WNMG Peach-shaped carbide inserts—a type of turning insert that “holds up” better under unstable machining conditions.
In turning operations, many people have experienced this: the parameters are fine, and the machine tool is functioning normally, yet as soon as the cutting tool is engaged, it starts to vibrate, or the cutting insert quickly chips and wears out. This phenomenon is especially common during roughing and semi-finishing stages when machining steel, stainless steel, and even some more challenging materials.
At this point, the blade’s shape and structure often take precedence over parameters. WNMG Peach-shaped carbide insert It’s a “reliable” blade specifically designed for this type of operating condition.
The peach-shaped structure, put simply, means “even distribution of stress.”
WNMG It’s called a peach-shaped carbide insert primarily because its outline isn’t a standard straight-line rhombus but rather has a curved shape.
In actual cutting operations, an obvious advantage of this structure is that the cutting edge does not experience concentrated stress.
The intuitive impression of using it is:
The knife is moving relatively steadily.
It's not easy to suddenly shake it.
The blade edge is less likely to chip.
This “stable” sensation becomes even more pronounced, especially in situations involving intermittent cutting, irregular workpiece surfaces, or machines with moderate rigidity.
80 °Main cutting angle, more geared toward durability
WNMG The one adopted is 80 ° The principal cutting angle—this is what determines that it doesn’t pursue “ultra-sharpness” but instead leans toward robustness and durability.
In actual processing, this manifests as:
The blade is relatively thick.
Can withstand the cutting volume.
Don't worry about the knife cutting a little deeper.
The blade life is relatively stable.
Therefore, blades of this type are more commonly used for rough turning and semi-finishing rather than for the final finishing pass.
Compared to commonly used diamond-shaped turning tools, its applications are somewhat different.
If you’ve used it before in your daily life CNMG 、 CCMT This type of 80 ° Diamond-shaped turning tool, then switch to... WNMG It’ll feel a bit different.
Simply put:
Ordinary diamond-shaped turning tool:
Standard, universal, suitable for most conventional turning operations.
Peach-shaped turning tool ( WNMG ):
More vibration-resistant and more tolerant of unstable operating conditions.
When the machining process is prone to vibration, the workpiece profile changes frequently, or the material is relatively “hard to cut,” WNMG It often tends to be less troublesome.
Many groove types available, making it easy to select based on the material.
WNMG The series offers a variety of common groove types, and the selection process in practice is fairly straightforward:
MA Slot: Relatively stable; commonly used for conventional steel parts.
MS Slot: The cutting is relatively smooth.
TM Slot: Suitable for medium loads
PV Groove: Stainless steel is smoother to use.
43 Slot: Suitable for continuous machining or complex operating conditions.
The material has a relatively wide range of applicability.
WNMG Peach-shaped carbide inserts offer relatively broad material compatibility and commonly include:
Steel parts \ Stainless steel \ Hardened steel parts \ Stainless steel \ High-temperature alloy \ Some materials that are relatively difficult to machine
For workshops dealing with a variety of materials, this is very practical—there’s no need to frequently change tool types.
Where are peach-shaped turning inserts commonly used?
In actual processing, WNMG Commonly used in:
External cylindrical turning
Face turning
Contour-following machining
Rough turning and semi-finishing turning stages
Especially when you want the machining process to be more stable and less prone to unexpected issues, this would be a relatively suitable choice.
