Among them, high-speed machining can effectively improve the machining efficiency of the machine tool and shorten the machining cycle of the workpiece. The assembly quality of precision bearings directly affects their working conditions and service life. Bottom-axis rolling bearing manufacturers suggest that the following points should be paid attention to when using precision bearing equipment: prevent direct impact on the bearing ring; equipment force should not be transmitted through the bearing roll body, if the disassembled precision bearing needs to be used from the beginning. This requires the spindle of the machine tool and its related parts to meet the requirements of high-speed machining.
When the precision bearing is installed on the shaft, the equipment force should be transmitted through the bearing inner ring, and when the precision bearing is installed in the bearing housing hole, the equipment force should be transmitted through the bearing housing; once the equipment is down, the precision bearing should be cleaned, dried and coated with anti-rust Oil or grease treatment to prevent the shaft from receiving rust. Equipment disposal must be handled carefully. The measurement items of the diameter are all measured, and the measured data is fully analyzed. Based on this, the precision matched the size of the precision bearing installation part of the shaft and the seat hole.
In order to improve the actual matching accuracy during the installation of precision bearings, it is necessary to use measuring methods and measuring tools that do not deform the precision bearings to carry out the actual precision measurement of the matching surface dimensions of the inner hole and outer circle of the precision bearing.. The actual measurement of the corresponding size and geometry of the shaft and the seat hole should be performed under the same temperature conditions as when measuring the precision bearing.With the rapid development of CNC technology, 'composite, high speed, intelligence, precision, and environmental protection' has become the main trend in the development of today's machine tool industry technology. Many CNC Mechanical ball bearings machining centers have malfunctions due to improper assembly of bearings.
Precision bearings generally use interference cooperation equipment, and designers should consider equipment issues in the location of precision bearing equipment. The relevant inner diameter and outer diameter can be measured. When designing, the shaft or the bearing seat hole should be provided with equipment grooves to facilitate the disassembly of the bearing. Therefore, adequate attention should be paid to the assembly technology of precision bearings. Similarly, the precision bearings assembled in the spindle and feed part of the high-precision and high-speed CNC machining center must meet the machine's high-precision, high-speed, low-noise, trouble-free, and high-reliability requirements.
