By holding the cores in place until the entire job is finished, multi-workpiece cutting processes are able to run in an extended, unmanned mode.
High speed cutting with wire electrical discharge machining produces debris in the dielectric at a high rate. Without effective filtration, a wire machine quickly loses its ability to maintain high cutting speed, achieve the desired surface finish and obtain expected dimensional accuracy. Charmilles' approach to solving this problem has been to develop a filtration system that doubles the number of filter cartridges, from two to four.
This wire EDM job shop in Wisconsin acquired a submerged cutting wire machine that lets it handle larger, taller workpieces than just about any other job shop in the country. The new machine has a “column-up” option that adds a riser block between the X-axis saddle and the Z-axis column casting to give it exceptionally tall cutting capacity. The machine was installed in November 2007.
Submerged cutting of large workpieces such as honeycomb seals for jet engines calls for a larger capacity wire cut machine.

Wire EDM units that swivel a horizontally guided electrode wire in a CNC-controlled E axis give this shop the workpiece clearance and flexibility to produce complex, high-precision PCD-tipped cutting tools.
A high speed rotary spindle allows a wire EDM unit to turn round parts with diameters as small as 0.002 inches to a finish of 0.2 Ra while maintaining accurate concentricity.
