External Triangle Carbide Inserts TCMT Lathe Cutting Inserts For Nodular Cast Iron

External Turning Insert TCMT Lathe Cutting Inserts For Nodular Cast Iron

The introduction of Grade:

YBC251

The substrate with good toughness and high security of cutting edge,in optimal combinatin with coating composed of MT-TiCN,thick layer of Al2O3 and TiN makes it suitable for steel semi-finishing.

YBC252

** Comprising of thick TiCN and thick AL2O3 coating,the grade has high capability against plastic deformation and good hardness 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.

YBM253

** Ultra-fine grain coating technology provides better wear resistance and toughness;

** Improved remain internal stress design ensures good toughness and anti-cracking performance;

** Polishing treatment on coating surface makes it suitable for cutting adhesive materials.

YBD152

**CVD coated grade,which is the combination of hard sustrate 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.

Significant results:

1. Working efficiency has been improved.Both the coating and the substrate are suitbable for machining cast iron at high speed and high feed rate.cutting speed can be increased by 30%-40%.

2. Cost is reduced as tool life is increased by 40%-50%

3. High machining stability.
