Complex BvL cleaning line allows comprehensive pre-cleaning and fine cleaning
Combined cleaning process for Russian engine manufacturer
The individual requirements of different production lines require a high level of flexibility when designing the suitable cleaning solution. BvL Oberflächentechnik GmbH from Emsbüren in Germany developed a complex machine system for use in a new production line of a Russian vehicle manufacturer. Thorough and comprehensive pre-cleaning and fine cleaning in the automated production of HGV engine blocks is ensured in sequential cleaning stages.
Two BvL cleaning systems are used at separate positions in the overall production process. After the cast engine block is machined at the upstream machining centres, any swarf, cutting fluids and drilling emulsion are removed in a “NiagaraFS” spray cleaning system. Then the external “Nevada” vacuum dryer ensures complete drying. Pre-treatment of the components at this quality level allows precise further machining, fine machining and initial assembly at the downstream stations without delay.
A complex BvL system of machines can then be found at the end of the production chain, combining several steps in one system. First, the so-called “Geyser” system uses high-pressure lances specially developed for this application to deburr the very small drilled holes with a pressure of 700 bar. During the automated further transport, the engine block is then transported into another “NiagaraFS” system, where the oil channels are additionally cleaned with a 35 bar spray process to remove swarf, oil and cutting oils. A downstream “NiagaraDFS” then ensures external cleaning of the entire engine block in a spraying and flooding process. Once again, further transport leads into a “Nevada” for separate, efficient vacuum drying, with the chamber pressure reduced to as low as 3 mbar. At the end of the cleaning process, an “Arctic” cooling tunnel actively cools the components to a temperature of 25 °C before the engine blocks subsequently undergo a leak tightness test.
At the EMO trade fair in Hanover from 18 to 23 September 2017, BvL Oberflächentechnik GmbH will in particular be presenting the options for combining a variety of different cleaning processes in different size versions.
