PURPOSE:To improve processing accuracy and working efficiency in honing work, by measuring inside diameters of the processed hole, and according to the measured diameters, by providing the abrasive tool with a higher rotating speed and a lower stroking speed where the thickness to be honed is larger, and with a higher rotating speed and a lower stroking speed where the thickness to be honed is smaller. CONSTITUTION:When a switch 32 is turned on, an output signal from a regulating circuit 31 is amplified by the amplifier 33 and fed to a control circuit 34, and a control signal corresponding to the above output signal is supplied from the control circuit 34 to a flow control valve 13. The valve 13 is adapted so that its opening is made smaller by the signal where the thickness to be honed is larger, thereby restricting the oil flow from a direction control valve 11 for slowing down the speed of stroke means 4, and its opening is made larger where the thickness to be honed is smaller, thereby allowing a larger oil flow to speed up the stroking speed. And when a switch 35 is turned on, an output signal from the regulating circuit 31 is amplified by an amplifier 36 and sent to a control device 37, and a control signal according to the above output signal is applied to a motor 15 thereby to increase the number of revolutions where the thickness to be honed is larger and to decrease the same where the thickness to be honed is smaller. An improvement of processing accuracy and efficiency can thus be achieved. |
