Frequently Asked Questions About Stainless Steel Machining in China

What types of stainless steel are commonly machined in Chinese factories?

You’ll often find that Chinese factories work with various types of stainless steel, including austenitic (e.g., 304, 316), ferritic (e.g., 430), and martensitic (e.g., 410) steels. Each type has its own properties and applications, such as corrosion resistance, ductility, and hardness. For example, austenitic steels like 304 and 316 are widely used due to their high corrosion resistance and durability.

What CNC machining processes are used for stainless steel parts?

Chinese factories employ several CNC machining processes for stainless steel, including CNC milling, CNC turning, CNC drilling, and Swiss machining. CNC milling is great for creating complex shapes and precise tolerances, while CNC turning is ideal for producing cylindrical parts like screws, bolts, and shafts. Swiss machining is specialized for intricate parts from bar stock.

What equipment is typically used in stainless steel CNC machining?

The equipment used in stainless steel CNC machining includes milling machines, CNC lathes, and CNC machining centers. These machines can be 3-axis, 4-axis, or 5-axis models, allowing for high precision and versatility in producing parts of various sizes and complexities. World-class facilities often use brand-name machines like Brother, HAAS, and Mazak.

Machining stainless steel can be challenging due to its hardness and tendency to work harden quickly. This requires higher cutting speeds and feeds, as well as cutting tools with high wear resistance. Additionally, stainless steel can be gummy and sticky, so using plenty of lubricant and coolant is essential to maintain quality and prevent tool wear.

How do Chinese factories ensure the quality of stainless steel machined parts?

To ensure quality, Chinese factories implement rigorous quality control systems. This includes 100% inspection before delivery, using testing instruments like CMM, H.gauge, and microscopes. Many factories also hold ISO certifications and provide material certificates and SGS reports to guarantee the quality and compliance of the materials used. Experienced engineers and machinists play a crucial role in maintaining high standards of precision and accuracy.
