摘　　要：以机床磨削超细硬质合金为研究对象,对磨削加工时各种运行状态下的功率、不同磨削参数下的磨削比能及磨削有效加工能效进行研究。结果表明:空载运行的功率占据了磨床总磨削功率的92%;磨削比能es随砂轮线速度vs的增大有小幅度增大,随磨削深度ap和工件进给速度vw的增大而减小,其中vw对es影响最大,ap次之,vs最小。磨削有效加工能效η随vs、ap及vw的增大而增大,其中ap对η影响最大,vs次之,vw最小。因此,为了降低磨削能耗,在实际磨削加工超细硬质合金时,应尽量缩短载运行时间。在保证加工质量的前提下,应选择较大的ap和vw。For the grinding of ultra-fine cemented carbide,the machine tool energy consumption was investigated through the power at various operating states and grinding parameters.The influence of grinding parameters on grinding energy consumption was characterized by grinding specific energy es and grinding effective energy efficiencyη.The results show that the idle power accounts for 92%of the total grinding power of the grinding machine.The es increases slightly with the increase of wheel linear velocity vs,and decreases with the increase of the grinding depth ap and the workpiece feeding speed vw.The vw has the greatest influence on es,followed by ap and vs.Moreover,theηincreases with the increase of ap,vs and vw,respectively.The ap has the greatest influence onη,followed by vs and vw.In order to reduce the grinding energy consumption during processing,the idle time should be minimized.Meanwhile,under the premise of ensuring machining quality,a larger ap and vw should be adopted during grinding the ultra-fine cemented carbide.
