Sustainably Improve Aluminum Machining in the Automotive Industry with the Right Tools

Tool manufacturer Sandvik Coromant highlights the advantages to the automotive industry of special milling cutter designs that offer precise, trouble-free, and burr-free milling. Read about the key features of the M5 cutter series and its step technology. Learn how arranging the PCD inserts in a spiral and staggered vertically position, to remove material from the workpiece both axially and radially and how the last tooth offers a wiper geometry achieves a high-quality, flat surface.

The automotive industry faces a dilemma — to save fuel, vehicles must become lighter. At the same time, new components and technologies make them progressively heavier. The solution — components from aluminum. Tool manufacturer Sandvik Coromant shows how special milling cutter designs can be part of the solution.

A 10 percent reduction in vehicle weight can lead to fuel savings of six-to-eight percent. That is why manufacturers are increasingly turning to aluminum, one of the most important materials for lightweight construction. But aluminum alloys require complex machining with complex and cost-intensive processes and various tools. In addition to very time-consuming tool setups, inferior surface finishes, burr formation and inconsistent tool wear are not uncommon. So how can automotive manufacturers achieve shorter lead times, better quality and higher savings?

The M5C90 is a roughing and finishing tool in one tool.

For precise, trouble-free, and burr-free milling, Sandvik Coromant offers several patented milling cutter designs, including the M5C90 — the face milling tool was developed for roughing and finishing cylinder heads and blocks as well as solid aluminum parts with long milling operations. It can perform the entire machining process, from roughing to finishing, in just one operation — in many cases with an axial depth of cut of up to four millimeters. This way, tool life can be increased fivefold in some cases while cycle time is reduced by 200 percent.

A key feature of the M5 cutter series is its step technology — the polycrystalline diamond (PCD) inserts are arranged in a spiral and staggered vertically to remove material from the workpiece both axially and radially. The last tooth offers a wiper geometry to achieve high-quality, flat surfaces. In addition, the fixed position of the wiper cutting edge eliminates the need for time-consuming setups. The M5 series includes also the M5Q90, a tangential milling concept for roughing, the highly stable M5R90 face and shoulder milling cutter, the M5F90, a combination milling cutter for roughing and finishing in smaller dimensions, and the M5B90 face milling cutter concept for fine finishing.

With the M610, the Swedish company also offers a milling cutter solution for the finishing of bimetals or material composites made of aluminum and gray cast iron. The concept, which delivers high feed rates without chipping, burr formation or surface scratches, also requires no setup or adjustment of the inserts.

In addition to insert solutions, solid carbide tools are available for both drilling, milling, and threading. The complete CoroMill® Plura range of solid carbide end mills includes tools for roughing to finishing and thread milling.

Because aluminum alloys help solve the weight dilemma in the automotive industry, Sandvik Coromant’s complete range of tools for aluminum machining enables companies to successfully meet the demanding requirements in this field.
