Sinker EDM with Dual Heads



Makino has introduced its EDNC21 sinker electrical discharge machine (EDM) with dual heads that are built to improve productivity and lower the tool build time for large molds. The EDNC21 also includes the Hyper-i control, HyperCut technology and HS-Rib high speed Z-axis.

"As the design complexity of large workpieces, such as automotive bumper and fascia molds, 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, 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."

The EDNC21 offers a work envelope of 122.0" x 70.9" x 39.4" (3,100 mm x 1,800 mm x 1,000 mm) to accommodate large workpieces. The X-, Y- and Z-axes of the machine provide cumulative travels of 78.7", 59.1" and 23.6" (2,000 mm, 1,500 mm and 600 mm), respectively. Each of the EDNC21's gantry-style heads is capable of traveling up to 78.7" (2,000 mm) and is independently controlled and programmed using a dedicated Hyper-i control system for each head. The EDNC21 provides a total workpiece payload of 22,047 lbs. (10,000 kg) and accommodates electrode weights up to 662 lbs. (300 kg) per head.

The design of the EDNC21 includes a programmable rise-and-fall front door for easy operator access during setup and operation. Door height, which controls dielectric fluid level, can be set to match the height of the workpiece while providing optimum viewing of the machining operation.

Every Makino EDNC-Series machine also includes these features:

  • High-mass castings to ensure mechanical and thermal stability
  • Stationary table for accurate positioning regardless of workpiece size or weight
  • Space-saving integrated reservoir in the base casting to reduce machine size and to achieve greater thermal stability
  • Dual-anchored, direct-drive ballscrews that maintain long term precision.

Hyper Technologies

Similar to other EDNC-Series sinker EDM machines, the EDNC21 is designed with Makino's proprietary Hyper technologies, engineered for a mix of speed, finish and reduced electrode wear.

"HyperCut technology is a generator function that increases power levels without requiring additional reduction on the electrode, and it improves roughing speeds by up to 30% without affecting workpiece accuracy or surface quality," said a company spokesperson. "The technology minimizes electrode wear while providing fast machining speed."

Each EDNC-Series machine is equipped with the new Hyper-i control system, which is the same system used on Makino's wire EDM products. Hyper-i improves productivity by streamlining and simplifying the machine interface so that operators of all skill levels can achieve efficient results. Its 24" high-definition monitor provides touchscreen technology similar to that of smartphones and tablets, enabling the use of pinch, swipe and spread movements to select machining conditions for workpiece and electrode material type, and the desired feature shape and surface finish. The Hyper-i control is further enhanced with the integration of on-board digital manuals, intelligent E-Tech Doctor help functions and an e-Learning training system.

Additional Performance Enhancing Technologies

SuperSpark IV: "SuperSpark IV is an advanced adaptive control technology that optimizes the machining discharge power and electrode jump motions during roughing and finishing operations. This technology is effective on rib or drafted electrodes; and, when combined with HyperCut settings, it can reduce total machining time by up to 50%," said the spokesperson.

High-Quality Surface Finish Option: "All EDNC-Series sinker EDMs can be equipped with Makino's proprietary High-Quality Surface Finish (HQSF) technology that yields achievable surface finish capabilities 50% better than conventional surface finishes, regardless of discharge surface area," said the spokesperson. "The HQSF technology can extend tool life through improved surface integrity, and can also reduce cycle time even when fine surface finishes are not required."

High-Speed Z-Axis Option: The HS-Rib Z-axis configuration reduces rough machining speeds of small electrodes, such as plastic injection tooling ribs or pin gate details, and provides enhanced jump speeds of up to 20 m/min that can reduce machining times by up to 60%.
