Teaching-Free Welding, Laser Cutting & Press Brakes
The 2026 Maichen range: teaching-free welding cells, 7-axis floor-rail and 7/8/9-axis cantilever workstations, robotic flame beveling, six-axis arms and positioners, eight fibre-laser cutting families from 1.5 to 120 kW, and CNC press brakes with robot bending cells. Specifications follow the 2026 catalogue.
Teaching-Free Intelligent Welding System
A 3D model or point cloud in, a welding path out — no point-by-point teaching
Vision and motion control come from one platform: the cell locates the part, extracts every seam, groups and sequences them, checks for collisions and generates the torch poses and process parameters. Operators load the part and press start; one person can run several cells.
| Specification | Value |
|---|---|
| Model input | STEP / STP / IFC with Tekla decomposition, 2D-to-3D conversion (about 2 minutes), or scan-based reverse modelling |
| Seam extraction | One click: all seams extracted, grouped, sequenced and collision-checked |
| Process library | Fillet, vertical, wrap-around, multi-pass and intermittent welds matched to plate thickness |
| Calibration | One-click TCP and hand-eye calibration, about 8 minutes to restore accuracy |
| Multi-robot | Master-slave task allocation and collision avoidance for large workpieces |
| Operation | No pendant teaching; one operator can run several cells |
Model source, part position and batch size determine the cell layout; the software and fixture package are confirmed per project.

Automated Bending Cells
Robot loading, flipping, angle measurement and stacking connect bending to cutting and welding
The robot takes the blank from the stack, the press brake runs the program, the flip fixture turns the part and the angle sensor checks the first piece. One operator can run several machines, and the cell can be linked to a laser cutting or welding cell.
