How is the CNC Machining Process Done


If you are in search of an ultimate guide to CNC machining that combines information with persuasion, then you are in the right place. Our professional CNC machining manufacturer team has put together a comprehensive and personalized article that provides insights into the CNC machining process, its benefits and applications.

The Basics of CNC Machining

First off, let’s define CNC machining. The term refers to computer numerical control. It is a computer technology that automates manufacturing control. The CNC machining process involves programming a computer to control a device that cuts and shapes the material. The result is a highly accurate and precise finished product.

One of the benefits of the CNC machining process is its ability to produce large quantities of products with consistent precision. Additionally, it offers greater flexibility and cost-effectiveness compared to other forms of manufacturing.

CNC Machining Process Explained

CNC machining is an automated process that uses computer-controlled machine tools to produce precise parts from a variety of materials, including metal, plastic, wood, and more. The process involves a series of steps that are repeated to create a final product. The steps in the CNC machining process include:

Designing the Part – This is the first step in the process, where the customer sends to us a CAD drawing of the part he needs. At this stage, we review the drawing to ensure that it is manufacturable and can be produced according to the customer’s specifications.

Programming – Once we have reviewed and approved the design, we use specialized software to create a CNC program that will control the machines used to make the part. This program tells the machines where to cut, how deep to cut, and at what speed to work at and positioning every axis on the machine.

Material Preparation – After programming is complete, we prepare the material for machining. This involves selecting the right type of raw material, mounting it securely in the machine, and ensuring that the tools are working effectively.

Machining of the Parts – The next step involves cutting the part from the material using the computer-controlled machines. Here, we use precision CNC turning machining techniques to create parts with tight tolerances, high accuracy, and smooth surface finishes. Furthermore, we have multiaxis machines that can machine complex parts, and without breaking. For instance, our lathes have excellent accuracy in turning, boring, and threading, which results in identifying slight defects that other machine tools may have missed.

Quality Inspection – After the machining is done, the part is closely inspected to ensure it meets the customer’s requirements. We utilize some advanced checking processes and tools such as CMMs and optical comparators, which measure surface roughness and carry out other quality tests.

Finishing and Packaging –Lastly, the finished part is given a final finishes such as powder coating, electroplating, or anodization in preparation for assembly or shipping to the customer.

How Precision CNC Turning Machining Impacts the Quality of Parts Produced

As we have mentioned before, precision CNC turning machining plays a vital role in the quality of parts produced in the CNC machining process. By combining advanced computer programs, multi-axis machines, and high-precision turning tools, we can produce parts with precise dimensions within a thousandth of an inch. This ensures that the part will fit correctly and function as intended.

Moreover, our quality control processes also play a crucial role in ensuring the accuracy and reliability of the parts produced. By using the latest measuring tools and techniques, we can identify and correct any issues that may arise during production, such as tool wear or machine vibration.
