CCMT1204 Cast Iron Cutting Knives, Tungsten Carbide Inserts with CVD Coating

About Tungsten Carbide Turning Inserts

Carbide turning tools are the tools with a cutting blade and used for turning machining, it is widely applied to lathe cutting. The working part of a turning tool is the part to produce and dispose the cutting chips, including blade, the structure to break and smash or roll up and the room to dispose or store the chips, the cutting fluid channel. The application of tungsten carbide in this area is widely because of the super high hardness and corrosion resistant advantages, which make the turning blade very sharp and wear resistant, long life time, and can be machined to be very precision to different use.

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. 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: the solution when a insert is failed on performance:

• Chip jamming because of facing towards shoulder
• The chips are deflected against the cutting edge
• Not optimized feed or feed direction​

Solution:

• Switch off coolant or apply coolant copiously to obtain an even temperature level
• Decrease cutting speed
• Select grade with thinner coating (PVD)

2. Breakage

Cause:

• Excessive wear
• Wrong choice of grade (too tough/hard)
• Wrong cutting data

Solution:

• Change operation path (to avoid facing towards shoulder)
• Change feed
• Select a PVD-coated grade
• Select an insert geometry that alters the chip flow
