Step 2: Electroplating: Diamond abrasive is electroplated onto the saw blade substrate. After electroplating for 3 hours, a high-efficiency cooling diamond saw blade is obtained, wherein the embedding rate of diamond abrasive in the saw blade substrate is 65-70%.

The specific working process of this analysis module is as follows: Step 1: Obtain the diamond ball milling performance value ZQJ for each monitoring sub-region of the acquisition module. i Through formula The total performance value ZQJ of the first diamond ball milling was calculated. Through formula The total performance value ZQJC of the second diamond ball mill was calculated. Step 2: Substitute the obtained first diamond ball milling performance value ZQJ and second diamond ball milling performance value ZQJC into the formula. In the calculation, the diamond ball milling coefficient XQ is obtained; where b1 and b2 are both proportionality coefficients, with b1 taking the value of 2.03 and b2 taking the value of 1.36; Step 3: Compare the obtained diamond ball wear coefficient XQ with the diamond ball wear coefficient threshold; If the diamond ball milling coefficient XQ is greater than the diamond ball milling coefficient threshold, a diamond ball milling failure signal is generated.

[0007] As a further aspect of the present invention, the specific working process of the acquisition module is as follows: Step 1: Obtain real-time images of the diamond ball milling process, divide the real-time images into i equal monitoring sub-regions, and obtain the R-angle and volume of the diamond in each monitoring sub-region, and label them as JJ and VJ respectively; Step 2: Using the formula The diamond ball milling performance value ZQJ for each monitoring sub-region was calculated. i .

[0008] As a further aspect of the present invention, the specific working process of the fault module is as follows: Step 1: Obtain the diamond ball milling coefficient XQ from the analysis module, and obtain the current ball milling time Tq, using the formula... The ball milling ratio coefficient XB is calculated. Step 2: Compare the obtained ball milling ratio coefficient XB with the ball milling ratio coefficient threshold; If the ball milling ratio coefficient XB is greater than the ball milling ratio coefficient threshold, a continue ball milling signal is generated.

The saw blade base has a thickness greater in the middle than in the arc section, exhibiting a structure that is thicker in the middle and thinner at the ends, while the diamond abrasive has an angular structure. The manufacturing process of this high-efficiency cooling diamond saw blade includes the following steps: Step 1: Preparing diamond abrasive: Select block or plate-shaped diamonds, add the diamonds and stainless steel balls with a diameter of 1 mm into a ball mill and ball mill for 20-30 hours to obtain diamonds with angular structures. Step 2: Electroplating: Diamond abrasive was electroplated onto the saw blade substrate. After 3 hours of electroplating, a high-efficiency cooling diamond saw blade was obtained.
