specific Embodiment approach 1

[0022] Specific embodiment 1: This embodiment processes the diamond tool according to the following steps: 1. After the air vibration isolation pad is inflated, adjust the balance state of the sharpening machine to keep it level; Control the working surface finish of the grinding disc to ≤0.8, and then coat diamond abrasive grains with a maximum diameter of 0.1 μm; 3. Use a high-precision dynamic balancer to perform fine dynamic balance on the spindle system of the grinding machine at a speed of 2800r / min, and control the spindle at 2800r The radial rotation accuracy is less than 0.05 μm and the axial rotation accuracy is less than 0.1 μm at the working speed per minute; 4. After the grinding disc is coated with diamond abrasive grains with a maximum diameter of 0.1 μm, the pre-grinding work is performed first, and then the diamond tool is sharpened. The specific operation steps are: install the diamond tool, adjust the level of the tool body fixture; turn on the air source, tu...
