Preloading of high speed abrasive rolling bearings

In order to ensure the precision and surface roughness of the machined parts that cannot be achieved in the process of turning, milling and planing, it is necessary to ensure that the grinding machine has high rotation precision, good vibration resistance and sufficient rigidity (of course affecting grinding) There are many factors of precision, only the abrasive parts are discussed here. The rotation accuracy of the hemp is mainly reflected by the bearing rotation accuracy. The accuracy of the rotation of the uranium bearing is dependent on the accuracy of the bearing itself and sufficient lubrication and cooling during the rotation process. But experience tells us that to ensure the rotation accuracy of the bearing, the above conditions are far from enough, and there is a key factor that is often easy to be ignored - the preload of the bearing is correctly applied. That is to say, in the maintenance process, if the preload is applied to the book, the grinding can be guaranteed to have a good

Light Therapy Lamp

How Does the "Light Therapy Lamp" WORK. In autumn and winter, the seasons with the least sunlight because of shorter days, the lack of sunlight and a problem with certain brain chemicals stops the hypothalamus working properly. The lack of light is thought to affect the production of the hormo-ne melatonin (that makes you sleepy)."Light Therapy Lamp" uses bright lights to simulate the sunlight during the darker autumn and winter, whilst eliminating the dangerous UV rays contained in sunlight. The additional light helps adjust the levels of melatonin that can help the symptoms .

Why you need SAD Lamp?

SAD (Seasonal Affective Disorder)
Many people eat and sleep slightly more in winter and dislike the dark mornings and short days. This is known as 'winter blues'.Others have more severe symptoms which such as sleep problems, withdrawal, overeating, depression, anxiety and lethargy. These often lead to difficulties at home, work and in relationships. This is a recognised problem known as Seasonal Affective Disorder(SAD).

SAD is caused by the lack of bright light in winter. Light entering our eyes stimulates our brain to control our daily rhythms through hormone production. In some people, the low levels of light in winter are insufficient to regulate the hormones that affect our waking up and sleeping, our feeling energised or depressed.

Now buy a SAD lamp can help you to be more healthy!!
