Roll regrinding quality of geometric factors and physical factors that affect the rubber cot honed work surface is distributed in the surface of the abrasive grinding wheel with rubber rollers for the relative movement of the surface composition of the score. Number of scoring unit area, the more uniform the smaller the score the more detailed surface roughness Ra value, this is the rubber roller honed during geometric factor. Cots soft materials, when poor heat tempered wheel easily clogged, coupled with abrasive cutting edge greater opening angle, usually 90 ° ~ 120 °, when the ground was a negative rake angle of the cutting edge in the roller surface swipe, engraved planning, cutting force and heat generated thereby enable the machined surface plastic deformation. Sharpen accuracy and surface plastic deformation will Cots roughness has important implications, this is tempered during Cots physical factors. In recent years, the textile industry associations to promote the use of cotton spinning surface does not handle the roller, according to statistical information on this cot representing Surface treatment Cots regrinding cycle extended twice, the use of Non-treatment Cots are spinning Spinners effective way to reduce the cost. A necessary condition for the use of the surface is not treated cots can be obtained directly after regrinding Cots ideal surface roughness. Practice has proved that the roller surface roughness honed honed during the affected geometrical factors and physical factors can be controlled by proper selection of the grinding parameters during operation.
