M7140 Horizontal Spindle Surface Grinder 1000mm 1600mm and 2000mm Table Options for General Machinery Auto Parts High Precision Grinding Machine. Hydraulic longitudinal drive with speeds from 3-30 m/min enables smooth, fatigue-free operation for long workpiece grinding such as mold bases and machine guideways. Four table length options from 1000 mm to 2000 mm accommodate different workpiece sizes, from small die sets to large press plates and jig fixtures. Vertical feed hand wheel with 0.01 mm graduation allows precise incremental downfeed, essential for finishing hardened steel dies and precision gauge blocks. Transverse intermittent feed from 0.5-3 m/min provides consistent crossfeed control for achieving surface roughness Ra 0.63 um on hydraulic valve plates and sealing surfaces. 7.5 kW grinding head motor with 1440 rpm spindle speed delivers powerful cutting for cast iron, tool steel, and carbide materials in general machining workshops. Parallelism accuracy of 0.015 mm per 1000 mm length ensures flatness for machine tool components, linear guide mounting surfaces, and fixture reference plates. Table load capacity from 800 kg to 1380 kg supports heavy workpieces like large injection mold halves and press dies without sacrificing accuracy. Four models with net weights from 3800 kg to 6000 kg provide stable, vibration-free grinding performance for tool rooms, die shops, and production grinding departments.
