3J' is pivotally supported by a shaft (4) so as to be tiltable, and can be fixed at an appropriate tilting position by a clamp grip (5). In the drawing, (6) indicates a rotary cylinder that is rotatable within the housing (3), and the cylinder (6)
is connected to a removable pneumatic rotary tool (7) via a gear mechanism (8) and is driven and rotated by the tool (7) K, and the inside thereof further includes a p-tally valve (9) at the top. through which an external source of pressurized air was seated, thus allowing the interior to be maintained at the appropriate pressure by channeling air from the shell source. In the drawing, αI indicates a vertically movable screw inside the cylinder (6): 10, and the nuclear rod α
It is of the type that engages with the cylinder (6) through the ut and rotates with it, and has a whetstone 7 lange 0 connected to it through the universal joint α3 at its lower end, and furthermore, the 7 lange 0 is connected to the cylinder (6) through the universal joint α3. A plurality of grindstone pieces A4, for example three pieces, are provided on the lower surface of the grindstone so as to be tiltable in the upper movable hook against the respective springs α9.

し得られ、これに無理を生ずることがない。To explain its operation, in order to process a mold curved surface or other workpiece a, first the rotary cylinder (6) is rotated and pressurized air is introduced into the cylinder (6). For example, when this is made to straddle the upper surface of the core workpiece a as indicated by the chain line in Figure 1, each grindstone piece a4 rotates with the cylinder (6) while In other words, each grindstone piece α is pressed against the workpiece a with an appropriate pressure and rotates once to finish the workpiece. Thus, by moving this along the workpiece aK, the entire surface of the workpiece aK can be machined, but during such operation, each grindstone piece α
4 is allowed to tilt toward the upper movable hook against the spring α9, and is also allowed to oscillate in the flange 0 of the whetstone 7, thus freely following changes in the curved surface of the skeleton work 1. This can be achieved without any unreasonableness.

る等の効果を有する。In this way, according to the present invention, it is sufficient to simply place the grinding wheel over the workpiece and move it along the workpiece, making the work simple and highly efficient. The grinding wheel piece is pressed against the workpiece by keeping the pressure constant at all times to improve machining accuracy, and the grinding wheel piece also allows tilting of the upper movable hook against the spring and neck vibration due to the universal joint. It has the effect of well following changes in the curved surface.
