Hydraulic press brake AHK M 1540

NCprecision

Product description
The AHK M series is a modern, cost-effective NC alternative to CNC press brakes. It is designed for operators who prefer minimal CNC programming while maintaining modern safety standards. Back gauge positioning in X and R axes and depth stops in the cylinders can be set directly via the touchscreen, or bending sequences can be stored in the NC control for automatic execution. The series is suitable for repetitive production of parts with recurring materials and contours.

Highlights

• Stress-relieved welded steel construction
• Direct angle input for faster setup
• NC control with touch-screen HMI
• Motorized back gauge with X and R axes
• European-style segmented upper die

Machine frame and male die

• High-precision, stress-relieved welded steel frame with a rigid bending beam and hydraulic cylinders on both sides
• Large throat and narrow table provide free space for complex bending sequences

Hydraulics

• Hydraulic unit with 120 l reservoir placed in the top of the frame to save floor space and increase rigidity
• Torsion shaft connects depth stops of both cylinders for precise upper beam positioning

Front support arms

• Height-adjustable and robust support arms to assist handling of workpieces
• Stop ridge on the support surface for easier alignment

Bending tools

• Promecam tool mounts compatible with a wide range of bending tools
• Manual quick-action clamping to shorten tool change times
• Standard lower die with 4 V-segments to cover a broad spectrum of parts

Safety and productivity

• Safety concept based on current CE regulations
• Light curtains and optical safety systems protect the work area

Control

• Clear touchscreen HMI showing all functions in an organized layout
• Operator can enter desired bending angle directly for rapid setup
• NC control calculates required depth-stop position automatically using sheet thickness and stored tool data
• Three operating modes: Manual (motorized axis positioning), Semi-automatic (axes move to entered values), Automatic (execution of programmed bending sequences)
• Up to 500 program sets storable in internal memory; external backup and import via USB and network connection

Back gauge

• NC-controlled back gauge designed for high positional stability and machining precision
• Large preloaded ball screws and linear guides ensure low maintenance and rigidity
• Motorized R-axis for precise stop-height setup
• Lateral positioning of back gauge fingers on smooth-running linear guides
