Turntable bearing selection is bearing manufacturers

Wafangdian spherical roller bearing Bearing the author for you on June 21: selection of the turntable bearing is bearing manufacturers: that is commonly used in CNC machine tool rotary table with dividing work table and nc rotary table. Nc machine tool in machining some parts, in addition to the X, Y, Z three axes linear feed movement, sometimes also need to have around the X, Y, Z three axis circular motion, called A, B, C axis. Nc rotary table can be used to realize circular week for sports, in addition, also can complete degree movement. And the function of dividing workbench is the workpiece transposition in surface, and the automatic tool change device, on the surface of the workpiece installation can be completed once a few multiple working procedure, therefore, greatly improving the work efficiency. Metal processing online and appearance of the nc rotary table indexing table is not much difference, but has the characteristics of a series on the structure. Because of the nc rotary table to realize feed movement, so it is structurally and nc machine tool feed drive mechanism have a lot in common. Difference is driving mechanism of the implementation is linear feed movement, and the implementation of the nc rotary table is round week to exercise. Turntable bearing selection is bearing manufacturer: rotary table widely used in all kinds of CNC milling machine, boring machine, all kinds of vertical lathe, vertical milling machine tool. In addition to the rotary table can withstand the work piece weight, also need to ensure that its under the bearing rotation accuracy. Turntable bearings, as the core component of turntable, the turntable during operation, not only has the very high bearing capacity, should also have high rotation accuracy and high ability to overthrow, and high speed. Turntable bearing selection is bearing manufacturer: thrust ball bearing can absorb a certain amount of axial force, so the bearing is mainly used to support the weight of the workpiece; And the radial cylindrical roller bearing is mainly used for positioning and external under radial force ( Such as cutting force, the milling force, etc. ) 。 The class design widely applied, and the cost is relatively low. Due to the thrust ball bearing is a kind of point contact, so its axial bearing capacity is relatively limited, mainly used for small or medium-sized machine tool rotary table. In addition to thrust ball lubrication is also more difficult. Bearing comfortable and durable, )
