Failure to observe the precautions may Warning cause serious damage to human body. Revolution Balance quality grade G ISO 1940-1/8821 (min-1) (JIS B0905) Warning about max. revolution indicated on main body 1. Do not use the end mill or cutter at the maximum revolution or higher since the centrifugal force may cause inserts and parts to scatter or the ~20,000 G16 body may be damaged even under no load. 2. For actual practical revolution, please set within recommended cutting condition. ~30,000 G6.3 3. When using at a higher revolution (over 10,000min-1), refer to the table to adjust the balance of MECX and suitable arbor. 30,000~ G2.5 MECX Recommended cutting conditions fz (mm/t) Recommended insert grades (Vc: m/min) MEGACOAT MEGACOAT CVD Workpiece material NANO coated carbide JS chipbreaker JT chipbreaker PR1535 PR1225 PR1210 CA6535 M Carbon steel 0.04~0.08~0.1 0.06~0.1~0.12 ☆ 120~180~250 ★ 120~180~250 - - ☆ ★ Alloy steel 0.04~0.06~0.08 0.06~0.08~0.1 - - 100~160~220 100~160~220 ☆ ★ Mold steel 0.04~0.06~0.08 0.06~0.08~0.1 - - 80~140~180 80~140~180 Milling Stainless steel ★ ☆ 0.03~0.04~0.05 0.05~0.06~0.07 - - (Austenitic related) 100~160~200 100~160~200 Stainless steel ☆ ★ 0.03~0.04~0.05 0.05~0.06~0.1 - - (Martensitic related) 150~200~250 180~240~300 Stainless steel ★ 0.03~0.04~0.05 0.05~0.06~0.1 - - - (Precipitation hardening) 90~120~150 ★ Gray cast iron 0.04~0.08~0.1 0.08~0.1~0.15 - - - 120~180~250 ★ Nodular cast iron 0.04~0.06~0.08 0.08~0.1~0.12 - - - 100~150~200 ☆ ★ Ni-base heat-resistant alloys 0.03~0.04~0.05 0.05~0.06~0.07 - - 20~30~50 20~30~50 ★ ☆ Titanium alloys 0.04~0.06~0.08 0.08~0.1~0.12 - - 40~60~80 30~50~70 * Machining with coolant is recommended for Ni-base heat-resistant alloys and titanium alloys. ★: 1st Recommendation ☆: 2nd Recommendation M64
