The fi gure in bold font is center value of the recommended cutting conditions. Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation. When fi nishing with LD type and FL type with wiper edge, reduce feed rate to fz=0.10.3mm/t or less. For machining center equivalent to BT30, reduce feed rate to 25% or less of the recommended condition. For slotting, internal coolant or center through coolant is recommended.

When drilling, reduce feed rate per revolution to under f=0.2mm/rev. Unit:mm Center core Note for vertical milling (Plunging) Available for vertical milling Vertical milling (Plunging) Note for all 3D machining Insert Ramping Contouring (rising wall angle) Vertical Helical Milling Pocketing Maximum Maximum Width of Cut (ae) GM (90 ) OMT10 8mm OMT14 1mm For vertical milling (plunging), reduce feed rate to fz=0.2mm/t or less. LD (65 ) FL (80 ) ome applications are not available depending on insert shape. For FL and LD type, there is a limit of rising wall angle when conducting contouring.
