CNMG1204 PVD Coating Turning Tungsten Carbide Inserts For Stainless Steel Finishing

About Tungsten Carbide Inserts
Carbide insert is made of tungsten carbide, which is a kind of alloy material made of refractory metal hard compound and binding metal through powder metallurgy technology.Carbide insert has good hardness and wear resistance, good strength and toughness. Carbide insert also has heat resistance, corrosion resistance and a series of other excellent properties.Especially the hardness and wear resistance of carbide insert, carbide insert still has a good hardness at 1000 ℃. Carbide insert mainly uses solid cemented carbide as the matrix. Carbide insert also needs multi-channel production process to finish. Carbide insert, as the teeth of modern industry, plays a fundamental role in the development of the manufacturing.

Grades recommendation:


The high toughness substrate with TiALSIN coating ofultrafine grain size, is univeral and suitable for the processing of stainless steel and high temperature alloy.

PVD coating

Features of our carbide inserts

1. 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.

2. 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.

3. 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.

4. PVD coating ensures the non-stick performance
The layer of the PVD coating with the thickness around 2.5um-4um which guaranteed that the stainless steel grinding dust won't stock on the inserts, thus can take off the heat and protect the inserts.

Factors that influences chip breaking

  • Insert geometry: Based on the width of chip room and the design of micro- and macro geometry, the chip will be open or more compressed
  • Nose radius: Smaller nose radius controls the chip more than a bigger nose radius
  • Entering (lead) angle: Depending on angle, the chip is directed in different ways; towards shoulder or out from shoulder
  • Cutting depth: Depending on the workpiece material, a larger cutting depth will influence the chip breaking, leading to bigger forces to break and remove the chip
  • Feed: A higher feed will in general create stronger chips. Can in some cases help chip breaking and chip control
  • Cutting speed: Change of cutting speed can influence the chip breaking performance
  • Material: A short chipping material (for example cast iron) is in general easy to machine. For materials with excellent mechanical strength and resistance to creep (the tendency for solids to slowly move or deform under stress, for example, Inconel), the chip breaking is of greater concern
