The automobile, camera, arms and aerospace industries were some of the first to use CNC machining. In the case of aerospace industry, they were able to tap on the ability of CNC machines to manufacture lightweight parts with very tight tolerances, allowing aerospace components to be made even out of the most difficult materials. These include fuel access panels, engine mounts, landing gears, engine housing, turbine wheels, plates and other parts.
CNC machines are also regularly used in the automotive industry to make parts of gear boxes, valves, cam shafts, brake discs, engine blocks and cylinder heads, pistons, and body panels. Beyond these, electronic items and even dashboard panels and headlights could be produced by selecting the right CNC machine tool.
CNC machining is highly valuable to the medical industry. This is due to its complexity and ability to machine parts to very tight tolerances, ensuring accuracy in making high precision surgical and equipment components such as X-Ray machines, scanners, microscopes, and transfusion equipment. Even human spare parts made out of materials such as titanium hip joints, knee caps, teeth implants, and bone screws can be manufactured with high precision CNC machines.
The oil & gas industry is another heavy user of CNC manufacturing techniques. With their wide range of uses, CNC lathes or machining centers can be used for fabricating precise and reliable parts such as connectors, pumps, pipes, Christmas trees, drilling tools, casings, shafts, cylinders, and valves.
CNC machining is also widely used as an indirect manufacturing process to create molds & dies. Molds will be injected with molten plastic or filled with liquid casting material to form machinery parts. Dies, on the other hand, will be injected with aluminum or other materials to create products in large quantities. All molds & dies are machined with utmost precision by CNC machining centers.
CNC machining applications are also used in other industries such as the semiconductor, construction, ship building, and wind power industries. Even common items which you use daily are bound to have components produced by CNC machines &#; these include smart phones and IT products, home appliances, sport shoes, washing machines, vacuum cleaners, and remote controls.
CNC machining is a tried and trusted method of metal fabrication used for countless projects every day. Nearly anything that requires engineering or planned design most likely involves CNC machining in some way. All kinds of industries and businesses need quantities of large and small metal and plastic components that may become part of anything from automobiles to zoos.
If you&#;re reading this on a computer or handheld device, it probably contains something created by CNC machining. If you drive a car or have machines in the garage, they are likely to have components produced with CNC machining. The process started in the s and has since grown to encompass a multitude of metal fabrication applications.
There is much to gain from learning about the CNC machining process and how it can benefit your unique business application.
CNC refers to computer-numerical control machining, and it automatically operates machine parts including lathes, routers, grinders, shapers, mills and more under the control of a computer instead of a human operator. Compared to manual operation, CNC machining reaches an exponentially faster and more precise level of production through multitasking. The process employs several axes at once to accomplish the jobs.
The computer controlling the machine is not your average desktop computer. CNC brains are located in a console and programmed with &#;G-code&#; written especially for CNC machining. The code contains elements that enable control over feed rate, coordination, speed and position. The code also helps produce precise, consistent parts that end up as products or building blocks of products.
CNC machining involves exact, high-speed movements that enable expedited production, customization and several opportunities to gain benefits. CNC machining most often involves doing the jobs of lathes, routers, mills and grinders, and it encompasses bending, forming, turning, Swiss-style machining and other processes as well.
CNC machining prompts many gains and few losses. The advantages of CNC machining apply to companies offering the service and to the clients who seek them. This tends to generate some benefits. A few of these benefits include:
There are a few disadvantages that may deter some businesses from choosing CNC machining:

You can rely on CNC machining for an endless number of applications within a full range of materials such as aluminum, carbon and stainless steel, titanium, brass, castings, plastic, wood, gold, silver and synthetic materials including ABS, polycarbonate and others. The call might be for tons of tiny metal plates bent to a certain angle and engraved with a number, or for a large panel punched to order.
A business might need fittings, spacers, bushings, shafts, manifolds, dies, fixtures, molds and any number of other parts. A huge benefit of CNC machining is how it not only performs in all kinds of environments, it enhances the business&#;s overall bottom line by doing the job faster and more cleanly than any other method.
Many essential metal fabrication tasks are made easier and faster with CNC machining:
The full range of capabilities CNC machining delivers makes it possible to create just about anything part or tool a business needs.
All kinds of businesses need precisely machined parts with unfailing consistency. Countless industries use CNC machining for their metal fabrication needs, including:
Aerospace: Every industry needs precision, but it&#;s especially important aircraft travel parts, such as an aircraft turbine engine, for example. Without precise parts, air travel for humans and goods could not be reliable and safe. Aerospace favors CNC machining because it offers the five-axis CNC machining needed, which can manage such hard-to-cut materials as Inconel.
Agriculture: From manufacturers of agriculture machines to large-scale farms and horticulture operations, CNC covers the needs of the agriculture industry. The operations demand high production and reliability, whether it&#;s hardware on gates to secure the livestock, parts on a harvester or electronic components.
