1. "High input" milling strategy
Modern rough skin milling cutters are often used in conjunction with the High Feed Milling strategy. This strategy adopts a small cutting depth (very small radial cutting depth) and extremely high feed rate, mainly relying on the specific angle of the tool edge for cutting. It can achieve extremely high metal removal rates with very low cutting forces and significantly extend tool life.
2. Before precision machining, there must be a margin left
The surface of the workpiece processed by a rough milling cutter will leave obvious, wavy step marks, and the surface is very rough. Therefore, sufficient allowance (usually 0.2-1.0mm) must be left for subsequent precision machining tools such as flat head milling cutters, round nose milling cutters, or ball end milling cutters to ensure a smooth surface after precision machining.
3. Powerful chip removal and cooling
Rough machining generates a large amount of chips, and it is necessary to ensure that cutting fluid or air gun can effectively wash away the chips from the machining area to avoid secondary cutting.
