PURPOSE:To continuously effectuate different finishings with tools, by moving the selected tool forth onto a machined surface and moving the other tools back. CONSTITUTION:Three pairs of tools 26a and 26d, 26b and 26e, 26c and 26f for performing different finishings are provided on a disc-like base 1 along its circumference so that the tools can be selectively moved back and forth by electromagnets 14a-14f or the like perpendicularly to the machined surface of a workpiece 36. To start the finishings, the reflectivity of the machined surface as to light is detected by a photoelectric discriminator or the like to select the necessary tools first. The base 1 is then turned to cause the selected tools to face the machined surface. At the same time, the other tools are all moved back to the base 1 by the electromagnets or the like. After that, a table 40 is driven back and forth to perform the desired finishing. |
