Research on the Cylinder Block Machining Technology of a New Medium-speed Diesel Engine

所研究的新一代中速柴油机机体内设计了滑油和冷却水通道,导致加工难度大幅度增加。阐述了利用组合刀具、高转速合金铣刀、抛物线深孔钻等刀具以及先进加工工艺,满足了机体的加工要求,提高了加工效率,避免了加工应力对机体关键部位加工质量的影响。在检测手段上,采用高精度测量工具和光学测量工具取代三坐标测量,完成对机体关键尺寸、关键部位的检测。

The lube oil and cooling water channel were designed for a new developed medium-speed diesel engine,which resulted in big difficulty in machining.Combined cutting tool,high-speed alloy milling cutter and parabola depth drill were applied as well as some advanced machining technology,which can satisfy the machining requirements of cylinder block and enhance efficiency,and avoid bad influence of machining stress on the key parts of cylinder block.High-precision measuring tool and optical instruments were employed instead of 3D measuring to accomplish the measuring of key dimensions and points of cylinder block.
