YBM253
New CVD grade for high-efficiency machining of stainless steel
Widely applied in high-efficiency machining with high cutting depth and high feed rate
With advanced ultra-fine grain nano coating technology, the grade uses gradient alloy substrate with high
toughness.It demonstrates excellent capacity at cutting with high cutting depth, high feed rate and high speed.
Achieving both higher cutting speed and longer tool life
Black Diamond Inserts -Second generation of YBC
YBC152
Thick TiCN and thick Al2O3 coatings improve the impact toughness and abrasion resistance, which makes it
suitable for finishing and semi-finishing of steel at high speed. Cutting speed can increase by more than 25%, while
the tool life can increase by more than 30% at the same cutting speed
YBC252
Comprising of thick TiCN and thick Al2O3 coatings, the grade has high capability against plastic deformation
and goodhardness of cutting edge. It is preferred grade for machining of steel from finishing to roughing. Under
the same cutting conditions, the cutting speed can be increased by more than 25%, while the tool life can be
30% longer under the same cutting speed.
First choice for high-efficiency and highspeed machining of cast iron
Black Diamond Inserts YBD
The combination of thick coating and substrate with good hardness and impact resistance gives the inserts excellent impact resistance and stability under high temperature,
and improves wear resistance of inserts. Inserts also satisfythe requirements of high speed and high feed rate when machining cast iron.The appearance of shining full black is easily identified
YBD052
CVD coated grade, which is characterized by super fine grain and smooth surface, is the combination of hard
substrateand coating (extra thick Al2O3 + thick TiCN ). The grade is optimized for best wear resistance when
machining gray cast iron at high speed under dry condition.
YBD152
CVD coated grade, which is the combination of hard substrate and coating (medium thick Al2O3 + thick TiCN),
has good flaking resistance. It is suitable for turning of cast iron at high speed, and light intermittent cutting
can be supported even at moderate speed. It is also suitable for milling of cast iron.
YBD102
CVD coated grade, which is the combination of hard substrate and coating (thick Al2O3 + thick TiCN ), shows
excellent wear resistance and impact resistance when machining nodular cast iron at high speed.
YBD252
CVD coated grade, which is the combination of hard substrate and coating (medium thick Al2O3 + thick TiCN),
achieves the balance between wear resistance and toughness. It is suitable for wet milling of cast iron, which
requires toughness (such as nodular cast iron) at moderate or low speed. It is also suitable for intermittent turning.
