MV-R Series – Power for Precision

The Tubular Shaft Motor converts energy directly into motion, without contact, without maintenance and above all without loss of precision – long-term. Combined with the 400% faster fibre-optic-­based control, this superior technology can truly show what it is capable of.

The positioning accuracy even of the large MV2400R is < +/- 2 µm over the entire travel path – there’s a genuine 12-year manufacturer warranty for this on all Mitsubishi Electric EDM systems. An assurance of top-level durability.

Your company’s technological edge has a name: ­Tubular Shaft Motor – from world market leader ­Mitsubishi Electric.

…for communication by fibre optics.

The Tubular Shaft Motor with its highly responsive control fully exploits the benefits of high communication speed. No heat, no maintenance and no contact – just extra precision for good. At Mitsubishi Electric, this is known as “Changes for the Better”.

Set-up, programming, maintenance etc. – all the key elements are directly accessible at the front of the machine. The entire wire feed, automatic wire thread­­ing and wire guide heads plus the whole workspace are readily accessible – not least thanks to the open design and automatic vertical sliding door.

A considered and far-sighted approach is the best safety policy – but what if things have to be done in a rush? An intelligent EDM system that spots and prevents possible collisions contributes to safety at work and saves annoyance and time.

…so that you have direct access. This saves time and space and makes workpiece set-up that much easier.

Simply replace the spool and feed the cutting wire over the feed rollers. Everything ready for work again in 92 seconds.

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

Replace the power feed contact with just one hand and a small gauge – at a speed befitting ­Formula One.

Maximum precision and durability ensure the best results in the long run – inclusive of maintenance-­friendliness due to a small number of parts and simple design.

The wire-cut EDM systems from Mitsubishi Electric constantly check current axial forces and thus fully ­automatically detect potential accidents before they happen. If there is an obstacle in the travel path, this is electronically detected on the basis of the drive’s load change during the approach and the control ­automatically reverses. Better safe than sorry!

You’re surely familiar with the cogging torque ma­n­i­fested by a conventional electric motor. It is precisely this cogging torque that is undesirable, as are variations in torque. The Tubular Shaft Motor – the optimal drive for precision applications like electrical discharge machining.

Response time is decisive

An EDM machine that reacts with greater speed and precision achieves better surface quality faster. The new V350 generator has a significantly higher effective clock rate. The voltage is built up faster and with greater precision thanks to reduced capacitance loss. Thanks to faster voltage build-up, spark duration and working voltage can be lowered. All that you will probably notice is higher surface quality and lower power costs.

The proven digital fine finishing generator (D-FS) is also optionally available for the MV-R Series.

The Power Master Control gives the most highest level of process stability – whatever the shape being cut. Stepped workpiece shapes, boreholes and other obstacles to a stable cutting process are identified as soon as they appear and the control adopts cutting and flushing parameters for a safe process and superlative accuracy.

On small inner and outer corners and complicated geometries, Corner Master 3 comes to your aid. You merely define your priorities, and optimisation is performed accordingly.

During roughing, a bridge is controllably created to hold the waste material – the waste material cannot fall. In this way many features can be rough-­machined and, after removal of the waste material, recut – fully automatically and unmanned, overnight and at weekends. Lower costs, higher profits.

The number and length of fixing points are easy to set in different ways: directly via a comfortable dialogue menu within the CNC or on external programming systems supporting this function.

Standard core connections are replaced by easily removable fixing points, thus reducing the manned time for picking up core parts dramatically. Instead of cutting off the material bridges slowly, the core can be easily removed from the workpiece with slight manual pressure to the core, so the finishing process can start sooner. Remarkable time saving in detail help to reduce overall processing time, contributing to higher process efficiency.

The ergonomically designed, intelligent manual control box unites all the relevant functions for control and set-up in a single unit. The integrated LCD display can be individually configured by the operator. Inclusive of buttons for driving all 8 possible CNC axes.

Intuitive operation from the large screen with modern gesture control boosts comfort, while the configura­ble user interface supports the user by allowing the main functional elements to be freely arranged dur­ing daily work.

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.

The easy-to-grasp display of all the key machining parameters in configurable form keeps everything under control at all times. Clearly visible at a glance are – if desired – machining status, elapsed times, state of maintenance and other data. Configuration couldn’t be simpler.

During the preparation of pending machining tasks, support is provided by overviews of the remaining wire, state of filter cartridges and deionisation ­resin, and other parameters. This way you can prevent ­outages caused by finite consumables or wear parts and optimise machine running times.

The complete machine documents inclusive of maintenance instructions are always available, and the right help is quickly found. Comprehensibility is aided by photos and 3D depiction.

If time is of the essence or you want the machines to take some of the work off your shoulders. Set-up often takes too long; from now on, you can save this time.

Highly accurate probing cycles on the sides and ­corners measure the workpiece precisely. With or without jet stream or even submerged, by means of the cutting wire or with the optional 3D touch probe – just as you wish.

Intelligent user guidance takes you to the finish. The electrical discharge machine takes you quickly to your goal.

Comfortable set-up with the manual control box: standard equipment with Mitsubishi Electric. All essential control functions at hand – wherever you need them.

Both are possible. As a user, you decide whether you do set-up classically by hand or the machine automatically defines the position of your workpiece. Using the cutting wire or pick-up coil – the machine takes care of it for you. It only takes the press of a button.

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

This is the easy way to add new jobs during machin­ing or change the order of existing machining op­er­ations. The new job processing system with priority management makes it possible to amend a machin­ing list without interrupting machining.

A machining process is easy to pause even in mid-flow when urgent jobs have to be processed. The control stores the current state of machining. When the inserted job has been completed, machining can be immediately resumed at the point of interruption. Pushbutton flexibility without programming effort.

All the key consumables are monitored online and presented with their anticipated remaining life. This includes display of the remaining life of the wire spool installed in the machine as well as indication of filter pressure and, calculated from this, the prob­able period until the next filter change.

Machine states depicted over time make capacity utilisation easier to grasp and assist forward-looking production planning. This overview is supplemented by a list of completed machining jobs and the associated machine times and unit costs.

Given knowledge of unit costs and their inclusion in the machine’s own analysis, records of consumption data such as energy consumption, wire consumption and component wear help with cost analysis and the costing of pending machining jobs.

Rapid online help to reduce downtime and expenditure on service assignments. Applications support with ­direct access to the machine control can provide the machine operator with optimum and rapid assistance when faced with difficult tasks. All in the aid of improving production operations.

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.

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

You can control the machine and keep an eye on processes, wherever you are. ­Intelligent communication takes the pressure out of work. Ideal combined with automation solutions and high process autonomy with the intelligent AT wire threader.
