2020-9-7  High-speed ball-end milling operation. High speed machining center DMU 60P duoBlock with maximum spindle speed 12,000 r/min was selected to perform the high-speed ball-end milling operation of hardened cold working die steel AISI D2. New coated solid carbide ball-end milling cutter with two cutting edges was used during the dry milling process.

2021-3-8  Besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry).

2003-9-22  When high-speed ball end milling a cantilever-shaped thin plate, the vibration at the end of workpiece was severe and dominantly affected by cutter orientations. (2) In experiments, the most stable cutting was achieved with a vertical outward cutter orientation. (3)

We investigated the ability to selectively form products arising from a kinetic or a thermodynamic enolate under solvent-free high speed ball milling conditions. Using 2-methylcyclohexanone as the substrate and sodium hydroxide or lithium hexamethyldisilazide as the base, we were able to trap the thermodynamic or kinetic enolate in high selectivity.

2010-8-13  Mechanochemical treatment was performed by a high-speed ball-milling apparatus (High-G, Kurimoto Ltd., Japan) that operated for 3 h in an air atmosphere under various centrifugal forces. The phase evolution of the milled nanoparticles was characterized by X-ray diffraction (XRD; JDX-3530M, JEOL, Japan) using Ni filtered Cu-Kα radiation.
