FG duplex filter for use in milling machines

Schäfer Kunststofftechnik GmbH, located in Ortenberg, successfully produces high-quality products from semi-finished plastics: in addition to designed machine claddings of complex construction for mechanical engineering, fancy diffusers for the lighting industry or complex precision parts for laboratory and automation technology, our customer also offers solutions in the field of interior design and advertising technology. Schäfer Kunststofftechnik with its experienced team is a full-range supplier of components, assemblies or end products around acrylic glass, polycarbonate and engineering plastics – no matter if prototype, single part, small series or large serial production.  

Whether in the automotive industry, mechanical engineering, medical technology or plastics technology: machine tools are necessary wherever workpieces are manufactured. In metal and plastics processing, more than 90 percent of cooling lubricants are cleaned today, ensuring a smooth production process.

Challenge

Cooling lubricants minimize the wear of expensive precision machines and make a decisive contribution to the surface quality of the manufactured products. The field-proven double-switch filters from Filtration Group Industrial ensure smooth operation without downtime. The high-performance filters provide the optimum basis for efficient, safe and economical production of high-quality goods, without process interruption during filtration.  

At our customer, the duplex filter is used as a safety filter (police filter for the filtration of cooling lubricant. A pump draws in the cooling lubricant. The fluid runs back through the filter into the spindle via a hose. The duplex filter is installed downstream of the working filter in these applications. It has a safeguarding function and provides maximum safety for internally cooled tools, rotary pressure guides and fine machining bores.

Solution statement

  • On a high-quality 5-axis milling machine, the FG Pi 370 duplex filter with a size of 300 l takes over the filtration of cooling lubricant at Schäfer Kunststofftechnik.
  • The duplex filter ensures reliable operation without downtime. This is because, especially when machining plastic parts with internal cooling of the tool, it is important that the cooling lubricant is free of minute particles, as otherwise clogging can occur.
  • The use of the FG Pi 3730-012 duplex filter ensures efficient filtration and increases the service life of the 5-axis milling machine, ensuring trouble-free operation over a long period of time.

Customer value

  • Low space requirement due to compact design
  • Minimal pressure drop due to streamlined design of components
  • Ergonomic changeover lever with lever lock and pressure compensation
  • User-friendly one-hand operation
  • Guaranteed deposition rates according to multipass test ISO 16889
  • High differential pressure stability and dirt holding capacity of the elements
