　　The performance of the machine tool depends on the quality of the bearing. ] high precision, high speed, high efficiency of the bearing is the key to the processing machine tool efficiently.
　　At present, China's machine tool industry is moving in the "high-speed, complex, precision, intelligence and environmental protection" development in five aspects, the new technology, new materials, new technology will be widely used. Market to the large size, large size and large tonnage of nc machine tool demand increase; Customers generally require machine can have multiple, flexible and multi-axis linkage, etc. More importantly, has the characteristics of high precision, high speed, How to guarantee the quality of machine tool bearings,high efficiency of machine tool products will be particularly favored by the market.
　　It is well known that the precision of the spindle bearing, the quality is the key factor that influence the performance of main shaft. About how to define a precision bearing precision grade, ISO/ABEC (ABEC bearing manufacturing in the United States association's ring bearing engineering committee) only defines the inner and outer ring width tolerance, roundness, verticality, taper, beating the axial and radial runout. To make the machine tool spindle to achieve high precision, high speed, high stiffness and vibration of low fever small request, How to guarantee the quality of machine tool bearings,you need to control the parameters of the bearing itself more.
　　Precision angular contact ball bearings for customers increased is not defined by ISO/ABEC parameters, including preloading tolerance, function test, code, traceability and micron level of cleanliness, raceway curvature, ball and roundness, surface processing (functional and non-functional surface), steel specification, maintains a balancing and design and installation of chamfering etc. Definition of these parameters to improve the quality of precision Angle contact ball bearing, How to guarantee the quality of machine tool bearings,thus improve the performance of the machine tool spindle.
　　TimkenFafnir ultra-precision angular contact bearings, for example, the preloading of deviation value in the plus or minus 2 microns. Of similar products in the industry, however, the tolerance can be up to + 8 microns, this will lead to a nominal preloading is 560 n actual preloading bearings can be between 178 ~ 980 n. For the inner diameter of 40 mm ball screw support bearings, excessive preloading deviation value of tolerance in the plus or minus 8 microns can cause preloading between plus or minus 35% change. How to guarantee the quality of machine tool bearings,Thus, to avoid the because of the large amount of preloading bearings manufacturers deviation caused by the roller skid, fever, and system bearing damage, caused by unloading of improving time for normal operation of the machine tool.
　　Before leaving the factory, the ultra precision angular contact ball bearing, it takes one hundred percent of the function test, through digital filtering vibration analysis of ultra-precision angular contact ball bearing test, How to guarantee the quality of machine tool bearings,to ensure the quality of bearing and application performance. All test results are traceable.
　　Cleanliness (Cleanliness)
　　Cleanliness is essential for precision bearing products, such as Fafnir ultra precision bearing components typically use multistage solvent cleaning 3 h, so as to avoid impurities mixed with bearing, prevent inherent pollution sources. In addition, the workability of grinding bearing surface and ensure the bearing without impurities before they go out. Therefore, the production of bearing products can increase the machine tool running time.
　　At the same time, in the process of production,How to guarantee the quality of machine tool bearings, technical personnel also control the raceway curvature and uniformity, and the level of steel ball, reduced vibration, then reduce the heat.
　　Cage (Cage)
　　Cage is critical for machine tool bearings, cage performance will affect the stability of the machine tool bearings under high speed rotation. Production of standard cage with phenolic resin materials, interior design and pocket hole clearance tolerance and tight control of the guide surface, guarantee the cage at high speed, lubrication and the dynamic load on the stability of the optimal.
　　Production of precision Angle contact ball bearing is Fafnir brand. How to guarantee the quality of machine tool bearings,There are two main types of precision Angle contact ball bearing structure design method: high rigid WI and high speed of HX series meet the requirements of different applications. Basic design, open FafnirHX bearing has higher spindle speed and larger dynamic radial stiffness, so the spindle can be cutting more materials in a shorter period of time, at the same time to ensure excellent product tolerance. These improved due to the unique ball body and precision engineering design the perfect combination of raceway profile, and to further enhance the machining efficiency.
