MX – High-End in Oil

Power for Accuracy

The MX series is our only wire cut machine using oil as the dielectric medium. This has different reasons. First of all carbide metal corrodes in water. It absorbs the water and the structure gets sort of washed out. A good example is a combination of cobalt and wolfram carbides. After the cutting process there would be only wolfram carbides left since the cobalt gets edulcorated. Furthermore a big advantage of oil is that the spark gap is smaller than with water which enables a much better surface in terms of roughness and geometrical trueness. The wire-cutting machine itself is decoupled from every possible disturbance. With its own machine feet it can work free from vibration caused by any external units.

With a general positional accuracy of +/- 1 µm, a typical roughness of Ra 0.05 µm and below, a geometrical accuracy of 1 µm and a perfect roundness the MX‘s are made for the following production areas:

  • Micro tools
  • Watch industry
  • Tiny gearwheels
  • Finest blanking
  • Baby-sized components

Mechanical Engineering

Ductile iron. A micrometre away from the future.

The MX600 has a split-axis design, with the table moving on the X and the column on the Y axis – proven for maximum precision with medium loads. The machine’s solid construction providing a firm basis ensures precision for the machine’s entire life.

Decoupled from vibration and heat

The wire-cutting machine stands within a fully enclosed housing – but on its own machine feet. All additional units are arranged on a surrounding floor slab and are fully decoupled from the machine. This eliminates disturbance caused by vibration and thermal effects on the machine.

Even more precise axis movement – whatever the load

The exceptionally heavy-duty machine bed, only the best, top-flight linear guides and precision assembly ensure the best wire-cutting results in the long term. The slides of the linear guides come with play-free bearings without contact between the ball bearings during movement – for maximum smoothness of motion and almost no rolling resistance.

Perfect climate – accurate to the decimal place

Only if you have exact control of the machine, workpiece and dielectric, you do have control of true precision. The inbuilt temperature regulation automatically controls all parameters and synchronises them so as to suppress temperature variation during the cutting process. All for the sake of accuracy.

The perfect drive

Floating on air: no friction, no wear…

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 12-year genuine manufacturer warranty on positioning accuracy is a guarantee of top-level durability.

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

Cutting wire replacement

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

Automatic central lubrication

Makes for smooth running long-term – entirely with­out stoppages, lubrication nipples or cumbersome grease guns. You can now make more productive use of this time.

Changing the power feed contact

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

Perfect drive

What was it about conventional drive systems that bothered developers at Mitsubishi Electric? The need for lubrication, the friction and frictional heat, power consumption, backlash, the cogging moment and above all the possible wear. Only a non-­contact drive overcomes these drawbacks from the outset and is thus an assurance of better results and enhanced dependability over decades.

Speed of light

The Mitsubishi Electric polymer optical fibres have decisive advantages – not only over conventional copper cables, but also over glass fibres. Not only their total resistance to water, but also their high transmission rates combined with minimal space requirements and maximum flexibility are essential for truly progressive EDM systems. The only thing that you as a user notice is the longer service life and enhanced precision.

No disruptive cogging torque

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 – particularly when combined with the specially selected linear guides.

It’s the result that counts. How to achieve it with µm precision.

  • as good as Ra 0.04 µm in ­tungsten carbide
  • in steel < Ra 0.10 µm
  • even and ­particularly where complex ­geometries are concerned

Positioning accuracy all the way

Positional variation less than 1 µm over the entire 300 mm travel path.

Full circle

30 mm circle and 20 mm cutting height with ­precision of 0.73 µm in circularity.

It’s the contour that counts

± 2 µm – maximum dimensional accuracy here ­taking the example of a 20 mm tall component.

Pulse duration: 1 billionth of a second. The royal road to nanoprecision.

Response time is decisive

The lower the energy input, the better and more stabile the cut edges. A larger number of shorter pulses achieve the highest precision ever coupled with good cutting speed – minimising microcracking in the material as a side-effect. The reduced damage in the edge zones and better structural integrity yield much ­extended service life, and not only that of stamping tools.

Extremely low risk of microcracking

The special feature of the MX600’s nPV Generator designed for oil dielectric is its gentle application of energy to the workpiece. Extended tool life for cutting punches and other similarly stressed components is an inevitable consequence.

Good erosion rate and superlative surface quality

The new nPV Generator succeeds in using the same quantity of energy to machine the material while significantly reducing the energy peaks on the workpiece. This is achieved by applying lower energy to the workpiece at higher frequency.

The nPV Generator

The various units of the generator have been ­perfectly matched, making it possible to achieve a good erosion rate combined with a superlative surface finish.

Technology

Automatic wire threading – equipped for any ­situation

Automatic threading in the tiniest bores, even in difficult applications. The innovative flow analysis for the jet stream takes the effort out of your work. The entire process has been optimised to the point where wire diameters of 0.03–0.20 mm can be threaded with absolute dependability.

Round diamond guide

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.

Clamp it and press Start! Precise and simple workpiece measurement.

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 measure the workpiece precisely. With the water flow on, off or in the dielectric – whatever you prefer. By means of the cutting wire or with an optional sensing head.

Fully automatic alignment cycles

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

3D position measuring – manual or automatic

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.
