Greased Proper coolant lubricity helps smooth cutting performance Lightning

摘要

The downtime associated with replacing cutting tools during a metalcutting operation is one of the most significant production costs. Cutting back on speeds and feeds can extend tool life, but it reduces productivity. To extend tool life without sacrificing production, machinists must reduce the friction and temperature in the cutting zone. Applying the right metalcutting fluid with the appropriate additives plays a major role. To meet part specifications, the surface finish must not show symptoms of wear adhesion that can result when temperatures are too high. Moreover, dimensional tolerances must not be adversely affected by thermal expansion. The lubricating properties of a metalworking fluid reduce surface friction between the workpiece and the cutting tool and serve to contain heat generation and control temperature levels in the cutting area.
