Abstract: A cutting unit of a cutting apparatus includes a fixed flange that is disposed at an end portion of a spindle to support a cutting blade and has a plurality of first gas jetting passages on a periphery thereof for jetting gas radially along a cutting edge of the cutting blade, a detachable flange that sandwiches the cutting blade in cooperation with the fixed flange and has a plurality of second gas jetting passages on a periphery thereof for jetting gas radially along the cutting edge of the cutting blade, a cover covering the cutting blade, the fixed flange, and the detachable flange, and a vacuum unit provided to the cover and configured to suck dust scattered inside the cover.

Abstract: A cutting blade is held between a first flange and a second flange to define an annular cutting water supply chamber between the two flanges. The first flange has a plurality of cutting water supply holes, a first holding surface for holding one side surface of the cutting blade, and a plurality of first supply grooves formed on the first holding surface so as to extend in the radial direction of the first flange. The second flange has a second holding surface for holding the other side surface of the cutting blade and a plurality of second supply grooves extend in the radial direction of the second flange. Cutting water is supplied from the cutting water supply holes to the cutting water supply chamber and then discharged from the first supply grooves and the second supply grooves by centrifugal force due to rotation of a spindle.

Abstract: 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.

Abstract: A processing apparatus including an expansible and contractable bellows unit mounted on a workpiece holding unit for covering an area of movement of the workpiece holding unit in a feeding direction and a guide unit for guiding the expansion and contraction of the bellows unit in the feeding direction. The guide unit has an opening for allowing the movement of the workpiece holding unit in the feeding direction and a gutter extending in the feeding direction adjacent to the opening. The bellows unit has a bellows member having one end connected to the workpiece holding unit and the other end connected to the guide unit. The processing apparatus further includes a floating unit for floating the bellows member along the gutter of the guide unit in a noncontact manner.
