METHOD FOR PROCESSING DIFFICULT-TO-CUT CAST IRON |
摘要 |
In a pilot hole (21) of a workpiece (20) made of a difficult-to-cut cast iron, a cutting tool (10) having a leading end to which a cutting insert (11) is attached is inserted to cut the surface of the wall of the pilot hole (21). At this time, the cutting tool (10) rotates about an axis (±) and also revolves about another axis (²), so that contouring is performed on the workpiece (20) by the tool (10). The cutting insert (11) is formed of a sintered body having a CBN content of not less than 85% by volume, and the cutting insert (11) has a thermal conductivity of not less than 100 W/(mK). |
