Companies like bearing maker use many grinding machines, then by-produce a lot of grinding sludge, most of which is dumped into landfills now. Being ISO14001-certified company, it is responsible for helping establish recycling technology and contributing to our recycle-based society. Report of "No. 2 Development of practical machine and test results" proved that it was possible to separate coolant from grinding sludge economically and grinding swarf and coolant were able to be reused for environmental load reduction at practical use level after one year long run test. But it was found that there were many kinds of sludge which were similar to grinding sludge but impossible to separate coolant from sludge with the same method of grinding sludge separation. For further environmental load reduction, honing sludge was picked up for the next target. Basic test proved that it was possible to separate coolant from honing sludge by adding paper filters to the method of grinding sludge separation. Based on those test results, practical machine was developed and it was confirmed that it was possible to achieve recycling and cost-reduction at the same time for honing sludge also.
