  • annealing

    annealing

    Softening a metal by heating it to and holding it at a controlled temperature, then cooling it at a controlled rate. Also performed to produce simultaneously desired changes in other properties or in the microstructure. The purposes of such changes include improvement of machinability, facilitation of cold work, improvement of mechanical or electrical properties and increase in stability of dimensions. Types of annealing include blue, black, box, bright, full, intermediate, isothermal, quench and recrystallization.

  • normalizing

    normalizing

    Heating a ferrous alloy to a temperature above the transformation range and then cooling in air to a temperature below the transformation range.

  • payload ( workload)

    payload ( workload)

    Maximum load that the robot can handle safely.
