  • Tool pot for tool magazine
    Patent number: 6620083
    Abstract: A tool pot used for a tool magazine of a machine tool to removably hold a tool is disclosed. A main body of the tool pot is constructed a cylindrical wall defining a holing aperture for holding the tool, end ribs formed at opposed ends of the cylindrical wall and a plurality of longitudinal ribs formed between the end ribs on the outer periphery of the cylindrical wall. And the main body is integrally molded from a glass-fiber reinforced thermoplastic resin material such as crystalline nylon-type resin. Therefore, the tool pot has high wear resistance and light weight, and it can be recycled.
