產(chǎn)品簡介

本系列機(jī)床為兩軸聯(lián)動CNC高精密數(shù)控外圓磨床,選用SIMENS、FANUC或其它數(shù)控系統(tǒng)。工作臺及砂輪架的運動分別由Z軸和X軸上的交流伺服電機(jī)驅(qū)動滾珠絲杠完成。X、Z軸聯(lián)動實現(xiàn)直線和圓弧插補(bǔ),完成斜面及圓弧的磨削。通過合理編程,本機(jī)床可完成各種中小型零件的圓柱面、圓錐面、軸肩等單面或組合面的磨削。可以進(jìn)行砂輪成型修整,實現(xiàn)成型磨削。該產(chǎn)品除滿足諸如汽車、摩托車、壓縮機(jī)、汽車變速箱、油泵油嘴、閥芯閥桿等傳統(tǒng)行業(yè)的外圓柱面的精密磨削加工外,也適用于諸如立體打印之膠輥、陶瓷、半導(dǎo)體等等新興行業(yè)的外圓柱面的精密磨削加工。

結(jié)構(gòu)特點STRUCTURAL FEATURES

機(jī)床布局為工作臺移動式T型布局,工作臺左右運動(Z軸)及砂輪架橫向運動(X軸)皆采用伺服電機(jī)帶動滾珠絲杠驅(qū)動結(jié)構(gòu)。
潤滑采用間歇潤滑泵進(jìn)行集中潤滑,頭架為死結(jié)構(gòu),尾架工件手動頂緊、松開,頂緊力的調(diào)整可通過調(diào)整彈簧的壓緊量來實現(xiàn),砂輪架為片瓦的動承結(jié)構(gòu),磨削剛性好,精度高。
工件磨削可實現(xiàn)數(shù)控編程自動磨削 ,滿足大部分中小零件的自動磨削加工的要求,可以很好的替代傳統(tǒng)手動式外圓磨床,降低機(jī)床對人員操作水平的要求,-名工人可以同時操作多臺機(jī)床,提高了工人的生產(chǎn)效率。
The layout of the machine is the movable table t-type layout, and the leftright movement of the table (z-axis) and the transverse movement of the wheelhead(X- axis) are driven by the servo motor and ball screw.
Lubrication by intermittent lubrication pump for centralized lubrication ,The workhead is a dead center structure, and the tailstock workpiece is manually jacked and released. The adjustment of jacking force can be realized by adjusting the com-pression quantity of the spring. The wheelhead is a dynamic bearing structure of tile, which has good grinding rigidity and high precision.
Workpiece grinding can realize CNC programmed automatic grinding, which can meet the requirements of automatic grinding of most small and medium-sized parts. It can well replace the traditional manual cylindrical grinder, and reduce the requirement of machine tools for personnel operation level. One worker can operate multiple machine tools at thesame time.
