3.If any precision machined steel component fails to meet tolerance requirements or your custom specifications for steel parts, we will remake and deliver it as quickly as possible—free of charge.
4.Over the years, JINGXIN has manufactured thousands of precision custom CNC machined steel components for customers, earning a 99.9% satisfaction rate. This track record drives us to keep refining our services, ensuring we consistently deliver high-quality precision steel components that meet your exact custom needs.

Our precision commitment to our Custom CNC Machining Services:​

Our customized CNC processing offers critical dimensions of steel components with an accuracy of ±0.005mm, strictly adhering to the ISO 2768-F/M standard - for the demanding requirements of heavy industrial equipment, we can also provide more stringent, application-specific tolerances (such as ISO 2768-ES). We use advanced measurement tools like coordinate measuring machines and optical inspection instruments to verify every key detail, from surface roughness to geometric tolerances, to ensure that these steel components maintain stable dimensional accuracy under extreme working pressures such as heavy loads, continuous operation, and harsh industrial environments.

This level of precision is of utmost importance: it ensures the structural integrity of the load-bearing components, enables seamless assembly with other heavy-duty system components, and guarantees consistency in performance across all batches, whether for custom prototypes or large-scale mass production. Our customized CNC processing services are specifically designed to meet the unique specifications of your heavy industrial equipment. Our precision can directly translate into reliability and durability.
