A customer in southern Germany processes pump housings and valve bodies made from spheric grey cast and grey cast on 2 processing centers. Processing releases fine particles of abraded cast iron and graphite particles, which contaminate the cooling lubricant. The processing oil had to be replaced after a very few weeks of operation, because the surface quality of the work pieces was degraded as the contamination of the oil increased.
