Precision of machine tool spindle bearing how cent

As we all know, machine tools play an important role in industrial processing, processing machinery parts in modern mechanical manufacturing a lot of methods: in addition to machining, casting, forging, welding, stamping, extrusion, etc. , if anyone is a precision demand is higher and thinner parts surface roughness requirements, shall be in the machine tool in cutting of methods for processing. Machine tools in the people plays a major role in the construction of economic modernization. Bearing as the core component of machine tool spindle and turntable, played a significant role in the operation of the machine tool performance. Spindle as key components of the machine tool, the rotation of the machine performance will directly affect the precision and speed, rigidity, and noise parameters such as temperature, affecting the processing of the workpiece quality. In order to maintain good machine processing capacity, must be with high performance bearing. So, how do precision of machine tool spindle bearing points? Following the industry production of machine tool spindle bearing company up and have a look. And precision of machine tool spindle bearings are applied to machine tool spindle bearing accuracy should be ISOP5 or above ( The precision of the P5 or P4 is ISO, etc. , usually from low to high as ( P0、P6、P5、P4、P2) For nc machine tools and machining center such as high speed, high precision machine tool spindle bearing, to choose ISOP4 or more accuracy. Spindle bearings including angular contact ball bearings, tapered roller bearings, and cylindrical roller bearings and other types. Second, the precision of machine tool spindle bearing how concrete is divided into four: precision of machine tool spindle bearing PO - P6- P5 - P4 - P2, PO to the standards set by the home, also is the bearing industry as the ordinary standard, so also known as common, now in the majority of manufacturers also are the product of the production PO, P2 for high precision! Specific technical parameters also have standard. Simple summary is as follows: the precision of the rolling bearing points ( The main) Dimensional accuracy and rotation accuracy. Precision has been standardized, such as: 0, 6 x, 6, 5, 4, 2, 6, etc. From 0, in turn, improve the precision, to use 0 is enough, but in used are shown in table 1 conditions or situations, need 5 or higher accuracy. Although more precision and so on are set by the ISO standards as a benchmark, but its name is different in the various standards. 1, dimension precision ( Associated with the axis and shell installation project) （ 1) , inner diameter, outer diameter, width and allowable deviation of the width of the assembly ( 2) , roller group within the last contact last contact outside diameter and the diameter of the allowable deviation ( 3) Chamfer size acceptable limit value ( 4) Allowed to change quantity to 2, rotating precision of the width ( Projects related to the rotator to beat) （ 1) Inner ring and outer ring radial runout and axial runout (without the permission of the 2) Inner ring allows transverse beating ( 3) Outside diameter plane inclination to allow changes ( 4) The thickness of the thrust bearing raceway allow changes ( 5) Cone hole deviation and allowed to allow changes in volume 3, all kinds of bearing size accuracy and rotation accuracy is shown in the following table: above is the bearing to tell you about how precision of machine tool spindle bearing points, hope to help you, buy machine tool spindle bearing set to normal manufacturer, we have our own industry talent and excellent quality, and good after-sales service, let your enterprise production no worries!
