ball end mills have a rounded nose and create a round-bottomed groove in milling tasks. also known as ball-nose end mills, they are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners. each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent flute end mills carbide, cobalt & hss. three flute end mills are used for higher feed rates than two flute end mills, and are often used in aluminum machining. they are commonly used in grooving operations where the chip is crowded. they are also used in non-ferrous milling applications where high feed rates are used.back to ball screw faq index. can use the y-axis accordion covers from my original mill? no, they will not work with the new mill saddle and ball leadscrews. the XY saddle is much taller on the ball screw mill than on the standard leadscrew mill, and therefore, the metal plates of the accordion covers were increased in size accordingly. back ball mills mine the point where the mill becomes a centrifuge is called the critical speed and ball mills usually operate at to of the critical speed ball mills are generally used to grind material inch and finer down to the particle size of to microns. read more
