An Impact of Solid Lubrication on the Diamond Grinding Characteristics of Difficult-to-Machine Materials

Sevidova, Elena / Rudnev, Aleksandr / Gasanov, Magomediemin / Kotliar, Alexey / Titarenko, Oksana

The article focuses on the study of the influence of solid lubrication on the characteristic of the process of final diamond grinding (DG) and diamond spark grinding (DSG) of difficult-to-machine materials – hard alloy VK6, titanium alloy VT22, and heat-resistant stainless steel 10Cr11Ni23Ti3MoB. The evaluation was carried out based on the surface roughness parameter Ra and the post-contact temperature T_pc. A comparative analysis was performed for DG and DSG processes using an SL and under dry conditions. It has been established that the use of a solid lubricant (SL) based on stearic acid (65%) and molybdenum disulfide (35%) reduces the post-contact temperature by 1.4… 2.1 times and the roughness by 1.3… 1.6 times with diamond grinding of VT22 alloy and steel 10Cr11Ni23Ti3MoB. SL has a varying effect on the grinding performance of VK6, depending on the parameters of the processing mode. In DSG, the nature of the influence of SL on Ra and T_pc doesn’t change, but their absolute values increase by 1.1…1.5 times. The best results with solid lubrication were achieved on the surface of stainless steel 10Cr11Ni23Ti3MoB – Ra = 0.22…0.39 µm and Ra = 0.38…0.49 µm with DG and DSG, respectively. The results indicated that solid lubrication with a new type of composition has a noticeable positive influence on the surface roughness of difficult-to-machine materials during diamond grinding and diamond spark grinding at the final stage.
