always suggest setting this to 12 of the maximum machine feed speed So for a Version 1 machine this will be set to 15 mmsec and for a version 2 machine you will set this to 25 mmsec Once the job is

machining a feature As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is usedMill Linings Ball and Pebble Mills may be lined with rubber ceramic and wear resistant metallic liners Grinding Media Mills may be charged with ceramic steel and alloy steel grinding media These are spherical or cylindrical in shape and range from 6 mm to 100 mm in sizeA 10degree entering angle is used on highfeed and plunge milling cutters A thin chip is generated that allows for very high feeds per tooth f z at small depths of cut and consequently extreme table feeds v f The dominating axial cutting force is directed towards the spindle which stabilizes itThe design of a ball mill can vary significantly depending on the size the equipment used to load the starting material feeders and the system for discharging the output product The size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 05 to 35 TheFeed 2 x 01 x 18000 3600 mm per min If the RPM were increased to 24000 RPM the new feed rate would work out to be Feed 2 x 01 x 24000
