Following tests are conducted for surface grinders :
(a) Table top parallel to its movement by fitting the dial gauge in the stationary spindle and dial feeler touching the table top and traversing the table.
(b) Slots parallel to table movement by fitting the dial gauge in the stationary spindle and dial feeler touching the slot and traversing the table.
(c) Spindle axis parallel to table top by fitting dial gauge on radial arm of the spindle and its feeler touching the square resting on table, and rotating the spindle by 180 degrees.
(d) Spindle axis square with the slots by fitting dial gauge on an arm fitted to spindle and rotating the spindle by 180 degrees.
(e) Vertical movement of spindle square with table top by fitting dial gauge in spindle and its feeler touching the square resting on table.
(f) Practical tests.
