What Tool To Choose For Processing High Chromium Cast Iron?

High-chromium cast iron is a difficult-to-cut material, and the amount of processing left on one side is large, generally 2-5mm on one side. Carbide cutting tools process high chromium white cast iron, the cutting tool wears a lot, cannot carry out continuous processing and frequently replaces the cutting edge, so that the processing efficiency is low and the production cost is increased. Using ceramic cutting tools to process high-chromium cast iron with a unilateral margin of 2mm will cause chipping and breaking problems at the tip of the knife. Ceramic tools have high hardness but high brittleness. When encountering casting defects such as sand inclusions and pores in cast iron (high chromium cast iron), it is easy to break a piece when it belongs to broken cutting. As a result, the tool cost is very high, and the processed products are also unqualified.
The riser of high chromium castings has also become a processing problem, and the performance requirements for cutting tools are also very high. The performance of the tool should have high hardness, strong impact resistance, and good toughness so that there will be no phenomenon of breaking the knife and jumping blocks during tool processing.
