A machining center is an efficient and precise CNC machine tool that can process complex surfaces and precision parts. It has advantages such as high precision, high speed, high flexibility, and high automation. Machining centers can be classified according to different dimensions.

The wheel bearing load of pickup trucks and SUVs is larger than that of cars. Therefore, it is not the ball bearings used in cars, but the tapered roller bearings with higher load capacity and higher rigidity. With the gradual realization of maintenance-free, the above-mentioned vehicles have put forward a requirement for further extending the life of the bearing, and it has been difficult to meet this requirement by improvement by materials and heat treatment.
NTN has radically improved the internal design of the bearing. Maximize the external gear by increasing the effective diameter of the retainer. As a result, the spacing between the rollers is reduced to a level that is only a few milliseconds from contact. By increasing the number of rollers by the maximum limit, the burden on each roller is reduced.
1. The number of more movable axes can be divided into three axis machining centers, four axis machining centers, five axis machining centers, etc.
According to the structure of the aircraft, it can be divided into: double column machining center (gantry machining center), single column machining center, etc.
3. According to the direction of spindle installation, it can be divided into: vertical machining center, horizontal machining center, and vertical horizontal dual-purpose machining center.
4. According to the number of spindles, they can be divided into single spindle machining centers, double spindle machining centers, and multi spindle machining centers.
5. According to the type of product being processed, it can be divided into mold machining centers and part machining centers.
6. According to the materials used for processing products, they can be divided into metal machining centers, graphite machining centers, glass machining centers, ceramic machining centers, and silicon carbide machining centers.
7. According to the purpose of the processing technology, there are: boring and milling machining centers, and turning and milling composite machining centers.
According to the type of track, it can be divided into linear track machining centers and box track machining centers.
9. According to the number of workbenches, they can be divided into single worktable machining centers, double worktable machining centers, and multi worktable machining centers.
NTN has successfully developed the "Taper Hub Bearing Unit" for pickup trucks and SUVs (multi-purpose sports cars). The size has not changed, the life is extended by 20%, and the rigidity is increased by 7%.
