In CNC manufacturing, a fraction of an inch can make a difference between a successful product and a lost customer. There are several ways to promote quality control (QC) in CNC production. This article will explore some of them form several perspectives.

What is CNC machining quality control?

Quality assurance is the process used by CNC processing companies to help measure the quality of CNC equipment. The main goal of implementing quality control in the manufacturing process is to ensure that the products produced meet the company, industry and consumer expectations. A quality control system monitors all components, including the parts being produced and the employees who assemble the parts. By receiving high quality products, not only do customers benefit from quality control, but also because manufacturers reduce costs and increase efficiency. To effectively implement a quality control plan, you must be cautious. Imperfect implementation can be costly for the company. Effective implementation begins by defining quality standards for each product. Then define the number of products to test before conducting employee training. Finally, there should be a communication system to report defects or potential problems in CNC manufacturing.


How to achieve quality control in CNC machining?

  • Project engineers and quality engineers must clearly understand and understand the customer's drawings and requirements, and must check each detail tolerance and standard. This is the best part function and purpose to work with the customer, so we can let our machining engineers how to machine parts, how to control key points, and how to ensure high requirements.

  • The tolerance must be in the microscopic range. If the tubing valve used is 1mm smaller than the specified one, the result may be tens of thousands of new cars leaking oil. Similar unnecessary and unexpected results can occur in aerospace, shipbuilding, home appliances and other industries. Avoiding these errors is the key to quality control.

  • One of the most important things manufacturers do to maintain high quality is to calibrate frequently and follow maintenance agreements. The machine may lose calibration due to vibration, vibration, and other accidents on the factory floor. Many maintenance protocols do not include spindles on CNC equipment. Using them as an integral part of your maintenance plan can deliver significant returns by reducing downtime.

  • Use your own quality control staff to check or have the tester go to your facility for inspection.

  • Become and maintain ISO certification. For example, ISO 9000 certification. Companies with ISO 9000 certification improve their business operations by implementing better business processes, reducing scrap, reducing product rework and reducing costs. In addition, ISO certification is an important tool for sales and marketing personnel. In addition, some ISO certified manufacturers require their suppliers to also have certification.

  • There is a skill gap between factory workers, including CNC operators. One way manufacturers can address this skill gap is to build partnerships with local colleges and universities and provide apprenticeship training for future CNC operators.

  • For some very special quality requirements, we can turn to the quality laboratory. As we all know, the factory can not buy all the measuring machines, which will be a huge investment. However, sometimes, when the product is out of specification, it is not possible to determine where the problem occurred during the operation. Then we can take the product to the quality lab for testing.

  • Record keeping is another strategy to improve quality. Recording inspection results and displaying them in charts or tables provides an easy way for quality control personnel to view data from any CNC machine in the factory floor and monitor them for common and anomalous problems.

  • Risk can be minimized. There are many other financial risks that should be considered not only in the factory, but also after the product is shipped from the factory. Product recalls can be a very expensive job, and they can have a negative impact on customers, hurting your brand name indefinitely. An effective quality control system includes a robust inspection at different stages of the manufacturing process to help determine that all manufactured products meet minimum requirements before reaching the consumer.

  • Resource protection is very important to manufacturers because it reduces the total upfront material costs. As assembly pollution is reduced, manufacturers can achieve higher throughput and higher returns.

  • Every industry has a set of regulations that must be met, including manufacturing CNC machining. Failure to comply with standards can be an expensive thing. It can also cause production bottlenecks. Ensuring that bottlenecks in the manufacturing process do not cause economic losses.

  • If you can't consistently produce high quality products, it will seriously affect your company. Consistency not only affects your company's reputation, it also affects production costs. If manufacturing doesn't maintain consistency, you're bound to experience fluctuations in production costs. Quality control plays a huge role in ensuring that the quality of the products you produce is consistent.


As mentioned above, quality control is an integral part of the manufacturing process. It not only ensures that the company produces high quality products, but also ensures that it complies with the standards set by the regulatory body. Everyone is involved in quality control when the manufacturer has a high quality process. Producing high quality products is an effort to start from the executive floor and become a reality at the factory site.
