失去山峰,离开山谷

高原珩磨通过轻轻地除去撕裂或折叠材料的微小峰来改善气缸壁面。球型珩磨工具通常用于产生这种理想的饰面。

闭合钻孔墙的表面将揭示许多微观峰和山谷。高原珩磨是一种通过轻轻地除去撕裂或折叠材料和增加轴承区域的微小峰来改善气缸壁面的过程。高原饰面是理想的,因为它允许润滑剂在剩余的山谷中收集,改善润滑控制和保留。它还延伸了诸如活塞环和密封件的部件的寿命,因为它们在初始断裂期间没有材料的峰。

生成一个高原完成的一个方法是使用落下帷幕l-style honing tools such as the Flex-Hone tools produced by Brush Research Manufacturing (Los Angeles, California). These tools have a number of round, abrasive stones or “globules” tethered to a shank by nylon filament. The globules effectively float in the cylinder, self-centering and self-aligning themselves to the bore and also self-compensating for wear. When a globule encounters a peak of material, it removes the peak through low-pressure abrasion. Thus, the surface Rp value (reduced peak height) decreases while the Rvk (reduced valley depth) increases, resulting in more effective lubricant retention.

滚珠式蹄适用于阀体,制动缸,主缸,枪械桶甚至乐器等部件中的孔和孔。Flex-Hone工具以直径为4至914毫米(0.16至36英寸)的牛油孔。它们有八种磨料类型,11种砂砾尺寸范围为20至800粒。

该公司建议使用每个应用程序的最短柄。磨料小球应良好地涂覆润滑剂并在进入之前旋转。此外,旋转应继续,直到工具完全从孔中取出。适当的工具转速范围为60和1,200转。小直径工具需要更高的速度。应保持每分钟120至180英寸的连续行程速度,每个汽缸的平均珩磨时间通常为15至20秒。
