Analysis and introduction of diamond grinding wheel grinding machine usage tips

Superhard grinding wheel grinding, especially high-speed grinding, requires good processing stability, low vibration and high linear speed. Therefore, there are higher requirements for grinding machines:

(1) The diamond grinding wheel spindle rotation accuracy should be high.

(2) The grinder rigidity should be good, generally required to be about 50% higher than ordinary grinders, usually should not be less than 100N/μm.

(3) The grinding machine feed system should have high accuracy, 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 to ensure the dimensional accuracy, geometric shape accuracy and           surface roughness of the grinding.

(4) The moving parts of the grinder, such as the head frame spindle and bearing parts, the feed motion guide parts, etc., should have reliable seals to prevent the entry       of superhard abrasives and accelerate the wear of the machine parts.

(5) There should be a relatively complete grinding fluid filtration and supply system, and the filtration accuracy should be less than 0.5μm.

(6) Each part of the grinder should have corresponding vibration prevention and isolation measures, and the diamond grinding wheel should be finely balanced.
