Jiffy-TapCutting Fluids and Tap Coolants:Tapping or threading should be done with a good grade of lubricant/coolant. Your local supplier can recommend the best type for the material being worked.
It is best to have the coolant coming out the tap flutes, toward the Jiffy-Tap if possible. This helps to wash out chips which otherwise would load the tap. This is especially important when cutting taper pipe threads because, as the tap is being retracted, chips fall into the threads and are crushed. On many jobs of pipe thread tapping, the coolant can be pumped through the bottom of the hole, and will flow outward toward the Jiffy-Tap. On jobs where this is not possible, the parts should be flooded with coolant to carry away chips and heat and to lubricate the tap. Once each month or every 5,000 cycles put a very small shot of high film strength grease in the grease fitting located on the lead screw nut housing. |
