Turret and multi-task machines

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.

• Improve the stability by applying a long design tool

holder and sleeve to increase the clamping length.

Recommended clamping length minimum 4 x dm

The Coromant Capto coupling can also be a solution on

a turret lathe or multi-task machine. This minimizes the

need for long sleeves and will result in a stable set-up

with additional quick-change benefits.
