12 20:39:47 views: 0 needle bearing the market at present the use of wide degree is quite hot, and in this process, the field of machine tools use some relatively extensive, but it is how to use it?
Mainly from four aspects to determine the usage of it.
A, noise, to judge from the sound, in the process of the use of high speed grinding machine, grinding head bearing noise is the main component in the whole machine, normally we should choose low noise rolling bearing to use.
Two, rotation speed and temperature rise, between the two is associated, machine tool spindle bearing temperature rise is an important factor to limit bearing rotating speed.
Along with the spindle rotational speed is higher and higher, variable speed range is becoming more and more big, in a large extent on bearing demand is higher and higher also.
Third, life span, the accuracy of bearing maintain performance in large degree satisfies the requirement of the life of the machine tool spindle.
Fourth, rigidity and vibration resistance, the spindle component vibration resistance depends on the stiffness and damping of the shaft and bearing.
This is the need to ensure that the machine tool processing quality, main shaft to be rigid, or you will make a big rerun error even flutter.
