Used Press Brakes for Sale 200

Press brakes are present in virtually every sheet metal fabrication shop, performing the bending operations that transform flat laser-cut or punched blanks into the three-dimensional components that constitute most fabricated metal products — brackets, enclosures, channels, panels, and structural sections.

Tonnage and bending length are the primary specifications. Tonnage determines the maximum bending force available — affected by material type, thickness, bend length, and die opening. A general guideline is approximately 8 tonnes per metre for 1mm mild steel in a V-die, scaling proportionally with thickness squared. Bending length — typically 2,000mm to 4,000mm on production machines — determines the maximum part dimension perpendicular to the bend line.

CNC backgauge systems position the workpiece accurately for each bend in the sequence. Two-axis backgauges (X and R) handle most work. Six-axis systems (X, R, Z1, Z2, X-delta, R-delta) position and tilt the fingers for complex bend sequences with varying flange heights and angles.

Crowning — compensation for bed deflection under load — ensures consistent bend angles across the full bending length. Manual crowning uses shimmed wedges. CNC crowning adjusts automatically based on the programmed tonnage and material. Adaptive crowning measures the actual angle during bending and corrects in real time.

Drive technology affects precision, speed, and operating cost. Conventional hydraulic presses suit general fabrication. Servo-hydraulic drives reduce energy consumption. Servo-electric drives eliminate hydraulic oil entirely for the cleanest, most efficient operation.

Tooling compatibility determines which punch and die profiles can be used. European-style precision-ground tooling with standardised clamping systems is most common on modern CNC press brakes.

When evaluating used press brakes on Exapro, verify ram repeatability across the full bending length, check cylinder condition for drift and synchronisation, test CNC backgauge positioning accuracy, verify crowning system effectiveness under rated tonnage, and confirm tooling clamping system compatibility with your existing or planned tooling inventory.
