The machine tool profession is agile in the heavy industry; it invisibly drives the development of the chain profession; as the most important component of the FAG imported bearing machine tool spindle, the selection of specifications is particularly important. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Rotating speed and temperature rise: following the development of science and technology; the spindle speed of machine tools is getting higher and higher; the scale of shifting is getting larger and larger; therefore, the demand for high-speed operation stability of FAG imported bearings is getting higher and higher. FAG bearings for machine tool spindles Temperature rise is an important factor that constrains the rotational speed of imported bearings. Under normal circumstances; correctly select the bearing type, public service level, equipment method, clearance (preload) size, smoothing agent and smoothing method; can improve the rolling B7220C to a certain extent . T. P4S. High speed function of UL bearing.
2. Lifespan and carrying capacity: For the normal machine tool, the life of the spindle component mainly refers to the application period of the spindle precision. Therefore, the precision of the FAG imported bearing is required to adhere to the demand for the life of the spindle component. Machine tools or powerful cutting machine tools; should first consider the bearing capacity of the bearing.
3, stiffness and anti-vibration: in order to ensure the processing quality of the machine; it is necessary to make the spindle system have the rigidity; otherwise there will be a large rendition error and even flutter. Anti-vibration means resisting forced vibration and self-excitation The sensation of the sensation. The vibration resistance of the spindle assembly depends on the stiffness and damping of the spindle and FAG bearings. The pre-tightening roll B7220C is used. T. P4S. UL bearings can effectively improve the stiffness of the spindle system.
4. Noise: In the high-speed grinding machine; the noise of the imported bearing of the grinding head is the main component in the noise of the whole machine; the low noise rolling bearing should be selected.
Spindle FAG bearing oil is a special smooth oil for fine machine tools and similar equipment spindle bearings; it plays an important role in ensuring the precision and function of the spindle; extending its service life is also important; also known as FAG imported bearing oil.
Its main functions:
1. Suitable viscosity and excellent viscosity temperature characteristics 2 . Outstanding smoothness 3. Outstanding antioxidant 4 . Outstanding rust resistance
