The High-Quality Surface Finishes (HQSF) additive technology from Makino improves finishes using copper, high-grade graphite (Poco-3, AFS), and medium-grade graphite (Poco-2, Poco200). In certain applications, says Makino, HQSF can totally eliminate the need for polishing.

Makino’s HQSF uses an environmentally safe powder additive that is mixed with the dielectric fluid to improve electrical conductivity for more consistent discharging. The additive-based technology has a major impact on finishing time, with a 40 to 50 percent or better improvement of achievable surface finish over conventional EDM sinkers in similar applications.
