Walter USA LLC has announced the latest addition to its Walter Valenite line of ValCool cutting fluids: The VPLFC. The VPLFC is a heavy duty, non-chlorinated, semi-synthetic coolant. What sets the VPLFC apart is its advanced foam control properties which are needed for today's high pressure systems (1,000 psi and up). It has been designed to exceed the most stringent coolant criteria in metalworking.
The VPLFC provides for longer tool life, better surface finishes and reduced consumption. It provides long-term emulsion stability and excellent foam control. Less foam enhances lubricity, a plus in any application but particularly in high speed machining. Further, the fact that it is non-chlorinated helps promote better surface finishes.
Users report that less of the new coolant is used in certain applications when compared to other coolants, while still achieving excellent results. The new VPLFC also helps boost overall system cleanliness, rejecting tramp oils, maintaining stable pH levels, and thus extending the fluid's useful life. It is available in 5 gallon pails to 55 gallon drums.
Related Glossary Terms
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- emulsion
emulsion
Suspension of one liquid in another, such as oil in water.
- lubricity
lubricity
Measure of the relative efficiency with which a cutting fluid or lubricant reduces friction between surfaces.
- metalworking
metalworking
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
