The SX150-12YL fully automatic double disc grinding machine is specifically engineered for engine connecting rod production lines. It precisely meets the machining process requirements for both diesel and gasoline engine connecting rods, providing critical support for automated connecting rod production line construction. Simultaneously, it offers tailored solutions for high-precision workpieces like bearings and gears, as well as production lines demanding high automation.
The SX150-12YL features full-process autonomous management capabilities, encompassing automatic calculation and analysis, automatic loading/unloading, automatic grinding, automatic compensation, automatic dressing, automatic cleaning, automatic sludge removal, and automatic lubrication. Equipped with a MARPOSS measurement system, it enables inspection, automatic rejection of defective parts, and automatic transfer of finished products to subsequent processes—all without manual intervention, significantly enhancing production intelligence.
In terms of core performance and safety assurance, this grinding machine offers distinct advantages. It employs closed-loop control and online automatic measurement, with real-time feedback of measurement data to the system for automatic compensation. When out-of-tolerance conditions occur, it processes according to connecting rod machining requirements while triggering audible and visual alarms and recording faults. The machine features historical data query capabilities, allowing users to view and statistically analyze connecting rod machining dimensional data from the past month, as well as check equipment status and operation logs. Innovative algorithms enable coordinated analysis of dimensional stability and grinding wheel compensation, precisely determining wheel dressing intervals to maximize wheel utilization.
The equipment incorporates dedicated step-feed conveyors with 2-meter-long loading and unloading sections (extendable as needed), storing and transporting raw connecting rods and finished parts respectively. The processing area is fully enclosed with electrically controlled safety doors that halt operation upon forced opening. A scrap collection bin is positioned at the discharge point, automatically isolating and recording out-of-tolerance parts. Feeding automatically halts with an alarm upon two consecutive scrap parts. Grinding wheels and fixtures incorporate collision prevention features. Dual mechanical and electrical alarms activate when wheel wear reaches limit dimensions, triggering automatic feeding cessation. Additionally, the equipment incorporates thermal insulation to mitigate grinding heat effects on stability. It features an independent coolant circulation system with temperature control, a magnetic drum separator, and an inclined belt filter (filtration precision <15μm), complete with water level alarm.
