Wiper inserts have a longer secondary cutting edge than general inserts, and have a structure that protrudes slightly more than other cutting edges during installation.
Therefore, the effect of always smoothing the machined surface can be obtained, and the accuracy of the finished surface can be improved.
Basically, one wiper insert is set in the cutting edge of multiple general inserts.
The key is to keep the feed amount per revolution (mm/rev) within the length of the secondary cutting edge.
However, in environments where the feed amount per revolution is originally set to a large amount, such as a large-diameter cutter, multiple wiper inserts may be set and used.
