The standard heavy duty X-axis back gauge is DNC controlled and mounts on the rear of the table. One or two precision ball-screw spindles, actuated by an AC servo-motor and mounted on twin linear bearings, drive the back gauge.

With the twin linear bearing system, each robust linear carriage is mounted near the side frames to allow a reverse bend to fold down behind the machine. This is an important feature which is not usually available on single ball-screw centrally mounted back gauges.

The standard X-axis back gauge has two probes, both of which are manually adjustable in height (R) and can be manually positioned anywhere along the length (Z) of the back gauge bar.

Additional powered axes options include X1 & X2, R, R1 & R2, Z, Z1 & Z2.

• Y1-Y2 axes, (standard) for depth adjustment of the ram
• V-axis, for crowning of the bottom beam (Anti Deflection System)
• X-axis single or twin ball-screw, for positioning of the back gauge (also available in X1-X2 configurations)
• R-axis, for height adjustment of the back gauge (also available in R1-R2 configurations)
• Z for lateral adjustment of probes (also available in Z1-Z2 configuration
