The quality, precision and ­productivity of the MV1200R and MV2400R wire EDMs are appreciated by Jordan ­Signori (draughtsman), Christophe Boiteux (Managing Director) and Thomas ­Lambert (Deputy Managing Director) of  ITB ­Innovation in Autechaux.

Clamping systems designed to boost productivity

ITB Innovation, a French company domiciled in Autechaux in the Département Doubs near the Swiss border, designs clamping systems for turning and milling centres. It has its own wire EDM machine department comprising two machines, a MV1200R and a MV2400R.

Innovation in the service of productivity

“Thanks to our innovative capability, we have ­managed to gain an excellent position on the market. For many projects, we’re the only company ­capable of ­proposing a technical solution,” the ­management of ITB ­Innovation stresses. The company has ­specialised in the ­development and design of clamping systems adapted to customer needs and component complexity. It works for national and international companies in the automotive, medical and aerospace sectors. Clamping systems are essential for customers, as they enable them to boost their productivity and performance and raise their standard of quality in the production of large and medium series.

Boosting productivity with multi-part clamping

The clamping systems of ITB Innovation are ­capable of handling several blanks at the same time ­(multi-part clamping). The fixtures consisting of solid plates are equipped with the hoses and ­connecting ­elements required by the hydraulic or pneumatic ­systems used for operating the various clamping elements. These are not visible at first glance, as all the ­hydraulic elements are accommodated in the interior of the ­workpiece support. At ITB, the systems are not only fully functional, but also superlatively designed. The ITB team produces numerous standard and customised clamp components.

These differ according to the type of workpiece (turbo engine component, pump housing, aircraft ­component) and call for the use of patented clamping flanges and specially arranged, adjustable stops. This is the only way of clamping parts with high repeat accuracy. When ­surface parts have to be produced, ITB ­Innovation develops and builds clamping systems capable of applying the necessary force so that the part is held in the interior, particularly in boreholes and chambers, with the aid of hydraulically or pneumatically controlled ­expanding mandrels or slides. ITB’s specialists have also developed and built a standardised multi-part clamp for turrets and a zero-point clamping system. The company serves subcontractors, and as an equipper it supplies its equipment to big names in machine tools. For the ­management, the company’s success is mainly attributable to its ­extensive range of products and services. “We ­offer our customers the ideal strategy and a solution that meets their clamping requirements perfectly. Our ­clamping systems are designed to boost productivity. We develop the matching technology, build the necessary equipment, machine the parts and assemble them. Then we test the system as a whole under production conditions and measure and document performance.”

High-precision machining

“Our customers expect our ­clamping ­systems to operate with precision and wear-free in ­hundreds of ­thousands if not millions of ­clamping ­cycles,” the ­management stresses.

Higher speed and precision from the MV Series

For this ­reason, a large number of components are made of ­materials with pronounced resistance to wear, such as tool steel ­Z38CDV5 (corresponding to ­X38CrMoV5 ­under ­DIN). This difficult-to-machine steel permits the fabrication of a large range of products requiring tolerances of the order of 0.01 mm, including components with complex shapes such as T-grooves, rectangular or oval channels and profile guide bores. “Dependable operations can only be ensured with high precision,” the management explains. “This applies particularly to the clamping elements of our patented compact flange. The clamping elements have to be introduced with precision into the channels that have to open with repeat accuracy and high reliability and then close again so that the necessary clamping force can be applied.” The bores required for this process are executed by ITB Innovation with wire EDM. ITB appreciates the advantages of this machining method, as the other possible methods such as hard ­milling do not meet the same precision requirements, in Thomas ­Lambert’s opinion. However, the first wire-cutting machines that were purchased several years ago no longer satisfied the company’s expectations in terms of use, programming and results.

Since the wire-cutting machines from Mitsubishi Electric are easy to operate and highly intuitive, the technicians of ITB Innovation – Étienne Racine here in the ­picture – only needed a few days of training to fully master machine operation.

When technical innovation yields satisfied customers

In the summer of 2014 the company finally decided to invest in wire-cutting machines, choosing the MV1200R and MV2400R from Mitsubishi ­Electric. The selection criteria cited by the company included its wish to ­expand its production capacity and ­benefit from s­pecific ­technical advantages: “The wire ­EDM ­machines of the ­MV Series from Mitsubishi Electric are both faster and more precise than the machines of other ­manufacturers – these are the decisive factors that swayed our opinion during a product demonstration at ­Mitsubishi Electric Europe’s headquarters in ­Ratingen on our business trip to ­Germany.” Thanks above all to the ­generators of the new generation, the machines achieve very high cutting speed. The ­Powermaster system automatically optimises generator performance in ­accordance with the production parameters (workpiece thickness etc.).

To ensure high precision, ITB Innovation operates its MV1200R and MV2400R wire-cutting machines in an air-conditioned room with a controlled temperature.

Highly innovative direct drives with tubular motors, in combination with length measuring instruments with optical data transmission, ensure very high precision. For safety reasons and in its efforts to ensure tolerances under 0.01 mm in the long term, ITB Innovation has set up its wire-cutting machines in an air-conditioned room. The dependability of the ­MV2400R and ­MV1200R machines is confirmed by the management: “With the automatic wire threader, several machines can be operated simultaneously during the day and at night they can run without supervision – an advantage that is worth 4,000 productive hours per year for us.”

In Autechaux in Franche-Comté, ITB Innovation develops, designs and builds innovative clamping systems for complex components, such as aluminium housings.

Outstanding cost-benefit ratio with highly innovative technology

Quick and efficient trainingOn the strength of their thorough ­knowledge of EDM, two technicians at ­ITB ­Innovation were taught at the new machines after attending a brief training event at Delta Machines, ­Mitsubishi Electric’s ­exclusive distributor in ­France. Only a few days later, they were operating the ­machines in production. According to the management, this is largely ­attributable to the ease of operation of the ­CNC ­Advance control’s user interface. The workpieces being machined are programmed in the company by the technicians with the ­ESPRIT software on an external system. Then the data are transferred to the machine via a ­LAN. The operator makes a few additional entries, clamps the blanks and starts cutting. Thanks to the highly intuitive user interface and automatic alignments, these processes can be performed more easily on the wire-cutting machines from ­Mitsubishi ­Electric than on the machines of other manufacturers. Finally, there’s one more ­argument in favour of the MV1200R and MV2400R: “We ­believe that these machines offer the best cost-benefit ­ratio. In our company these machines are particularly ­profitable because they are operated at the same time as other machines and in two work shifts. What’s more, they are equipped with highly innovative equipment. And because we are convinced that innovation is the key to a company’s prosperity, we were instantly impressed by Mitsubishi Electric.”
