The odorless coolant is said to offer increased removal rates, lower electrode wear, excellent surface qualities, lower refill quantities and longevity to provide lower overall operating costs.
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.
