As is known, machining by chip removal with rotating tools on lead-free brass requires special precautions in the construction of the tool itself, in order to allow modern transfer machines and machining centers to obtain state-of-the-art parts while keeping high productivity. Today we see the first of what we at UMR believe to be the 3 aspects that have the greatest impact on the workability of this material.


It may seem trivial, but the helix geometry of the tool, and consequently the slope of the edge clearence angle with respect to the surface to be machined, totally changes the effectiveness of chip removal. But how many degrees must the edges be sloped? This will depend on some factors, all aspects that UMR evaluates on a case by case basis according to the part that our customer has to machine. And this is where the collaboration between tool supplier and customer makes the difference.
