Cutting Tool Materials

Three grades of nodular cast iron (60, 80, and 100) were tested to determine the tool life of carbide and ceramic cutting tool materials. Tool life for all tools was much greater for grade 60 than for 80 and 100. Cast iron cutting grade carbide K6 was superior to steel cutting grade K3H, and at high speeds the ceramic was superior.

Cutting Tool Materials

The development status of self-lubricating tool materials was reviewed in the present study, as well as the five basic types of self-lubricating tool and the current situation of nanometer materials in ceramic cutting tool. Based on these, the design idea of the functional gradient materials and nano-micro composite materials was introduced into the self-lubricating ceramic cutting tool materials, in order to develop new self-lubricating ceramic cutting tool materials with both good mechanical and frictional properties.

Cutting Tool Materials

Al2O3/TiC ceramic tool materials with the addition of solid lubricants such as BN and CaF2 were produced by hot pressing. Effect of the solid lubricants on the microstructure and mechanical properties has been studied. Results showed that AlN phase resulted from the reaction of Al2O3 with BN was formed in Al2O3/TiC/BN composite after sintering. Significant micro-cracks resulted from the residual stress owing to the difference in the thermal expansion coefficient were found on the polished surface, and caused large mechanical properties degradation. While Al2O3/TiC/CaF2 composite showed higher flexural strength, fracture toughness, and hardness compared with that of Al2O3/TiC/BN composite owing its porosity absent and finer microstructure.

The α-SiAlON ceramic cutting tool insert is developed. Silicon nitride and additives powders are pressed and sintered in the form of cutting tool inserts at temperature of 1900 oC. The physics and mechanical properties of the inserts like green density, weight loss, relative density, hardness and fracture toughness are evaluated. Machining studies are conducted on grey cast iron workpiece to evaluate the performance of α-SiAlON ceramic cutting tool. In the paper the cutting tool used in higher speed showed an improvement in the tribological interaction between the cutting tools and the grey cast iron workpiece resulted in a significant reduction of flank wear and roughness, because of better accommodation and the presence of the graphite in gray cast iron. The above results are discussed in terms of their affect at machining parameters on gray cast iron.
