Guidelines for CNC Machining Quality Control
No matter which industry, quality is a key factor, because everyone likes to buy high-quality goods. Sometimes, quality is even the foundation of an enterprise. As a qualified CNC processing supplier, we should do as follows:
No matter which industry, quality is a key factor, because everyone likes to buy high-quality goods. Sometimes, quality is even the foundation of an enterprise. As a qualified CNC processing supplier, how should we control the quality? There are some tips that can help you improve quality control.
1 Check the order carefully and understand the product design
After receiving the order confirmation from the customer, we need to carefully check the details of this order, such as materials, quantity, post-processing... Sometimes the order is different from the initial quotation you provided, so we need to carefully check all the details
When receiving the CAD drawings of the customer's final products, our engineers and technicians will carefully analyze the product design, understand the product specifications and requirements, and propose the most cost-effective part processing scheme to save costs. Processing cost, to achieve the maximum benefit of processing products.
2 Detailed requirements for drawing review
Usually, some detailed requirements, such as holes, threads, tolerances, chamfers... will be marked on the two-dimensional drawings. We need to carefully check these information before production to avoid secondary manufacturing. This saves cost and time and maintains tolerance requirements.
3 Incoming inspection
Good materials can make high-quality products, so incoming inspection is very necessary and important. Inspection can help us screen out inferior raw materials, avoid product processing risks, save costs and time, and is an essential step before controlling product production.
4 Check the first piece
When the first product is ready through CNC processing, we will send it to the quality control department for dimensional and visual inspection. The production department will be notified to continue production only when all indicators of the first product meet the requirements. In this way, the quality of products of the same grade and batch can be guaranteed to the greatest extent.
5 Provide final inspection, test report and certification documents
After the completion of all products, we will conduct final inspection and provide inspection reports or test reports to customers. Generally speaking, products that absolutely exceed the inspection tolerance range will be directly sent to the production department for re production. Sometimes, a batch or part of products will slightly exceed the tolerance required by customers. We will send the test report to the customer and ask for their suggestions. The customer can better judge whether the product is available by comparing the test report.
The above are some skills on how to control quality in CNC processing, which are also helpful in product processing. Any processing needs to follow a certain process. If you are looking for high-quality prototype and customized mechanical parts suppliers, please feel free to contact us.
