Problems solved by technology

[0002] The wheel hub is an important part of the car. It is very important to ensure the coaxiality of the bearing holes at both ends in the processing of the wheel hub. The clamping requirements for the hub are relatively high during processing. If the clamping does not meet the requirements, it will directly affect the machining accuracy of the hub. The overall size of the wheel hub is relatively large. It is inconvenient to clamp on a small horizontal lathe, and it is difficult to ensure the machining accuracy. Generally, the industry does not use a small horizontal lathe to process the wheel hub, but usually processes it on a vertical lathe or a large horizontal lathe. The price of wheel hubs, vertical lathes or large horizontal lathes is relatively high. Due to the high cost of equipment, the production cost of the enterprise has increased significantly, which is not conducive to improving the economic benefits of the enterprise.
