  • Publication number: 20210162608
    Abstract: A processing apparatus includes a table base to which a jig table is removably secured, a cutting unit, a moving assembly for moving the table base between a processing area and a mounting/dismounting area, and a delivery assembly for delivering the jig table from a temporary rest area onto the table base while applying a negative pressure to a second suction channel of the jig table. The delivery assembly includes a pair of grippers for gripping both sides of the jig table, a suction pipe connected to the second suction channel of the jig table that is gripped by the grippers, and a lifting and lowering unit for positioning the suction pipe selectively in an operative position where the suction pipe is connected to the second suction channel and a lifted position where the suction pipe is spaced from the second suction channel.

  • Patent number: 10297488
    Abstract: A workpiece support jig includes a support plate supporting a workpiece on a first surface while covering a support surface of a chuck table with a second surface opposite to the first surface and a retainer plate including an area sufficient to cover the whole of the workpiece and sandwiching the workpiece, held on the first surface of the support plate, between the support plate and itself. The support plate includes a plurality of groove parts corresponding to projected division lines of the supported workpiece and a plurality of through holes formed in chip-holding regions demarcated and divided by the intersecting groove parts. When the workpiece divided by a processing unit into chips is unloaded from the chuck table, the workpiece is unloaded while being sandwiched between the support plate and the retainer plate.

  • Publication number: 20160271835
    Abstract: A cutting apparatus includes a holding table for holding a workpiece, a feeding unit for moving the holding table in a feeding direction, first and second bellows connected to opposite ends of the holding table in the feeding direction, each of the bellows having an upper wall and opposite side walls adapted to be expanded and contracted for covering the feeding unit, a pair of drain channels provided along the sides of both bellows for receiving cutting water used in cutting the workpiece, and a scrap receptacle provided at the downstream end of the first bellows in the feeding direction for receiving scraps generated from the workpiece in cutting the workpiece. The cutting apparatus further includes a pair of fall prevention plates provided along the pair of drain channels for preventing scraps scattered onto the upper wall of the first bellows from falling into the drain channels.
