摘要： An over or undersize abrasive master mould is used to form tool electrodes by abrading a workpiece using a circular reciprocatory motion. The master mould is made by a casting process which starts with a preformed model, positive or negative, of the exact shape to be machined by the tool electrodes to be made. Positive and negative castings of the model, one of which castings is abrasive, are subjected to a relative circular reciprocatory motion in an abrading operation to provide the correct under or oversize of the master mould, which is then made directly or indirectly from the abraded casting. Casting apparatus for use in the method comprises a pallette for holding the casting and adjusting devices for ensuring parallelity and correct alignment for the moulding faces and there is also disclosed apparatus for the abrading operation in which an error detection system regulates the amplitude of the reciprocatory abrading movement.

摘要： An electrode mounting plate having a flat face adhesively bonded to a graphite electrode and an opposite face forming a trough with reinforcing ribs, the trough being covered in use by the mounting plate of the spark machining apparatus to define a chamber communicating with the dielectric circulation system of the apparatus. Flow passages for the dielectric fluid are formed by drilling holes through the mounted electrode and the flat face of the electrode mounting plate.
