Product Parameter (Specification)

Product Features

Our factory boasts a 4m x 10m CNC large lathe, capable of performing turning, grooving, and threading processes on ultra-large workpieces on a single machine. It's also equipped with an intelligent compensation system that automatically corrects errors caused by thermal deformation during machining, ensuring exceptionally precise dimensional and positional tolerances for ultra-large workpieces. Furthermore, it supports multi-axis linkage, enabling customized machining of complex contours, fully meeting the special structural needs of metallurgical and energy equipment.

Product Applications

Our Large Machine Tool Processing Parts have a wide range of applications, including core components such as large rollers on metallurgical rolling mills, turbine rotors in the power generation industry, and hydraulic cylinders in construction machinery. They can also be adapted to production line upgrades and component replacement needs of heavy equipment companies in Tangshan and surrounding areas, helping these heavy equipment operate efficiently and stably.

Yuexin Machinery's Large Machine Tool Processing Parts follow a comprehensive process control system: "Raw Material Screening - CNC Machining - Performance Testing - Finished Product Traceability". In the raw material stage, spectral analysis and magnetic particle testing are performed on steels such as 40Cr and 45# to strictly ensure that the raw material performance meets standards. In the machining stage, roughing, semi-finishing, and finishing are completed using a 4m×10m CNC large lathe. CNC grinding machines are used for further refinement of critical parts, precisely controlling dimensional tolerances within 0.015mm.

In the inspection stage, laser interferometers and hardness testers are used for comprehensive testing to ensure that the precision, hardness, and mechanical properties of large workpieces meet standards. Regarding process optimization, heat treatments such as tempering and nitriding are performed according to actual needs to effectively improve the fatigue resistance and wear resistance of large components. A rigorous process ensures the quality of the machined parts throughout the entire process.
