Hydraulic press brake C series

CNC8-axisrobotic

Overview
WEIYA WyBend CNC press brake machines combine Delem DA controllers, heavy-duty welded steel frames, synchronized hydraulic/servo drives and hydraulic crowning to deliver consistent bending accuracy across full production runs.

Key features

• Heavy-duty welded steel frame with annealing stress relief for minimal deformation under high tonnage loads.
• Multi-axis CNC control (manages X / Y1 / Y2 / R / Z, up to 8+1 axes) with graphical programming, automatic angle calculation and real-time feedback.
• Synchronized dual high-performance actuators (hydraulic or torque-controlled servo) for smooth, repeatable ram motion.
• CNC hydraulic crowning with adaptive compensation to maintain parallelism and uniform bending angles over long/thick sheets.
• Precision multi-axis backgauge (X / R / Z axes) with ball screw + linear guide transmission for accurate positioning and reduced scrap.
• Optional safety guarding & light curtains to meet IEC 61496 and operator-protection requirements.

Applications & Performance
WyBend C series is engineered for sheet metal processing across industries such as automotive, shipbuilding, construction and furniture. Models can bend carbon steel and stainless steel at thicknesses dependent on grade and bending length (examples: carbon steel up to 20 mm for WyBend40040 model; stainless up to 18 mm). Variable-displacement pumps and efficient servo drives lower energy consumption (average power 11–30 kW depending on model and workload).

Service, support & lifecycle

• Support offerings include eco-compliant oil disposal, hydraulic maintenance (oil analysis, seal replacement, pressure calibration), foundation engineering for heavy models and a 24-month warranty covering hydraulic cylinders and CNC systems.
• Recommended maintenance: monthly checks of oil level and filters; quarterly hydraulic connection and seal inspections; annual full-system inspection, oil analysis and calibration.
• Standard electrical supply example: 380V, 3-phase, 50Hz (configurable for other local standards).
