Running-in machine

The invention relates to the technical field of machine tool detection, and particularly discloses a running-in machine which comprises a box type machine table, an operation box is arranged on the table top of the box type machine table, a PLC used for controlling the whole machine is arranged in the operation box, and an operation panel used for operation control is installed on the main view face of the operation box. A motor driver is arranged in the box body machine table, and a brake resistor used for consuming energy generated by sudden stop of the machine tool motor and a transformer used for supplying power to the machine tool motor in a voltage transformation mode are arranged on the outer side of the box body machine table. Through cooperative use of the PLC, the motor driver, the brake resistor and the transformer, the running-in test of each motor of the machine tool can be realized, and in addition, the matching condition of the screw rod and the slide rail in the machine tool can be tested, so
