Apr 01 2008 · Because the tool is likely to be small a fast spindle may be needed to realize this cutting speed range. The use of a ballnose end mill for hard milling of complex die and mold surfaces only makes the need for high speed more likely. When a ballnose tool cuts at light axial depths of cut the tool does not cut on its full diameter.
