M1420B universal cylindrical grinding machine

Home - Product - Grinding Machine Series

●This machine is an internal and external cylindrical grinding machine. It is suitable for the outer circle of cylindrical or conical workpieces, the outer end surface and the inner hole grinding, especially the processing of various bearing parts.
●The longitudinal movement of the machine table has two modes: hydraulic and manual. The wheel frame and the head frame can be rotated. The outer grinding wheel has a diameter of 400mm, which improves the grinding efficiency and the service life of the grinding wheel.
●The head frame can be moved, the grinding wheel frame can realize micro feed, the hydraulic system adopts low noise special oil pump, the oil supply is stable, the worktable hydraulic reciprocating has the reversing function, and the surface smoothness when cutting the workpiece is improved.
