SG-R – Power for Precision

The rock-solid machine base of the SG series is your assurance of precision and durability. The choice of high-class components ensures the long-term reliability of the machine system.

The simplicity of the control and the programming itself – a hallmark of EDMs by Mitsubishi Electric – allows the operator to focus on the essential, i.e. the proper planning of the various eroding tasks. And here, too, this is aided by the intelligent control strategy with integrated job planning and an efficient evaluation of a wide range of operating data, including actual job costing.

The full standard equipment of the SG-R completes the package. A fire extinguishing system, C axis with a zero-point clamping tool, external programming software – all this is part of the standard equipment. Additional useful features enable you to tailor the configuration to your individual requirements.

Mechanical Engineering

1.6 G – 20 m/min

Acceleration of up to 1.6 G and travel speeds of up to 20 m/min enabled by the modern drive unit of the Z axis. The in-house AI technology uses the advantages of these values perfectly. Inclusive of safety: collision protection in all axes.

Precise axis movements – ­whatever the loading

Rock-solid machine build, exactly as it should be. Sophisticated, cleaned up and absolutely durable. These principles are well proven for decades and will be casted into each and every new machine. The use of high-class components inclusive.

In-built „just right“ factor

On the SG-R series, maximum precision is naturally built in – with linear scales on the X, Y and Z axes and advanced temperature compensation, the effects of room temperature fluctuations are measurably minimised.

Ergonomic workplace

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.

Compact

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 – granite for the toughest ­requirements

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 as a matter of course

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.

Linear scales + temperature compensation

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.

Automatic central lubrication

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

Rapid filter change

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

Readily accessible electrode changer

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

Technology

No compromises: everything from a single source

CNC control, generator electronics, axis amplifier, inverter, motors – all from our own production. Reliable technology from Mitsubishi Electric.

The generator. Developed for superlative performance, with plenty in reserve.

The GV generator is designed for a wide range of applications. Superlative performance with extremely low electrode wear by using graphite electrodes is possible as well as the creation of intricate details and high surface qualities with copper. The generator is just as suitable for machining carbides as for machining titanium and many other materials.

External measuring

External presetting on a measuring machine is of course also supported by the Mitsubishi Electric SG-R – for automated operation and maximised profitability!

Probing the electrodes

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

Probing the workpieces

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

KI + IDPM – the key to success

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.

40 % more speed

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 SG8R: tiny, intricate, exquisite. Extreme precision tailored to the finest details.

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.

Short travel paths – robust components

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.

HGM, NP2, LLTX – important acronyms when it comes to finishing

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.

Top-tier technology. Nano precision not only in tungsten carbide.

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.

Microcracks in carbide? No thanks!

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 nP Circuit

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.

LLTX lotus leaf technology

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.

Connected into the future

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.

Process data management

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 interface

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.

Safety first

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