Because of the high requirements on machining methods in metal-cutting production, not only are optimal tools indispensable, but also the optimal accessories needed in production, e. g. cutting oil or lubricants.
The relatively large contact areas between tool and workpiece are decisive for the selection of cooling lubricants. Because of these large contact areas, the pressures between tool and workpiece are correspondingly low. As a result, local heating is significantly lower in honing than in grinding.
In honing, therefore, the flushing action is more important than the cooling effect. For this reason, honing oils are used which have to meet various requirements.
The Flushing Effect of Honing Oil
To achieve a good flushing effect, a large quantity of honing oil must be supplied during the honing process. In order to flush the machining zone on all sides, annular nozzles are installed with multiple outlet points. The honing oil must have low viscosity and be very easy to rinse off in order to ensure that the honing stones retain their cutting ability and remain clean.
