内冷却砂轮工装研制

Development of a tooling for an inner cooling grinding wheel

由于磨削加工中过高的磨削温度,可采用内冷却砂轮磨削,将切削液直接浇注到磨削区内部,破坏了磨削区的封闭性,从根本上解决磨削温度高引起的工程实际问题。在普通磨床上采用内冷却砂轮磨削就必须提供内冷却砂轮工装,通过对砂轮内冷却总体方案、内冷却砂轮工装设计进行了研究,研制出了结构简单,性能可靠高的内冷却砂轮工装,将该工装用于M7130C平面磨床进行磨削加工,大大降低了磨削区温度,有效避免磨削烧伤,提高了磨削加工质量,效果良好。实验表明内冷却砂轮可加工某些难加工材料,扩大了磨床加工范围。

In order to solve too high grinding temperatures,inner cooling grinding wheels,which can break the closure of grinding area and solve practical engineering problems resulting from too high grinding temperature,are used in grinding.An inner cooling grinding wheel must be used in a plain grinder by tooling for grinding wheels,so it mainly studies how to deign and manufacture a tooling for an inner cooling grinding wheel,which has simple construction and reliable performance.Grinding experiment shows it can dramatically reduce cutting temperature and effectively avoid grinding burn,thus grinding quality is improved.
