Chip Spitting When it comes to chips and milling, size does matter
Adding a technique to split chips helps cutting inserts increase their productivity while improving the machining process, according to cutting tool supplier Iscar.
In chip splitting, a wide chip is divided into small segments that improve chip evacuation and handling. Chip splitting reduces cutting forces and power consumption and leads to less heat generation during milling. In addition, the chip-splitting action strengthens vibration dampening.
Split the chips to boost a range of milling properties
Cutting-tool supplier Iscar said several of milling cutter inserts now feature a cutting edge with a chip-splitting effect.
Better chip evacuation, lower cutting forces and heat, increased resistance to vibrations – these key features provide the best advantages for rough milling with the use of extended flute or porcupine-style cutters, the company said.
Indeed, the cutting blade of such cutters is composed of a set of consecutively located inserts. Usually the cutters work with high depths of cut and can remove large volumes of material. Consequently, the segmentation of the produced chips is highly important for their effective transportation through the chip gullets of a cutter.
