Development Capability
YuxingCorp Precision Machining Solutions Unit brings extensive experience in machining engine components such as engine blocks, connecting rods, cylinder heads, gear covers, and oil pans. With over a decade of expertise in developing diesel and gasoline engine blocks from prototype to mass production, we follow the APQP process throughout the development cycle. This ensures we deliver high-quality products efficiently and cost-effectively, consistently meeting our customers' needs and satisfaction.
Precision Machining of Main Bearing Side Faces
Achieving a geometric and dimensional tolerance of 0.015mm for main bearing side faces is highly challenging. However, through precise adjustments in our machining processes and the optimization of fixture PLC programming, Yuxing Corp has successfully met this demanding requirement.
Crankshaft and Camshaft Bore Machining
For crankshaft and camshaft bores, the required true position tolerance is 0.04mm, and parallelism is 0.02mm—challenging specifications. Although initial adjustments by external professionals fell short, Yuxing Corp's team conducted a thorough analysis and multiple process refinements, successfully meeting the stringent tolerances.
Simultaneous Machining of Side Frames
For side frames, we meet a true position tolerance of ±0.04mm for the finished bore, with a concentricity of 0.025mm, verified independently using CMM. For D175H6, D140H6, and D40H6, roundness is 0.03mm, and cylindricity is 0.004mm. Through extensive data collection and meticulous analysis, Yuxing Corp has perfected its machining control processes to consistently achieve these precise standards.
Quality Assurance Capability
With an advanced on-line quality management system in place, Yuxing Corp's Precision Machining Business Unit ensures comprehensive monitoring of the entire inspection process, from raw materials to finished products. By effectively implementing APQP and utilizing cutting-edge quality inspection techniques, we consistently deliver high-quality products and services to our customers. The unit is staffed with 5 Six Sigma Black Belt-certified employees, 20 Green Belt/Yellow Belt-certified employees, 10 quality engineers, 6 specialized inspectors, and 47 on-site quality control inspectors, all dedicated to maintaining excellence in every aspect of production.
