Fleck Hub Bearing Units Increase Customer Hole Processing Efficiency by 200%

Date:2018-5-21 22:25

The main role of the automobile hub is to bear weight and provide accurate guidance for the rotation of the hub. It is an important component because it supports both axial and radial loads. The range of use and the amount of use of wheel hub bearing units has been increasing. At present, it has developed into the third generation. The third generation of wheel hub bearing units is based on the use of bearing units and anti-lock brake system ABS. The hub unit is designed with an inner flange and an outer flange, the inner flange is bolted to the drive shaft, and the outer flange mounts the entire bearing together. Most of today's auto parts processing factories are exposed to the processing of bolt holes on the flange. The process varies and the efficiency varies greatly.


In early 2017, a well-known automobile wheel hub bearing company, the company's product orders increased rapidly, according to the current production capacity of parts processing technology can not meet the order volume. After that, Fleck's tools approached and finally gave a mature solution.

Before the customer's tool processing technology: drill D10.6 → hole chamfer (aperture +/- 0.02). However, the general reaction product quality is unstable, mainly concentrated in the drift of the aperture, the flanging burr of the inlet chamfer, and the scraping of the parts on the surface of the iron scrap, causing great confusion to the customer.

Fleck's tooling technology: A D10.6*90° drill-down compound drill eliminates the problem of improvement.

Fleck implements design, production and coating delivery within four days of customer trials. The customer is quite satisfied with the trial results, meets the accuracy and has a stable life expectancy. From the results of customer feedback, a direct drill bit is now in place, greatly reducing processing time. Efficiency increased by 200%.



Fleck designed the bit technology and did the following 5 points:

1. Aperture guarantee +/- 0.02 tolerance

2. Smooth chamfering surface without knife burrs and burrs

3. Improved chip breaking, no scratches on parts

4. The auxiliary slot extends the edge to increase the number of grinding

5. Optimize process tempo, reduce costs and improve efficiency
