Precision Gantry Manipulator

The Precision Gantry Manipulator is an automated loading and unloading system made for high-precision CNC machining. It fits precision CNC lathes, high-speed drilling centres, and precision machining centres. It uses a high-strength precision gantry structure with a full servo closed-loop control system. Its main features are high repeat positioning accuracy, smooth running, and high stability.

This system is mainly used for high-precision parts like aerospace parts, medical devices, 3C precision parts, and micro hardware. Its positioning accuracy and running stability are far better than standard gantry robots. It can match the needs of precision CNC machines and run 24-hour unmanned precision processing.

Zhejiang Luban has many years of experience with precision gantries. We have supplied systems to Fortune 500 companies like Shandong Energy and General Motors. Our products' accuracy and stability have been strictly verified. We hold many patents. Our R&D team continuously works on precision automation to ensure every system meets high-end manufacturing standards.

Precision parts processing requires very high loading accuracy. If the pick position is off by even a fraction of a millimetre, the part may not be clamped correctly. The finished product may be out of tolerance. If the robot shakes, the part surface may be scratched and scrapped.

The Precision Gantry Manipulator solves these problems with a rigid structure and closed-loop control. The whole body uses thick sections that have been stress-relieved. It is rigid and has excellent vibration resistance. During high-speed running and direction changes, there is no shaking or resonance. The built-in closed-loop feedback control removes drive gaps and positioning errors. Repeat positioning accuracy is very high. One medical device customer told us that after using this system, their part clamping consistency improved greatly. Their yield rate went from 92% to over 98%. This one change saved them tens of thousands of yuan in scrap costs each year.

The robot uses three-axis servo coordination – horizontal travel, vertical lift, and horizontal reach. It takes parts from the multi-layer magazine and moves precisely to the machine door to wait. When the machine finishes and opens the door, the robot removes the finished part and loads the new one with precision alignment. The whole motion is smooth and gentle, with no impact on precision parts.

The control uses a Delta gantry system with an integrated touch screen teach pendant. Speed, grip force, and start/stop timing can all be finely adjusted. For thin-wall, micro, and easily damaged parts, it can grip softly and move smoothly. The system connects to the machine through standard signals. It supports automatic picking, empty alarm, and fault stop.

The body uses thick sections that have been stress-relieved. The structure is stable and does not deform. The three axes use precision racks and high-accuracy linear guides with imported servo motors. Drive gaps are eliminated. The robot repeat positioning accuracy is within 0.05 mm. The multi-layer magazine uses a modular design. Layer spacing can be adjusted for different part sizes. The working temperature range is -10°C to 45°C. The electrical system has anti-interference shielding. It resists high-frequency equipment and voltage fluctuations in the workshop. There is no parameter drift with long-term running. Safety features include dual hardware and software protection: a fence, emergency stop, collision detection, overload protection, and misalignment alarms. If it detects even a small interference, load problem, or positioning error, it stops and alarms immediately.
