M131W万能磨床经改装为塑料导轨后,工作台的低速平稳性大大改善,由于塑料导轨具有异物埋没的特性,能把铁屑、砂粒埋嵌入塑料内部,避免自身的磨损,可以防止拉毛和研伤对磨金属的表面,起到保护床身导轨的作用,对于当前为提高机床“完好率”、延长机床精度的保持周期,有着积极的意义。通过改装还可以提高机床的“易修性”,当聚四氟乙烯材料磨损后,可以更换,保持原尺寸链精度,便于维修和保养。因此,对于负荷均匀、工作条件较为理想的导轨副,可选用聚四氟乙烯(简称4F)对垫材料。
M131W universal grinder converted to plastic guide rail, the worktable greatly improved the smoothness of low speed, the plastic guide rail has the characteristics of foreign body buried, the iron filings can be buried in the plastic sand inside to avoid their own wear and tear can prevent hair and injury On the metal surface, play a role in protecting the bed rails, for the current machine to improve the “good rate” to extend the maintenance cycle of machine accuracy, has a positive meaning. Through the modification can also improve the machine’s “easy to repair”, when the PTFE material wear, you can replace, maintain the accuracy of the original size chain, easy to repair and maintenance. Therefore, for uniform load, the working conditions of the ideal rail pair, optional PTFE (referred to as 4F) on the pad material.
