Description
前記直線送り軸の何れとも平行ではなく、かつ前記主軸の回転軸線と交差する傾斜軸線周りに前記主軸頭を回転させる回転送り軸装置と、前記主軸の回転軸線と前記傾斜軸線との交点が前記主軸のテーパ穴に装着した工具ホルダのゲージライン上または前記主軸の先端面内に配置されるように前記主軸頭を回転可能に支持する主軸頭ベースとを具備する工作機械が提供される。
図1〜図3を参照すると、本発明の好ましい実施形態による工作機械100は、NC装置(図示せず)によって制御される5軸のマシニングセンタを構成しており、工場の床面に設置された基台としてのベッド102、ベッド102の前方部分の上面で前後方向またはZ軸方向に移動可能に設けられワーク(図示せず)を固定したパレットPを着脱可能に取り付けるテーブル122、ベッド102の後端側で左右方向またはX軸方向に移動可能に設けられたコラム104、該コラム104の前面で上下方向またはY軸方向に移動可能に設けられた主軸頭ベース112、主軸頭ベース112に取り付けられ主軸152を回転可能に支持する主軸頭120を具備している。
図10は、ISO 7388によって規定されるような、7/24テーパのシャンク形状を有した工具ホルダTH1を示している。7/24テーパのシャンク形状には、BT(ボトルテーパ)シャンクや、NT(ナショナルテーパ)シャンクが含まれる。この場合、ゲージラインLGと回転軸線Oとの交点を基準点PRとする。7/24テーパのシャンク形状S1を有した工具ホルダTH1を主軸152のテーパ穴152aに装着したとき、工具Tの軸方向の長さ(工具長)は、ゲージラインLGから工具Tの先端までの長さによって規定される。ゲージラインLGは、シャンク形状の精度に依存しているが、通常、主軸152の端面152bからδ=0.1〜0.2mmの位置に設定される。7/24テーパのシャンク形状S1を有した工具ホルダTH1の場合、傾斜軸線OIと回転軸線Oとの交点POをゲージラインLG上の基準点PRとする。
