7 Top Benefits of CNC Machining

CNC machining, or computer numerical control machining, is a manufacturing process that utilizes computer-aided machines to cut metal or other materials into intricate patterns and shapes. It offers many unique benefits that make it a valuable technology for a wide range of industries.

Among the outstanding CNC machining benefits for machinists is that it allows them to re-shape and redesign existing parts without having to start from scratch. When they do create a part from scratch, they do so through CAD (computer-aided design) software which enables them to make very intricate designs with minimal wasted material. This method of machining can reduce waste and save money thanks to the computer’s capabilities and automation, instead of relying on human operators. Additional valuable differences make themselves plain depending on the application. In this article, we'll look at some of the top CNC machining benefits.

1. CNC Machining Generates Minimal to No Waste

CNC machining is not only efficient, but it can also minimize material wastage thanks to its precision and accuracy. As long as the part is designed properly in the computer, the machine itself will almost never make faulty cuts, so there will be fewer damaged parts to discard. The machine can handle precise cuts and angles without generating much waste. 

2. CNC Machining Is More Accurate and Has No Defects

One of the major CNC machining benefits is accuracy. Because CNC machines receive precise instructions from a computer — and the movements are similarly carried out under computer control — their results will be identical each time and will match the computer model closely. This is a huge advantage when it comes to creating parts with tight tolerances. This capability almost entirely eliminates human error from the equation. 

3. CNC Machining Offers More Rapid and Effective Production

Another industry-cornering CNC machining benefit is the inherent speed and efficiency of production. CNC machines are capable of producing products much more quickly and efficiently than traditional methods. Many modern units can even load the billet and unload the completed product without human intervention. Naturally, this capability leads to significant cost savings and increased productivity. In addition, this sort of automation makes parts more consistent. 

4. CNC Machining Makes Assembly Faster

Products whose components are created under computer numerical control are simpler to assemble. Because CNC machining is so precise and consistent, companion parts will fit together exactly as they do on the computer. And since the process is quicker than manual machining, you’ll spend less time waiting for parts to be completed. Unless there is a problem in the computer model, all parts should fit together perfectly. This capability can save a lot of time and money in the assembly process, as there is no need for extensive fitting and adjustment.

5. CNC Machining Separates Machines From People And Reduces the Risk That Would Otherwise Arise

CNC machining removes significant safety risks from the shop floor. By automating the machining process, you can eliminate many of the hazards associated with manual machining. In addition, CNC machines are typically enclosed, which further reduces the risk of injury.

6. CNC Machining Uses Little Energy

CNC machining uses less electricity than older processes, thereby reducing energy consumption. In fact, according to the EPA, CNC machining uses about one-seventh of the energy of traditional machining methods. There are multiple reasons; CNC machines not only work quickly but draw less power per minute than most other manufacturing methods. 

7. CNC Machining Reduces Production Costs

CNC machining is an economical, efficient, and precise process of manufacturing parts and products. CNC machining also uses fewer raw materials in comparison to conventional machining. Focusing your shop around CNC technology will drastically reduce errors, production expenditures, and product costs.

What is CNC Machining?

CNC machining is a subtractive manufacturing process used to create parts by removing material from a workpiece or workpiece stock. Preprogrammed software and codes are fed into the machine to control the movement of its equipment. CNC machining covers a wide range of machinery such as: turning mills, lathes, grinders, and plasma-cutting machines. For more information, see our guide on All About CNC Machining.

Benefits of CNC Machining Service vs Manual Machining

CNC (Computer Numerically Controlled) machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. Using this type of machine versus manual machining can result in improved accuracy, increased production speeds, enhanced safety, increased efficiency, and most of all cost savings.

What are the Benefits of CNC Machining?

  •  The accuracy of the CNC machine ensures consistent product quality. The process is more precise than manual machining and can be repeated in the same manner over and over again.
  • Increased production speed and increased efficiency. Computers are used to control the machines, the process is automated therefore increasing speed and quality of manufacturing. Considering machines do not tire or need breaks it makes it more efficient than manual machining.
  • One of the main advantages for the operators of CNC machines is safety. Using CNC machines are much safer than manually operated machines as they work behind a guard or even a closed, transparent safety door.
  • CNC machining is more cost-effective. Traditional machining requires one operator per machine. This type of machining requires fewer machine operators since one skilled operator can run several machines at one time. Since the CNC is so accurate it reduces errors from the manufacturing process and eliminates unnecessary waste.
