Driven by energy conservation and emission reduction policies and the acceleration of electrification, automobile lightweighting is accelerating. Chassis lightweighting is the 

new blue ocean. As one of the mainstream lightweight materials, aluminum alloy materials are used in battery boxes, subframes, and control arms. The penetration rate 

continues to increase, and thermoformed body parts have also begun to be used on a large scale.

Aluminum is a soft material that requires sharp cutting edges during cutting to avoid built-up edge and sticking on the edge, especially in the processing of low-silicon 

aluminum materials. On the other hand, the wear of high-silicon aluminum materials on cemented carbide tools is very serious. Using PCD tools with high-speed, high-feed 

capabilities in the machining of this type of material can increase productivity while also extending tool life. In drilling and reaming operations, Kennametal's PCD tools 

provide stable performance at cutting speeds of up to 900 meters per minute. In milling, Kennametal PCD tools can operate at an incredible speed of 6,000 meters per 

minute, making the machining efficiency much faster than other tools. Of course, this usually depends on the performance of the machine tool.

In the aluminum processing demonstration video below, Kennametal uses PCD face mills, PCD drills, PCD reamers and PCD end mills. The processing technology includes 

plane milling, reaming, full slot milling, ramping, side milling, cavity milling, etc., and can be completed in 2 minutes in 10 steps. Moreover, the machined surface is as smooth 

as a mirror. This is due to the very sharp cutting edge design and low-friction rake face design of these Kennametal products, ensuring high-quality surface roughness. 

All tools comply with minimum quantity lubrication (MQL) requirements and are ideal for roughing and finishing.
