COOLANT AND CUTTING OIL RECOMMENDATIONS

COOLANT: All operations may be performed with soluble oil, 1 part to 50 parts water, applied as a spray mist.
Tapping is done with "TAP MAGIC" or equivalent.

CUTTING OIL: NOT recommended when machining copper alloys except on screw machine operations where it performs as a coolant and lubricant. To prevent metal oxidation, finished parts MUST be cleaned with a detergent-type solvent.

GRINDING RECOMMENDATIONS
Silicon carbide and aluminum oxide wheels can be used, with the aluminum oxide wheels preferred for MoldStar™ alloys. As a general rule, the selection of the grinding wheel is best left to the wheel manufacturer, since so many variables must be considered. Emulsions of soluble oil and water are satisfactory grinding fluids.
