M7130B/M7140Bx20surface grinders

DESCRIPTION

These machines are to be hydraulic-controlled for longitudinal travel while the grinding wheel head can be automatically operated or simply by-hand for more efficient movement vertically with an additional speed-up-down device．Be applicable to working kf various spare parts，such as machine processing，car accessories，work tongs and clamping tools，magnetic steel and molding tools，etc…
