METALWORKING FLUIDS


Regulations, New Alloys Remain Key in Fluids Industry E


nvironmental regulations and use of new alloys and materials continue to be a major concern in the metalworking fl uids industry, both for producers and companies that help recycle fl uid. “Historically, nearly a third of our sales come from prod- ucts that did not exist three years ago,” said Kevin Tucker, product technology and marketing director at Cincinnati- based Cimcool Fluid Technology, part of Milacron Holdings Corp. “We always have new products being introduced.” “Certainly, we see the regulatory environment as a con- tinuing challenge,” Tucker said. “Raw material supply and availability is often a concern as suppliers also continue to look at cost savings. The continuing evolution to lighter, stronger, harder metal alloys always drives the demand for new technology.” Cimcool has provided vegetable-based


fl uids for more than 40 years. The company acquired Starchem Fluids, which led to more vegetable-based fl uid offerings. Cimcool products include the Cimfree line, which are all vegetable-based. A new product line is Cimpulse, introduced in September. The company markets Cimpulse as “one fl uid for all shops and all markets.” Cimpulse 51MP, Cimpulse 45MP and Cim- pulse 33MP are formulated so metalworking shops can use a single fl uid throughout their operations. According to the company, Cim- pulse fl uids have a hybrid blend of lubricants. “Cimpulse Fluids is the fastest growing


“The demand for complete scrap metal and fl uid pro- cessing continues to remain strong,” said Mike Hill, PRAB vice president of sales and marketing. “Metalworking companies and OEMs all recognize the importance of automating the waste management process for recycle and reuse as a means of cutting costs, improving health and safety, and enhancing operational processes.”


The systems PRAB makes for customers vary accord- ing to the type of production process used. “Milling, drilling, tapping, boring and grinding operations have varying profi les of solids and moisture content,” Hill said. “Our standard operating procedure is to run a batch sample of customer-supplied metal/fl uid scrap prior to making equipment recommendations.”


product line we have ever introduced,” Tucker said. Cimpulse originated from the company’s aerospace team. “While most of our fl uids are targeted to very specifi c metals, applications, industries or even duty range, our Cimpulse fl uids are for all customers who only want to stock one fl uid that can do nearly everything.” Tucker said increased regulatory and customer demand


may result in industry consolidation. “It is becoming more diffi cult for smaller companies to meet all of the regulatory and supply requirements.”


Kalamazoo, MI-based PRAB manufacturers systems


to reclaim and recycle metalworking fl uids from processes that generate chips and turnings.

PRAB’s coolant recycling system the Guardian. This version is equipped with a Paperbed fi lter which captures the metal fi nes from the chip processing system and then feeds the dirty coolant into the Guardian. The coolant is clean for reuse after a single pass.


PRAB’s coolant recycle system is called the Guardian. PRAB has added an ozone injection module for its equipment, Hill said. “This type of system typically works for all common types of coolants” such as “water-based, soluble oils, semisynthetic coolants and alkaline cleaners.” Such a unit “is the size of a briefcase and works in conjunction with coolant recycling equipment,” he said. “Ozone is a natural way to control bacteria and eliminates the need for a biocide.”


Hill also said he expects “a continued trend toward


more water-based fl uids and less oil-based fl uids” being requested by customers.
