Insert characteristics 

FT-Low feed-Turning

edge inclination design, Ensure the sharp of the cutting edge;Suitable for Axial turning processing;

The design of the Take-up arm and chip breaker can deal with radial grooving, effectively control chip curling and flow direction;

Large rake angle design ensures the sharpness of the cutting edge

MT- Medium feed –Turning

Small edge width and edge inclination design, Ensure the edge strength and sharp of the cutting edge;Suitable for axial turning processing;

Big rake angle with cutting width design,Ensure the edge strength and reduce the chip force。

Chip-breaker design

Effectively control chip curling

FC-Low feed-Parting

Curved front cutting surface and large front angle design, create a sharp cutting edge;

3D chip pocket ensures good chip wrapping and removal effects;

V-shaped cutting edge design, Good for chip curling, suitable for low feed grooving.;

MC- Medium feed-Parting

Curved rake face, Adjust the edge land drop to ensure the sharpness and increases the cutting edge strengthen at the same time;

C type cutting edge,Ensure the sharp of the cutting edge, Suitable for medium feed cutting。

Gradient curled chip breaking,Control chips tightly curled to helical。

RC-High feed -Parting

Chamfer for cutting corner,Improve insert edge strength and tool life, in order to meet the high feed and interrupt processing;

Chip-breaker design,In order to control compact curl to spiral chip;

Big rake angle with cutting width design,Ensure the edge strength and reduce the chip force。

FG- Low feed -grooving

●Set a lager chip pocket in the middle of the cutting edge, in order to make room to release chip.at the front ridge ends,

●The ridge forms a certain angle with cutting edge, in order to control the chip discharge direction.

●The design of cutting width improves cutting strength.

MG- Medium feed -Grooving

Negative rake gradient curled chip breaking,Ensure the excellent control for chip spiral;

Chip-breaker design,In order to control compact curl to spiral chip;

Big rake angle with none or small cutting width design,Ensure the edge sharpness and reduce the chip force。

MR- Medium feed -Profiling

●The curved edge design improves the strength of the edge and enhances the smoothness of cutting;

●The flat multi-gradual gradual cutting arm design, ensure good Chip breaking

OR-Precision feed -Profiling

●Sharp edge design to ensure good surface workpiece quality;

●Water drop type heat sink design to increase the contact area of cutting fluid.

stability:

On the basis of V-shaped positioning, combined with the design of inclined sections and platforms at both ends, it can effectively reduce the axial machining of the blade, resulting in lateral displacement and torsion. In addition, by applying force distribution, the force area of the blade is larger and m ore uniform, reducing the risk of blade fracture and improving machining stability.
