Boron oxide adsorbed on alumina (B2O3/Al2O3 ) has been found to be a new and highly efficient heterogeneous catalyst for the synthesis of β-enamino ketones and esters by the enamination of various primary and secondary amines with β-dicarbonyl comp

Research on a novel approach to multi-axis line contact milling

Autor: Zhang Chang-fu, Wang Run-xiao, Yu Bingao, Wang Kunqi

Publikováno v: International Technology and Innovation Conference 2006 (ITIC 2006).

The principle of a novel multi-axis milling is presented. Peripheral edges of a cutter are in contact with the theoretical profile of a work-piece, and rotation of spindle drum imitates turning. Thus, the theoretical profile can be achieved with the
