SURFACE GRINDING MACHINE The axis of the grinding Wheel spindle is horizontal

Vertical spindle surface grinding machine Axis of the grinding wheel spindle is vertical. Work piece are clamped on the circular worktable which is mounted on the vertical spindle The work table is rotated about the vertical axis by motor. There is offset distance distance between work table and wheel.

Speed, Feed & Depth of Cut Cutting Speed: Peripheral speed of a point on the surface of the drill in contact with WP Feed: Distance, the wheel moves in to the WP in mm per revolution. Depth of Cut: Half of the wheel diameter
