the coding controller is in signal connection with the camera and the coder;
a reset button, which is triggered by the code controller to start counting;
the coding alarm lamp is controlled by the coding controller to judge the diamond abrasive (2) L Real world Less than or equal to the distance L from the initial edge to the center of the diamond abrasive (2) 0 Controlling to light up and alarm when the number is 0.95;
L real world Is the actual distance from the edge to the center of the diamond abrasive (2); l (L) 0 Is the initial edge-to-center distance of the diamond abrasive (2).
8. The grinding system according to claim 7, wherein the reset button is activated and the encoder controller starts counting while taking a first picture of the double-sided diamond wheel with the end face of the quartz rod curved, extracting the initial edge-to-center distance L of the diamond abrasive (2) 0 ；
In the work of processing the end face of the quartz rod into an arc-shaped double-sided diamond grinding wheel, when the coding controller judges that the set revolution is reached according to the counting of the coder, the camera is started to acquire the abrasion photo of the diamond abrasive (2), and the actual distance L from the edge to the center of the diamond abrasive (2) is extracted in real time Real world 。
9. The grinding system of claim 8, wherein L is determined Real world Less than or equal to L 0 And (x 0.95), controlling the coding alarm lamp to alarm to remind the replacement of the double-sided diamond grinding wheel.
10. A grinding method, characterized in that the method is applied to the grinding system of claim 4, the method comprising:
obtaining the distance L from the initial edge to the center of the diamond abrasive (2) 0 And obtaining the actual edge-to-center distance L of the diamond abrasive (2) during operation Real world ；
L Real world Less than or equal to L 0 And when the torque reaches the torque limit value set by the servo motor (10-2), the servo motor (10-2) sends out a torque alarm signal, and the torque alarm component prompts the torque alarm signal.
