Types of Cuttimg Tool Materials
There are different cutting processes done on varying conditions. Depending on the cutting conditions and the requirements of the respective cutting tool , it is important that they are of the right properties. The type of material selected for a specific application depends on what is being machined. Here is a classification of these materials. Carbon Tool Steel This is one of the inexpensive metal cutting tools common in low-speed machining operations. These carbon steel cutting tools are constructed with a composition of 0.6%-1.5% carbon and small amounts, less than 0.5%, of Si and Mn. To enhance the hardness, other materials such as V and Cr could also be added. Carbon tool steels are preferred because they are abrasion resistant and can maintain the cutting edge for a long period. However, they lose their hardness when temperatures reach 250 °C. This means that they are not good for high-temperature operations. Commo...
