Abstract
Description
Claims (10)
- 材料のバーストックをネジ加工機に装填し、該バーストックの少なくとも一部にカッターヘッドでネジを切削加工し、該バーストック及びカッターヘッドに制御された振動効果を与えることにより該切削加工中にネジに複数の刻面を形成する工程を含み、該刻面はネジの少なくとも一部についてネジ深さが変化する複数の頂部及び谷部によって形成されることを特徴とする、矯正ネジの製造方法。
- 前記制御された振動効果は、ネジ加工機において、バーストックに対して所定のクリアランスを有するガイドブッシュを選択することによって実行され、このクリアランスが前記制御された振動効果を生じさせるための所望のハーモニックレベルを与えることを特徴とする、請求項1記載の方法。
- 前記切削加工はさらに、公知の制御振動効果を用いて所望の再現可能な多面デザインを形成するように設計された円形カッターツールを選択することを含む、請求項1記載の方法。
- 前記切削加工はバーストックの回りに少なくとも2つの寸法に実行される、請求項3記載の方法。
- ガイドコレットとバーストックの間のクリアランスを0.0002〜0.005インチ(0.005〜0.127mm)の範囲内に選定することによって前記所望のハーモニックレベルを与える、請求項2記載の方法。
- バーストックをバーフィーダーに装填し、該装填バーストックに制御されたミリング効果を与えるように設計された所望のクリアランス関連ハーモニックレベルを有するガイドブッシュを選択し、所望のネジ形状にあらかじめ設計された円形ネジ加工ツールを選択して設置し、該円形ネジ加工ツールを用いて前記所望のハーモニックレベルでバーストックを切削して、ガイドブッシュの制御されたミリング効果の下でバーストックの少なくとも一部に多面ネジを刻設形成する工程を含むことを特徴とする、矯正ネジの製造方法。
- 前記制御ミリング効果は前記クリアランス関連ハーモニックレベルによって装填バーストックに生じる制御振動効果である、請求項6記載の方法。
- 軸と、この軸の少なくとも一部に刻設されたネジ部と、このネジ部の少なくとも一部にこれを横切って延長するように形成された複数の刻面とを有し、該刻面はネジ深さを変化させる複数の頂部及び谷部を有し、骨とネジ切りされた軸との間の摩擦を減少させることによってネジを骨にネジ込んでいくときに必要とされるトルクを低下させると共に、骨への挿入後に緩みが生じることを防止するように働くことを特徴とする、矯正ネジ。
- 頂部と谷部との間が平面とされている、請求項10記載の矯正ネジ。
- 頂部と谷部との間が凹面とされている、請求項10記載の矯正ネジ。
