Characteristics of Cast Iron Cutting

⑴ High cutting temperature. This type of material is characterized by high hardness and its machinability is similar to that of hardened steel. HRC is generally 40-60, such as high nickel-chromium chilled cast iron, its HRC is above 60. To cut chips from such a hard material requires a lot of power. In addition, cast iron is a brittle material, and the contact area of the cutting edge is small. The already large cutting force is concentrated on the small cutting edge area, so the unit cutting force is increased, making the cutting process difficult.
⑵ High cutting temperature and fast tool wear. The thermal conductivity of cast iron is worse than that of steel, especially chilled cast iron with a high degree of alloying. Due to the complex metallographic structure, its thermal conductivity is smaller, so its cutting heat is highly concentrated on the narrow cutting edge, which increases the cutting temperature. , thereby reducing the relative hardness of the tool. Then there is Fe3C in cast iron, which has extremely high hardness. It can scratch glass, especially Fe3C which has been solid-solution strengthened by alloying elements. Its hardness is higher, which causes severe groove wear on the tool and greatly reduces the tool life.
⑶ Severe phenomenon of knife hitting and chipping
Cast iron generally contains slag inclusions, pores, sand holes, and cracks, which all make the cutting conditions worse. In addition, the high temperature and high pressure caused by the small contact area of the cutting chips and the uneven force caused by the change of the cutting depth make the cutting The blade is subjected to a large impact load, so in the process of cutting cast iron, it causes frequent chipping of the blade.
