Smart and upgrated, microcomputer control, PVC panel, menu-driven interface,LCD display,X axis adopts imported linear guide rail,,adding uniform buffer procedure, autolocking program, arbitrary positioning program, it runs much smooth and steady, the precision is much higher. Y axis uses imported double axis orbit, accessible wheel slider, set memory program, autolocked the height,run much more smooth and steady. Z axis uses American original numerical control tracker to automatic track the bump wall accurately and quickly. It solve the problem easily such as metope rough, the wall inclined, bump. It makes the construction much more convenient, safer, more effective.
