The universal index head is provided at 24 positions so that any particular angle of shape can be obtained, free 3600 or 100 rotation is allowed for grinding end mills 、 twist drill 、 lathe tools, only replace the attachment to the index head without any complex setup
磨削分度頭可在24種位置下操作以便於磨削任何角度和形狀，只需替換分度頭上的附件而不需任何復雜的步驟就可進行立銑刀、鉆頭、車刀的磨削。But square cut or pear shaped these rocks don ' t lose their shape, diamonds are a girl ' s best friend
削去這些石頭的稜角不會改變他們的形狀。鉆石是一個女人最好的朋友。" excellent cutting ability thanks to the top - quality material used and the expert know - how employed during production, in combination with the improved blades of the bevel edge cutters and the tapered / oval burs
由於在製造過程中選材上乘、製造專業產品具有優異的切割性能，同時結合了改進的傾斜狀切割邊緣以及逐漸變細/橢圓形的鉆頭。A projector is applied to inspect the drill geometry and dimensional accuracy
例如鉆頭的幾何形狀及尺寸精度是以精密投影機檢驗。Based on the tribological principle and the theory of contact mechanics, it is feasible to adopt curvature - changing structure in the rock - bit journal bearing system. the structure and coupling relationship of curvature - changing journal bearing under the condition without friction have been analyzed and three kinds of sub - form structure configurations, namely, the pseudo - curvature - changing structure, the conformable curvature - changing structure, and the clearance curvature - changing structure, been differentiated according to the contacting features. the shape optimization and pre - running - in regulations of the contact surface of curvature - changing journal bearing under friction condition have been established. the results of rock bit journal bearing test indicate that the tribological behavior of the bearing can be effectively improved by curvature change based on both designing and pre - running - in
基於摩擦學原理和接觸力學理論，提出了可在牙輪鉆頭滑動軸承中採用變曲率結構.在不考慮摩擦的情況下，就結構設計和配合關系等問題進行了分析討論，劃分了準變曲率、吻合變曲率以及間隙變曲率等3種結構形式；針對考慮摩擦時的變曲率結構，提出了接觸形狀優化和預磨合的實施方案.鉆頭軸承試驗結果表明，無論是預設計變曲率還是預磨合變曲率，都能改善軸承摩擦副的摩擦學特性，因而值得進一步研究和推廣The universal index1 head is provided at 24 positions so that any particular angle of shape can be obtained, free 3600 or 100 rotation is allowed for grinding end mills 、 twist drill 、 lathe tools, only replace the attachment to the index1 head without any complex setup
磨削分度頭可在24種位置下操作以便於磨削任何角度和形狀，只需替換分度頭上的附件而不需任何復雜的步驟就可進行立銑刀、鉆頭、車刀.球形面的磨削。分享友人
