CNC controls, axes and backgauge systems
How control platforms, axis packages and backgauge configurations change what a press brake can produce, and how to specify them.
What this topic covers
These guides are editorial selection references. Tables, worked examples and troubleshooting lists describe methods, not GWMT machine ratings, availability or certified performance.

Press Brake Back Gauge: Types, Axes, Calibration & Troubleshooting
The back gauge decides where every bend line lands on the sheet. This guide covers the mechanical construction of a back gauge, the manual, NC, CNC and servo types, what the X, R, Z, X1-X2 and R1-R2 axes each control, positioning accuracy and repeatability figures, a step-by-step calibration method, a fault troubleshooting table, a maintenance schedule by frequency, and how to choose a configuration for different production work.
Choosing 3, 4 or 6 Axes Around Your Parts
Look beyond the axis count: gauge position, bend sequence and setup frequency determine which movements need control.
Types of CNC Control Systems: Motion, Control Loop and Axes
The CNC control system is the brain of a press brake and directly determines bending accuracy, repeatability and efficiency. This guide explains the five core components of a CNC control system, classifies systems by motion type, control loop and axis count, sets out what Y1/Y2, X, R, Z1/Z2 and crowning compensation each do on a press brake, explains why closed-loop control is close to mandatory for bending, and gives a question order for specification along with a type comparison table.
