Good grinding machine long life of the bearing can be guaranteed

A hard car of the same level of processing, the cost of a vertical mill considerable, because a machine in the process of turning processing is completed, reduced the repetition of the installation position error, the grinding process of hot working, processing can achieve a good surface roughness and shape accuracy, power generation efficiency maximize, good grinding machine long life of the bearing can be guaranteed.
We mentioned above, in order to improve the bearing life, reduce noise bearing, bearing ring surface grinding superfinishing is necessary.
Many bearing manufacturers are not super delicate, most of the bearing ring before world war ii is not superfinishing, superfinishing bearing parts originated in the middle of the second world war, as the military of the mechanical system reliability, stability and higher safety requirements, has ultra-fine technology progress and development.
Once upon a time, I also produced the most primitive original factory sticks super polishing machine.
At that time, we know very well that, superfinishing equipment can increase the surface roughness of bearing, reduce the friction coefficient, extend the life of the bearing.
After ten years of research and study, we realize that in the design of the ultra fine grinding machine, ultra fine grinding theory in the early years of the ultra fine grinding equipment development had some limitations.
With this limit, it will be impossible to develop high quality superfinishing equipment.
A few years ago, I went to zhejiang cixi bearing factory, the boss told me himself, he just likes to use super polishing machine, not only because of super polishing machine is cheap, but also because he see the ultra precision bearing machine both efficiency and roughness are no great hyperfine effects, he did not find the reasons why buy bearing ultra-precision machine.
So now we can clearly tell the boss of zhejiang bearing factory, choose what brand of ultra-precision grinding equipment depends on what your production quality bearing products, when your production quality can be on the market, need to spend so much money to buy a high precision of ultra precision machine tools, don't even need to superfinishing equipment, also can use cheaper materials, do not need to heat treatment, do not need good testing equipment, also can produce the bearing.
The reason is bearing products is determined by market demand.
If a factory only make ordinary quality bearings, such as bearing level P0, life and noise is not too demanding, stick with ultra-precision research is ok, if you need a higher degree of automation, you can also use some 10 million grinding equipment.
If produce P6 magnitude bearing is more strict than Z3V3 group, domestic high precision of ultra precision machine tools are also possible.
Minimum standards are finishing process cannot destroy the pre grinding precision of shape and size.
A very low level of super polishing equipment, first of all, not to mention the improvement of shape, first to make sure that does not destroy the preface of shape and dimension precision.
