Influence of Different Pore-Forming Mechanism on Superfinish Grinding Tools

Article Preview

Abstract:

Eight kinds of materials with diverse pore-forming mechanism were added into the ceramic ingredient of superfinish grinding tool with the same amount, and the specimens were prepared and sintered in the same condition. Their pore-forming abilities in the sintered bodies were compared through several performance tests. By measuring the porosity, bulk density, water absorption and flexural strength of these sintered bodies, and observing the SEM images, pore-forming agents with the best working mechanism was identified. It is proved that those pore-forming agents which have pore structures in themselves process the best pore-forming ability, and they can maintain relatively high porosity and high mechanical strength, which is good for the superfinish grinding tools.
