Press Brake Back Gauge Axis

BACK GAUGE SYSTEMS

The correct back gauge for the application can have a substantial positive influence on production part volume and accuracy. The more intricate the parts, typically the more axes on the back gauge you should have. Volume of parts needs to be considered also. A smart, experienced brake press operator can bend, form and produce some very intricate parts without even a single axis back gauge. However, the more time it takes to form the correct part, the more costs you have in the part. So the best scenario would be to have an experienced operator with the correct back gauge system that will magnify their skills. But in today’s market, smart, experienced Press Brake operators are getting hard to find. So the correct back gauge for the application will decrease costs per part by helping to make a good press operator, a great one. The less experience an operator is the more axes you should have. Also, experienced operators know the benefit of correct back gauge for applications. JMT is here to consult with you on your application requirements.

1 AXIS BACK GAUGE (X)

X Axis: Motorized, CNC Controlled, R Axis: Manually height adjustable finger block Fingers depth (X axis) is calculated by CNC controller. Retraction is also a standard feature to eliminate collision. Back gauge fingers are easily adjusted on the ball rail linear guides and can be fixed in place.

The single axis back gauge comes with a Motorized, CNC controlled X axis which controls the finger depth (flange depth). Programmable Re?traction is also a standard feature to eliminate any possible collision. The back gauge fingers are easily adjusted on the ball rail linear guides and can be fixed in place. Back gauge fingers also have a simple micrometer adjustment for calibration. Also fingers can be moved manually and fixed in desired place. R1, R2, Z1, Z2 axes are adjusted manually and can be fixed in place.

2 AXIS BACK GAUGE (X,R)

Our press brakes are equipped with CNC 1 axis back gauge. Optionally we offer a 2 Axis CNC back gauge (X-R). Fast and precise 2-axis CNC controlled back gauge that automatically adjusts the X (depth) and R (height) axes to ensure your material is always positioned accurately, resulting in higher quality finished parts.

Axes movements are driven by AC motors and drivers. Using the best components, such as THK (Japanese) ball screws, our back gauge movements are fast and precise, with X-axis speeds up to 600 IPM and high accuracy.

Finger blocks are mounted on linear guides to be more rigid and accurate, which ensures accurate part positioning over a longer period of time.

Utilizing top quality components adds to the longevity of your machine.

4 AXIS BACK GAUGE (X,R,Z1,Z2)

Our ADS and AD-Servo press brakes are equipped with a fast and precise 2-axis CNC controlled back gauge. Optionally we offer a 4 Axis CNC back gauge (X-R-Z1-Z2) With this back gauge system the CNC press brake control calculates the depth, height and width of the back gauge fingers. This back gauge features superior accuracy and speed. This translates to more correct parts at the end of the day.

This is accomplished with high quality components such as Siemens Servo Motors and drives. Also THK Ball Screws and Rexroth Linear rails. X Axis speeds are programmable to 1200 IPM with accuracy to .0004”. Finger Blocks are located on linear hardened precision ground linear rails. This will ensure accuracy for many years to come. Rails are built so that parallelism between Back gauge fingers and tip of the punch are easily aligned.

5 AXIS BACK GAUGE (X1,X2,R,Z1,Z2)

Our Electrohydraulic Servo press brake and high tonnage series press brakes are optionally equipped with CNC 5 axis back gauge. This option, allows faster, more accurate positioning of asymmetrical work pieces. Slanted bend lines allows for +- 5” of travel (Total 10”).

This is accomplished with high quality components such as Siemens Servo Motors and drives. Also Taiwan Hiwin Ball Screws and Rexroth Linear rails. X Axis speeds are programmable to 90 mm per min with accuracy to .0002 mm.

Finger Blocks are located on linear hardened precision ground linear rails. This will ensure accuracy for many years to come. Rails are built so that parallelism between Back gauge fingers and tip of the punch are easily aligned.

6 AXIS BACK GAUGE (X1,X2,R1,R2,Z1,Z2)

The 6-axis back gauge offers you the highest degree of flexibility with highest production speeds. All 6 axis can be positioned independently of each other. Fingers can be independently located three dimension (X,R,Z) in the space. Control unit calculate finger positions on each axis. Stable finger position for asymmetrical work pieces, no setup times for back gauge adjustment.
