LANHAO LHA-3200A
CNC Panel Bender — Product Description
Zero Tool Changeover. Flexible Production. Intelligent Bending.
01 Product Overview
The LHA-3200A is Lanhao's CNC panel bender, built for manufacturers who need to move between different sheet metal jobs without manual tooling changeovers. It automatically assembles tooling segments to match each workpiece's required length, so production keeps moving as part specifications change.
Combined with intelligent CNC programming, automatic bending path optimization, and closed-loop control, the LHA-3200A is built for high-mix sheet metal production, where flexibility, efficiency, and consistent quality matter most.
02 Key Features
▸ Zero Manual Tool Changeover — Tooling segments assemble automatically to match each workpiece's required length, removing manual tool swaps and cutting setup time between jobs.
▸ Self-Developed CNC Control — An in-house CNC system supports intelligent programming, intuitive operation, and automatic bending path optimization across different workpiece geometries.
▸ Multi-Axis Servo Precision — Multi-axis servo control, a high-rigidity mechanical structure, and closed-loop accuracy control combine for precise positioning and stable, repeatable bending.
▸ Flexible High-Mix Production — Manufacturers can switch between different part specifications efficiently, without repeated manual tooling adjustments.
▸ Reduced Labor Dependency — Automation reduces manual intervention and supports more efficient continuous production.
03 Applications
The LHA-3200A processes cold rolled steel, galvanized steel, stainless steel, and aluminum, and is suitable for a broad range of sheet metal fabrication work, including:
▸ Electrical Cabinets
▸ 
▸ Storage Cabinets
▸ 
▸ HVAC Equipment
▸ 
▸ Kitchen Appliances
▸ 
It supports both customized parts and batch production.
04 Production & Automation
The LHA-3200A supports the full bending process with minimal manual intervention:
Job Programming → Automatic Tooling Preparation → Sheet Metal Forming → Repeatable Production
Its flexible configuration suits both customized production and batch manufacturing, especially where product variety is high and setup time needs to be minimized. It can also integrate with automatic loading and unloading systems, robotic handling, and intelligent production lines, extending from standalone CNC bending into a more connected, automated production environment:
▸ Automatic Loading & Unloading Integration
▸ Robotic Handling Integration
▸ Intelligent Production Line Integration
▸ Suitable for Industry 4.0 Manufacturing
