Superfilter ‘talks’ to grinders: General Industry Coverage

END USER: Haas Saw & Supply LLC, (330) 899-8644, www.haassaw.com. CHALLENGE: Effectively clean and cool grinding oil applied in latest-generation grinders. SOLUTION PROVIDER: Comat Technologies Inc., (571) 830-5793, www.comattechnologies.com. SOLUTION: A filtration and chiller system that directly communicates with grinding machines.

When Haas Saw & Supply LLC, North Canton, Ohio, expanded its operation, the company wanted the latest generation of grinding machines to resharpen carbide-tipped sawblades rather than new machines that featured older technology, noted Jim Haas, company owner.

The company, which has six locations and sharpens and repairs circular metalcutting saw blades, uses portable-cartridge units to filter particles down to 15µm from the grinding oil.

“They work, but we know there had to be something better,” Haas said.

He was looking to install a CM 300 and a CMF 300 grinding machine from Vollmer of America Corp., Carnegie, Pa., at Haas Saw’s newest location, Conroe, Texas, and needed the grinding oil filtered to a finer level to maintain the high-quality output and 5µm to 7µm accuracy those machines provide, according to Haas. “We wanted to go to this new generation of grinding equipment because it is light years ahead of the older versions,” he said.

While touring the facility of Julia Utensili spa, Haas saw that the Italian producer of circular sawblades has Vollmer CM machines, but he wasn’t familiar with the filtration technology Julia uses for its grinders. He was informed that it was a Comat Model 2F25 filtration and chiller system from Comat S.r.l., Ossona, Italy. (The U.S. subsidiary is Comat Technologies Inc., Vienna, Va.) “I knew right then that this was the right machine,” Haas said.
