Coolants & Lubrication Systems

As demand grows for finer surface finishes and tolerance specifications become tighter—and competition continues to intensify—parts manufacturers are adopting advanced fluid filtration technologies to achieve their machining and grinding goals.

Cortec VpCI-649 BD combines contact and vapor-phase corrosion inhibitors to protect metal surfaces in direct contact with the treated fluid, as well as those areas above the level of the fluid where the contact inhibitor cannot reach. As the inhibitor flows along in the liquid stream, it releases a corrosion inhibiting vapor that adsorbs and forms a protective layer on exposed metal surfaces above the level of the fluid.

After helping customers to remove tramp oil from coolant for more than 40 years, Jim Petrucci, vice president of Oil Skimmers Inc., has yet to hear from anyone that doesn't have at least some tramp oil present in an individual machine sump or large holding tank. When enough tramp oil seeps into coolant on a steady basis to justify the acquisition of oil-removal equipment, which is common, the Cleveland-based company offers oil skimmers to remove surface oil.

Clean coolant in carbide and HSS tool grinding is important in creating a safe work environment and is partly responsible for the quality of the end product. VOMAT GmbH from Germany provides fine filtration systems that separate dirty and clean oil 100 percent with their full flow filtration process. The filter throughput and backwash cycles are automatically adjusted as needed. This extends the life of the filter elements and saves energy and costs.

Adopting a modern fluid reclamation system can provide quick ROI while improving profits, equipment lifespan and employee safety.

When regrinding tools, clean filtered coolants are an important quality factor. The filtration system manufacturer VOMAT from Germany ensures that clean and pure cooling lubricants are available for an extended period of time to the production process. The compact VOMAT FA 70 is particularly suited to tool regrinding.

Klüber Lubrication introduces Klüberplus Z 01-006 US, a water-based solvent containing wetting agents, corrosion inhibitors and degreasing compounds.

In connection with the article I'm writing about metalworking fluid filtration equipment for our March issue, I spoke with Irvin Kaage, president of Transor Filter USA, Elk Grove Village, Ill. The company provides the One Micron Filtration system, which removes particles larger than 1µm from oil, primarily for grinding.

EXAIR's 1/2 NPT internal mix 360 degree hollow circular pattern atomizing spray nozzle atomizes fluid and sprays away from the nozzle in all directions, up to 13 feet in diameter. These nozzles are ideal where a liquid application is needed in a broad area, such as dust suppression, humidification and cooling.

A former NFL linebacker, Pete Shufelt credits his post-football career as the owner of Backerworks Manufacturing LLC to the day he asked his high school counselor/football coach about what elective classes to take.

By using CO2 as a process coolant, the cost-efficiency of machining can be significantly improved. With its quattroClean system, acp has developed a solution suitable for use in serial productions.

In the ninth episode of the CNC Chef, Bob Warfield of the CNCCookbook covers the role of coolant in CNC machining and offers some tips for using coolant more effectively.
