The ZnO nanoparticles were obtained by ball milling of commercial grade ZnO powder at 250 rpm for 20 h and studied their structural, microstructure, optical and photocatalytic properties. Due to ball milling significant decrease in lattice parameters and average crystalline size is noticed for ...

Mill Machining, Milling Process, Horizontal Vertical Milling Machines Definition. Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. With the help of the milling machines one can perform many operations and functions starting from small objects to large ones.
