<p>A machining device has a base on which a workpiece is placed, a supporting column stood on the base, a supporting member liftably installed on the supporting column, a hollow motor supported, by the supporting member, above a region where the workpiece is placed, a hollow spindle connected to the motor and extending downward, a chuck fixed to the lower end of the spindle, a tool having a column-like shank and supported by and fixed to the chuck at the side face of the shank, a supersonic vibration-applying member provided, in a contacting manner through a lubrication layer, on the shank of the tool, and a load-applying member for pressing the supersonic vibration-applying member to the top surface of the shank of the tool. The construction of the machining device is simple, and capable of performing machining by applying, with a simple method, supersonic vibration to various kinds of tools.</p> |
