New Cutting Fluids Improve Part Finishes, Surface Speeds And More
After switching to a new cutting fluid, this company not only realizedÌýthe changeÌýprovided better parts finishing, but also longer fluid life, which saved the company money.

Better part finishing is another benefit. The company no longer needs to use an additive or spray cutting fluid to achieve its required finish. This gives machinists more control over the cutting fluid, according to Vaughn Robertson from Melbran Distributing, Inc., the company's supplier.
Finish speed has also improved substantially with the use of cutting fluid. "Our machines are older models, and our parts are mostly small," says one machinist. "This complicates producing good finishes, especially on tool steel. The new cutting fluid allowed us to increase the feed and decrease the spindle-to-floor time by 50 to 60 percent."
The coolant dilution ratio has also improved. The previous coolant ratio was 10:1 or heavier. With Rustlick Ultracut, the ratio has been 20:1, with a ratio of 40:1 used for adding because of evaporation. These ratios have allowed ample rust protection and minimal cleanup on the parts prior to the next process.
For more efficient coolant management, Speer uses Rustlick wheel skimmers to control tramp oils, which are set on timers for easier maintenance. This process, coupled with the use of this cutting fluid, ensures the elimination of bactericide and fungicide in the coolant tanks and machine cavities.
In the near future, the company hopes to switch all 15 of its machines' cutting fluids to Rustlick Ultracut 370R.
