Grinding with superhard grinding wheel, especially high-speed grinding, requires good machining stability, low vibration and high linear speed. Therefore, there is a requirement for grinder:
(1) The rotation accuracy of diamond grinding wheel spindle should be high.
(2) The rigidity of grinding machine is better. Generally, it is required to be about 50% higher than that of ordinary grinding machine, and it should not be less than 100N/ μ The order of magnitude of M.
(3) The accuracy of the grinding machine feed system should be high, the feed speed should be uniform and correct, the minimum longitudinal feed speed should reach 0.3m/min, and the transverse feed (cutting depth) should reach 0.001 ~ 0.002mm/single stroke, so as to ensure the dimensional accuracy, geometric shape accuracy and surface roughness of grinding.
(4) All moving parts of the grinder, such as the main shaft and bearing part of the head frame and the feed moving guide rail, shall be reliably sealed to prevent the entry of superhard abrasive and accelerate the wear of the parts.
(5) There should be a relatively perfect grinding fluid filtration and supply system, and the filtration accuracy should be less than 0.5 μ m。
(6) All parts of the grinder shall be provided with corresponding vibration prevention and isolation measures, and the diamond grinding wheel shall be subject to fine dynamic balance.
