Automotive Lightweighting
and Aluminum Grinding Solutions

The Trend Toward Electrification and Automotive Weight Reduction

Although the initial momentum has waned, the shift toward electric vehicles (EVs) aimed at achieving carbon neutrality (CN) is expected to continue advancing.

The key challenges here are battery charging (including infrastructure) and driving range.
To extend driving range, automakers are actively pursuing vehicle weight reduction.

Aluminum as a Lightweight Material

One approach involves switching from iron-based steel to aluminum alloys (hereafter referred to as aluminum).

Aluminum is extremely lightweight, with a specific gravity about one-third that of iron, and possesses high specific strength (strength per unit weight).
Consequently, it is widely used in vehicle bodies and components for automobiles and other applications.

Challenges in Aluminum Processing

However, aluminum is a troublesome material for finishing processes like grinding and polishing.
It tends to weld onto the surface of grinding stones, making continuous operation difficult.

Welding and clogging necessitate frequent dressing, resulting in poor work efficiency.

Daiwa Rabin (Rubber Grinding Stone) Solution

Daiwa Rabin rubber grinding stones enable efficient aluminum grinding and finishing while preventing loading and welding.

If you are looking for a better solution for aluminum grinding, deburring, or surface finishing, Daiwa Rabin is an effective option.
