•Improving Surface Finish | Under the same machining conditions as conventional breakers, but with the feed rate increased, the surface finish of the work material can be improved. |
---|---|
•Improving Efficiency | High feed rates not only shortened machining times but also make it possible to combine roughing and finishing operations. |
•Increased Tool Life | When a change to high feed conditions, the time required to cut one component is decreased, thus more parts can be machined with each insert. In addition, the high feed rate prevents rubbing, therefore, delaying the progression of wear and increasing the tool life of the insert. |
•Improving Chip Control | Under high feed conditions, the chips generated become thicker and are more easily broken, thus, chip control is improved. |
The effects of wiper inserts on external machining, boring and facing.
* The surface roughness when machining at corner R or taper angle over 5°, is the same as machining with standard inserts.
A standard holders can be used.
(*A double clamp, high rigidity tool is recommended.)
Conventional machining programmes can be used.
(The CNMG • WNMG • CCMT types are based on the ISO/ANSI.)
Use a holder with end cutting angle 93° for improving wiper efficiency. A holder with end cutting angle 91° can improve wiper efficiency (see the following figure), however, there is no wiper efficiency with other end cutting angles (60°, 90°, 107°etc.).
When machining errors occur, please adjust the programme.
(The DNMX•TNMX types are not based on the ISO/ANSI. Please refer to the next page.)
*Necessary to maintain a correct taper.
Adjust the relief angle toward the normal line.
Note1) Adjust the angle toward the normal line in the case where the adjustment number is minus ( ' =60° ─ 70°) and is not machined completely.
*Necessary to maintain a correct corner radius.
Adjust the work diameter same as the taper to prevent over-cut.
In correcting corner radius:
It is not necessary to adjust the machining programme, however, machining errors can occur within max. ± .0012" due to correcting by an approximate number.
Corner Radius Correction
Input the correction number of each corner radius.
