ブピストン型の部分の摩擦損失は無視できる）。If the cutting tool of the sub-floating device 4 is mounted vertically, chips can be easily removed from the cutting edge. By holding the cutting tool of the main floating device 2 horizontally, when the radial component of the cutting force during the preceding cutting of the sub-floating device fluctuates, the influence of the fluctuation can be prevented from reaching the main floating device, and , the main floating device 2 can be retracted without being hindered by the secondary floating device 4. The direction of the surface of the workpiece that has been cut is determined by the gauge 1.

The hydraulic cylinder 16 rotates, and this rotational force is maintained constant by adjusting the pressure in the working chamber of the hydraulic cylinder 16. The rod 18 of the hydraulic cylinder 16 also pushes the sleeve 17 and the cage 14 via the spring 19, which cage 14 moves the polishing roller 13 until it comes into contact with the guide @28. The spring 19 is for improving the sensitivity for controlling the polishing roller deformation force of the transducer, and this rI
! The polishing roller creates a deforming force and has the effect of canceling out the effect of friction loss of the seal part of this hydraulic cylinder on the output of the hydraulic cylinder (friction loss of the paired sleeve-piston type part can be ignored) ).

ルをくり返す。The floating device moves to the left in the figure until the polishing roller 13 engages the workpiece. The time to engage the workpiece is the point at which the rotation of the spindle and the axial feed are decoupled and the polishing roller engages the workpiece being machined. Upon completion of the cutting step, the r2 drive is returned to its initial position on the right side of the figure, the workpiece is removed, and the next workpiece is installed. This processing cycle is repeated.

にするからである。The apparatus based on the present invention can improve the cutting precision of the workpiece. The reason for this is that the sub-floating device performs the preliminary cutting on the surface of the workpiece in preparation for facilitating finishing processing by the subsequent main floating device;
After finishing processing by the main floating device, the remaining paths on the surface of the workpiece are smoothed by pressing the polishing roller against the surface of the workpiece with a constant force, thereby making the stress on the workpiece uniform. It is from.
