CNC machine tools are praised all over the world because of three major factors: automation, accuracy and versatility. Human (operator) intervention is reduced to minimal levels because CNC machines can run on its own after it is programmed. Also, when the program is perfected, the CNC machine can run the instructions perfectly on its own.

Remember that any CNC machine can also be programmed to do special one-time tasks such as a dry-run, which will help the operator oversee what will happen when s/he leaves the CNC machine to do its tasks alone. Accuracy also goes hand in hand with repeatability. Again, once the program is perfected, the CNC machine can perform that task PERFECTLY even until 7 or 7000 times.

Lastly, versatility also works in the form of “task memory” that these CNC machines have. Once a program has been performed even for just one production run, it can be easily recollected the next time that the company needs the program. This saves time for setting up and loading of different programs.

The CNC sure simplifies the work of thousands of factories and machine shops worldwide. However, no matter how great CNC sounds like, it is something that doesn’t fit in some industries. Like, perhaps, in the cosmetic industry, or in the show-business. Those examples are way too obvious. On the other hand, in these two major mechanical industries, CNC is almost synonymous to “hero”.

CNC In THE METAL INDUSTRY

Think of Metal. Metal. Perhaps the easiest metal that you can imagine is that of…a spoon. Now, imagine ANY spoon done with bare hands. After that, imagine a thousand spoons done with bare hands. It’s so tedious you might even consider suicide if you are assigned to such a job.

The metal industry has been operating on CNC for ages. In fact, if you search CNC in the internet, you will instantly find metal companies topping the list. The major CNC centers that you will find in most metal machining processes are “CNC turning centers”, “CNC machining centers”, “CNC grinding centers” and “CNC drill and tap centers”.

Some of the CNC programs that are connected with the metal industry are milling, drilling, reaming, boring and tapping. Moreover, any metal that has any curved side have experienced some form of knurling, grooving, turning and/or threading.

Fabrication, in manufacturing, refers to processes that are executed on thin plates/sheets. These sheets are cut, punched, and bent to form their finishing shapes. CNC also stars in almost every aspect of metal fabrication.

CNC in THE WOODWORKING INDUSTRY

While the most beautiful wood-worked products are most likely hand-made, you cannot deny that a wide array of tools and furniture HAVE to be NOT hand-made to save time and for mass production levels. There’s just too much work and not to many hands. In light with this, CNC has worked wonders for this industry.

Important woodworking processes include cutting, framing, carving and engraving. The most useful woodworking CNC product is the CNC router table. It is capable of carving elaborate 2D and 3D designs. Moreover, it is also capable of material change while repeating the same design. Since contemporary furniture is often a splash of different materials (e.g. Wood, aluminum and/or plastic), any CNC router is capable of reproducing the same design EVEN in different kinds of materials by just altering the router bit.

Although many local, middle-sized enterprise owners are skeptical about using employing CNC in their manufacturing operations, there have been many success stories to sway them to using it anyway. In the Metal and Woodworking industries, CNC has proven itself time and again to be efficient.

It saves time and efforts in production and (more importantly) back-jobs. If you’re venturing to one of these industries, remember that the word “labor” isn’t something social anymore – it’s technological. And start calling CNC your best friend.
