Replace the EDM process with a high-speed cutting process (Figure)

For the manufacture of injection moulds and models, "Construcciones Mecánicas Solé" decided to use high-speed cutting technology. Not only because this is a company that likes to be unconventional, but also has its inherent logical reasons.

In general, although high-speed molds and model processing are still in the future, the market in this direction must be developed. A typical example of this trend is the “Construcciones Mecánicas Solé” company, an excellent company based in Catalonian, a company that specializes in the production of high-pressure thermoplastic and plastic-resistant injection molds.

From wire cutting machines to high speed cutting technology

Since its inception 40 years ago, the company has been using the latest mold making technology. Wire cutting machines have been used so far – but now high speed cutting technology is being used. By purchasing a Mikron HSM 700 high-speed milling machine, the first step has been taken in this direction.

Processing speed is almost 5 times faster

Starting from the automotive industry, almost all industrial sectors are currently facing the need to increase delivery speeds and reduce production costs. Construcciones Mecánicas Solé's customers in the automotive, household appliance, electronics, textile and cosmetics industries expect the best products and the shortest possible delivery times.

Conventional electrical discharge machining has been unable to meet such requirements. Since the HSM 700 machine (with a speed of 42,000 rpm and an acceleration of 10 m/s) has a very high machining speed, the production cycle is greatly reduced. Parts that used to be processed by the EDM method and took 6 hours to complete are now processed in a high-speed cutting machine, which takes only 77 minutes to complete!

There is also a high performance CAD/CAM system

If programming can also cause bottlenecks in production, what is the use of cutting production time? Therefore, an important factor in the successful use of high-speed cutting technology is to have solid technical support. A CAD/CAM system with a modern state of the art is indispensable. For the Mikron HSM 700, this technical support is provided by the equally complex Heidenhain ATEK HS PLUS CNC system, which is designed for high-speed machining application development centers.

Cavity open-die discharge machining technology in recession

Although the comparison of these two technologies is a complex and (still) controversial topic, cavity open-die discharge machining will undoubtedly be replaced by high-speed cutting technology. This was unimaginable yesterday – but today it has become a reality: modern HSC milling machines, such as the Mikron HSM 700, can perfectly machine hard steel surfaces, usually polished, ground or etched. The processing operation is no longer needed.

Gas Pump

Diaphragm air pump uses compressed air as the power source. For various corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids, they can all be exhausted. The product operation is safe, reliable and resistant. Corrosive, durable, self-priming, idling without damage, a variety of materials, versatile, simple installation, maintenance-free.
