the end mill speed is calculated with the following formula: rpm 3.14 mm) example calculation: vc 500 mmin mm 19904 rpm If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.effect of ball milling parameters on the synthesization of carbon nanotube aluminium nano composite p.537. tensile properties evaluation of paper pulp packaging at different sections and orientations on the egg tray p.542. comparative study between candida antarctica
although tailored wet ball milling can be an efficient method to produce a large quantity of two-dimensional nanomaterials, such as boron nitride nanosheets, milling parameters including milling speed, ball-to-powder ratio, milling ball size and milling agent, are important for optimization of exfoliation efficiency and production yield.the milling process definitions cutting speed,v indicates the surface speed at which the cutting edge machines the workpiece. effective or true cutting speed, indicates the surface speed at the effective diameter .this value is necessary for determining the true cutting data at the actual depth of cut .this is a particularly important value when using round insert cutters

the ball mill system consists of one turn disc and two or four bowls. the turn disc rotates in one direction while the bowls rotate in the opposite direction. the centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling As a construction, a ball milling device usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel around the center axis. the mill is driven by a girth gear bolted to the shell of the quantitative estimations of these parameters can be found in 23.
