Regardless of the industry, quality is a key factor because everyone likes to buy good quality items. Sometimes quality is even the foundation of a business. So as a qualified CNC machining supplier, how should we control the quality? There are some tips to help you improve your quality control.

1 Double check the order and understand the product design

After receiving the customer's order confirmation, we need to check the details of this order carefully, such as material, quantity, post-processing...Sometimes the order is different from the initial quotation you provided, so we need to check all the details carefully.

When receiving the CAD drawings of the customer's final product, our engineers and technicians will carefully analyze the design of the product, understand the specifications and requirements of the product, and then propose the most cost-effective parts processing plan to save costs. Processing costs, to achieve the maximum benefit of processed products.

2 Check the detailed requirements of the drawings

Usually some detailed requirements, such as holes, threads, tolerances, chamfers... will be marked on the 2D drawing. We need to check this information carefully before production to avoid secondary manufacturing. This saves cost and time and maintains tolerance requirements.

3 Incoming material inspection

Only good materials can make high-quality products, so incoming inspection is very necessary and important. Inspection can help us screen out inferior raw materials, while avoiding product processing risks, saving costs and time, and is an essential step before controlling product production.

4 Check the first

When the first product is ready, we will send it to the quality control department for dimensional and visual inspection. Only when all the indicators of the first product meet the requirements, will the production department be notified to continue production, which can ensure the quality of products of the same level and batch to the greatest extent.

5 Provide final inspection, test report and certification documents

After all the products are finished, we will do the final inspection and provide the customer with the inspection report or test report. Generally, products that are absolutely outside the inspection tolerance will be sent directly to the production department for re-production. Occasionally, a batch or part of a product will slightly exceed the tolerances required by the customer. We will send the test report to the customer and ask for their suggestion, the customer can better judge whether the product is in stock by comparing the test report.

The above are some tips on how to control quality in CNC machining, which are also very helpful in product processing. Any processing needs to be produced according to a certain process.
