Tungsten Carbide Inserts

1, Inserts for processing steel

ZZHardmetal

is a professional manufacture of cemented carbide cutting tools. Our turning inserts for steel processing with imported raw powder materials, through a special sintering process, have a peculiar gradient cobalt-rich on surface of the substrates which can ensure the inserts’ high performance when finishing the CVD coating. Our CVD coating is the most advanced in the world. The coating materials are MT-TiCN0-Al2O3 with thickness of 14um, which have high abrasion resistance. After special management on the surface of the coating inserts, the internal stress and surfaceness of coating were reduce while cutting resistance was also cut down. Our ZPS series grade can cutting steel and alloy steel from finish machining to semi-finish and rough maching.

Advantages:

Cobalt-rich structure on the surface of the substrate makes the inserts’ edge safety.

a-Al2O3 coating makes the inserts high stability, high abrasive resistance and high resistance of plastic deformation.

Special surface management makes the internal stress reduced and small surfaceness of coating.

2, Inserts for Processing Aluminium

Grade	Density (g/cm3)	Hardness (HRA)	Bending Strength (N/mm2)	Performance&Applications
ZU810	14.5~15.0	>92.8	3200	Ultra-fine cenmented carbide, be used for continuously and discontinuously cutting for Reflectal, Birmasil(Si<12%)
ZPU109	Cemented carbide coating grade with DLC coating. It can minimize Built-up edge and get a good finished surface in a wide range of cutting speed. With little cutting resistance, it applies to high speed cutting for all Aluminium Alloy.

3, Inserts for processing Cast Iron

The substrate of turning inserts for cutting cast iron is ultra fine grain carbitle, which is high hardness, high abrasive resistance and cutting-edge safety the inserts for cutting cast iron bear shock caused by non-uniform abscess of work-piece. The coating is CVD-MT-TiCN-Al2O3 owning ultra-high abrasive resistance. Such coating inserts can be used for dry cutting the special coating treatment can reduce the coating stress coarseness of coating surface and cutting resistence force. Grade ZPC101 is suitable for finishing mediam and roughing cutting of gray cast uron and ductile iron.

4, Threading Inserts

The indexable threading cutting tools are suitable to cutting various kinds of metal such as steel, cast iron. Threading products with different standards. e.g. Partial profile

60°, 55°,ISO Metric, UN,Withworth, BSPT,NPT,API threada etc.
