About JINGZUAN
JINGZUAN Industrial Machinery is a professional manufacturer specializing in precision machining, deep hole drilling, boring, honing, long-shaft turning, and large-scale CNC machining. Based in Taicang, Jiangsu, China, we provide customized machining solutions for customers requiring high-precision manufacturing of complex, extra-long, heavy-duty, and difficult-to-machine components.
With a 4,000 m² manufacturing facility, machining capabilities of up to 10 meters in length, and a maximum workpiece handling capacity of 25 tons, JINGZUAN is equipped to take on demanding machining projects involving deep holes, large dimensions, complex structures, and tight tolerances. Our capabilities include deep hole drilling from Ø2-150 mm, boring and honing of components up to Ø1,500 mm in diameter, and precision machining with tolerances controlled down to 0.02-0.04 mm, depending on the application and component requirements.
In addition to conventional metal materials, we have extensive experience in machining difficult-to-machine materials, including nickel alloys, titanium alloys, and high-temperature alloys. These materials place demanding requirements on equipment, cutting tools, machining parameters, process stability, and dimensional control. Through optimized machining processes and accumulated technical experience, we are able to provide reliable solutions for components that present challenges in machinability, precision, and production efficiency.
Our machining services support a wide range of industries, including aerospace, nuclear power, energy, petrochemical processing, metallurgy, shipbuilding, hydropower, chemical equipment, mining machinery, and other heavy industrial applications.
From technical drawing review and manufacturing process planning to precision machining, dimensional inspection, quality control, and documentation, we provide comprehensive support throughout the entire manufacturing process. Every project is evaluated according to its material characteristics, structural complexity, dimensional requirements, and application conditions to develop an appropriate and reliable machining solution.
Supported by an ISO 9001:2015 quality management system, advanced machining equipment, and an experienced technical team, JINGZUAN is committed to delivering consistent quality, reliable manufacturing capabilities, and customized solutions for demanding industrial components.
Whether your project involves deep holes, complex geometries, extra-long parts, heavy workpieces, tight tolerances, or challenging materials, JINGZUAN is ready to support your requirements with professional engineering expertise and precision manufacturing capabilities.
Send us your drawings, material specifications, quantities, and technical requirements. Our engineering team will evaluate your project and provide a customized machining solution tailored to your needs.
