Abstract

镍-钛合金牙医铰刀的制造方法，所述牙医铰刀是由一种圆柱金属坯制造的，该坯在旋转矽轮前面以进料速度VA移功，砂轮的不同直径的盘决定了材料的切削线性速度VL，其特征在于，这些参数如下：
-VL高于91440厘米/分钟，
-VA低于7.62厘米/分钟。
本发明还有一个目的是如此得到的牙医铰刀。

Description

镍-钛合金牙医铰刀的制造方法
本发明涉及一种镍-钛合金(称之NITI)牙医铰刀的制造方法。
这些牙医铰刀主要是用一种金属圆柱毛坯制造的，它们通常由至少40％的钛组成，尽管这种比例对于使用这种方法来说不是关键。
金属毛坯棒在旋转的砂轮前以进料速度VA移动，砂轮的不同直径的盘决定了旋转砂轮切削毛坯材料的线性速度VL。
另外一个重要参数是由砂轮颗粒尺寸DG决定的，这通常是在金钢砂的情况下。
在US5464362专利中已经描述了这种类型的方法，其中要求保护和所描述的值如下：
-VA为7.62-20.32厘米/分钟，
-DG高于200粒。
出乎意料地并与现有方法中存在的一些最佳条件的情况完全矛盾的情况已表明，相反的运行条件给出至少相同的结果。
因此，本发明的目的是制造镍-钛合金牙医铰刀，所述的牙医铰刀是由一种圆柱金属坯制造的，该坯在旋转砂轮前面以进料速度VA移动，砂轮的不同直径的盘决定了材料的切削线性速度VL，其特征在于，这些参数如下：
-VL高于91440厘米/分钟，
-VA低于7.62厘米/分钟。
有利地，砂轮颗粒的粒度大于46μ。
根据一种优选的实施方式，该砂轮是一种金钢钻砂轮。
最佳地，所确定的参数如下：
-VL＝2213米/分钟
-VA＝3.2厘米/分钟。
当然，应当理解，实施该方法的任何其它因素都应与现有的方法相同。
