When milling wing supports made of highly abrasive austenitic chromenickel steel, milling cutters at ystral gmbh fail after just one component. A solid carbide milling cutter from G\u00fchring ensures the necessary process reliability thanks to its two-fold tool life.

Chipped coatings and high cutting edge wear \u2013 when milling wing supports, milling cutters at ystral gmbh quickly reached their limits. \u201cAfter one component, it was over\u201d, recalls Deputy Production Manager Marco Wissmann. \u201cThat\u2019s simply not a reliable process.\u201d This high level of wear is due to the material to be machined: 98 percent of the components manufactured on the state-of-the-art milling machines of this attractive employer in the Markgr\u00e4flerland region are made of stainless, austenitic chrome-nickel steel.<\/p>\n

G\u00fchring milling cutter puts an end to chip nests<\/h2>\n

Confidently, Oliver Mattes offered ystral to start a trial with a G\u00fchring milling cutter \u2013 and had just the right one in mind: the RF 100 5 Speed. \u201cThe speed is optimal for this application because it is particularly strong in V4A\u201d, says Oliver Mattes. The solid carbide milling cutter from G\u00fchring ensures extreme metal removal rates even in difficult-to-machine materials with the highest process reliability. With five teeth and a large helix angle of 38\u00b0, it is perfect for roughing. The RF 100 5 Speed is also equipped with a 9\u00b0 back rake angle and offset chip breakers \u2013 a major advantage, as Wissmann explains: \u201cWhen we used tools without chip breakers, chip nests were constantly formed in the machine as chip removal was not possible.\u201d The machine had to be stopped constantly for chip removal. \u201cWe save this time now because the much shorter chips are simply flushed out\u201d, says Wissmann happily.<\/p>\n

Overcoming all the hurdles<\/h2>\n

The wing supports with 200 to 230 mm diameter are manufactured as turned parts. The wings, which later serve to disperse the liquids in the tank, are then milled out on the milling machine. This milling operation is carried out in the trochoidal process. The milling cutter moves in an elliptical circular motion and plunges into the material with its entire cutting edge length. This highly dynamic milling technology means that process reliability, tool life and time savings are particularly high \u2013 and the RF 100 5 Speed is perfect for this, as it enables up to 10 percent lateral infeed. The contour is then finished with the same tool. The surface quality plays an important role here, as the finished wing supports must have an Ra value of 0.8 mm.<\/p>\n

Working together to find a solution: Marco Wissmann (ystral) and Oliver Mattes (G\u00fchring).<\/p>\n

In terms of cutting values, G\u00fchring is guided by the previously used tool of a competitor. Marco Wissmann explains: \u201cThe average values set the times that we have to keep achieving, because we didn\u2019t want to work slower.\u201d The production manager explains that the count began immediately: \u201cOld milling cutter out, new one in; once it is up and running, we buy it.\u201d After extensive tests by Tim Zorawski and Andreas Krumnack, the result was convincing.<\/p>\n
