The SX150-12YL automatic double disc grinding machine is precision equipment specifically designed for engine connecting rod machining. It performs critical double disc grinding tasks in the manufacturing process of connecting rods for both diesel and gasoline engines. This machine enables continuous processing from rough grinding to finish grinding. By simultaneously grinding both ends of the connecting rod, it ensures uniform surface quality and precise dimensional accuracy, laying a stable foundation for subsequent assembly stages. It also significantly reduces processing time compared to traditional single-end grinding, enhancing batch production efficiency.
As a fully automated machine, the SX150-12YL operates without human intervention throughout the entire machining process. Its integrated automatic loading/unloading system, adaptive parameter adjustment module, and automatic grinding wheel compensation/dressing function automatically match grinding parameters to the specific requirements of different connecting rod specifications. Additionally, the integrated MARPOSS measurement system performs real-time dimensional inspection of processed components. It automatically isolates non-conforming products, records relevant data, and establishes a complete quality traceability chain, ensuring the qualification rate of every connecting rod leaving the factory.
For intelligent control, the SX150-12YL employs innovative algorithms to dynamically assess grinding wheel wear and precisely determine optimal dressing intervals. This ensures machining accuracy while significantly extending wheel lifespan and reducing consumable costs. The machine also features comprehensive data storage and analysis capabilities, retaining one month of processing data. This enables operators to retrospectively review production processes, providing data-driven support for quality optimization and process improvements in batch production. Additionally, the equipment incorporates a dual-tier quality warning mechanism. Upon detecting two consecutive non-conforming parts, the system automatically triggers a shutdown alarm, preventing batch production of defective items.
The SX150-12YL prioritizes safety and stability in its structural design. The machining area features a fully enclosed protective enclosure with electrically controlled door locks, preventing accidental contact with moving components during operation and ensuring operator safety. The workpiece transfer system utilizes a specialized step-channel structure that can be flexibly extended to accommodate production line layouts, adapting to various production scales. Additionally, the equipment incorporates a constant-temperature cooling system that precisely controls the grinding zone temperature, minimizing thermal deformation's impact on machining accuracy. Thermal insulation treatment of critical components further enhances operational stability, ensuring consistent precision during prolonged processing.
In terms of machining precision metrics, the SX150-12YL demonstrates outstanding performance: connecting rod parallelism error is controlled within 0.01mm, flatness precision reaches 0.01mm, thickness deviation does not exceed 0.02mm, and surface roughness achieves Ra 0.8μm. These specifications fully meet the stringent requirements for precision fit in engine connecting rods. Although designed primarily for connecting rod machining, this equipment can be adapted for dual-surface grinding of other high-precision components like bearings and gears by swapping specialized fixtures. Its versatile functionality helps manufacturers reduce equipment investment costs for processing diverse parts.
As a critical piece of equipment in engine manufacturing, the SX150-12YL integrates precision mechanical structures, intelligent control systems, and ergonomic design to advance automation and smart upgrades in connecting rod processing. This not only enhances production efficiency and product quality stability but also provides essential equipment support for the manufacturing industry's shift toward high-end and precision development. Against the backdrop of continuous pursuit for higher efficiency and energy savings in engine performance, the technological evolution of such high-precision grinding equipment will further elevate the manufacturing standards of core engine components.
