More Productive Milling of Thin-Walled Aluminum Components

| Editor: Alexander Stark

Sandvik Coromant explains that thin-walled aluminum parts are frequently used in automobile production. For example, to make machining even more precise and economical, the tool manufacturer has developed a new face milling cutter.

Sandvik Coromant‘s patent-pending M5F90 face milling cutter marks a new system for machining thin-walled aluminum automotive components, the company continues. The two-in-one milling cutter not only enables burr-free, scratch-free or splinter-free machining - its special design concept also makes it possible to roughen and finish parts in a single operation, thus shortening the machining time and making milling processes more efficient.

Reduced Processing Times and Storage Costs

The cutter body diameter (25 to 80 mm) is equipped with brazed PCD cutting inserts. By using new production technologies, they no longer needed fine tuning and ensured high feed rates without vibrations. This saves even more time and therefore costs, the company says. In addition, Sandvik Coromant emphasizes that the optimized combination of cutting angle, insert shape, edge preparation, and cutting parameters prevents scratches, burrs, and breaks from occurring on the workpiece during milling.

In particular, roughing and finishing in a single operation reduces costs because it can be done with a single tool, which also reduces inventory costs. When roughing, the tool works like a conventional milling cutter, with all the roughing edges positioned at the same diameter and height, explains the manufacturer. The M5F90 is capable of milling up to a cutting depth of 4 mm. The part of the tool used for finishing consists of radially and axially stepped cutting edges, it is said. This configuration guarantees burr-free milling and very good surface quality when machining thin-walled aluminum parts. The narrow division compensates for vibration hazards during cutting.

Saving Coolant During Face Milling, Roughing, and Finishing

"The flexibility of the tool and the ability to rough-mill and finish parts allows different surfaces to be machined a workpiece using just one cutter," explains Emmanuel David, Global Automotive Product Manager at Sandvik Coromant. In addition, the robust and reliable M5F90 achieves a longer service life than a milling cutter with a conventional body. "The tool also consumes a small volume of cooling lubricant and can therefore be described as relatively environmentally friendly," adds Philippe Andre, Global Automotive Application Engineer.

Although the M5F90 is specifically designed for milling thin-walled aluminum components such as transmission housings, it can also machine materials requiring a great deal of work for applications throughout the automotive segment, says Sandvik Coromant. The M5F90 expands the range of aluminum milling cutters for automotive parts and complements the M5B90, M5C90, Coromill Century/590, M5Q90 and M5R90 tool systems.

According to the manufacturer, the M5F90 face milling cutter from Sandvik Coromant offers considerable advantages in automobile production. This two-in-one milling machine not only enables burr-free machining.
