  • Publication number: 20100257981
    Abstract: A pipe-end processing tool and a pipe-end processing system for it. A guide roller is used which runs along the inside peripheral surface of a pipe to be processed and as a result keeps an implement designed to machine an outer edge bezel of said pipe at a constant radial distance from the inside peripheral surface. As a result residual wall thicknesses constant over the full pipe periphery are generated even when the pipe is not rigorously circular, for instance illustratively oval.

  • Patent number: 7052215
    Abstract: A cutting tool with a sensor according to the present invention includes an electrically conductive substrate, an insulation film provided on a surface of the electrically conductive substrate, and a sensor circuit of an electrically conductive film provided on the insulation film. The insulation film includes two consecutive insulation layers. Even if the plural insulation layers each have defects such as cracks and pinholes which possibly impair the insulation property impair the insulation film, the defects present in the plural layers are unlikely to be continuous. Therefore, the insulation film has an improved insulation reliability, thereby ensuring proper function of the sensor circuit in the cutting tool.
