Honing with polymer based cutting fluids

It is currently not possible to omit cutting fluid in honing processes due to the relatively low cutting speeds and the planar contact between workpiece and honing stone and the therefore needed flushing capability for chip removal. Resource efficiency can be maximized during the honing process by replacing mineral oil based honing oil with an alternative fluid. In this study grey cast iron was honed under the application of honing oil and mineral oil free cutting fluid, henceforth referred to as polymer dilution. The obtained results showed that the polymer dilution leads to higher achievable specific material removal rates with concurrently lower surface roughness compared to the application of mineral based honing oil.
