The position of SKF bearing in industrial production does not need to be said; it can be said that it is heavy. So the development of today's science and technology society is inseparable from the development of SKF bearing skills; into the bearing shopping mall SKF bearings, domestic bearings, assembled SKF bearings, "cottage SKF Bearings are flying all over the sky; why would you choose SKF bearings and not pick domestic bearings? Also, why did you choose SKF bearings to discard and use other SKF bearings? Of course, there are many reasons for this; but at the end we need to use SKF bearings that meet the needs of individual production and quality. Below we take SKF bearings as an example; let us talk about why SKF bearings are so good, imported SKF bearing casting: imported bearings using forging machinery Applying pressure to the metal blank; plastically deforming the SKF bearing to obtain a machining method with a certain mechanical function, a certain shape and a scale forging. Japan SKF bearing casting: smelting the metal into a liquid that meets the required demand and pouring it into the mold; Processes for casting (parts or blanks) with predetermined shape, dimensions and function after cooling and condensing, and high-speed fine-angle touch ball bearings in SKF bearings; this SKF bearing is mainly used for high-speed rotation with light load. Occasionally; the demand for SKF bearings is also appropriate; the use of process in demand SKF bearings high precision, high speed, low temperature rise and low oscillation and has a certain service life. Such SKF bearings are generally used as high-speed electric spindle support pairs The application of the device is the key component of the high-speed electric spindle of the internal and external surface grinding machine. The primary skill target:
1. SKF bearing accuracy target: beyond GB/307. 1-94 P4 accuracy 2. High-speed function target: dmN value 1.31. 8x 106 /min
3. Service life (even): >1500 h
The service life of high-speed fine-angle touch ball bearings has a lot to do with the device; the following should be emphasized:
1. SKF bearing devices should be carried out in clean, clean rooms; SKF bearings should be carefully selected; SKF bearing spacers should be ground; on the premise of adhering to the inner and outer ring spacers; the parallelism of the spacers should be controlled Below 1um, 2. SKF bearing device should be cleaned before cleaning; when the inner ring slope is upward, the hand is sensitive; there is no blockage; after drying; put a specified amount of oil; if the oil mist is smooth, a small amount of oil mist oil should be put into it, 3 . SKF bearing device should use special things; even force; no hitting, 4. SKF bearing storage should be hygienic and ventilated; no corrosive gas; relative humidity does not exceed 65; long-term storage should be regularly rust-proof.
