2-axis Gantry Robot

The 2-Axis Gantry Robot is a lightweight automated loading and unloading system for CNC lathes, drilling centres, and small machining centres. It adds a horizontal reach axis to the single-axis model's travel and lift. This forms a three-axis coordination system: X-axis travel, Y-axis front-back movement, and Z-axis reach. This gives more flexibility and a wider application range.

Compared to the single-axis version, the 2-Axis Gantry Robot has a reach function. This allows more complex loading and unloading. For example, picking a part from the tray, reaching horizontally into the machine spindle, clamping it, and then retracting. A single-axis robot cannot do this, but this system can do it easily.

Zhejiang Luban's 2-Axis Gantry Robot is widely used for automation on small and medium CNC machines. We have successful cases from hardware processing to auto parts, and from standard parts to shaped parts.

Some part loading is not as simple as "pick from point A and place at point B." For example, a shaft part must be picked from the tray, reached horizontally into the spindle, centred, and then clamped. Without a reach function, the robot cannot do this.

The 2-Axis Gantry Robot solves this with an extra reach axis. The robot picks the part from the tray. It then reaches horizontally to the spindle position. After precise alignment, it clamps the part. Then it retracts and waits for the next cycle. The whole motion is smooth and natural with no wasted movements. One customer processes long shaft parts. Before, their single-axis robot could not reach horizontally into the spindle, so they had to load manually. After switching to this system, everything from picking to clamping to unloading is automated. Efficiency improved by over 30%.

The robot uses three axes – horizontal travel, vertical lift, and horizontal reach. It picks parts from the storage position and moves to the machine door. The reach axis extends to put the part into the spindle. After clamping, the reach axis retracts. It waits for the machine to finish and then reaches in again to remove the finished part.

All three axes use servo motors with precision linear guides. Running is stable and repeat positioning is accurate. Speed can be adjusted to match the part and machine cycle. Starts and stops have soft buffering to avoid part damage. The control uses a Delta gantry system with an integrated touch screen teach pendant. The system connects to the machine through standard signals. It supports automatic picking, empty alarm, and fault stop.

The body uses a heavy steel structure. It is rigid and does not deform easily. The three axes use precision linear guides with servo motors. Running is stable with no shaking. The system is compact and has a small footprint. No workshop changes are needed. The storage position is standardised. Trays and limits can be changed quickly. By changing the gripper, it can fit shafts, discs, shaped parts, and standard small parts. The working temperature range is -10°C to 45°C. Safety features include a fence, emergency stop, sound and light alarms, and motion interlocks. If there is a stuck part, misalignment, or signal problem, it stops and alarms immediately.
