Our unique patented, Helix™ wiper concept is designed for optimization in finish machining.
It has a wiper on both sides of the corner radii (as the standard) but the protection chamfer is twisted from negative to positive or from positive to negative depending on the application.
It is available in grade CBN050C. The following considerations apply when selecting the appropriate geometry:
POSITIVE WIPER, WZP
- Reducing vibrations in weak setups
- Lower radial cutting forces
- Used where standard wiper cannot be used
NEGATIVE WIPER, WZN
- Longer tool life
- Reducing vibrations in stable setups
- Increasing compressive stresses
Crossbill TM Wiper
Until recently wiper designs on solid inserts were limited in their ability to machine towards a shoulder. This is due to the wiper design on one edge giving a reverse design on the opposite side of the corner radius.
The introduction of the Crossbill TM Wiper has addressed this issue.The unique patented design of the wiper allows for the utilisation of handed wiper technology on all cutting edges on a solid insert.
The Crossbill TM Wiper can be used for axially turning with all the usual benefits of wiper technology towards a shoulder and due to the design also machine a perfect radius.
The Crossbill TM Wiper inserts are available as TNGX1103XXS inserts with a range of nose radii in either right or left hand versions.
The standard wiper geometry has wiper edges on both sides of the corner radii with a standard chamfer following the grade.
It is used in general applications, machining in two directions with full wiper effectiveness, e.g. OD/ID turning and facing. It is available in grades CBN10, CBN050C, CBN100, CBN160C, CBN300 and CBN400C.
