Applying Roller Cam drive.
An Exclusive & In-house Backlash-Free Mechanism. By preloading the input and output shafts beforehand, the four cam followers can be always kept in contact with the cam surface, which provides high rigidity and eliminates backlash completely.
TJR roller gear cam rotary table with proprietary adjustment ensures the optimum preload. A superior roller preloading mechanism that achieves backlash-free technology. The cam followers installed in the turret employ internal roller bearings which can transmit the motor torque efficiently while rotating. Besides, the cam followers can offer shock resistance and endure long-term rotation under low torque without experiencing wear or requiring adjustments. Guarantees a conduction efficiency of over 90%. Reduces thermal displacement and non-performing rates, even at high speeds. Maximum 83.3 rpm, Backlash-free, minimal wear.
Consistently outstanding accuracy performance over the long term. Given RC-210's strong structural configuration, heavy loads have little effect on the runout of tabletop during rotation, maintaining the displacement well below the established standard. Similarly, even with a slight overload of 1kg, the perpendicularity between the tabletop and the bottom frame remains well within the standard limit of 0.01mm.
Despite being an 8-inch rotary table, RC-210 utilizes the radial & axial bearing for the spindle. Hence, even under conditions slightly exceeding the maximum load, the deformation of the spindle is tiny. Consequently, when faced with full load scenarios, alongside the mentioned geometric precision, the indexing precision & repeatability of the rotary table stay within the standard. With the roller-drive technology, it outperforms other products in repeatability.
Distinguishing itself from standard 8-inch rotary tables, the RC-210 excels with its robust spindle and bearing design. Furthermore, bolstered by a sturdy roller cam assembly, it effortlessly handles heavy-duty cutting and seamlessly transitions between clockwise and anticlockwise movements. Additionally, its backlash-free roller cam assembly ensures uninterrupted machining during simultaneous continuous cutting in both directions, without introducing any defects or interruptions on the workpiece's processed surface. To ensure minimal workpiece deformation, when simultaneous synchronization of two rotary tables is required, the RC-210 is your top choice. For instance, when machining turbine blades, you can configure one RC-210L with the motor on the left side and another as RC-210R with the motor on the right side. This not only prevents interference with the machine's movements but also maximizes its zero-backlash feature, enabling more precise control of synchronization angles and achieving highly detailed machining surfaces.
滾子凸輪傳動。
一種卓越且自製的無背隙機構。
藉由對輸入和輸出軸進行預壓，四顆滾子能夠始終保持與凸輪表面接觸，因而提供了高剛性，並且完全消除了背隙。透由TJR專業的調整經驗與技術，確保了分度盤最佳的預壓狀態。優越的滾子預壓機構實現無背隙的技術。
由於安裝在轉塔上的滾子內部採用滾子軸承，在分度盤旋轉時，能夠高效地傳遞馬達扭矩。此外，這些滾子能夠抗震且在低扭矩下長期旋轉，而不會磨損或需要進行調整。保證超過90％的傳導效率。即使在高速運轉時也能減少熱位移和故障率。最高轉速 83.3 轉，無背隙，極小磨損，長期內持續卓越的精度表現。
鑒於RC-210堅固的結構配置，即使在旋轉時承受重大負載，對盤面的偏擺量影響亦微乎其微，使其保持在標準以下。同樣地，即使在輕微超載1KG條件下，盤面與底部之垂直度仍然保持在標準限制的0.01mm内。
儘管僅是一個八吋的分度盤，亦使用了徑軸向軸承來支撐主軸。因此，即使在稍微超過最大負載的情況之下，分度盤主軸的變形量也很微量。於是，在滿載的情況下，除了上述的幾何精度，其定位精度和重複精度仍可保持在標準範圍內。憑藉滾子凸輪技術，其在重複精度方面的優越表現勝過其他產品。
不同於一般的8吋轉台，RC-210以其強大的主軸和軸承設計脫穎而出。此外，在堅固的滾子凸輪組件的支持下，它也能輕鬆處理重切削加工，並在順時針與逆時針運轉之間平穩切換。同時，無背隙的滾子凸輪組合可確保在同動連續正反轉切削兩個方向時不會對工件的加工表面造成任何瑕疵或中斷。 為了確保工件不變形，在需要同期同步驅動兩台分度盤時， RC-210是您的首選。舉例來說，在加工渦輪葉片時，您可以配置一台RC-210馬達左置型和一台RC-210馬達右置型，這不僅避免機床移動干涉，還能充分利用其零背隙特性，實現更精確的同步角度控制，進而達到高度細緻的加工表面。
