Feature Advantage:
- Precision five-axis grinding machine grinding, dimensional
stability, high indexing accuracy.
- Optimized insert construction and a well-matched PVD coating ensure
insert toughness and longevity while meeting the high feed
requirements for efficient milling.
- The insert is multi-optimized by the choice of base material,
channel structure and coating while ensuring strength. It has
superior toughness and can adapt to very large feeds (max 2.5
mm/z). Even if the insert is severely worn, there will be no
breakage, and the cutter head will be well protected from damage.
- Under normal feed conditions, the surface quality of the process
can also be improved.
- The insert can be used in a variety of milling operations:
- High efficiency milling in the plane.
- Reduce the machining feed rate when chamfering or spiral machining.
- When drilling and milling, set the axial feed to 0.2 mm / rev or
less.
- There may be long chips flying out during drilling and milling, so
be careful.
- When performing spiral reaming, the depth of cut per round cannot
exceed the maximum depth of cut ap.
- In addition to the above processing, it can also be used for
embedded milling.

Milling Application Tips:
- Check power capability and machine rigidity and ensure that the
machine can make the most of the required tool diameter.
- Cutting on the spindle with the shortest possible tool overhang.
- Use the correct tool pitch for cutting to minimize the number of
inserts involved in the cut to avoid vibration, while on the other
hand, for narrow workpieces or when milling exceeds space, make
sure the inserts are adequate.
- Be sure to use the correct feed per blade to achieve the correct
cutting action with the recommended maximum chip thickness.
- Climb milling is recommended whenever possible.
- In any case, the use of indexable inserts with positive rake
grooves provides smooth cutting and lowest power consumption.
- Select the correct tool diameter that corresponds to the width of
the workpiece.
- Choose the most appropriate lead angle.
- Correctly position and hold the milling cutter.
- If you need to consider the use of coolant, milling without coolant
can generally be done very well.
- Follow blade maintenance recommendations and monitor tool wear.
Recommended Cutting Parameters:
- The following cutting parameters are recommended range values and
should be adjusted as appropriate 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
