3 Comprehensive PD milling coating grae K-Gol Coating layer (,PC3545,PC6510) TiN Goo lubrication, Chipping ree TiAlN Goo wear resistance Exclusive substrates as per each application Optimal wear-resistance an shock resistance 1. TiAlN : High spee an ry machining => High prouctivity 2. Reinorce wear-resistance rom conventional TiAlN coating layer => Wie application rom inishing to roughing 3. TiN Coating layer : Low cutting orce, Goo surace inish => Long tool lie : TiAlN (Wear resistance) + TiN (Lubrication) = Chipping ree uner high spee 4. Easy istinguish lank wear => High prouctivity : Yellow color o Coating layer makes it easier to istinguish => Guarantee appropriate tool change => High prouctivity K-Gol Machinability K-Gol 130% K-Gol (9 Pass) TiAIN % Machinability(harness & toughness) TiAlN (5 Pass) => K-Gol : better reliability + less ailure + lower cost
