As a grinding tool on the honing machine,the structure and performance of large honing head have a direct impact on the honing accuracy and honing efficiency because of its complex structure,large mass and worse working conditions.The inertia force caused by large mass has a great influence on its accuracy and kinematic stability.Based on the analysis of structure,working conditions and loading features,lightweight research of structure and material for the large Φ450mm double-feed honing head was carried o...
