Stainless steel is a common yet “ difficult ” material.
Due to its high toughness, high hardness, and poor thermal conductivity, many people often encounter problems such as tool sticking, built-up edge, and rapid tool wear when processing stainless steel. So, how to efficiently and easily turn stainless steel?
The answer is simple: choose a blade specifically optimized for stainless steel, such as TNMG1604-MA or TNMG1604-MS 。
With its excellent chip removal performance, wear resistance, and cost advantages, this blade has become the first choice for many customers.
What is TNMG1604 ？
Let's briefly understand the meaning of the model:
T ：Equilateral triangular blade, three corners
N ： 0° back rake angle, high rigidity
M ：Medium precision grade
G ：Double-sided blade, with hole design
1604 ：Side length 16mm ，Thickness 4.76mm ，Nose radius (depending on the model, there are 0.4/0.8/1.2 etc.)
If the suffix is MA/MS ，then it is a chip breaker specifically for stainless steel. It can not only easily cope with the problem of tool sticking in stainless steel, but also maintain good cutting performance at higher speeds.
TNMG1604 Four major advantages of processing stainless steel
- Smooth chip breaking, say goodbye to tool sticking
The most troublesome problem in stainless steel processing is built-up edge and tool sticking 。 TNMG1604-MS/MA The blade uses a chip breaker designed specifically for stainless steel, which can effectively control the chip flow direction
- Wear-resistant and heat-resistant, longer tool life
We use a high-toughness cemented carbide matrix, combined with nano-scale PVD coating (such as TiAlN or TiCN ), making the blade still sharp at high temperatures
Effectively prevent chipping, wear and oxidation 。Processing 304、316、321 stainless steel, the blade life is significantly longer.
3、 Light and fast cutting, small machine load
Thanks to MA/MS the optimized design of the chip breaker, the blade is light and fast, and the cutting resistance is small, effectively reducing the machine load and energy consumption 。It is particularly outstanding in continuous processing of CNC lathes.
Stainless steel TNMG and cast iron TNMG comparison
Many customers will ask: “ I used to use TNMG160404-HK to process cast iron, can I directly use it to machine stainless steel? ”
The answer is: Not recommended.
