Makino Europe High-speed Z-axis head enhances speed and efficiency in large sinker EDM applications
Germany – For improved speed, lower electrode wear and more uniform finishes in large sinker EDM processes, Makino has recently introduced its new HS-Rib high-speed Z-axis technology.
When it comes to reducing sinker EDM cycle times, it is not the maximum jump speed that is important, but rather the acceleration speed, the company explains. According to the company, the high-speed Z-axis technology has a jump rate four times faster and a Z-axis acceleration rate 30 times faster than previous technologies. This capability is said to produce a more efficient hydraulic effect during machine processing, which helps evacuate debris from the spark gap, even in deep-rib features.
“As with all machining processes, there’s an insatiable desire to reduce cycle times while meeting part-quality requirements in sinker EDM processing,” says Brian Pfluger, Makino’s EDM product manager. “Fulfilling these needs involves a number of considerations, including how to process for best speed and efficiency, minimise electrode manufacturing requirements, and reduce electrode wear to achieve the best possible surface finish quality. Our new high-speed Z-axis technology, combined with Makino’s SuperSpark IV, helps support these factors, providing an ideal balance for efficiency in both electrode consumption and cycle times without the need for external auxiliary flushing.”
The high-speed Z-axis technology is available on all Makino EDNC-Series sinker EDM machines, and is designed for use in large workpiece applications requiring high accuracy and fine surface finishes, Makino says. Its design is said to offer highly flexible processing capabilities, including a jump rate of 20 m/min with 1.5-G acceleration.
