The invention provides an experiment table for preparing a diamond electroplated wire saw. The experiment table comprises an electroplating tank, a machine frame, a horizontal movement mechanism and across beam, wherein the electroplating tank is arranged below the machine frame, the cross beam is arranged on the machine frame and is positioned above the electroplating tank, and the horizontal movement mechanism is arranged on the cross beam; and the horizontal movement mechanism comprises a horizontal reciprocating moving mechanism and a saw wire support, the saw wire support is arranged onthe cross beam and is connected with the horizontal reciprocating moving mechanism, the horizontal reciprocating moving mechanism is arranged on the cross beam, and the two ends of the saw wire support are provided with a tensioning force adjusting mechanism and a tensioning force detecting mechanism correspondingly. The experiment table has the advantages of being simple in structure, easy to install and adjust, convenient to test and operate, and capable of realizing the saw wire electroplating experiment under different wire feeding speeds, different tensioning force and other different process parameters; and the experiment table can be used for exploring optimal original wire movement speed, tensioning force and other process parameters when a diamond-electroplated saw wire is prepared by steel wires with different diameters and materials, and can be used for providing relevant experimental basis and technical support.
