FUNCTION OF TOOL FEATURES FOR FACE MILLING
FINISHED SURFACE
Cutting Edge Run-out Accuracy
Cutting edge run-out accuracy of indexable inserts on the cutter body greatly affects the surface finish and tool life.
Improve Finished Surface Roughness
Sub Cutting Edge Run-out
and Finished Surface
Since Mitsubishi Materials' normal sub cutting edge width is 1.4mm, and the sub cutting edges are set parallel to the face of a milling cutter, theoretically the finished surface accuracy should be maintained even if run-out accuracy is low.
- Replace one or two normal inserts with wiper inserts.
- Wiper inserts are set to protrude by 0.03-0.1mm from the standard inserts.
How to Set a Wiper Insert
|
|
|
(a) One Corner Type Replace normal insert. |
(b) Two Corner Type
Replace normal insert. |
(c) Two Corner Type Use supporter for wiper insert. |
- Sub cutting edge length has to be longer than the feed per revolution.
*A sub cutting edge that is too long causes chatter.
- When the cutter diameter is large and feed per revolution is longer than the sub cutting edge of the wiper insert, use two or three wiper inserts.
- When using more than 1 wiper insert, run-out needs to be eliminated.
- Use a high hardness grade (high wear resistance) for wiper inserts.
