Where Dry Milling Makes Sense

Oct 15, 2000When a ball-nose tool is used, smooth finish requirements may call for coolant's use. Here, the coolant serves as a lubricant. The problem with a ball-nose tool is that the tip of the tool has no surface speed. When a typical ball-nose tool takes very light finishing cuts, material can become trapped in the web design in this low-speed region.
