Makino’s EDNC21 electrical discharge machine enables simultaneous processing of multiple fine details.
Makino’s new EDNC21 dual head sinker electrical discharge machine (EDM) is designed to lower the tool build time for large molds.
It includes Makino’s proprietary HyperCut technology and HS-Rib high-speed Z-axis, improving roughing speeds by up to 30 percent and reducing machining times by up to 60 percent compared to the previous generation.
Inside the EDNC21
The new EDM offers a work envelope of 122.0” x 70.9” x 39.4” to accommodate extra-large workpieces, such as automotive bumper and fascia molds. Its X-, Y- and Z-axes provide cumulative travels of 78.7”, 59.1” and 23.6”, respectively.
Each of the EDNC21’s gantry-style heads can travel up to 78.7”. The heads are independently controlled and programmed using a dedicated Hyper-i control system. The stationary table supports a total workpiece payload of 22,047lbs. and each head accommodates electrode weights of up to 662lbs.
A programmable rise-and-fall front door offers easy operator access during setup and operation. The door height controls dielectric fluid level and can be set to match the height of the workpiece.
Processing Intricate Features with Maximum Throughput
“As the design complexity of extra-large workpieces continues to grow, manufacturers must identify new means for processing a wider variety and volume of small intricate features with maximum throughput,” said Brian Pfluger, Makino’s EDM product line manager.
“The dual-head configuration of the EDNC21 enables shops to process multiple fine details in a workpiece at the same time, significantly reducing total processing time. Due to its rigid and precise construction, the EDNC21 is capable of achieving the same level of accuracy and surface finish as sinker EDM machines one-tenth its size,” Pfluger added.
