If a tap doesn’t create the hole, why is the hole size so important?
As an experienced machinist will tell you, threading holes is the last thing you master in this craft. Why is that so?
1. Drilling and milling are usually easier.
2. Threading the hole is usually the last operation on a part.
Let's look at one variable: Hole size.
Generally, for 60 degree threads, the percentage of thread should be 75% as a rule-of-thumb. That seems to be a
Emily Torres is a rising senior at South Beloit High School. She signed up to participate in a job shadow program with North American Tool and several other local businesses. The students (including Emily) were exposed to various aspects of the companies they worked with over a two week period.
The shadowing program was organized and sponsored by South Beloit High School’s College & Career Center. The program is funded by Hendricks CareerTek. “The goal moving forward is to allow participating youth to gain valuable experience in the trades” says Tina Salzman, Business & Education
Marcus Schellinger, a rising senior in a Rock County High School (WI) on track to graduate at the end of the 2019-20 school year has spent the last six weeks working at North American Tool in South Beloit, IL. Marcus had to take the initiative to apply online to the Rock County 5.0 program (in its second year) a part of the Rock County Economic Development Committee.
Marcus was assigned to work a CNC Mill and a CNC Lathe in the Bar Steel A department of NATC. This is where the making of a tool
What tap should be used for deep holes with extra thread length? Why do some applications cause a “No Quote" or “No-Guarantee on Performance” response?
From the perspective of a tap manufacturer, the general rule is that any thread length more than 1-1/2 times diameter is considered “excessive”. It’s a good rule in terms of tap performance. Acceptable strength of thread as determined by length of fastener engagement might best be illustrated by the thickness of an Industry-Standard nut as assigned to its mating bolt. That functionality between nut and bolt seems to have had
If you have a shop (or a customer) that machines aluminum and aluminum alloys as its go-to substrate, why are you selling/buying general purpose tools?
You are working with the most popular-to-machine material. How does your company stand out from your competitors who machine aluminum? Isn’t the advantage of aluminum that it is already free-machining and more desirable to work with in the first place? Isn’t it likely your competitors have reached the same conclusion? If you are using general purpose tools, you are likely getting similar results to your competition. Here’s a suggestion on
If you deal with exotic alloys like Inconel, titanium, Hastelloy, etc., this blog post is written especially for you.
Exotic alloys are alloys designed for high temperature applications (think aerospace), perform in corrosive environments (think underground), or have the highest strength to weight ratios (think earth moving applications). The machinability of these materials is NOT the first consideration. As much as it would be nice to have an aluminum firewall in a helicopter from the machinist’s viewpoint, as the pilot or passenger you want flame retardant and strong.
Some exotic materials can
When discussing Screw Threads, it may be helpful to understand a little of the history behind them.
Let’s start with helical forms. Records dating to around 250 BC establish that it was Greek mathematician Archimedes who explained the mechanical principle of the screw as a form of wedge. He went on to formulate the mathematical characteristics of a helix. This was a precursor to the invention of the “water screw”, which provided a means to move water for irrigation, and as a method for ships to evacuate bilge water. It is apparent that other great

Most cutting taps are available in three chamfers. Taper, plug and bottom are how they are referred to in most of the current literature. Why do we choose one over the other and what are the advantages?
Unlike a drill or center cutting end mill, taps introduce the cutting edges by means of a chamfer. Drills are cutting on the tip (axial), center cutting end mills plunge (axial) then may traverse to cut radially on the workpiece. Most end mills are cutting on the radius, but they are to leave a “straight” or “smooth” finish.
