This included hydraulic oil that was being used in the lube tanks,” said Sherman.


“After years of this we had enough,” said Sherman. “We wanted to standardize on a single oil for cutting all materials as well as the lube side.” About a year and a half ago, Sherman started researching alternatives. One of them was QualiChem Xtreme Cut 764CF, a high-performance straight oil with a medium viscosity, designed primarily for use in screw machines and other automatics. The product is formulated specifically for machining stainless steel, difficult-to-machine high alloy steels, nickel, titanium and specialty high-strength alloys, as well as mild steels, brass, aluminum, and copper alloys, according to Glenn Frank, president of QualiChem. QualiChem’s Xtreme Cut 764CF is 100% chlorine-free. Chlorinated paraffins have been widely used for many years as an extreme-pressure additive in metalcutting fluids, due to their ability to produce high-quality finishes and preserve tool life. The future use is uncertain due to pending EPA actions to restrict the manufacturing and use of chlorinated paraffin.


“We have invested heavily in formulating chlorine-replace- ment technology to meet the needs of customers with chlo- rine restrictions and to be prepared in case the EPA takes action to limit the use of chlorinated paraffin,” Frank said. “When researching options I wanted to get a first-hand look for myself, so I visited another shop that was using the Xtreme Cut 764CF,” Manth Brownell’s Sherman said. “I didn’t talk to the supervisor or president. I went to the floor and talked to the operators. They said nothing but positive things, and told me it was all they ever use. That’s what convinced me to bring it in for a test.” Over the past year, Sherman has been tracking tool life for


different oils and additives with Xtreme Cut 764CF, and has col- lected an extensive amount of data. “QualiChem continues to develop cutting edge technology and has allowed us to test the next generation chlorine-free additives. With every adjustment we keep getting better tool life improvements,” said Sherman. “We started out with tools that were getting 20 or 30 hours at most in tool life cutting 303 stainless, and now those
