How do you decide between using a ball mill or a rod mill Many investigators have attributed the selective grinding of rods to line contact Other things should be considered In the two pairs of tests shown in table 12 the relative deportment of large balls and small rods in batch wet grinding is shown The two loads had the same volume
Oct 01 2003 · Consider a medical implant such as a ball joint for a hip Fluids are undesirable where there is the fear of contamination The workpiece s suitability for a dry process also depends on the material A cutting fluid can be superfluous for cutting most alloys of cast iron and carbon and alloyed steel for example
So modern milling cutters tend to run with light depth of cut but very high speeds and feeds Also with faster speeds while the heat created is intense each cut can be over very quickly Ten or 15 years ago on steel we would be running 140 to 150m per minute surface speed wet i e with coolant
In cutting operations usually the value of Over Run is taken as 5 mm In facing operation to face the width of job w respective cuts are required if D the Diameter of cutter is less than w the width of job And usually the Approach Length is taken as 0 5 D and Over Run as 7 mm in this case Total Time for Milling The time for milling the
Mar 01 2008 · I never tried milling inconel with the ceramics My tungaloy guy back then didnt recommend it for our application But I also saved a ton of time and money when he turned me on to the ceramic 1 2 dia button inserts for rough turning I couldnt believe anything could cut inconel that fast I think that grade was M101S or something like that Tim
Oct 15 2000 · However one problem with a ball nose tool is that its shape produces vanishingly small cutting speeds sfm approaching 0 near the ball s tip This characteristic of ball nose tools creates a danger whenever two conditions are met A the cut is very light and B the workpiece surface is nearly perpendicular to the axis of the tool
