3040 Y axis extension base table for CNC Machine 3020Evo The extension base expands the y-axis of 3020Evo, and increases the Y-axis travel to 300mm/11.81". You can get a larger operating space and engraving area. The extension base is equipped with a 300*400*8mm aluminum plate, in which 6*8 M5 screw holes are neatly distributed, and the distance between the screw holes is 45mm. The surface of the anodized aluminum plate has better gloss and wear resistance. (Due to the transportation process, each position of the aluminum plate table is not absolutely horizontal) The Y-axis dual linear guide rails of the extension base, combined with the 3020Evo original X&Z-axis dual linear guide rails, have completely improved the accuracy of each axis of the machine. The entire extended base weighs 16lb, which greatly improves the stability of the machine, makes it easier to engrave various materials, and reduces the repeatability of operations The extension base is pre-installed as a whole and can be used immediately upon receipt.
