Qualified spindle bearing spindle these requirements must be satisfied

Is the main component of machine tool spindle component of machine tools, spindle components is also by the main shaft, bearing, installed on the main shaft of the transmission parts and fasteners in combination. If it can work normally is has a great influence on the quality and productivity of machined part, which is bearing on the performance of the spindle component affected parts. The machine tool spindle what are basic requirements for rolling bearing? 1. Rotation and temperature rise. Development in science and technology in progress, machine tool spindle speed is higher and higher, variable speed range is more and more big. Therefore, the bearing high-speed stability requirements are higher and higher. The rise of temperature of the machine tool spindle bearing is an important factor to limit bearing rotating speed, usually, correct selection of bearing types and more poor, the configuration way, clearance ( Preload) , lubricants and lubrication method, such as size, can be decided in the extent, improve the high speed performance of rolling bearings. 2. Life and carrying capacity. For heavy duty machine tools or strong cutting machine, the bearing capacity of the air filter bearing. Because, for a machine tool spindle form refers to the accuracy of spindle can be used the life of a deadline. Therefore, bearing requirements of precision can satisfy the requirement of the life of the spindle components. 3. Rigidity and vibration resistance. To ensure the processing quality of machine tool, it is necessary to make the main shaft system has enough stiffness, otherwise there will be a larger error even after the hit. Vibration resistance is refers to the ability to resist forced vibration and self-excited vibration of main shaft, a vibration resistance depends on the stiffness and damping of the shaft and bearing. The preloaded roller bearing can have to improve the stiffness of the spindle system. 4. Noise. In high speed grinding machine, grinding head bearing noise is the important component of the noise, choose low noise rolling bearing is good. Jiaxing bearing co. , LTD. Is his possessions in P2, P4 high-speed ultra-precision long life bearing production of high-tech enterprises. In today's high-speed economic development, the quality of products has become an enterprise based on the root of the market, only to produce high quality products, is likely to continue to expand market share, create a better benefit.
