External Cylindrical Grinding Machine（Manual）
Structure：
The left and right guide rail adopts P-V structure, which is scrapeed by high precision manual, so that the whole system products have high precision and high stabiility.
The front and rear feed guide rail of grinding wheel can choose roller and wire rail structure. Classic control mechanism, simple, safe and reliable.
M1350, M1450, M1363 series worktable and grinding wheelguide rail adopts high stable hydrostatic guide rail, high rigid dynamic and static pressure spindle.
Universal workhead can be adjusted at any Angle within 90 degrees couinterclockwise to adapt to chuck grinding internal and external conical workpiece.
