Makino upgrades Z-axis for ribs

Jan. 26, 2015

HS-RIB Z-Axis Head Enhancement This Z-axis column/head for high-speed electrical discharge machining is now offered on Makino's EDNC-Series sinker EDM machines for large pieces with deep ribs, such as injection molds.

What's New? The jump rate is up to four times faster and Z-axis acceleration rate 30 times faster over previous technologies. A more efficient hydraulic effect helps evacuate debris from the spark gap in deep ribs. Z-axis strokes range from 500mm to 800mm. Orbital machining patterns may be programmed without amp limitations. The direct-drive motor and liquid cooling ensure thermal stability and depth control, and supports electrode weights of up to 220 pounds.

Benefits Faster sinker speed for greater efficiency and reduced cycle times. The new capability lets a large, heavy-duty machine like the EDNC85 match the speed of a much smaller sinker EDM.
