The Importance of Cleanliness in the Machine Shop

Whenever you ask someone how to produce a hole in a piece of metal or wood, the automatic response will be to employ a drill. In the end, this technique has been taught in metalwork and engineering classes up and down the nation for decades. However, sometimes a typical twist drill is not the answer. Depending on the material, it could cause the surface area round the hole to dimple or burr that could ruin the complete project. An annular cutter is really a tool that's often used in place of a regular drill because it has the ability to cut an ideal hole without damaging the rest of the material. Reamers may also be used to make minor adjustments/enlargements to the hole.

While twist drills are still a standard way of drilling holes, they have major flaws that have been picked up on by engineering companies in search of perfection. Its point is really two cutting angles which intersect causing the phenomenon referred to as the'dead zone '. The situation with this specific'dead zone'is that it forces the speed of the edges to grind to a halt. This drop in speed causes great inefficiency in the cutting process and makes it harder for the edges to push through the top of the material. If pipe or tubing has been drilled, the lack of speed results in increased drill pressure which in turn causes the material to dimple Annular Cutter.

The key reason why an annular cutter is more successful in this instance is really because it's hollow and therefore doesn't suffer from the'dead zone'problem. When this is with the undeniable fact that the cutting edges are out at the edge it means that the speed of the drilling remains the exact same throughout the procedure. When using this bit of machinery, always make certain that the speed at which it cuts is kept at a advanced otherwise the edge will dull. In many ways, this is the opposite of the metal hole saw which goes blunt when its speed setting is consistently too high.

Reamers are successful when it comes to making minor adjustments to a hole. Once you try to tackle too big a job, the reamer can be ineffective and be in peril of being damaged. If your reamer is being used, it should not be put in reverse as this is actually the quickest way to blunt the cutting edges. Whoever has ever taken an executive class in school may have seen this machine stuck in a lathe or drill press. Before it is turned on, the work piece must be held rigidly by a chuck or vise for safety reasons.

As you can see, twist drills are not the only piece of equipment that will create holes and alter them. An annular cutter will give you an infinitely more accurate hole and will not be marred by unsightly dimples. Reamers will help you well if you decide a hole is not quite the best size and needs a minor adjustment. Keep clear when working with both sets of equipment must be slight mistake is all it requires to make a mess of previously good work.
