Investigation of a heat pipe cooling system in high-efficiency grinding

Review on grinding-induced residual stresses in metallic materials

“…A similar intermittent wheel for grinding was also developed by Xu et al [192]. In order to decrease the grinding temperature by enhancing the heat transfer within the grinding zone, Fu et al [193] developed a heat pipe grinding wheel (HPGW). In contrast to the traditional CBN wheel, a significant difference of HPGW is that an annular heat pipe is installed into the grinding wheel, as displayed schematically in Fig.…”

“…As a result, the grinding-induced heat could be quickly transferred from the wheel-workpiece contact zone into the heat pipe and then consumed by means of the evaporation cooling of the inner working fluid. Comparative experiments have discovered that, under the identical conditions, the grinding temperature is controlled below 150°C with HPGW compared with that above 300°C with the non-HPGW during the conventional dry grinding of AISI 1045 steel with a shallow depth of cut [193]. In the creep-feed deep grinding of titanium alloy Ti6Al-4V, when the temperature has reached above 1000°C at which the grinding burn of workpiece happens with non-HPGW, the grinding temperature with HPGW could be still maintained at below 100°C even at the higher material removal rates, as shown in Fig.…”

“…All the abovementioned aspects of the grinding process should be Fig. 24 Heat transfer principle of heat pipe grinding wheel [193] Fig. 25 Comparison of grinding temperature obtained with HPGW and non-HPGW [193] Fig.…”

Health monitoring and diagnosis system for heavy roll grinding machine

“…As the development of performance and process quality of large-scale mechanical equipment, health monitoring becomes an important issue. [1][2][3][4][5] Heavy roll grinding machine is particularly a large-scale mechanical equipment and a typical complex electromechanical integration equipment. 6,7 In the grinding process, the rotation accuracy and stability of the spindle rotation system consisted of headstock, workpiece, and tailstock and has a huge impact on the quality of the machined workpieces and production efficiency.…”
