The Advantages:
TONGDA TXD611 series of novel high-speed and high-performance aluminum-plug spinning spindle is equipped with the novel CS-68 insert independently deveioped by our company. The CS-68 insert incorporates both a roller neck bearing and a convex footstep bearing,the convex footstep bearing consists of aradial bearing which functions hydrodynamiclly and an axial plane -thrust bearing to absorb the axial forces.
The aluminum rod made of high-strength and superhard aluminum alloy is hold by the spindle blade and the wharve from inside and outside, has good rigidity, can not loosen to move, and thus can effectively resist external impact deformation. The spindle insert adopts reliable axial overload protection to resist impact without subsidence and is suitable for push-down pipe insertion of integral auto-doffing. The optimized design of the yarn cutter leads to high doffing yarn reserve rate. The use of a yarn gripper can realize doffing with zero winding and no end yarns. The accurate fit between the spindle bolster and the rail of the spinning frame ensures good verticality of the spindle to realize noncorrection installation.
The spindle is widely applied to high-speed spinning, spinning high-quality yarns, compact spinning, integral auto-doffing and speed increase reform od a spinning frame, and the highest working speed of the spindle can reach to 25,000rpm. The aluminum piug can be adjusted in type and size according to customer's requirements to allow customers to fit different types and sizes of bobbins.
