What is a ball nose end mill

It belongs to a kind of integral cemented carbide end mill. The ball end mill is point-contact machining, and the obtained machining surface precision is very high, and it occupies an important position in the CNC machining of free-form surfaces and molds. The ball edge of the ball end mill passes through the axis of the milling cutter, which can feed both laterally and axially, which can easily process complex curved surfaces and mold cavity surfaces, and occupy a large proportion of finishing tools. .
