Abstract
A vacuum suction device comprises a vacuum suction plate formed by baking a porous material and having a flat suction face for holding a workpiece by suction; a base abutting on a bottom of the vacuum suction plate for supporting the vacuum suction plate and having a plurality of suction grooves in a part of a surface of the base abutting on the bottom of the suction plate, the suction grooves being coupled to a pipe of the base; an intake device coupled to the pipe of the base; a peripheral member formed of an airtight material for encircling the suction plate; and means for preventing a grinding liquid from getting into the vacuum suction device through the suction grooves. The preventing means prevents reduction in suction force applied by the intake device acting on the workpiece.
