一液压技术在机床上的应用及其优缺点液压技术应用于各类机床上,大体上有以下几个方面:1.进给机构的调速。这是应用液压技术最广泛最成熟的方面。例如磨床工作台和砂轮箱进给;车床、六角车床、自动车床的刀架及转塔的进给;钻床、镗床、铣床、刨床工作台、主轴箱或套筒的进给;组合机床的动力头,动力滑台的进给等。这些进给运动,常常要求慢速工作进给、快速趋近及快速退回。例如YT4543动力滑台,最小工进速度0.0066米/分,而快速进、退速度要求7.3米/分。调速比达1000以上。另外,机床除了无级调
A hydraulic technology in the machine tool application and its advantages and disadvantages of hydraulic technology used in all types of machine tools, in general, the following aspects: 1 feed mechanism speed. This is the most widely used and most mature aspect of hydraulic technology. Such as grinder table and wheel box feed; lathe, hex lathe, automatic lathe turret and turret feed; drilling machine, boring machine, milling machine, planer table, spindle box or sleeve feed; combination of machine power Head, power slide and other feed. These feed movements often require a slow feed, fast approaching and rapid retraction. For example YT4543 power slide, minimum working speed of 0.0066 m / min, and fast forward and backward speed requirements of 7.3 m / min. Speed than the above 1000. In addition, the machine except stepless adjustment
