Ceratizit has introduced its PCD MaxiMill SEC12 face-milling cutter to target the machining of crankcases, cylinder heads and other automotive-related components made from aluminium and non-ferrous metals, the interiors of which must remain chip-free. Key to the success of the MaxiMill SEC12 is the design of the insert seat and cutting-insert topology, supported by the coolant pressure, which together create a suction effect that at high speed clears virtually 100% of chips from the workpiece.
Anyone working in engine manufacture will be familiar with this problem: during the conventional face milling of crankcases and cylinder heads, chips fall into the water chambers and get stuck there to such an extent that complete removal by automated washing processes is difficult. Instead, the chips must be removed manually, which involves additional time and costs. And if chips remain, there may be a need to scrap an expensive component.
The new PCD MaxiMill SEC12 (Suction Effect Cutter with 12 mm insert size) eliminates this problem, saving time and cost. Thanks to cutting inserts with a ground-in chip-removal notch and their novel positioning in the body of the milling cutter, the tool develops a suction effect that clears chips away from the part. In addition, the working angle from the flat surface is approximately 30°, which means that hardly a single chip can enter the interior of the component. Coolant flow at the optimum pressure further enhances chip evacuation.
Ceratizit’s MaxiMill SEC12 offers numerous other advantages. One of the most important is its modular design (made entirely of standard components), which enables individual versions to be created for any requirement. The milling cutter consists of a milling adapter in HSK-A63, -A80 or -A100 design, which holds the base body of the face mill.
