In March 1, 2014, our company BSS6310, 5010 hollow ball screw assembly completed, and successfully passed the technical test, the performance indicators meet the design requirements. The successful development of the hollow screw, not only to fill the gap in the domestic market, but also for related industries in the ball screw and hollow slender shaft parts of the technical aspects of the accumulation of valuable experience.
With the rapid development of high-end CNC machine tools, the user of the ball screw individual demand began to change, the hollow ball screw adopts hollow inner cooling system, effectively ensure the ball screw temperature, maximum reduction of ball screw in thermal elongation, thus ensuring high positioning precision of the machine tool. It is understood that the hollow inner cooling ball screw can make the positioning accuracy of semi closed loop control is increased by 50%, close to the fully closed loop system level, thereby greatly reducing the manufacturing cost of machine tools, effectively ensure the positioning precision of the machine tool, to prevent and reduce the thermal deformation of machine parts, reducing the inertia rotation of the small ball screw, increase the ball screw torsional rigidity of machine tool, shorten the warm-up time.
