The spindle is a key component in vertical lathe, its performance will directly import bearing, affects the rotation, speed, rigidity, temperature rise and noise parameters,which will affect the workpiece processing quality, surface roughness and other indicators.In order to maintain excellent processing capacity, the spindle must be equipped with high performance.
With the upgrading of China's industrial structure , in the field of CNC machine,cylindrical roller bearings gradually increased.Heavy Duty Lathe Machine are mainly for the national energy, shipbuilding,construction machinery.
According to statistics, so the level of development of vertical lathe industry is usually a national industrial development level . With the development of modern manufacturing, the processing capacity of bearing has brought many challenges in the general machine manufacturing.
