[0087] It should be noted that during the aging test, the indicator light shows red when the CNC module to be tested fails, and shows green when it passes.

[0088] In some embodiments, Figure 2 As shown, the device also includes a Z-axis aging test mechanism connected to the fourth servo motor; the fourth servo motor and the Z-axis aging test mechanism constitute a Z-axis device;

[0089] The fourth servo motor here is also the Z-axis servo motor 401, which drives the mechanical movement of the Z-axis device 4. Through the control of the mechanical parts of the Z-axis device by the numerical control module, the movement status of each axis motor and the Z-axis device can be intuitively displayed. The change of the indicator light can be used to judge the indication of the numerical control module on the mechanical parts and the motor control operation status, thereby achieving the process of aging test of the numerical control module. It should be noted that the Z-axis device is an existing device, such as Figure 5 As shown, it specifically includes a Z-axis servo motor 401, a mounting plate 402, a slide rail assembly 405 and a ball screw 402. The fourth servo motor 401, that is, the Z-axis servo motor is arranged on the mounting plate 403.

The limit switch 407 is arranged on the mounting plate 403 outside the stroke controlled by the CNC module to be tested. Within the set time range, if the induction bracket 409 can trigger the limit switch 407, it proves that the CNC module to be tested has lost precise control over the Z-axis motor and aging occurs.

The actual working status of the X1-axis servo motor, X2-axis servo motor, Y-axis servo motor, Z-axis servo motor, and W-axis servo motor can be displayed on the display; within the set time, if the display prompts that one or several motors are working abnormally, it means that the CNC module 10 to be tested has aged within the set time and lost precise control of the motor, its performance is unreliable, and the quality is unqualified. The Z-axis servo motor performs mechanical motion feedback aging test status by controlling the Z-axis device. If the sensing bracket 409 triggers the limit switch 407, the indicator light 1 gives an indication. The test information includes but is not limited to the motor's speed and aging time; it means that the CNC module 10 to be tested has lost precise control of the motor, and the CNC module 10 to be tested has aged within the set time, its performance is unreliable, and the quality is unqualified; within the set time, if the limit switch 407 is not triggered and the display does not show that a motor is abnormal, it means that the performance of the CNC module 10 to be tested is stable and reliable, and the quality is qualified.
