Cutting edge run-out accuracy of indexable inserts on the cutter body greatly affects the surface finish and tool life.
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 normal insert with wiper insert.
• Wiper inserts are set to protrude by .0012 ― .004 inch from the standard inserts.
* Value depends on the cutting edge and insert combination.
