Clamping of Silent Tools bars
Due to the design of the turret in a CNC lathe or the flexibility of
a multi-task machine, the rigidity is usually reduced. Small turret
widths reduce the ratio between the clamping length and the bar
diameter on larger cylindrical boring bars and consequently reduce
the set-up stability.
The Coromant Capto coupling can also be a solution on a turret
lathe machine. This minimizes the need for long sleeves and will
result in a stable set-up with additional quick-change benefits.
The importance of correct clamping can not be underestimated. The pictures
show surface finish with 1) incorrect clamping and 2) split holder clamping.
