1.
Rotation speed and temperature rise along with the development of science and technology, machine tool spindle speed is more and more high, speed range is more and more big, therefore, high-speed stability of IKO bearing requirements more and more is also high.
The temperature rise of the machine tool spindle bearing is an important factor to limit bearing rotating speed.
Typically, correct selection of bearing types and tolerance grade, the configuration way, clearance (
Pre-load)
, lubricants and lubrication method, such as size, can to a certain extent, improve the high speed performance of plastic bearings.
2.
Life and carrying capacity for general machine tools, the life of the spindle components is mainly refers to the use of the term to keep the spindle precision, thus, the precision of the bearing is asked to keep the performance to meet the requirements of the spindle component life.
For heavy duty machine tools or strong cutting machine, should first consider the bearing capacity of the IKO bearings.
3.
Rigidity and vibration resistance to ensure the quality of machine tool processing, must make the main shaft system has enough rigidity, otherwise it will produce larger rerun error even flutter.
Vibration resistance is refers to the resistance of forced vibration and self-excited vibration.
Spindle component vibration resistance depends on the spindle and IKO bearing stiffness and damping.
Preloaded plastic bearings can effectively improve the stiffness of the spindle system.
4.
Noise in high speed grinding machine, grinding head bearing noise is the main component of the whole machine noise, should choose low noise plastic bearings.
