CNC product quality is maintained through three steps: pre-production, during production, and before delivery.
In pre-production, MQJM’s procurement department strictly adheres to standards when acquiring raw materials. The QC team inspects 25% of these materials, and only qualified ones are processed. During production, technicians adjust CNC milling equipment and produce test parts for evaluation. Production proceeds only when test data meets criteria. The QC team inspects CNC millng parts every half hour, halting production for any discrepancies. Before delivery, QC personnel inspect the product's appearance, check for drilled holes, threaded components, and verify the assembly process. This ensures customers receive the products of CNC milling parts identical to the drawings. CNC milling is a subtractive manufacturing process to produce a custom-designed part or product. Given the high precision and technical requirements of CNC milling services, implementing a robust QA process is essential for maintaining high standards of quality.
MQJM provides various CNC machining tolerances based on your design requirements. Depending on the shape and material of your parts, we can achieve minimum tolerances for thread sizes as small as 0.005mm. We adhere to national milling tolerance standards, with metals following ISO 2765-m and plastics following ISO 2768-c.

CNC milling is extensively used in the automotive industry to manufacture high-precision parts such as engine components, gearboxes, and custom fittings. It allows for the creation of complex shapes and designs, contributing to the efficiency and performance of vehicles.
The aerospace industry relies heavily on CNC milling for the production of intricate parts for aircraft and spacecraft. These parts often require high precision and adherence to strict standards, which CNC milling can deliver.
CNC milling plays a crucial role in the medical industry, being used to create surgical instruments, orthopedic implants, and medical devices. Its precision and consistency ensure the high quality and safety standards required in medical devices.
CNC milling is used for its precision, efficiency, and versatility in manufacturing. lt can produce complex shapes and high precision parts that would be difficult to achieve with manual machining. CNC milling machines can operate on a variety of materials, including metals, plastics, and wood, making them suitable for a wide range of industries. The process is also highly repeatable, ensuring consistent quality in high-volume production. Additionally, CNC milling reduces the risk of human error and increases safety by minimizing direct human interaction with the machinery. It's a cost-effective solution for both prototype development and large-scale production.
Large-scale milling and other CNC services enable the high-precision creation of very complex workpiece shapes. The method of computer-controlled digital devices is fully automated, making it possible to achieve effects that are difficult to achieve with manual control in a short period.
