Recently, a 10-meter-long main shaft is being precisely machined on a horizontal lathe in Sanland’s production workshop. As a critical core component for heavy-duty mining equipment, this shaft requires extremely high standards in machining accuracy, coaxiality, and surface quality, fully demonstrating the company’s capabilities in large-scale component manufacturing.

Due to its substantial length and weight, the machining process places high demands on equipment stability and operational expertise. Prior to processing, the technical team conducted detailed process analysis and developed a comprehensive clamping and machining plan to ensure strict control over dimensional accuracy and surface roughness at every stage. The horizontal lathe was thoroughly inspected and calibrated to maintain stable performance during long-duration continuous machining.

Throughout the process, operators strictly followed technical specifications and continuously monitored machining parameters and dimensional variations to ensure that all critical tolerances met design requirements. Meanwhile, quality inspection personnel carried out in-process measurements and staged re-inspections of key dimensions to guarantee full quality control and traceability.

The successful machining of this large-scale shaft not only reflects Sanland’s strong capability in heavy-duty component processing, but also lays a solid foundation for subsequent equipment assembly and stable machine operation. Moving forward, the company will continue to enhance its manufacturing capacity for large structural parts and key components, delivering high-standard solutions to customers in the mining industry.

Sanland remains committed to quality excellence and continuous improvement, steadily advancing in the field of heavy mining equipment manufacturing.
