16. Is the rubber roller grinding more reciprocating times better? Answer: The main purpose of grinding rubber roller is to make the surface of the rubber roller reach a certain precision, to meet the various geometrical dimensions of the spinning demand. How many times the grinding reciprocation directly affects the roughness of the surface of the rubber roller, then how many times As well? This depends on the material of the rubber roller itself,
the surface treatment method and the type of grinder. Consider the hardness of the hose: no matter what surface treatment is done, the rubber roller above 85 degrees should be ground two reciprocating, because the rubber roller of this hardness produces a slight jump when it contacts the grinding wheel, especially the rubber roller with high hardness and low elasticity Raindrop-shaped wear scars appear after grinding once, and must be reground once to eliminate the wear scars.
The two reciprocations need to be sharpened below 75 degrees, because the rubber roller with low hardness is easy to squeeze and deform during grinding. Only through regrind can the deformed part be eliminated, so as to ensure that the surface roughness of the rubber roller meets the requirements.
