Abstract
Official abstract text for this publication.
A cutting apparatus includes: a first piping for communication of a suction surface with a first suction source; a branched pipe by which the first piping is branched to an upper-side outlet for passage toward the first suction source and a lower-side outlet for passage toward a second suction source; and a second piping for communication of the lower-side outlet with the second suction source. The cross-sectional area of the branched pipe is set greater than the cross-sectional area of the first piping, such that the flow velocity of a fluid upon transfer of the fluid from the first piping into the branched pipe is lowered. Liquid goes down toward the lower-side outlet of the branched pipe, whereby a gas and the liquid are separated from each other, and the gas is sucked by the first suction source, whereas the liquid is sucked by the second suction source.
First claim
Opening claim text (preview).
What is claimed is: 1. A cutting apparatus comprising: a holding table having a suction surface for suction holding a plate-shaped workpiece; cutting means for cutting the workpiece suction held by the holding table by a cutting blade and cutting water, the cutting water being supplied to the workpiece while the cutting blade cuts the workpiece; and suction force maintaining means for maintaining a suction force of the holding table for suction holding the workpiece, wherein…
