Abrasive Waterjet Type Cutting Apparatus

Abstract

A cutting apparatus includes a fixing table where a position of an encapsulated body that is an example of a workpiece is fixed, and a nozzle from which an abrasive waterjet containing abrasive grains for cutting the encapsulated body is sprayed out. The fixing table includes a plurality of protrusions and a plurality of bases. Each of the plurality of protrusions is partitioned by a groove so as to correspond to a plurality of package products subsequent to cutting of the encapsulated body, and includes a through hole to draw in by suction the encapsulated body or one of the plurality of package products. Each of the plurality of bases links protrusions together aligned along at least one direction among the plurality of protrusions. A region of the plurality of protrusions or the plurality of bases against which the abrasive waterjet collides is formed of a material higher in hardness than the abrasive grains.

1 . A cutting apparatus comprising:
 a fixing table where a position of a workpiece is fixed, and   a nozzle from which an abrasive waterjet containing abrasive grains for cutting said workpiece is sprayed out,   wherein said fixing table comprises   a plurality of protrusions, each partitioned by a groove so as to correspond to a plurality of package products subsequent to cutting of said workpiece, and including a through hole to draw in by suction said workpiece or one of said plurality of package products,   a plurality of bases, each linking protrusions together aligned along at least one direction among said plurality of protrusions, and   a plurality of protection members, each placed in a detachable manner on an upper surface of said plurality of bases so as to traverse said plurality of bases in plan view,   a region of said plurality of protrusions and said plurality of bases against which said abrasive waterjet collides being formed of a material higher in hardness than said abrasive grains.   
   
   
       2 . The cutting apparatus according to  claim 1 , further comprising a mount member provided between said workpiece or said plurality of package products and said plurality of protrusions, and on which said workpiece or said package products are placed,
 said mount member including a material lower in hardness than said abrasive grains.   
   
   
       3 . A cutting apparatus comprising:
 a fixing table where a position of a workpiece is fixed, and   a nozzle from which an abrasive waterjet containing abrasive grains for cutting said workpiece is sprayed out,   wherein said fixing table comprises   a plurality of protrusions, each partitioned by a groove so as to correspond to a plurality of package products subsequent to cutting of said workpiece, and including a through hole to draw in by suction said workpiece or one of said plurality of package products,   a plurality of bases, each linking protrusions together aligned along at least one direction among said plurality of protrusions,   said cutting apparatus further comprising a container in which said fixing table is placed in an interior cavity, and into which liquid ( 91 ) is poured into the interior cavity,   said fixing table being immersed in said liquid so that said abrasive waterjet does not achieve direct collision with said plurality of protrusions and said plurality of bases but achieves direct collision with said workpiece in said container.   
   
   
       4 . The cutting apparatus according to  claim 3 , further comprising a mount member provided between said workpiece or said plurality of package products and said plurality of protrusions, and on which said workpiece or said package products are placed,
 said mount member including a material lower in hardness than said abrasive grains.
