ROMICRON Inserts

When boring as for lathe manufacturers work, the surfacequality is largely determined by the feed f andinsert radius
f 2 r .The corner radius on the insert leavesgrooves on the workpiece surface.The raw depth
R t = 125 x r Rfr R
t t is produced by the feed f and the corner radius r . This produces the feed f with:
t x r 125f =R Achievable surface quality for fine drilling
