Reliable, Flexible and User-Friendly technology that matters to delivering exacting productivity
When precision, superb surface finish and low cost per part matter, no job is too big, or too small, for Makino Sinker EDM machines.
Machine highlights: Makino Sinker 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 & tablets, & 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 & e-learning training system.
Productive solutions: 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.
Versatility, Low Operating Cost and User-Friendliness that matter for Optimum Performance and Efficiency
Makino’s new U3 and U3 H.E.A.T. wire EDM machines redefine the expectations of versatility and user-friendliness that matter to the EDM industry. The features and technologies incorporated into the U3 and U3 H.E.A.T. provide optimum EDM machining performance for every application, and further reduce wire consumption and maintenance requirements. The revolutionary Hyper-i control system offers intuitive, interactive and intelligent functions that boost productivity and reduce operator workload. The high-definition, 24” class size touch screen monitor with Smartphone/tablet functionality makes operation extremely easy and straightforward. With on-board electronic manuals, maintenance procedures and video training system, operators have all of the resources they need to be productive right at their fingertips.
The U3 and U3 H.E.A.T. feature a new cutting technology called HyperCut, which provides superior part accuracy and surface finish. HyperCut is capable of producing a 3umRz surface finish with three-pass machining, and represents a 20 percent reduction in cycle time and 14 percent saving in wire consumption when compared to previous technologies. Materials for steel and carbide have been developed and support both sealed and non-sealed flushing applications. The U3 H.E.A.T. also features Makino’s H.E.A.T. (High Energy Applied Technology) technology for unparalleled wire EDM machining speed and accuracy in parts featuring poor or difficult flushing conditions.
Makino has been the industry leader in low wire consumption technologies, dramatically reducing one of the single largest expenses in operating a wire EDM machine. There are no special settings or “part-time” buttons required to experience this saving; every cutting condition, including sealed and poor flush applications, is automatically optimized and designed from the ground up on the Makino for low wire consumption. Together, these features deliver optimum EDM machining performance with an ideal mix of speed, accuracy and wire consumption for the highest level of overall efficiency, throughput and cost. Only Makino can provide this level of performance in every condition and application. The U3 and U3 H.E.A.T. contain a diverse cutting condition library with over 2,200 settings for many material types and flushing conditions from 0.1~0.3mmØ Wires. These settings include optimized conditions for standard hard brass wires, high-speed coated wires and high-taper soft wires. The depth and versatility of the entire cutting condition library ensure that all applications can be machined at optimum productive levels.
The U3 wire EDM machines use a space-saving and highly rigid design. The dielectric reservoir is built into the base casting of the machine, reducing the footprint while improving thermal stability. Part accuracy is further improved with the stationary worktable design, and the automated front-drop door provides excellent access to the machine and workpiece. A dielectric chiller unit, water quality deionization system, transformer and high-performance filtration system are all standard machine features. Makino has also developed a unique Pro-Tech circuit that provides electronic galvanic protection to the workpiece in order to prevent or minimize rusting and oxidation. This unique Makino technology is standard on the U3 and U3 H.E.A.T. machines, and it preserves the integrity of the workpiece without the need for chemicals.
GS-Cut Technology (Reduce belly/bow) One of the most difficult challenges faced by wire EDM operators is the machining of vertically straight workpieces to very close tolerances. Inaccuracies are usually at their worst in the center of the vertical span of a workpiece. These inaccuracies are typically defined as a “belly” or “bow” in the workpiece. Such an error occurs 90 percent of the time during the initial rough-cut operation. The advantage of using GS-Cut Wire EDM technology is that it reduces the belly or bow in workpieces during these roughing operations. By reducing the belly or bow in the rough cut, thus cutting closer to the final net shape, this technology reduces or eliminates the need for additional skim-pass machining.When skim-pass machining is necessary to achieve finer surface finishes, GS-Cut helps to reduce the total cycle time and consumable costs by reducing the amount of error (belly/bow) and remaining material on the final part, thus leading to faster skimming times.
Improved Compensation GS-Cut technology is built into the E-code, so that parameters change automatically with workpiece height. The technology compensates for changes in the wire caused by eroded wear and wire lag. This compensation is done by automatically machining on a slight taper in the rough cut and through adaptive servo movements. The result is that GS-Cut produces straighter and more accurate parts without increased wire consumption. The improvement in part straightness can be as much as 40 percent over conventional wire EDM technology. This reduction in both total cycle time and production costs makes your shop more profitable.
