Coolants Promote Long-Term System Life without Water-Insoluble Residues
Chemetall, the surface treatment business unit of BASF’s coating division, offers its Tech Cool 35058 and Tech Cool 35037 metalworking coolants.
Tech Cool 35058 is a machining fluid developed specifically for applications requiring superior micro-finish on ferrous alloys, low- and high-carbon steels, titanium, molybdenum, and tough alloys. It is low-foaming and formulated to run longer in high-velocity central systems. The product offers corrosion protection, contains no chlorine, sulfur, boron or phosphorus compounds, and is compatible with ferrous and aluminum alloys. The fluid applies a blend of additives that is said to deliver extended sump life. Tech Cool 35058 is recommended for use in most medium- to heavy-duty machining and grinding applications.
Tech Cool 35037 is a general-purpose machining and grinding fluid developed for applications requiring efficient and economical performance on copper alloys and aluminum. It too is low-foaming and designed to deliver good finishes for aluminum drilling and tapping applications. Like the Tech Cool 35058, it offers corrosion protection, extended sump life and contains no sulfur compounds. Its lubricity is activated by a chlorinated EP ingredient. Tech Cool 35037 is completely free of formaldehyde-releasing biocides.
Both formulas exhibit enhanced hard water tolerance and increased emulsion stability, the company says. The in-service cleanliness of these products promotes long-term system life without the formation of heavy, tacky, water-insoluble residues.
Bacterial growth in metalworking fluids eventually leads to machine downtime. Furthermore, shop owners and plant managers see an increased cost of purchasing replacement fluids and the disposal of spent fluids.
With their strong attention to routine housekeeping, it's not surprising that this shop carefully researched all methods for removing tramp oil from coolant in machine sumps. If tramp oil is allowed to build up in the coolant, the resulting shop odor, smoke generation and unpleasant conditions for the operators will quickly undermine all efforts to keep a clean shop and maintain an optimum working environment.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
