PURPOSE:To perform a proper grinding work by composing it so as to automatically decide the optimum feeding speed of the material to be ground according to the input of various grinding data. CONSTITUTION:A data input device 31 inputting the data of the material to be ground, a grinding belt gage data, grinding allowance data and the peripheral speed data of a grinding belt, is provided and the optimum feeding speed of the material to be ground is decided by an arithmetic device 32 based on the input data received from this data input device 31. A grinding work is executed on the material to be ground by a wide belt sander 10 at the optimum speed decided by this arithmetic device 32. |
