Description

Technical Field

[0001] The utility model relates to the technical field of round nose knives, in particular to a combined graphite coating alloy round nose knife. Background Art

[0002] Round nose cutter refers to a cutter whose arc length is greater than 1 / 4 of a circle. Round nose cutter, also known as flat bottom R cutter, is a common cutter in CNC machining. It features a circular arc cutting edge, which allows it to transition smoothly during machining, and is particularly suitable for roughing, flat surface finishing, and curved surface finishing.
