Threads Will Roll: Drilling Performance
Roll-forming taps produce internal threads by displacing the metal under pressure rather than cutting it. This article explains how to perform the operation to achieve good quality threads. Formulas and charts help the user calculate the proper size hole and the size of tap to use for a desired thread.
Tapping Deep Holes: Guide to Chip Evacuation and Tool Life
Deep-hole tapping raises chip evacuation, lubrication, and torque risk. This guide covers practical depth limits, tap selection, and process controls for deeper threaded holes.
Rigid Rules: General Industry Coverage
There are some tapping situations that call for a rigid tapholder and some that call for a length-compensating holder. Often the choice depends on the capabilities of the machine and the CNC driving the tap. This article discusses why a machinist might choose one type of tapholder or the other.
The Good, the Bad and the Retapped
Internal threads can end up undersized because of the work material's properties or because of changes to the hole's dimensions caused by plating or heat-treating processes performed after tapping. This article explains H- and D-limits and how to use them to specify a tap that will produce the right size thread, regardless of any post-tapping operations.
Know What You’re Tapping
Traditional tap/drill charts recommend drill diameters for each size of tapped hole. But, according to this article, these recommendations are based on the size holes that were typically produced by less-accurate tools and processes used in the past. This article suggests guidelines for producing holes that will, in turn, produce correctly sized tapped holes.
Thread Heads: CMM Inspection
Three companies that tap millions of holes annually offer advice for improving the tapping of steel and aluminum. Discussed is coolant application, equipment for tapping and determining speeds. There's also a sidebar on thread milling.
Speed Tapping: Drilling Performance
Tap and tapholder manufacturers have introduced technology to speed up the inherently slow tapping process. This article reviews a number of innovations, including tension/compression holders for rigid tapping, self-reversing tapping heads and quick-change tapholders.
Do you tap or thread-mill?
For many in the machining community, tapping is the preferred method of threadmaking on a CNC machining center. Yet others contend that thread milling is better. Kip Hanson breaks down the long-running argument.
Considerations when having taps resharpened
Resharpening dull taps by hand is probably not a good idea when you could be making parts. Plus, a thorough reconditioning requires a grinder designed for grinding the actual tap form. So resharpening dull taps is one job best left to the experts.
Smarter by design: General Industry Coverage
I'm not a huge fan of machinist's vises. Even with a speed handle and a couple cups of coffee in your belly, it seems like it takes forever to crank them open wide enough to change a pair of jaws.
Racking up ribs: General Industry Coverage
END USER: Prospect Mold Inc., (330) 929-3311, prospectmold.com. CHALLENGE: Reduce the time needed to cut grooves in a large mold. SOLUTION: Replace EDMing with endmilling.
As the Tap Turns: Turning Performance
Tapping isn't easy and one of the toughest challenges is preventing oversized threads. New tools can help. Read these tips from YG-1 Tool Co. and take a look at a 2-minute video of the company's slideshow presentation on multifunctional taps.
