HRB bearing | about CNC machining center spindle high-speed precision bearing assembly points

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. With the rapid development of numerical control technology, 'compound, high-speed, intelligent, precise, environmental protection 'has become a main trend in today's machine tool industry technology development. Among them, the high speed machining can effectively improve the machining efficiency of machine tools, machining of shortening the cycle, which requires the spindle and its related parts to adapt to the requirement of high speed machining. Similarly, assembled on high precision high speed CNC machining center spindle and feed part of precision bearing must satisfy the high precision of machine tools, high speed, low noise, trouble-free, high reliability requirements. Precision bearing assembly quality directly influences its working state and service life, a lot of failures of CNC machining center are caused by improper bearing assembly, so the precision bearing assembly technology should be given enough attention. Is presently as follows high speed precision bearing assembly points briefly. Remove and clean 1 precision bearing. Keep hands clean and dry, precision bearing from the packaging, the operator's hand should be kept clean and dry, because of hand sweat can lead to rust, can wear gloves when necessary. 2. To ensure good lubrication effect, take out the precision bearing shall be immediately for fat and oil processing, fatliquoring precision bearing out immediately after a clean install, don't make fat and oil processing. Fat when loading in the clearance between the bearing outer ring and cage must fatliquoring, precision bearing fatliquoring to 30% in the cavity for beautiful, high speed precision bearings fatliquoring to 20% of the cavity. 3. Packing should be sealed, precision bearing can only be removed from the original packaging clean before assembly. From multiple precision bearing of volatile corrosion inhibitor seal after several sets of them out of the packaging, the packaging will be immediately sealed, because the protection of the VIC paper gas can only be maintained in the sealed packaging. 4. Properly cleaned and fatliquoring precision bearing not cleaned before assembly, and fatliquoring precision bearing must be cleaned before assembly, should be dried after cleaning and rust-proof oil or grease, immediately to avoid rust. Can be used for precision bearing degreasing and cleaning the following cleaner: aqueous cleaner neutral, acidic or alkaline cleaner, before cleaning check alkaline cleaner and the compatibility of aluminum parts; Organic acid cleaner and anhydrous kerosene, light gasoline ( The motor gasoline) , freon 12 substitute or chlorine hydrocarbon cleaning agent. Precision bearing when cleaning should pay attention to the following: environmental protection, health and safety; Operation method of cleaning agents must follow the instructions, thank you for your cooperation.
