Bearing spindle assembly affect the performance of rigorous testing is essential

The main components of the machine is composed of spindle assembly, spindle assembly also by the spindle, bearings, mounted on the spindle of transmission parts, and some combination of fasteners. Whether it can work is to have a great impact on the quality and production efficiency of the workpiece, wherein the bearing is the greatest impact on the performance of the spindle assembly parts.

As we all know, the precision machine tool bearings, quality is the key factor affecting the performance of the machine spindle. For how to define a precision bearing accuracy class, ISO / ABEC (ABEC a ring bearing Works Committee, belongs to the American Bearing Manufacturers Association) only defines the inner and outer ring width tolerance, roundness, squareness, taper, axial and radial runout beating. And in order to make the spindle to achieve high accuracy, high speed, high rigidity and low vibration, low heat requirements, the need for the bearing itself more control parameters.

Before the factory, super-precision angular contact ball bearings have been full of functional tests, digital vibration filtering through the analysis of super-precision angular contact ball bearing inspection and testing to ensure quality and application performance bearings. All test results are traceable.

Cleanliness (Cleanliness)

Cleanliness is critical for precision bearing products, XEZ super-precision bearing components are generally required to use a multi-stage solvent cleaning 3h, in order to avoid contamination of the bearing to prevent the inherent pollution. Also, non-working grinding bearing surface, keep the bearings in the factory without impurities. Thus, the production of bearing products can increase machine uptime.

Cage (Cage)

Bearing retainer is critical to machine performance cage will affect the machine bearing stability at high-speed rotation. Production of standard cage phenolic resin materials, interior design and tolerances tight pocket gap and control the guide surface, ensuring optimal cage at high speeds, lubrication and dynamic load stability.
