摘要： An improved grinding method and apparatus is advantageously used to sequentially grind the pins of a crankshaft. During the grinding of each crankpin, the pin is supported by a steadyrest. During an initial grinding operation, the crankpins are measured or gauged to determine if they are out-of-round by an amount which is greater than the tolerances for the finished crankshaft and less than a maximum amount. If a crankpin is out-of-round by an amount which is equal to or greater than a maximum amount, the crankshaft is rejected. However, if a crankpin is out-of-round by an amount which is less than the maximum amount and more than the tolerance for a finished pin, a second grinding operation is initiated after the initial grinding operation has been completed. During the initial and second grinding operations, a main drive motor is effective to press the steadyrest against the crankpins. A secondary drive motor is provided to adjust the position of the steadyrest to compensate for the smaller size to which the crankpins are ground during the second grinding operation. The finished crankshaft is removed from the grinding machine only after both the initial and second grinding operations have been completed. When the number of consecutive out-of-round crankpins and/or crankshafts becomes excessive, a control signal initiates shutting down of the grinding machine and the establishing of an alarm to prevent the grinding of a large number of out-of-round crankshafts.
