| Abstract: | V-typed steel guide are the key part in high precision omnipotent tool grinder. After heat treatment, during the grinding process of the guide, cracks are appeared on the surface of most guide. Macroscopic analysis, metallography, hardness testing and heat acid corrosion experiments have been conducted. The results showed that these surface cracks are resulted from improper grinding. Prevention measure was proposed. |
