1) When machining curved parts, in order to ensure that the cutting edge of the tool is tangent to the machining contour at the cutting point and avoid interference between the cutting edge and the workpiece contour, ball end cutters are generally used. Two edge milling cutters are used for rough machining, and four edge milling cutters are used for semi precision machining and precision machining

2) When milling larger flat surfaces, in order to improve production efficiency and surface roughness, a disc milling cutter with embedded blades is generally used

3) Universal milling cutters are generally used when milling small flat surfaces or step surfaces

4) When milling keyways, in order to ensure the dimensional accuracy of the groove, a two bladed keyway milling cutter is generally used

5) During hole machining, drilling tools such as drill bits can be used for hole machining
