Tapping technology No need to ‘tap out’ when it comes time for threading holes

Many machinists would prefer not to wrestle with taps due to the problems associated with the cutting tools. YG-1 says surrender shouldn't be an option, and the South Korean supplier outlines the concerns while offering technology to give mould makers the upper hand.

It has been said that tapping is one of the most difficult machining operations because of the problems of chip removal and lubrication at the cutting edges and the fact that speed and feed cannot be varied independently because the relationship between them is fixed by the lead of the tap.

In the production of thread holes, the type of tap used is the most important factor to be considered. Typically, tapping is performed at the final operation of parts machining; a misapplied tap can ruin a part that already has significant amount of value added to it.

The other thread cutting tools, like single point turning tools, often remove material in time-consuming multiple passes to attain the targets – dimensions, surface finish, and so on. On the other hand, multiple passes are impossible in tapping. The tapping cycle is completed when a tap fully advances and retracts from hole.
