Black CVD Coating DNMG1506 External Turning Carbide Inserts With Excellent Chip Control

What is tungsten carbide inserts?

Tungsten carbide inserts mainly include turning inserts, milling inserts, grooving inserts, parting inserts, threading inserts, drilling inserts ect.

with CVD or PVD coating, have a good performence in metal cutting.

Excellent chip control for steel machining . Provides perfect turning surface of the workpiece:

Models introduction for Steel machining:

Different chipbreakers:

Grades recommendation:

Contrast Advantage/Benefits of choosing our carbide inserts:

1. High wear resistance with CVD coating.
CVD coating with the thickness around 8um-20um which guaranteed the high wear resistance.

2. Wonderful chip control & perfect turning surface

Machining 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. Long tool life, higher production efficiency.
Long tool life means you need less time changing the inserts while machining. A reliable and safe performance every time.

4. 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 tool life of the carbide inserts, which means you could saving more budget on purchasing the inserts.

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

Quality control:

Technical support and after-sale service:

Our company can providing the following technical service for customers:

1: Recommending more suitable processing parameters.

2: According to the workpiece design, material and CNC machine feed rate, cutting speed we can recommending a full set of practical scheme.

3: Suggsting more suitable model to replace the brands of Japan, Korea and so on.

4. We can offer together with tool holder.
