A New Technology of Improving Surface Quality of Engine Cylinder

摘要

This paper introduces the new technology of ultrasonic vibration honing, and analyzes the cutting principle of ultrasonic honing in terms of cutting motion, grain performance and cutting quantity. Then, the applied effect used in the cast-iron cylinder of DY90 is introduced. The principle and the structure of this device are discussed. This new technology can further be used in micro-car's cylinder, can provides a high-productivity, high-quality for cast-iron cylinder.
