CNC inserts SNMG1204 tungsten carbide cutting tools for stainless steel machining:


About Carbide turning inserts:

Turning inserts employ highly engineered composite structures,coatings and geometry features to achieve great accuracy and high material removal rates .

The benefits of using replaceable inserts for turning tools include:

Some inserts can be indexed to use other edges when one becomes worn
Inserts are quickly and easily replaced at the machine.

Advantages of our inserts :

1.Imported raw powder materials.

2 .Our inserts have a peculiar gradient cobalt-rich on surface of the substrates which can ensure the inserts’ high performance when finishing the CVD coating.

3. The coating materials are MT-TiCN0-Al₂O₃ with thickness of 14-20μm, which have high abrasion resistance. After special management on the surface of the coating inserts, the internal stress and surfaceness of coating were reduced while cutting resistance was also cut down.

Customer’s case: when a insert is failed on performance:

1. Flank Wear
-Workpiece material contains high hardness chemical elements (tool steel, die steel)
Increase cutting speed if abnormal flank wear is caused by a very slow cutting speed.
Solution: Reduce cutting speed or feed rate or use more wear resistant grade

2. Crater Wear
-Workpiece material contains high hardness chemical elements
Solution: Reduce cutting speed or feed rate or use more wear resistant grade

3. Cracking
-Excessive feed rates when interrupted cutting
Solution : Reduce feed rate, Use tougher grade
