Abstract
A non-toxic coolant/lubricant suspension is provided which is specifically designed for use in extremely high-load, high-stress machine operations, such as broaching. The composition of this coolant/lubricant includes about 1 to 15 wt % of molybdenum disulfide (MoS.sub.2) powder; about 1 to 7 wt % of soap flakes; about 6 to 12 wt % of a liquid polytetrafluoroethylene suspension; and about 66 to 92 wt % water. The liquid polytetrafluoroethylene component, which is a water-based suspension of polytetrafluoroethylene, serves as a replacement for toxic CCl.sub.4, which has been used to increase lubricity in coolant/lubricants comprising molybdenum disulfide. The replacement of CCl.sub.4 with liquid polytetrafluoroethylene in the present composition results in a non-toxic but still highly effective coolant/lubricant. The coolant/lubricant is a stable suspension, which permits it to be used in recirculating systems in which the coolant/lubricant is recovered, filtered, and re-directed onto the broaching tool and/or workpiece.
