In CNC press brakes, the key to achieving repeatable, high-precision bends lies in accurate feedback. That’s where linear scales, also known as encoders, play a central role.
Mounted directly to the press brake frame and independent of hydraulic pressure, these devices measure the actual position of the ram (Y1/Y2 axes) in real time. This ensures that every movement reflects the exact intended stroke—regardless of machine wear, oil temperature, or material thickness variations.
🧠 Why Linear Scales Matter
Enable closed-loop control of ram position
Ensure ±0.01mm accuracy during bending
Detect deflection or misalignment instantly
Essential for synchronous cylinder control (especially with Y1/Y2)
