The accuracy of the bending process is determined by the accuracy along the Tx and Ty axis, i.e., vertical and
horizontal tolerances in the press brake and tooling. The Ty axis value is decisive in determining the
parallelism between punches and dies. The Ty axis adjustment, which is
normally incorporated into our Crowning Systems and Bottom Tool Holders, is able to easily
and effectively correct accumulated machine tolerance across the length
of the whole machine. This is extremely important as far as quality is
concerned, but is also a factor that can help to significantly extend
the life span of press brakes.
Compensation in Tx
The Tx axis value
relates to the location of the tooling center position in relation to
the back
gauge, which is critical for producing accurate flange lengths. The Tx
axis adjustment
has been included in all Crowning systems and Bottom Tool Holders
suitable for press brakes
featuring the UPB (Universal Press Brake) hole pattern. Alignment
corrections along the Tx axis are normally only used during the
installation process.
