LANHAO
LHA-A SERIES CNC PANEL BENDER
Zero tool changeover, from single parts to full production runs
01 Product Overview
The LHA-A series is Lanhao’s CNC panel bender line, built around one core idea: getting rid of tool changeovers entirely. It pairs a self-developed CNC control system with automatic tooling change and high-precision servo bending, aimed at shops that need to move between different jobs without losing time to setup.
Most panel benders still need a tool change between jobs, whether it's done manually or by an automatic tool changer. The LHA-A series works differently: its automatic tooling change assembles tooling segments to the exact length each workpiece calls for, so production keeps moving as part specifications change.
02 Product Features
No Manual Tooling Change Required
The LHA-A series uses automatic tooling change: tooling segments assemble to match the length of each workpiece, with no manual tool swap in between. This removes a major source of downtime and keeps output consistent across multi-product runs.
Intelligent CNC Control System
A self-developed CNC control system supports intuitive operation, intelligent programming, and optimized bending paths. Precise multi-axis control keeps bending performance stable and production repeatable.
Flexible Sheet Metal Processing
The LHA-A series processes cold rolled steel, galvanized steel, stainless steel, and aluminum. It's widely used in electrical cabinets, storage cabinets, HVAC equipment, kitchen appliances, medical equipment, and other sheet metal fabrication industries.
High-Precision Bending Performance
Servo control technology and a high-rigidity mechanical structure deliver accurate positioning and stable bending. Closed-loop control keeps bending angles and product quality consistent throughout continuous production.
Automated Manufacturing Integration
The LHA-A series connects with automatic loading and unloading systems, robotic handling, and intelligent production lines, extending into a fuller automated setup that spans everything from prototyping to mass production.
03 Main Functions
▸ Automatic tooling change matches job length — no manual changeover between jobs
▸ CNC intelligent programming and operation
▸ Multi-axis servo control system
▸ Automatic bending path optimization
▸ High-speed sheet metal forming
▸ Closed-loop bending accuracy control
▸ Support for automated production line integration
▸ Suited to both customized and batch production
04 Competitive Advantages
Compared with traditional press brakes, the LHA-A series delivers higher automation, shorter setup time, and greater production flexibility. Because no tooling change is needed between jobs, manufacturers can move between different products without manual tooling adjustments — a clear fit for diversified, high-mix production.
The LHA-A series reduces labor dependency, raises production efficiency, and keeps product quality consistent. Its intelligent CNC control, flexible processing capability, and easy integration with automated systems make it a natural fit for manufacturers moving toward Industry 4.0.
