Our customer

Our client, Bosch, a leading global automotive supplier known for innovation and quality in the automotive industry, required a highly efficient filter system for steel machining. The Bosch manufacturing facility in Wuxi, China, is one of the company’s most important facilities and specializes in the production of components for automotive systems.

The filtration task

A filter system for
the steel machining

The requirement for our customer’s filter system for steel machining is to extend the life cycle of the cooling lubricant used. When machining steel, including turning, drilling and milling, short broken chips are produced and these get into the cooling lubricant. To maintain the quality and efficiency of the manufacturing process, it is essential to remove these chips from the oil. In addition, a solution had to be developed that provides the coolant in four different feed quantities and four different media pressures.

Our solution in detail

Vacuum filter system type FUF FUFAV 9/1500

We have designed a customized filtration solution: A vacuum filter system, also called a vacuum belt filter system, which was specially adapted to the individual requirements of Bosch in Wuxi.

The unique feature of this solution is that the cooling lubricant (oil) is supplied to the processing machines in four different flow rates and four different media pressures:

  • 120 l/min – 40 bar
  • 200 l/min – 80 bar
  • 200 l/min – 3.5 bar
  • 1,240 l/min – 12 bar

To provide Bosch with full flexibility in production planning, three different production modes were implemented. In addition, we were able to meet the customer’s requirements in terms of filter fineness by providing filters with 5 µm and 30 µm.
