What Is CNC Machining?

CNC machining is a material reduction manufacturing process that creates parts by removing material from a workpiece or workpiece blank. Software and code that has been written are fed into the machine to control the movement of its parts. CNC machining can be performed on many different types of machines such as plasma cutters, mills, and lathes.

Milling was the first type of CNC machining used in the market. CNC milling machines can process metal, glass, plastic, and wood. These machines have a wide range of features and functions that allow them to create and cut out intricate shapes or design patterns, and even engrave lettering on items. In the 1970s and 1980s, CNC machines were very expensive. Today, they are much cheaper and increasingly popular with professionals and hobbyists alike.

Why Is CNC Machining Important?

CNC machining is very important in today’s business world. This is because it allows for the manufacture of accurate, repeatable, and affordable products. This method allows for the creation of products that would otherwise be impossible or too costly to manufacture.

For example, CNC machining is one of the best methods for ensuring that telecommunications equipment such as radiators, microwave tower components, and amplifier housings are manufactured correctly. This method allows complex mechanical parts to be created and manufactured accurately by taking into account technical specifications, part dimensions, and geometry.

How Do I Pick a Suitable CNC Machine?

There are many things you need to consider when selecting a CNC machine. Here are some of the issues to consider:

  • Project goals. Before you do anything, consider the goals of the project. If you are primarily processing wood, a CNC cutting machine may be the best choice. If you are going to cut metal, a CNC plasma cutter is the best tool for the job.
  • Cost. Consider the cost. In addition to the price of the machine, the cost includes labor and maintenance.
  • Machine weight. Consider the weight of the machine. If heavy, hard work needs to be done, cast iron construction is the best choice. If that’s not possible, lightweight tools can usually be substituted.
  • Power. Another important factor to consider is the power level of the equipment. This will change your cost analysis, and your building’s electrical system must be able to handle it.

What Jobs Are CNC Machining Best Suited for?

If these jobs are important to you, then CNC machining is the best choice:

  • Producing parts that are more accurate than traditional methods.
  • Producing parts that require greater accuracy.
  • Producing large quantities of parts quickly.
  • Produce complex designs.
  • Reduce the cost of volume manufacturing.

Advantages of CNC Machining

Little Waste

Thanks to its precision and accuracy, CNC machining is not only fast, but it also helps you reduce material waste. As long as the part is built correctly in the computer, the machine makes few mistakes. This means fewer broken parts to throw away. The machine can make precise cuts and adjust angles without waste.

CNC Machining is More Accurate

Accuracy is one of the biggest benefits of CNC machining. CNC machines get their exact orientation from the computer and the movements are controlled by the computer. This means that the cut results will be consistent and closely match the computer model. This is a big advantage when you need to make parts with very tight tolerances. This feature makes it virtually impossible for humans to make mistakes.

CNC Machining Makes Production Faster and Better

One of the biggest advantages of CNC machining is that it makes output faster and more efficient. Traditional manufacturing methods take much longer and are not as effective as CNC machines. Many of today’s machines can even load blanks and unload finished products unassisted. This capability can save a lot of money and increase productivity. This automation also leads to more consistent parts.

CNC Machining Speeds Up the Assembly Process

Products manufactured using computer numerical control (CNC) technology are easier to assemble. CNC machining is so precise and reliable that parts are assembled as if they were on a computer. Since the machining process is faster than manual machining, you will have less time to wait for the machining to be completed.

Unless something goes wrong with the computer model, all the parts fit together correctly. Because of this, assembly will be faster and less expensive since there is no need for extensive measurements and adjustments.

Reduced Risks that Can Occur

CNC machining separates the machines from the people and can eliminate many of the safety hazards on the shop floor. By automating the process, you can get rid of many of the risks associated with manual machining. In addition, CNC machines are usually enclosed, which makes them safer.

Low Energy Consumption

CNC machining uses less electricity compared to older machining methods, thus reducing energy consumption. According to the EPA, CNC machining uses only one-seventh the energy of traditional machining methods. Not only do CNC machines work faster, but they also use less electricity per minute than most other machining methods.

Reduced Manufacturing Costs

CNC machining is an affordable, fast, and accurate manufacturing process when it comes to making parts and products. Another difference between CNC machining and traditional machining is that CNC machining uses less raw materials. Focusing your shop on CNC technology will greatly reduce errors, labor costs, and product costs.

Benefits of CNC Machining to Industry


Computer numerical control is a common machining process that can be used to control a wide range of machines. These machines range from grinders and lathes to milling and cutting machines. They can manufacture many things such as molds and metal parts. Using CNC machining processes can make every part of the manufacturing process better. Many companies will benefit from it.


In the aerospace sector, parts need to ensure accuracy and repeatability. Therefore, manufacturing parts using CNC machining is an obvious choice. To ensure that very important aircraft components work properly and safely, they must be within tolerances of ±0.0001 inches.

Most aerospace components, favored for their high strength-to-weight ratio, are crafted from aluminum alloys. CNC machining excels in producing a variety of parts, from shims to bearing housings. Incorporating aluminum casting into this process seamlessly extends its capability to manufacture complex, essential aerospace components efficiently.

Commercial Products

When manufacturing commercial products, you need to be able to produce parts in large quantities while keeping prices low. Because CNC machining is so flexible, it is possible to create parts of all sizes and shapes from a large number of different materials.

When making new products, CAD prototyping, 3D graphics, and modeling allow you to make prototypes that can be seen and accepted to correct errors in design before going into production quickly. Modifications and variations to existing products are also easy and can be put into production quickly.

Technological Electronics

Miniaturization of electronic products is a growing trend in the industry. This means that parts need to remain small and lightweight while also becoming more robust. CNC machines are used in the electronics business to design and manufacture a variety of production parts.

CNC small-scale machining and micro-machining can handle the unique materials required. Very tight tolerances can be maintained on the tiniest of parts even during the production of large quantities of parts.

Medical Industry

Accuracy is very important when it comes to parts used in medical equipment and tools. Machines that use CNC machining technology are constantly checked and changed to ensure that they work correctly and consistently. These machines are commonly used in the manufacture of medical tools, orthopedic appliances, and surgical implants. With CNC machines, you can machine the specialized materials you need and get a finished product that doesn’t need to be reworked to achieve a knurled or mirror finish.

CNC machines can automatically generate the reports needed to track products and obtain FDA process approvals. Because it records and creates its paperwork. When manufacturing new products, the rapid prototyping capabilities of CNC machining can reduce the time it takes to bring a product to market during the iteration phase. This is because CNC machining allows for quick small production runs, which can then be easily converted to large production runs when needed.

Optical Industry

Working with CNC machining specialists can save time at all stages, from prototyping to production. This is especially helpful in the optical business, where many tests are performed during the product development phase. With CNC machining technology, design changes and testing are made easy. Once a product is in production, the short lead times and high-quality control of CNC machining are critical to ensuring a profitable business.

For example, glass eyeglass lenses are manufactured by CNC systems that control water jets. These water jets can be directed to create complex features such as precisely angled bevels, steps, and grooves that would be difficult to create with other manufacturing methods.
