MEC ■ When using inserts with corner-R(re)1.6 or larger, additional modifications of the cutter body will be necessary. Ref. to the chart below for the recommended modifications. (Additional grind off is not necessary when corner-R(re) is 1.2mm or less.) Insert Corner-R(rε)（mm） Additional Processing * Round- shaped additional processing is recommended. Dimension to Body Corner (mm) When applying chamfer shaped additional processing, do not cut away too much. 1.6 R1.0 2.0 Additionally Insert with large processed Body corner corner-R(rε) Pre-processing Post-processing 2.4 R1.2 3.1 R1.6 4.0 R2.5 ◆ Recommended Cutting Conditions ・JT Chipbreaker fz (mm/t) Recommended Insert Grades (Cutting Speed Vc : m/min) Workpiece Toolholder Description Cermet MEGACOAT MEGACOAT PVD Coated CVD Coated Material NANO Carbide Carbide MEC10~MEC19 MEC20~MEC40 TN100M PR1535 PR1225 PR1210 PR830 CA6535 MEC040R~MEC160R Carbon Steel 0.06 ~ 0.1 ~ 0.15 0.08 ~ 0.15 ~ 0.25 ☆ ☆ ★ - ☆ - 120 ~ 160 ~ 200 120 ~ 180 ~ 250 120 ~ 180 ~ 250 120 ~ 160 ~ 200 Alloy Steel 0.06 ~ 0.1 ~ 0.12 0.08 ~ 0.15 ~ 0.2 ☆ ☆ ★ - ☆ - 100 ~ 140 ~ 180 100 ~ 160 ~ 220 100 ~ 160 ~ 220 100 ~ 140 ~ 180 Mold Steel 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.12 ~ 0.2 ☆ ☆ ★ - ☆ - 80 ~ 120 ~ 150 80 ~ 140 ~ 180 80 ~ 140 ~ 180 80 ~ 120 ~ 150 M Stainless Steel ☆ ☆ ☆ (Austenitic related) 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.12 ~ 0.15 - 100 ~ 160 ~ 200 100 ~ 160 ~ 200 - 100 ~ 140 ~ 180 - Stainless Steel 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.12 ~ 0.2 - ☆ - - - ★ Milling (Martensitic related) 150 ~ 200 ~ 250 180 ~ 240 ~ 300 Stainless Steel 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.12 ~ 0.2 - ★ - - - - (Precipitation Hardening) 90 ~ 120 ~ 150 Inserts ★ Lead Angle Gray Cast Iron 0.06 ~ 0.1 ~ 0.15 0.08 ~ 0.18 ~ 0.25 - - - 120 ~ 180 ~ 250 - - 45°/20° Lead Angle ★ 15° Nodular Cast Iron 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.15 ~ 0.2 - - - - - Lead Angle 100 ~ 150 ~ 200 0° Ni-base heat-resistant 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.12 ~ 0.15 - ☆ - - - ★ High Feed 20 ~ 30 ~ 50 20 ~ 30 ~ 50 alloys Multi- Function ☆ ☆ Titanium Alloys 0.06 ~ 0.08 ~ 0.1 0.08 ~ 0.15 ~ 0.2 - 40 ~ 60 ~ 80 - 30 ~ 50 ~ 70 - - Slot Mill Ball-nose * The bold-faced number indicates a center value of recommended cutting condition.
