How We Do Quality Control for CNC Machining Process and Products | CNCLATHING


No matter which industry, product quality is crucial. In order to meet the expectations of customers, trade standards, and industry regulation, implement quality control with different measuring instruments and tools to inspect the CNC machined parts produced in our machine shop.

Why Quality Control is Important?

Quality control is an overall inspection of products and manufacturing process, in CNC machining, the quality control is essential to ensure the products manufactured conform to the standard and requirements of the enterprise, industry and customers. In addition, proper quality control of CNC parts will avoid defective products, minimize risks, ensure the dimensional accuracy and quality, conserve the resource, reduce cost, and improve efficiency. It’s good for both manufacturers and customers. 


Therefore, an effective quality control system should be built starting from defining and establishing the quality standard of each part. The professional quality control and inspection employee is also necessary. 

How We Do Quality Control for CNC Machining Process and Products

CNCLATHING is focusing on CNC machining parts quality control for each project, confirm each client receives the desired product.

1. Learn about the industry background

Based on the different standards in various industries, when we received an order, other than focusing on design drawings, we also need to understand the industry background. For example, medical and military parts generally should be come in outstanding precision, absolute safety, excellent quality, and tight tolerance, maybe need to withstand extreme conditions. CNCLATHING is specialized in custom CNC machining parts in a wide range of important industries, like medical, food processing and packaging, electronics, automobile, aerospace, military, marine, machine tool, high-tech, and more.


2. Understand the design of the product

When customers sending a CAD drawing of the final product, our engineers and designers will analyze the design in detail and carefully, understand the product specifications and requirements of clients, check out each detail before production. We’ll use the most cost-effective solution to machine your part, control the factors throughout the CNC machining process, and ensure achieve the demands.


3. Check out parts with precise measuring device

Professional measuring machine operator at Junying will work with the final parts after machining. There are various advanced measuring tools now can be used for the measurement of lots of inspects, like dimensions, hardness, colors, tolerance, etc. Inspectors may do inspections on the part either it’s on the machine or after removing it from the machine. Go/no-go Gage, micrometers, CMM (Coordinate Measuring Machine), In-process probing and Air Gage are commonly used measuring equipment and tools.

4. Do inspection when the part is running

Sometimes, we need to implement quality inspection when the machined part is running, so as to identify problems early and rework the part before finishing. There are some operations that can be done to adjust the machine for holding tighter tolerance, such as adjust the tool offsets to leave a little excess stock, allow the tool to machine the workpiece, measure what the tool has done, and more. This is especially suitable for newly developed products.


5. Communicate with customers 

Whether in the manufacturing process, or after sending a sample, it’s effective to communicate with customer timely. Buyers and clients will have clear requirements on the product specification and function, when receiving an inquiry from customers, we will get in touch with them fast and give a free quotation as soon as possible, if there is something not get right, we’ll adjust the solution instantly. For special requirements, please tell us in advance.
