Wire Cut

Operating principles

An abrasive thread that moves at a very high speed (about 5.500 mt/min) meets more or less hard materials and like a band-saw it cuts them. The piece that has to be cut is fixed to a pair of pincers attached to a pantograph maneuvered by numerical control (CNC) that enables the direct passage from the autocad design to the cutting procedure.For our case our materials are usually a sandwich of high density rigid polyurethane attached to two expanded rubber sheets.
The joining procedure is done by bonding the parts with an adhesive made of policloroprene. The design of the type of cupels being produced (internal diameter, wall thickness, type of union of the two semi cupels) is done with the aid of an electronic drafting machine and the electronic CAD-CAM. Thereafter the design is transferred to the industrial computer of the wire pantograph and the work is almost done, since the cupels have to be pounced and assembled with the application of an external vapor screen sheathing. The application of the trade label and the packing complete the operation.
