid (65%) and molybdenum disulfide (35%) reduces 1.4… 2.1 times post-contact temperature and roughness 1.3… 1.6 times with diamond grinding of alloy VT22 and steel 10Х11Н23Т3МР. At DSG the character of influence of SL on Ra and Tpk does not change, but their absolute values increase in 1,1… 1,5 times. |
