21st century ,the textile industry gets into a high-speed and fine spinning era, tianyi precision ceramic(JJTY) as a brilliant leader of ceramic friction disk has developed tianruan high-grade ceramic friction disk (PYRT),becomes a brilliant leader of high-grade ceramic friction disk again by technical accumulation of recent twenty years, assiduous tacking of key problems about four years, over all transformation and renewal of machining equipments, whole perfecting and improvement of checking are examining measures, a big increase of technical force.

　　The high-speed and fine spinning is a general title of high-speed spinning and fine spinning, for the sake of satisfying the needs of high-speed spinning users, tianyi precision ceramic company has developed“tianruan high-speed ceramic friction disk(GSRT)”; for the sake of satisfying the needs of fine spinning users, tianyi precision ceramic company has developed “PU ceramic friction disk(PURT)”. Two series i.e. high-speed ceramic friction disk(GSRT) and PU ceramic friction disk(PURT) have over 120 specifications of tianruan high-grade ceramic friction disk(TYRT).
