PURPOSE:To improve the cutting rigidity by engaging a piston supported in slidable ways along the direction of the rotary shaft line of a dividing table on all immovable side directly with a flange part in free separation and attachment, thus permitting the firm clamp. CONSTITUTION:A clamp ring 1 is installed onto the undersurface of a dividing table 10 in concentric form with a rotary shaft and fixed by a bolt 6 screwed with a tapped hole 5. A projecting groove 7 is formed onto the outer periphery in the thick body part on the center side of a machine body 11, and a piston 8 is formed from a ring member and engaged with a recessed groove 7 so as to surround said recessed groove 7, and a cylinder chamber 9 is formed. In other words, the piston 8 is fitted into the recessed groove 7, and supported in slidable ways into the recessed groove 7 along the direction of the rotary shaft line of the dividing table 10. The passages 18 and 19 for the introduction and discharge of the pressure medium into the cylinder chamber 9 are drilled on the thick body part of the machine body 11, and communicate to a pressure source and selecting machine. |
