Product Feature And Application

Tangshan Yuexin Machinery Manufacturing Co., Ltd. is equipped with a complete set of large-scale equipment, including an 8.5m×4.6m CNC gantry machining center and a 5m heavy-duty vertical lathe. This enables integrated processing of ultra-large workpieces, significantly reducing clamping errors. Utilizing digital programming and online monitoring, dimensional accuracy and stress changes are monitored in real time during processing, with tolerances in key areas controlled within 0.01mm. Furthermore, large structural components undergo annealing and vibration aging treatments to completely eliminate internal stresses generated during welding and processing, preventing deformation during use. Custom processing of complex irregular structures, thick-walled deep holes, and ultra-large flanges is also supported, accurately replicating customer drawings to fully meet personalized assembly requirements.

Large mechanical processing components are widely used in metallurgy, mining, and wind power. In metallurgy, they can be adapted to core structural components such as rolling mill frames, continuous casting machine beams, and sintering machine bodies. In mining machinery, they can be used for heavy-duty components such as crusher frames, conveyor main beams, and hoist housings. In wind power, they can be matched with key parts such as nacelle bases, hub supports, and tower connection flanges. With their stable performance, they provide reliable support for the core support, transmission, and connection systems of heavy equipment, ensuring long-term stable operation even under heavy loads and harsh working conditions.

Yuexin Machinery's large mechanical processing components are subject to strict standardized management throughout the entire process: "drawing analysis - raw material selection - precision machining - heat treatment - full-item testing." Each step is rigorously controlled to guarantee product quality. In the pre-processing stage, a team of senior engineers analyzes customer drawings, optimizes machining and welding processes, and proactively avoids potential risks in processing oversized parts. In the raw material stage, steel undergoes spectral analysis, ultrasonic testing, and mechanical property testing to ensure the material is free of internal defects and meets composition standards. The machining stage utilizes CNC equipment to process parts in stages according to preset programs. Complex processes employ multi-axis linkage technology, while oversized parts utilize a "segmented machining + splicing calibration" model to ensure machining accuracy.

The post-processing stage thoroughly eliminates internal stress through annealing and vibration aging processes. Rust prevention treatments such as painting and galvanizing can also be performed as needed. The inspection stage uses a coordinate measuring machine, laser interferometer, and ultrasonic flaw detector to conduct comprehensive testing, simultaneously issuing detailed inspection reports to ensure that every vertical lathe-machined part meets customer standards and usage requirements.
