SG-R – Power for Precision

Good accessibility thanks to the three-sided lifting tank allows convenient and quick set-up. The precision-ground work table at an ergonomic height is equipped with standard T-slots. For loading by crane, the casing on the top is easily opened.

Rock-solid machine construction, executed with the focus on high precision. A compact design is achieved through the concentrated use of materials matching the traverse paths. The high dynamics of the Z-axis are made possible by the robust design of the machine head.

The worktable of the SG8R is made of granite. Due to low electrical capacitance, it permits precise feedback and optimisation of the generator pulses, especially at low currents in micro-machining. Basically, granite with its special properties ranks as the optimal material for precision machine construction: high rigidity, no internal stresses and a high degree of damping capacity assist precision machining in die-sinking EDM. With its dynamic axis movements and high acceleration forces die sinking requires a rigid machine design – the granite working table supports the precision within the last microns.

Safety always comes first and must therefore already be included in the basic equipment so that you can erode without supervision. The automatic extinguishing system is always included.

The machines of the SG-R series are equipped as standard with linear glass scales in all axes and active temperature compensation – for performance and precision.

Ensures frictionless processes long-term – without downtime, grease nipples or cumbersome grease guns. You can use this time more productively.

… during the live process – without tools or wasted time. Two hands, 32 seconds – and the filter is replaced.

Access to the electrode changer from the front permits ergonomic loading.

The automatic and simple position detection of the electrodes allows you to work precisely, comfortably and quickly.

You can also detect the position of the workpieces with the same convenience as with the electrodes.

The digital Power Master IDPM guided by Artificial Intelligence is the key to the SG-R’s outstanding performance. Minimal wear of the graphite electrodes combined with high removal rates is visibly supported by this technology. The formation of deep ribs with a uniform surface structure is another feature of the new IDPM with AI. The IDPM’s high performance is available not only for the machining of steel but also of carbide.

Significant improvement of the removal rate over conventional machines: up to 40 % higher machining speed can be achieved with carbide – thanks to the new IDPM. The use of copper-infiltrated graphite significantly increases the removal rate. The finish with tungsten copper electrodes compensates for slightly higher wear – performance and precision combined. Also in carbide.

The GV-generator is geared for minimal power loss and thus energy efficiency. This reduces energy costs while at the same time increasing power output and competitiveness – profit-generating technology from Mitsubishi Electric.

The optical industry, microelectronics, medical technology applications – this is where the SG8R is in its element.The clear and distinct focus on highest precision and finest details is reflected in the detailed equipment of this machine system.

No compromising on the generator or technology – even when it comes to the finest details, performance stays at the highest level.

Designed for maximum accuracy and attention to detail, the SG8R has the same high-quality components in its machine engineering as its big sister. No compromises – even when it comes to small loads and short distances. Everything with the focus on precision in detail.

The generator stages for fine finishing with fine currents and high frequencies. NP2 for the finest surface finishes in the range down to Ra 0.1 µm, HGM for high-gloss machining and LLTX for the lotus leaf effect on mould surfaces – all these technologies are supported in their functionality by the SG8R through the low electrical capacitances of the granite worktable. Uncompromising for the highest level of finish.

Response time is decisive

Lower energy input ensures better and sharper edges. Microcracks in the material are minimised at the same time. The improved structural integrity results in significantly extended tool life, not only for forming tools.

Despite its high power density, the technology of the SG series is designed for gentle material machining. Even when machining carbide with high currents in roughing operations, there is scarcely any microcracking. The service life of the machined components is thus significantly extended.

The various units of the generator are adapted to each other in such a way that both a high removal rate and a superlative surface finish can be achieved, especially in carbide. The nano-pulse fine finishing stage produces the most finely structured surface with rapid, fine sparks. Short. Fast. Nano.

Thanks to a special technology, mould surfaces are provided with a texture similar to that of a lotus leaf, which significantly improves the demoulding of plastic components.

The advanced D-CUBES M800 control supports the operator in every situation. It handles routine tasks and takes the effort out of programming. To ensure this, all SG-R machines are equipped with a wide range of networking options: ethernet interface, USB interface, automation interface – full equipment included here as well.

Operating and process data can be retrieved at the control. Available as standard is an export function for all process data, operating states, con­sumption data and maintenance states as well as alarms. This way the data from several machines can be viewed and evaluated in consolidated form, through to their integration in higher-order production man­agement systems.

MTConnect is the offline and license-free communication standard of the machine-tool industry. This standard is supported by many leading software applications for ERP, production management and production monitoring. The SG-R includes the interface on the machine side in the standard equipment supplied.

Anti-virus protection is ensured as standard by one of the world’s leading software systems in security control.

With step-by-step dialogue guidance, less experi­enced users are piloted through the entire process, from programming through to the start of machin­ing. Checklists make it possible to review all process-­relevant settings and machine states so that machining yields the best-possible results without ­interruption.

Greater flexibility thanks to adaptable job planning: with the simple assignment of priorities, you can quickly respond to changing requirements and squeeze in an urgently needed part. Several machining programs can be conveniently managed in the job planner.

Thanks to new algorithms and the use of Artificial Intelligence, machining times can now be calculated much better in advance. The control system “learns” continuously during various machining operations and thus improves the calculated machining times with increasing precision.

A professional wants to know everything – the display shows him all relevant information and enables him to intervene in the live process. This way he has everything under control – and knows that he will always achieve the best results.

The user-friendly and straightforward ESPERADVANCE PRO programming tool can be found on the onboard control and is included in the standard range of equipment. The ESPERADVANCE PRO and ESPERADVANCE PRO lite include an online manual as a technical guide. The SG-R delivers excellent value for money across the board.

Sometimes programming at the machine itself is the fastest and most efficient way to achieve your goal. More often, however, external programming at the PC is the more convenient and effective choice. Ergonomically optimised, without distraction and with all the convenience of programming while the machines do their job.

Boost the reliability of programming at the machine by checking the created program with simulations using Parasolid models. Programming has never been so simple – and reliable.

Programming based on 3D Parasolid, ESPERADVANCE PRO technology programming such as at the machine, 3D graphic simulation for maximum reliability – all inclusive. This option is the right choice for each and every automated die sinking system.

Simple operation via touch screen – just like on a smartphone.

Ready for anything thanks to the extensive library in the control. Only the details of the respective task are still required, and from this the control automatically generates a complete machining program. By selecting the material pair electrode/workpiece, the technology is generated independently. Achieve results faster – for higher output and profits.

Machining programs are created entirely by means of dialogue guidance – at Mitsubishi Electric this is called ESPERADVANCE Navigator. Plain language selection windows guide the operator from set-up and technology selection to program start. Every user, from beginner to professional, will appreciate this.

For a variety of applications, optimised deflection cycles are available that can be assigned on request. You need a cycle deviating from the norm? No problem – cycles can be easily put together with an editor. This is how intelligent operator support works.
