General Qualities & Characteristics

Gulfway 32, 68 and 220 are specially compounded oils developed for the lubrication of slides and ways and intended to eliminate the phenomenon of stick-slip in machine tool operation.

The special compounding plus the use of highly refined base oils give Gulfway oils outstanding stability, extreme oiliness, adhesiveness and exceptional load carrying ability. They possess excellent metal wetting properties and serve well as rust preventives as well as lubricants. Gulfway oils are noncorrosive to both ferrous and nonferrous metals.
 
Application Requirements
Stick-slip, or the leap-frog motion of a machine tool table on its ways, is most likely to occur when the table is moving slowly and subjected to heavy loads. It causes poor finish and promotes wear. Many modern machines now incorporate resin coated slideways to reduce stick-slip and the use of soluble type cutting fluids is gaining wider acceptance. Gulfway oils are formulated to provide excellent demulsibility characteristics in the presence of water base cutting fluids and have no adverse re-action to resin coated surfaces. Gulfway 68 is classified as a heavy-medium slideway oil and Gulfway 220 as a heavy slideway oil and are approved by Cincinnati Milacron against their current P-47, P-50 and P-53 specification respectively slideway.
 
Recommendations
Gulfway oils are recommended for application to slides and ways of planers, grinders, millers, lathes and NC controlled machine tools to eliminate stick-slip and assure smooth table action even at slow speeds and under heavy work loads. Gulfway 32 is recommended in machine tools incorporating a hydraulic/slideway lubrication system and Gulfway 68 will fulfill most requirements, but where unusually heavy loading or special design features require a higher viscosity, Gulfway 220 is the recommended lubricant. Gulfway oil can also be applied to the bearings and gears of other machinery requiring the special properties of these oils. Gulfway oils have been approved by the major manufacturers of machine tools.
