Thats the story from Cincinna-ti-based LNS America Inc., which produces the venturi, and 168 Man-ufacturing, which sells the FullShop automated coolant management system. A subsidiary of Precision Tool Technologies Inc. in Brainerd, Minnesota, 168 Manufacturing sells automated systems developed and used by Precision Tool Technolo-gies in the manufacturing of its own products.FullShop automatically manages coolant levels and concentrations by sensing them and, when nec-essary, pumping properly mixed coolant to as many as 120 CNC ma-chines. By ensuring that proper coolant parameters are automati-cally maintained, FullShop can be a key part of unattended and lights-out production systems, said ShawnLNS AmericaNelson, sales manager at 168 Man- The venturi is a coolant-saving addition to the FullShop automated coolant management system.ufacturing.
