The Major Benefits of CNC Machining in Manufacturing

Across the world, manufacturing demand continues to increase, and supply continues to run short. CNC milling and other CNC machining processes play a critical role in adapting to this tension. CNC machining, otherwise known as computer numerically controlled machining, is an automated machining process that requires an operator to input code into a computer program that then operates the machine.

CNC machining produces items that we use in our day-to-day living. For example, precision manufacturing is necessary for kitchen appliances, car parts, medical tools, and more. Think about your phones or computers. CNC milling helped produce components of devices all throughout your home. Technology continues to drive the manufacturing industry forward, leading to an even higher demand for CNC machining.

CNC has always provided major benefits when it comes to manufacturing, and these benefits will only increase over time. Let’s take a look at some of the most significant benefits of automated CNC milling machines when it comes to milling metals or plastics.

Lower Risk

Because CNC milling equipment runs as a result of a computer program, fewer humans are required on the machining floor. These factories are nothing like the factories of old that were dusty and had humans operating large, heavy, dangerous machines. Operators don’t have to crouch or end like in the past; today, operators run the CNC machines from a computer. Additionally, a CNC milling machine operator works in a separate enclosed space, where they can see the machine and worktable at work.

Less human interaction results in a lower risk of injury or error. Subsequently, CNC machines are significantly safer for workers and often have fewer supervisory requirements. In the past, milling machines could lead to significant injury, especially in early factories. Because of the possibility to automate and have less human interaction, CNC milling is also ideal for materials that might be more toxic.

Greater Efficiency
Because CNC machines are run by computers, all of the major operations required for producing a part can be automated. This automation has several effects, and one of them is greater efficiency. CNC machines can run 24/7 until they require maintenance (and significant downtime). Even that has the potential to improve—as AI, IoT sensors, and more are further integrated with the machines, sensors can support predictive maintenance, which requires less downtime. Increased efficiency with CNC milling machines leads to higher production rates.

Consistent Quality-Controlled Results

Accuracy and consistency are critical when parts contribute to products that have the potential to save or destroy lives. From the aerospace industry to the automotive industry, companies rely on CNC milling and turning to ensure that their high-stakes parts are accurate and within an incredibly precise measurement, +/- fractions of a millimeter. Because CNC machines follow coded programs, they can create the same part over and over with little to no difference in quality. Although this repeatability has been important to manufacturing for a long time, no alternatives have managed to meet CNC milling’s capability.

Lower Cost

Taken as a whole, all of the above factors result in a lower overall cost for CNC milling machines, like other CNC machines. Because CNC machining operates at a higher speed and involves fewer humans, production costs are significantly lower than they have been in the past. Additionally, CNC machines often offer versatility, as there are numerous CNC milling attachments available.

CNC milling services, like other CNC machining processes, offer these major benefits. Whether you need CNC turning services, CNC milling services, or CNC lathing, you can guarantee that your parts will be lower risk, lower cost, and consistently well-made to an exacting standard.
