M1420 Cylindrical Grinding Machines
M14 series type universal cylindrical grinding machines are used for grinding external or internal surfaces of rotary work-pieces of cylinder and taper workpiece in almost every country all over the world because of the high quality with competitive price.
The longitudinal movement of the worktable is driven by hydraulic or by hand wheel. The worktable can rotate to a certain degree so as to be suitable for grinding taper.
The wheel head cross feed is driven by hydraulic, which realizes automatic periodical feed and rapid feed. It can also do rough and fine feed through hand wheel.
