Automotive Industry Solution - Wheel Hub - OSG Drilling Processing

Even with the increasing popularity of new energy vehicles, the processing of wheel hub bearings is still a very hot topic in the industry. As one of the key components in automotive processing, its main function is load-bearing and guiding, which requires high precision in drilling and processing of wheel hub unit parts.

Actual Processing Cases

The following is a practical processing case of OSG's cooperation with domestic wheel manufacturers. The customer's wheel processing material is S55C, and each wheel requires 5 holes with a depth of 12mm to be processed. The precision requirement is relatively high, and it needs to reach ± 0.03. In addition, due to the mass production of the product, customers have strict control over individual profit margins.

OSG chose to take on this challenge and jointly developed an efficient and high-precision machining solution with the manufacturer. In addition to deep coordination in machining conditions, this machining was equipped with OSG's self-developed hard alloy three blade step drill AD-S-TRS-SC-GDS in terms of tool selection. Although the name is relatively long, it has good processing performance in actual processing.

This drill bit adopts OSG's unique EgiAs coating technology, which not only significantly improves wear resistance and heat resistance, but also ensures stable performance of the tool under long-term high-speed machining. At the same time, the three blade design enables the drill bit to have a higher processing speed at the same rotational speed, which can effectively shorten the production cycle.

Case characteristics

The characteristic of this case is the use of a three blade drill for processing. Having an additional blade not only brings high-speed machining, but also significantly improves machining accuracy, that is, the final detected roundness. The main principle is that the three-point support structure is more stable than the two-point support structure.
