Chemtool Inc. announces NuSol 21 MW. The new metalworking fluid incorporates a proprietary process that promotes high productivity and minimal downtime for the user. NuSol 21 MW is a suitable replacement for general-purpose synthetic and semisynthetic metalworking fluids in machining and grinding applications and in central systems.
NuSol 21 MW is formulated with a preformed emulsion, based upon a high viscosity, high molecular weight hydrocarbon base stock that provides superior boundary lubrication. And the small particle size provides a very durable and uniform lubricant film, enhanced cooling, a clear running fluid, and exceptional hard water stability.
Features of NuSol 21 MW:
- Very low VOCs/eliminates odors
- Excellent corrosion protection for tooling, equipment and parts (even in hard water)
- Exceptional lubricant film for good tool life and quality finishes
- Extremely small particle size for superior wetting and excellent hard water stability
- Rapid tramp oil separation for cleaner system operation
What makes NuSol 21MW different from other fluids? “NuSol 21 MW is unique in the industry. It has preformed micro-emulsion of very high viscosity oils and is much more stable. This makes it less subject to biodegradation in the sump. It also has better film strength and is meant to be a ‘fighting grade’ fluid for general machining of cast iron and steel," said Mark Warnock, fluids technical manager.
"It is a simplified formula that is specifically beneficial for job shops. It’s an inexpensive, high-performance fluid with all the benefits of the NuSol line," he added. "It has excellent heat removal and low carry out, so there’s less fluid loss (and replacement). NuSol 21 MW is a high productivity fluid for the end user. The customer uses significantly less fluid over time. They also lessen downtime by not needing to shut down their machine to clean windows, the machine tool itself, change the fluid, or the sump as often (since the fluid does not biodegrade as rapidly, and is off-white to translucent—making it much easier to see the machined part through the window).”
NuSol 21 MW is compatible with cast iron, carbon steel, tool steel and aluminum alloys, has a refract index multiplier of 3.5, high-pressure capability, is all metal safe and is excellent for milling, turning, sawing, drilling, reaming, tapping, OD/ID/centerless grinding and tube bending applications.
Related Glossary Terms
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum alloys
aluminum alloys
Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.
- emulsion
emulsion
Suspension of one liquid in another, such as oil in water.
- film strength
film strength
Relative ability of a fluid to form a film between workpiece and tool, under the influence of temperature and pressure, to prevent metal-to-metal contact. See lubricity.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- 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.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- sawing
sawing
Machining operation in which a powered machine, usually equipped with a blade having milled or ground teeth, is used to part material (cutoff) or give it a new shape (contour bandsawing, band machining). Four basic types of sawing operations are: hacksawing (power or manual operation in which the blade moves back and forth through the work, cutting on one of the strokes); cold or circular sawing (a rotating, circular, toothed blade parts the material much as a workshop table saw or radial-arm saw cuts wood); bandsawing (a flexible, toothed blade rides on wheels under tension and is guided through the work); and abrasive sawing (abrasive points attached to a fiber or metal backing part stock, could be considered a grinding operation).
- tapping
tapping
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
- tramp oil
tramp oil
Oil that is present in a metalworking fluid mix that is not from the product concentrate. The usual sources are machine tool lubrication system leaks.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
