Why Manufacturers Prefer CNC Machines

by Chirag

Several decades ago, machinists were the talk of time and were responsible for crafting everything to perfection. Similar skills are still required, but when talking about producing a given piece on a large scale and with higher precision, nothing beats computerized machines’ superiority. That’s where CNC Machining comes in.

Following the invention of personal computers, numerical systems have penetrated almost every industry. Nowadays, custom CNC machining is an essential part of modern machining technologies. Unlike traditional machining, CNC machining involves the operator working with the main software in motoring machine tools as well as creating programs. Therefore, it’s easily said that CNC machining is an immense upgrade. So, what are the advantages of CNC machining?

Worker Safety

Unlike traditional machining, CNC machining has ensured that the worker’s safety is at the highest level. The operator is well protected from sharp parts by protective gear. Thanks to the glass, the operator clearly sees everything going on. Moreover, the operator is not necessarily required to get closer to the mill or spindle, or even anywhere close to the cooling fluids that could be dangerous to the skin.

Precise Machining

It goes without saying that CNC Machining brings the highest level of precision. With the machine, it’s very easy to carve out a product from material exactly as required. Therefore, it’s effortless to create a plethora of components with complex shapes within a short period.

Stable Replication Accuracy

You can’t think of something more stable than a proven computer program. Once the design is introduced into the computer, the machine is capable of repeating the manufacturing process over and over again.

Given that the precision is from the step-motors, it means that the movement is always similar, meaning you’ll always get the highest level of precision.

Labor Economy

In a nutshell, CNC machining improves automation. They require little attention once set in motion. The tools move automatically, with the operator only required to check whether there are errors in the setup or the program.

Therefore, there’s a lot of free time for an operator to be used on different tasks. The company can even retain fewer operators, meaning a lot is saved.


In the past, things were done differently in that a milling machine had to do planes or groves, drilling machines make holes, and a lathe to do tapers and cylinders. However, with CNC machining, all those tasks can be combined in a single machine tool.

Given the ability to program a trajectory of a tool, one is able to replicate any movement on any given machine tool. Therefore, the industry can be able to keep up with consumer demand.

Range of Materials

Another benefit of CNC machining is the fact that they can be used in the manufacturing of products from a plethora of materials. They include steel, bronze, polymers, and aluminum.

Fewer Test Runs

CNC machining has its way of avoiding test runs. For instance, it employs a visualization system to enable the operator to see what may happen to stock once all tool passes are done.

Together with minimum setup errors, the advantages of CNC machining are too many that manufacturing industries have grasped and are working to their advantage.
