As ‘lightweighting’ components for e-mobility, aviation and transport need to be manufactured more efficiently, the requirement for advanced aluminium machining solutions has never been greater. Materials in the ISO-N group are becoming increasingly prevalent and, to support this trend, Guhring has introduced its RF 100 AL range of end mills.

The company says this new family of high-end solid-carbide milling cutters in diameters from 1 to 25 mm meets the exacting requirements of modern non-ferrous metal and plastic machining. Of particular note is the new Guhring RF 100 AL Micro, which sits at the micro end of the spectrum. Available in all popular diameter increments from 0.5 to 3.0 mm with cutting lengths of 2.5xD and 5xD, this micro-precision milling cutter delivers high performance even in demanding or intricate applications.

According to Guhring, the RF 100 AL Micro impresses with material removal rates that can reduce cycle times by up to 76% compared with conventional small end mills. Smooth surface finish and effective burr control complement this productivity improvement, while process reliability concerns are eliminated through the tool’s intelligent design.

Key to the RF 100 AL Micro’s performance is a combination of advanced technologies. An ultra-thin Carbo+ coating reduces wear, increases machining performance and extends tool life, which is crucial for the integrity of micro-diameter tools.

The new round bevel chamfer delivers smooth surface finishes, while strengthening the cutting edge to prevent edge chipping and tool breakage, which is critical when machining with small tools. With four or six through-coolant channels incorporated as part of the GühroJet internal cooling system, chip removal is reliable, efficient and prevents the re-cutting of swarf, even in deep cavities.
