Simplicity: Vertical milling machines also have the benefit of being generally less complex than horizontal milling machines, being both cheaper and easier to use and maintain for this reason. Versatility: With vertical machining centers there are some variances based on what type it is.

Our proposed safety flow chart for ballmilling reactions is presented in Figure 2 and at the laboratory scale focuses on the assessment of starting materials/reactants rather than whole reaction mixtures. It is proposed that assessment of the reaction to be milled starts in much the same way as that of a good practice
