主要用途
本機(jī)床為寬砂輪無(wú)心磨床，主要用來(lái)磨削直徑為10~200mm的各種軸承外圈表面以及相類(lèi)似的其它各種等直徑零件的外表面，如活塞銷(xiāo)，氣缸套，活塞，短軸等，適用于大批量的通磨磨削。機(jī)床又具有自動(dòng)切入機(jī)構(gòu)及機(jī)械手的液壓和電氣控制系統(tǒng)，因此配備必要的機(jī)械手上下料裝置和其它專用裝置后，機(jī)床也可作切入成形磨削，如羅拉，錠桿等成形零件的磨削。
Application
The machine is a centerless grinder with wide grinding wheel,mainly used for grinding various shafts with a diameter of 10-200mmThe outer surface of bearing outer ring and other similar equal diameter parts,such as piston pin, cylinder sleeve,Piston,short shaft,etc.,suitable for large-scale through grinding.Machine tool also has automatic cutting mechanism and machineryThe hydraulic and electrical control system of the hａnd is equipped with necessary manipulator loading and unloading device and other special equipmentAfter setting,the machine tool can also be used for cutting in forming grinding,such as roller,spindle and other shaped parts grinding.
