Press brake clamping system: quick selection and setup

System types and when to use each

Clamping mechanisms can be mechanical, hydraulic or pneumatic. Selection depends on change frequency, part length and accuracy targets. Mechanical offers simplicity and stiffness; hydraulic maximizes force and ergonomics; pneumatic excels in fast, repeatable releases with low effort.

Always verify opening height and total stack when adding adapters or intermediate blocks.

Installation, alignment and verification

1. Degrease seat and bearing faces; correct high spots with a straightedge.
2. Present the clamping unit and die; snug bolts in a cross pattern.
3. Sweep with a dial indicator every 200–300 mm: Δ ≤ 0.05–0.10 mm.
4. Center punch–V with gauges; apply shims only if required.
5. Record torque/crowning and L–C–R angles with a witness coupon.

Standardize the SOP per machine/shift to lower variability.
