Advantages of cast iron turning insert TNMG160404
In metal turning, how to choose a stable and wear-resistant turning insert or Turning Tool Insert directly affects the processing efficiency and workpiece quality use Lathe Insert.
When the processing object is cast iron material, the choice of tool is even more critical.
Today, let’s talk about a product with outstanding performance – TNMG160404 cast iron turning insert.
what turning insert TNMG160404 ?
TNMG160404 is a standard triangular indexable turning insert, which is designed from the ISO international coding system. The specific explanation is as follows:
T: Triangle, three sides are equal
N: No back angle (negative angle design)
M: Medium precision grade
G: Hole + double-sided grinding
160404: indicates the size (16mm blade side length, 4mm thickness, 0.4mm rounded corners)
This blade has a symmetrical shape and can be used on both sides. One blade can use six tool tips, which is very suitable for large-scale and continuous industrial processing scenarios.
Lathe Insert TNMG160404 has significant advantages in machining cast iron
Cast iron has the characteristics of high hardness, strong brittleness and high carbon content, which requires the blade to have high wear resistance, good anti-collapse and strong chip removal ability. TNMG160404 has these characteristics:
1. Excellent wear resistance
The TNMG160404 blades we use are mostly made of high-hardness cemented carbide (such as YG or special cast iron grades), with a Vickers hardness (HV) of up to 1800-2000, which allows the blade to remain sharp for a long time when facing high-wear gray cast iron and ductile iron.
2. Good chip breaking effect and continuous chipping
The matching chip breaker design can effectively break the short chips generated during cast iron processing quickly, avoid chips wrapping around the tool or workpiece, and improve processing efficiency.
3. Smooth cutting and strong anti-collapse ability
Cast iron is a brittle material and is prone to “collapse” during processing. TNMG’s negative angle design makes the blade more stable during the cutting process, effectively reducing the tip load and the risk of chipping.
4. Double-sided and multiple-use, economical and practical
TNMG160404 A blade can use 6 blade tips, which not only saves costs, but also reduces the frequency of tool change, which is particularly suitable for automated and mass production scenarios.
What materials are suitable for Turning Tool Insert TNMG to process?
In addition to cast iron, TNMG160404 is also suitable for processing a variety of materials, but the following types of materials are its “strengths”:
| Material Type | Processing performance |
| Gray cast iron (HT250, etc.) | Good chip removal and excellent surface finish |
| Ductile Iron (QT450) | The insert tip is stable and not prone to chipping |
| Quenched and tempered steel | Requires special material |
| Ordinary structural steel | Light cutting and stable processing |
In general, TNMG160404 performs best in machining cast iron materials, especially in conditions that require high-intensity continuous cutting.
If you are looking for an efficient and durable cast iron turning insert, try our TNMG160404. I believe it can become a “hardcore warrior” on your machining line.
