In recent years, although CNC machining methods have become mainstream, it has become a difficult problem for manufacturers to choose high-quality machining manufacturers. So how to solve this problem? Today, the editor of HKAA will teach you how to find a reliable mechanical parts processing factory.

To find a high-quality processing factory, you can examine the following aspects;

1. Standardized operating procedures

Operating procedures are the basis for ensuring product quality. When choosing a mechanical processing factory, you must have a certain understanding of the operating procedures of the machinery factory.

Learn more about it in more detail, such as: whether the safety startup inspection before startup, startup reset, and startup preheating are completed as required; the program sheet mold number, workpiece number, reference angle orientation, XYZ three-axis number acquisition method and number acquisition surface Determine whether it is reasonable; clean and arrange the clamping before loading the workpiece on the machine, tighten the screws, and check the workpiece calibration; recheck the tool and safety inspection and processing data inspection when starting processing; clean the workpiece before dismounting the machine and other related processing operations Whether the process is standardized and whether there are clear regulations.



2. Implementation of conventional processing standards

As for processing standards, any enterprise engaged in mechanical processing should pay attention to them. Processing standards are the guarantee of accuracy after products are made. Only by meeting the standards can qualified products be manufactured.

Conventional processing standards include: whether the processing requirements for the structural assembly groove on the mold core are the same as those for the mold base; whether the processing and discharge drawings are based on the engineering parts drawing; whether the parting surface polishing knife margin is not exceeded for small molds 0.05mm/S, while large molds cannot exceed the standard of 0.08mm/S, etc.

3. Quality of workpiece delivery

The delivery quality of workpieces is the most intuitive way to reflect the strength of a mechanical processing factory. When considering the quality of workpiece delivery, you can get to know the companies that have cooperated with the machining shop before. Ask them whether the surface quality and size of the workpiece they received are the same as the drawings, etc.



Identifying quality CNC machining manufacturers is crucial to ensuring that your parts or products are manufactured with precision and reliability. Here are some key factors to consider when evaluating CNC machining manufacturers:

1) Experience and Reputation:

Look for manufacturers with a solid track record and extensive experience in CNC machining. A company that has been in business for a longer period is likely to have refined its processes and gained valuable expertise.Find out whether the factory has experience working with similar companies and whether it can meet your specific needs.

2) Certifications:

Check if the CNC machining manufacturer holds relevant certifications.Understand whether the factory has a strict quality control system, which can reflect the importance the factory attaches to product quality. ISO 9001 is a widely recognized standard for quality management systems. Other industry-specific certifications may also be relevant, depending on your requirements.

3) Facility and Equipment:

Check whether the factory is equipped with advanced processing equipment and technology, which will directly affect the processing accuracy and quality of the product.Visit the manufacturer's facility if possible or inquire about their equipment. High-quality CNC machining requires state-of-the-art equipment and a well-maintained facility.

4) Technical Capabilities:

Understand whether the factory's technical team has rich experience and professional knowledge, and whether it can provide technical support and solutions.Assess the manufacturer's technical capabilities, Ensure they have the expertise to handle the specific materials and tolerances required for your project. Look for a diverse range of machining capabilities, including milling, turning, and precision grinding.

5) Quality Control Processes:

Inquire about the quality control processes in place. A reputable CNC machining manufacturer should have robust quality control measures at every stage of the manufacturing process. This includes inspection and testing of raw materials, in-process inspections, and final product quality checks.

6) Material Selection and Sourcing:

Verify that the manufacturer has experience working with the materials required for your project. Ask about their material sourcing practices to ensure they use high-quality materials from reputable suppliers.

7) Communication and Collaboration:

Evaluate the manufacturer's communication and collaboration processes. A good manufacturer should be responsive to your inquiries, provide regular updates on the project's progress, and be open to collaboration on design improvements and modifications.

8) Customer reputation:

Look for customer reviews and feedback about the factory to understand its reputation and credibility in the market.

9) Cost and Quoting Process:

While cost is an important factor, it should not be the sole determinant. Consider the overall value offered by the manufacturer, taking into account factors such as quality, lead times, and communication. Be cautious of significantly lower prices that may indicate compromises in quality.

10) Flexibility and Scalability:

Assess the manufacturer's flexibility and scalability. A good CNC machining partner should be able to adapt to changes in project requirements and accommodate varying production volumes.

11) Reliable and stable customization capabilities:

Find out if the factory can customize processing to your specific needs to meet your business needs. Whether the factory operates stably and can provide you with long-term services.

12) Visit the factory:

If possible, you can conduct an on-site inspection to observe the factory's operations, employee work attitudes, and on-site equipment status, etc., in order to more accurately evaluate the factory's strengths and weaknesses.

Consider establishing a long-term relationship with the factory to obtain better service and preferential treatment.By thoroughly evaluating these factors, you can identify a CNC machining manufacturer that meets your quality standards and can deliver reliable and precise parts for your specific needs.
