Press Brake Back Gauge
Press Brake Back Gauge for sale
What is a Back gauge on a Press Brake? A Press Brake back gauge is a component used in a CNC press brake machine to correctly position and align workpieces for smooth bends. The CNC back gauge retrofit can ensure the bends with precision and consistent crossing of the X-axis ( length of a metal sheet). The back measuring instrument consists of a series of press brake back stop fingers and blocks, which can be adjusted to the desired position. the adjustable Press Brake Back Gauge makes for an easy set-up of repeatable bends.
The press brake can be equipped with two main CNC-controlled back gauge models. they are synonymous with robustness, accuracy, and speed. Movements are carried out through expandable and flexible digital servo drives. Motors and drivers are manufactured by Electric Works.
How does the press brake back gauge work?
The Press Brake Back Gauge retrofit makes for an easy set-up of repeatable bends. The CNC back gauge for press brake is composed of a beam, a screw, a motor, a finger, and a guide rail. The press brake Operators can adjust the position of the press brake back stops to determine the desired bend angle and length. When a piece of sheet metal is placed against the back gauge and the ram of the press brake descends, the back gauge for the press brake moves along one, two, or even several axes with the goal of positioning precisely where it needs to be for the forming process. the metal is bent at the specified location, guided by the back gauge’s positioning.
Types of back gauge for press brake
The Press brake is equipped with CNC back gauge fingers for accurate positioning on the workpiece. The type of press brake backstops and number of axes can be adapted to the type of process, part size, and number of working stations. and the precision of the workpiece determines the number of axes required by the press brake.
Standard 4 axis press brake configuration includes X, Y, and R axes. and is equipped with 2 manual backstops (Z-axis, press brake back gauge fingers).
X Stop finger back and forth moving axis
Y1 Left stop finger up and down moving axis (Depth )
Y2 Right stop finger up and down moving axis (Depth )
R1 left stop finger up and down moving axis (Hight )
R2 right stop finger up and down moving axis (Hight )
Z Motorized left stop finger left and right moving axis( press brake backstops can be moved crosswise to simplify positioning of parts with different lengths)
The press brake back gauge fingers determine the bending accuracy of the workpiece. The more complex the workpiece is, the more axes are required for the rear stopper. you can DIY press brake back gauge to increase productivity.
There will be a maximum of 6 shafts on the back gauge for press brake, which will have different variants.
Each press brake axis has an independent drive motor to ensure accurate positioning.
How to align back gauge on press brake?
Press Brake Back gauge calibration is mainly for maintaining the accuracy of the press brake and ensuring consistent results during the working time. The process includes checking and adjusting the various components of the back gauge to ensure functioning correctly and aligning properly. Aligning press brake back gauge has the following steps:
- Verify the accuracy of the back gauge
- Clean the back gauge and bed
- Adjust the position of the back gauge
- Test the accuracy of the back gauge after adjustment
