Near Net Size

With more and more rough precision manufacturing, automotive components rough shape and accuracy increasingly closer to the finished product size, and this is the so-called "near net Size" (the so-called NNS, NearNetShape). Achieve "near net size" rough, different from the traditional rough forming technology, the precision of these rough shape, the size of high accuracy, precision and good-shaped surface roughness, allowance is very small. This rough near the size of the net, to bring about a series of processing effects, and the tool, the cutting force is the need of small and sharp cutting edge. In recent years, many tool maker unveiled more than ever suitable for a small cushion for processing tool, and its main feature is a sharp tool, the better the wear resistance of the tool. Cutting Edge strength in the balance at the same time raise as much as possible of a common tool sharp choice. For example, a high mountain tool launched MF5 chip breaking Groove is a near net size for processing tool products. It uses a new open design, it has a semi-sharp cutting edge, chamfering was divided into two sections, namely +5 �� and +10 ��, these subparagraphs increase in the width direction, and at the same time is variable angle more small (to a depth of cut is larger and better intensity), the former angle is 17 ��. This semi-sharp cutting edge in the design of processing can reduce cutting force, than the traditional "all sharp" blade of a higher intensity.
