细纱机上的罗拉长期以来由于淘槽光洁度差,表面存在毛刺及快口,致使运转时积聚棉花,影响纺织质量和罗拉的使用寿命。83年初,纺织部指示细纱机要创优等品。因此,必须解决罗拉表面的毛刺和快口以及提高罗拉表面光洁度等质量问题。根据罗拉的特性,我们采用化学抛光法来解决这问题。由于罗拉齿面外圆公差较紧(Φ25-0.052mm),且要求表面不受腐蚀和损伤。同时在化学抛光后用手
Roller on the spinning frame has long been due to poor finish of the Amoy trough, burrs and fast mouth on the surface, resulting in the accumulation of cotton during operation, affecting the quality of the textile and the service life of roller. In the beginning of 83, the textile department instructed the spinning machine to create excellent products. Therefore, it is necessary to solve the quality problems of the burr and quick mouth of the roller and the improvement of the surface finish of the roller. According to the characteristics of roller, we use the chemical polishing method to solve this problem. Due to the tight tolerance of the roller flanks (Φ25-0.052mm), the surfaces are not subject to corrosion and damage. At the same time after chemical polishing by hand