Automotive: Think of all the shafts, gears, pins, brackets and other parts that are used on vehicles of all sizes and styles. From specialized auto to military vehicles, CNC machining answers a call for the large and small parts that keep the production lines moving.

Construction: The tools and equipment used to construct things, as well as the materials used to build them, inherently involve CNC machining. It&#;s a part of most building processes by nature of the wood, stone, nails, screws and other items used to create a structure. It might also be the answer to a desired architectural style, such as relief statues, or it could be needed for safety compliance or aid, such as with textured handrails.
Dental: Dental implants need machining to be just exactly the right shape. Besides the items that are surgically implanted, there are also the tools the doctors and assistants use. CNC machining puts just the right point, angle or bend on the business end of the instruments, as well as the texture on the handle that helps the professionals keep their grip.
Electronics: The brains inside most computers, the motherboards, have millions of tiny parts that must work with consistency and reliability every time. The intricate hardware of electronic items has rows of metal slats, panels, tiny wires, engraved numbers and other details that CNC machining serves well.
Electrical: An electrician&#;s crew comes across dozens of things in a day that involve CNC machining, from cut coils and breaker panels to light fixtures and decorative items.
Food and Beverage: Each time we push the bar at a convenience-store soda fountain or eat in a restaurant, there was or is CNC machining involved in serving our needs. It&#;s more than likely that every place that makes or serves food and beverages is intimately familiar with the technique and its capabilities.
Equipment: Light and heavy, big and small, all equipment alike involves CNC machining in one form or another. CNC machining might not be solely responsible for the creation of a huge earthmover, but it certainly it would be involved in many stages of its creation. The texture and size of fasteners, the shape of a crowbar, the gentle angles of a garden spade and its blade are all examples of tools and equipment CNC machining helps create.
Firearms: Weapons of all kinds may require CNC machining, but especially firearms. If you&#;ve ever seen a disassembled gun, you&#;ve seen the result of the CNC machining processes that created the pins, etched parts, barrels, plates, triggers, ammunition clips and other components of the firearm.
Jewelry: Imagine an engagement or wedding ring in its raw state as a chunk of silver or piece of titanium or gold. Professionals use CNC machining on multiple axes to cut a ring from those pieces. Another kind of CNC machining would be used to engrave the metal with &#;14-carat-gold&#; or another identifier. Jewelers also use small-scale CNC machining to make the personal inscriptions seen in and on jewelry.
Military: Broad needs for CNC machining exist within the military, where nameplates and defense implements might be on the same purchase order. The precision and uniformity produced by CNC machining fits so many aspects of the military&#;s nature, from its mighty instruments of war to its rows of identical buttons.
Printing: Commercial and newspaper printing plants use CNC-machined parts throughout their facility. The Newspaper printing presses and the ad-insert machines that work every day to produce the periodicals people expect to see were all partially created by CNC machining.
Manufacturing: Anywhere people are making something on a production or assembly line, there is probably CNC machining involved at several or all points. Levers, plates and panels are just a few of the big and small parts that keep production facilities running smoothly.
Transportation: Nearly all modes of ground transport use CNC machining, including rail, over-the-road trucking, transit and others. From the large sheets that make up the bodies of vehicles to the tiny circuitry and other electronics involved in transportation, it takes an array of CNC machining to keep all these vehicles running.
CNC machining often creates a tool or element essential to the business&#; product or function. For examples, spray nozzles and valves, panels, plates and fasteners are universal to a majority of companies, yet they are potentially used uniquely within each one. CNC machining frequently, if not always, offers smart solutions.
More applications of CNC machining work include multi-axis machining, where objects that would normally need to be cast are created from a solid piece of metal or other material. CNC processes routinely incorporate plasma and laser cutter technology, too.
Computer-aided design software produces a three-dimensional model of the final component, and the model can then be loaded into the system to program the machining and produce exact replicas. Once a template has been fed into the system, those same, exact replicas can be produced quickly and easily again and again.
Some mourn the loss of manual lathing and milling techniques, but these techniques are bound to persevere and even flourish outside the high-production environment. The growth of CNC machining, in fact, has led to the growth of new industries as well as educational courses geared toward CNC programmers and operators.
The field of programming or operating CNC machines has been a growing career path for as long as the craft has been around, but even more so with the dawn of the data age. It pays a decent wage, and good programmers and operators are always in high demand.
It&#;s worth knowing how product quality is dependent on proficient CNC programming and operation. As you can imagine, if either one is off even a micro-fraction, it can cause problems. CNC machining providers should be scrutinized the same way any other commercial service vendor is, since the result of your product will be directly affected by the quality of a provider&#;s operators, programmers and equipment.
