Wiper inserts for turning
The commonly noted key advantages for wiper turning inserts are:
1) Doubling of feed per revolution while still achieving the same surface finish as with a standard radius turning insert. This means a doubling of productivity for the operation. It can also translate into longer tool life for a finishing insert because the in-cut time per component is reduced by 50 percent.
2) By substituting a wiper insert instead of a standard radius geometry insert and keeping the same feed per revolution, the surface finish produced will be two times better. For example, instead of a 64 RMS, the workpiece will have a 32 RMS. In some cases this can mean a subsequent grinding operation can be eliminated.
