Sinker EDMs Increase Productivity and Reduce Electrode Wear
Makino releases an upgraded version of the high accuracy EDAF2 and EDAF3 Sinker EDMs with developments that increase productivity while reducing electrode wear.
Makino releases an upgraded version of the high accuracy EDAF2 and EDAF3 Sinker EDMs with developments that increase productivity while reducing electrode wear. The machine features a new heat generator (ES200A) that increases machining power by over 25 percent to a peak power of 100 Amps. The digital generator reduces energy consumption while enabling low-wear electrode technologies that achieve a lower wear ratio, reducing the expense of electrode manufacturing through the use of a single electrode to rough and finish a cavity.
The upgraded series feature the HS-Rib high-speed Z-axis that reaches jump speeds of 20 meters-per-minute with a 1.5 G acceleration. The design utilizes a core-cooled ball screw and closed-loop chiller unit to jump at high speeds while maintaining a 1-micron level depth control. The machine also includes refinement to the auxiliary flushing system, which is digital and programmable and enables precise and consistent fluid flow control for punch machining applications. The combined technologies and performance of the machine’s new generator and Z-axis reduce cycle time of common die/mold rib details with lower electrode wear when compared to conventional technologies.
Strategic acquisitions and diversified capabilities combined with a can-do, inclusive culture take this mold manufacturer to new heights.
Recently, I reconnected with an industry colleague who will bring some international expertise to the states this May to discuss one of the hot topics in moldmaking today: conformal cooling. And, this will be followed up at Amerimold in June.
What can a company do when it has a healthy flow of work running through its facility but a lack of skilled workers to complete it all in an efficient, cost-effective manner? This moldmaker found the solution in two Hurco VMX 42i CNC mills with conversational programming capability.
