Automatic travelling wire electroerosion machining system

摘要

An automatic TW (traveling-wire) electroerosion machining system for machining a plurality of workpieces (2) of different types required to acquire different contours includes a TW machine (15) having a wire setting unit (15k) and located adjacent a predetermined path. A work dispensing unit (9) successively dispenses the different workpieces (2) on to the path from a store (1) thereof located adjacent the path. This unit (9) and a work handling and transfer unit (8) operate under control commands from an NC unit (12) and, in conjunction with the TW machine (15) with the wire setting unit (15k) to carry out a plurality of work processing operations sequentially. In each operation, each individual workpiece (2) selected from the store (1) is transferred as it is carried on a pallet (3) for loading on to and unloading from the TW machine (15). The electrode setting unit (15k) on the machine (15) acts both to form a start hole and thread a wire-type electrode (15) through the formed hole in the workpiece (2). The unloaded workpieces (2) are transferred to an inspection stage for classification into acceptable and unacceptable products.
