Features of our carbide inserts?

1. Effective chip control & perfect turning surface
Provides perfect turning surface of the workpiece. Excellent and reasonable Chipbreaker design, removing the chips smoothly and taking away the heat of the rubs of the workpiece.

2. Higher production, long tool life
Long tool life means you need less time changing the inserts while machining. A reliable and safe performance every time.

3. Less tool breakage, cost down of each component
Saving costs and reducing the cost of each component to increase the profits. The high wear resistance makes the long service life of the carbide inserts, which means you could saving more budget on purchasing the inserts.

4. CVD coating ensures the high wear resistance
The layer of the CVD coating with the thickness around 8um-20um which guaranteed the high wear resistance.


Customer’s case: Cause and Solution when an insert is failed on performance

1.Surface finish
The surface looks and feels “hairy” and does not meet the tolerance requirements.

Cause:
-The chips are breaking against the component and marking the finished surface
-Hairy surface is caused by excessive notch wear on the cutting edge​
-Feed is too high, in combination with a nose radius that is too small, a rough surface​ is generated

Soulution
-Select a geometry which guides the chips away from the component
-Change entering angle
-Reduce depth of cut
-Select a positive tool system with a neutral angle of inclination
-Select a grade with better resistance to oxidation wear, for example a cermet grade.
-Reduce the cutting speed​
-Select a wiper insert or a larger nose radius
-Reduce feed

2.Crater wear
Cause:
-Too high cutting speed and/or feed
-Chip breaker too narrow
-Chemical dissolution or abrasive wear
-Wear resistance too low

Solution:
-Reduce cutting speed or feed
-Select a more wear resistant grade
-Select a more open/positive geometry
