When precision, superb surface finish and low cost per part matter, no job is too big, or too small, for Makino Ram EDM machines.
All Makino Ram EDMs feature the revolutionary Hyper-i control system, which is the same interface system used on Makino’s wire EDM products, signifying a standardization of Makino’s EDM machine controls. The unique and modern Hyper-i control system represents a paradigm shift in operational efficiency on the shop floor and provides operators with an identical, powerful, user-friendly interface that boosts productivity for both Makino wire and sinker EDM products.
The Hyper-i control system improves machine productivity by intelligently streamlining the interface so that all operator skill levels can achieve the most efficient results. This modern graphical control makes use of pinch, swipe and spread touch functions similar to smartphones and tablets, and provides effective and natural operation using a 24” class hi-definition touch screen. User-friendliness is further enhanced with the integration of on-board digital manuals, intelligent e-Tech Doctor help functions and e-learning training system.
machine provides a level of precision in the sub-micron range, delivering the highest level of surface finish capability that makes it the ideal choice for small electronics and micromachining applications.
machines offer superior speeds and surface finish capability to efficiently handle any task. The EDAF-Series
features a stationary worktable configuration with a rise-and-fall drop-tank design that provides excellent operator ergonomics for part loading and setup and simplifies automation. The design also incorporates the dielectric reservoir into the base casting, which improves accuracy and thermal stability while minimizing floor-space requirements.
machines provide effective and reliable performance for general precision machining applications. The ergonomic machine layout provides open access to the work zone for the operator by utilizing a stationary work table and 4-sided rise-and-fall drop-tank design. The EDGE-Series machines have a compact floor space requirement, as the di-electric reservoir and ATC (Automatic Tool Change) unit is built-in to the base casting of the machine. The EDGE machines also utilize the proven Windows-based MGH-6 control system with touch screen input for effective and user-friendly operation.
offers similar performance, capability and user-friendliness as the EDAF-Series, but in a larger machine platform, with seven different models available to accommodate any size work piece up to 122” x 71” (3.1m x 1.8m). EDNC machines are capable of high-speed jump Z-axis motions up to 20m/min with a 1.5G acceleration rate using the optional HS-Rib Z-axis, making them just as productive and accurate as smaller machines. All EDNC-Series machines have a stationary worktable design. The EDNC6, EDNC8, EDNC10, EDNC15, and EDNC17 utilize a programmable three-sided drop work tank, while the EDNC20 and EDNC21 feature a programmable drop front door.
All machine models can be integrated with automation to increase productivity and maximize unattended operation. All models except for the EDGE-Series utilize the latest advanced Hyper-i control system.
Makino has developed many advanced leading-edge generator technologies that improve productivity and capability. The development of these adaptive control technologies provides enhanced machining speeds while delivering optimum accuracy, uniform surface finish with superior edge and metallurgical quality, destructive DC arc protection and low electrode wear.
This special generator setting provides improvement to machining speeds without increasing electrode wear or required electrode reduction amount. HyperCut can be used on part details up to 30 amps, and improves machining speeds by up to 30 percent without affecting surface quality.
• SuperSpark™ IV:
This family of technologies utilizes dynamic power supply adjustments and jump motion control during the machining process. It enhances automation and unattended operation capabilities by eliminating the need for external flush lines and increases the control’s ability to maintain higher cutting speeds regardless of the application or operator’s experience level. Reduction in rough machining cycle times can be achieved when using SuperSpark™ technology regardless of the shape, size or depth of cavity.
This set of safety-focused settings virtually eliminates the possibility of the machine developing destructive DC arcs during the course of a burn. ArcFree technology, coupled with Makino’s extremely fast servo control response time, enables safe, unattended burning, even when the current applied to an electrode exceeds its maximum current density. While arc prevention has been a part of all modern sinker EDMs, ArcFree technology is the next advancement in intelligent adaptive controls for prevention of DC arcs.
• Flower pattern:
Special conditions were developed to obtain a uniform Ra value surface finish with a large RSm value to improve the performance of mold release for plastic injection tools. The more open structure of the surface finish improves plastic part mold release and tool life while reducing the interval for mold cleaning maintenance.
• HQSF™ (High-Quality Surface Finish):
This optional configuration dramatically improves the produced surface finish of tool steels using copper or graphite electrodes. The technology was specifically designed to eliminate post-machine polishing and produce superior metallurgical results that extend tool life. Makino’s HQSF process uses a special µSC powder additive that is mixed in the dielectric oil that enhances the stability and even disbursement of the machining spark energy. HQSF can also provide cycle time reductions when not machining to ultra-fine surface finishes.
• EDcam™ software:
Makino has developed an off-line programming system for Ram EDM that makes use of the electrode and work piece CAD model information. The system eliminates the requirement of having to create paper process sheets for manual data entry of the programs on the machine control, which invite critical human errors. By intelligently utilizing available electronic data, the EDcam software brings the Ram EDM process into the 21st
century and provides a means of program simulation and verification without the need for time-consuming, on-machine, dry-run operations.
• Remote machine monitoring:
As part of efficient unattended machine operation, operators and supervisors alike may wish to monitor the machining progress while away from the machine. Makino offers two software options that provide a means of process updates. The EDM mail option enables the machine to generate e-mail text-based messages on any alarm/stop status or by timed intervals. The EDM viewer option provides direct viewing of the machine control interface on a remote PC.
