Cemented Carbide Turning Inserts WNMG080408GH for Heat Resistant Alloys Semi Finishing with Nano PVD Coating
Application:
- ISO S materials, preferred for semi-finishing of superalloys, Heat
Resistant Alloys.
Feature Advantage:
- Chipbreaker SM:
- G-class precision chipbreaker type, precision grinding.
- The chipbreaker surface is smooth, the insert is smooth, and the
chip breaking is good.
- The cutting edge is sharp and the cutting resistance is small,
which can effectively reduce the groove wear.
- The cutting edge adopts a variable rake angle design to increase
the edge strength at large depth of cut. As the depth of cut
increases, the edge strength increases.
- The large groove width combined with the unique edge reinforcement
design not only has excellent chip breaking performance, but also
effectively improves the edge strength.

Technical Information:
- Material Classification: S1.0 - 3.0
- Heat resistant alloys can be divided into three groups:
- Cobalt based alloy:
- Cobalt-based alloys have the best high temperature properties and
corrosion resistance and are mainly used in the medical industry.
- Iron-based alloy:
- Iron-based alloys have evolved from austenitic stainless steels
with the highest temperature strength characteristics.
- Nickel-based alloy:
- The most widely used. More than 50% of the weight in aircraft
engines is made of nickel-based alloys. Typical materials are
Inconel 718, 706 Waspalloy, Udimet 720, etc.
- Characteristics: Increased alloy content (Co, Ni), which has better
heat resistance and higher corrosion resistance, and increased
tensile strength.
- State: annealing, solution treatment, aging, rolling, forging,
casting.
- Machining performance:
- Due to the chemical nature of the alloy and the specific smelting
process used in the manufacturing process, the physical properties
and processing properties of each material vary considerably.
- Annealing and aging treatment have a large impact on subsequent
processing characteristics.
- Difficult chip control, cutting force and required power are very
high.
- The processing difficulty of cutting performance increases in the
following order: iron-based alloy, nickel-based alloy, cobalt-based
alloy.
- Poor thermal conductivity and high strength during processing can
cause high temperatures. The high strength, work hardening and
adhesion hardening properties result in groove wear at the maximum
depth of cut and the cutting edge in an extremely harsh
environment.
- All materials have high strength at high temperatures and produce
jagged chips during the cutting process, which results in high
dynamic cutting forces.
- In general, use a small lead angle blade, such as a round blade,
and select the positive rake insert geometry.
- Always use coolant. The coolant flow should be high and spray
directly onto the cutting edge.
Recommended Cutting Parameters:
- The following cutting parameters are the recommended range values.
Appropriate adjustments and selections should be considered after
considering the following factors:
- Specific physical properties of the material being processed
- The actual condition of the part blank
- Power and rigidity of the machine tool
- Clamping rigidity of tools and workpieces
- Balance between tool life and machining efficiency
