Gantry manipulator, the model is driven by a three-axis synchronous belt, and the large span X-axis is synchronized with the synchronous axis, and the Y-axis and z-axis are driven by common synchronous belt.The overall mechanism is cheap, eliminating the screw and servo motor structure, greatly reducing the cost, and the speed is also greatly improved.This model is transformed into step and iges general model download, please refer to!Also includes 3d original files, welcome to download!if you like,you can paypal for you to get this models or if you have any questions also you can email to me.
