機床的主要特點 Main Characteristics
? 機床機構(gòu)靈巧、精度穩(wěn)定、磨削效率高。工件、砂輪。油泵和冷卻泵分別以單獨電機帶動。
? 配置了液壓驅(qū)動和電氣控制操作方便。具有精巧簡廉特點，適宜于成批及大量生產(chǎn)車間，磨削圓柱形或圓錐形外圓工件。
? 本機床是在M1320的基礎(chǔ)上對其主要液壓部件有壓筒，快速進退油缸、操縱箱、壓力閥板、油泵等作了重新設(shè)計。
? 工作臺面回轉(zhuǎn)角度從順時針3°，逆時針6°增大為順時針 5°，逆時針9°。機床的外形方面也做了較大的改進。
? M1420是在M1320機床基礎(chǔ)上增加內(nèi)圓砂輪軸改型而來，可以磨削一般軸、套類零件的內(nèi)孔。
? With flexible structure, stable accuracy & high grindind effciency.Workpiece, wheel, oil-pump,and coolant pump are respectively driven by their individual motors.
? It has hydraulic drive, electric control for convenient operation. It is suitable for batch and mass production for grinding cylindrical or conical workpieces.
? It is designed on the base of M1320, especially inmroved for its hydraulic cylindeers, rapid advance & withdrawal cylinder control box, presure-valve board and oil pump.
? The swing angle of worktable is increased from C.W.3° and C.C.W. 6° to C.W.5° and C.C.W.9°. The overall appearance of the machine is also improved.
? In model M1420. grinding wheel spindle can be specially used to grind inner bore of shaft and ring type workparts.
