The machine frame is manufactured form high tensile cast iron, stress relieved for maximum rigidity and long time accuracy. The frame structure is designed by means of "computerized analysis".It provides optimum design for frame strength and strain. The frame is tightened by blots, incorporating with hydraulic preload on structure for giving added rigidity. DYNAMIC AND STATIC ACCURACY:
Extended and over-sized slide guide column, combined with no-backlash axial bearing, that ensuying high accuracy while in off-punhing operations. The preloaded bo
An ultra rigid H frame structure reduces deflection to less than 1 mm. Patented 9-linkage mechanism maintains a unique 44 ¢X stoppage of slide at B.D.C., enabling precision cold forming e.g. coining & sizing processes. Improved knuckle driving mechanism that never moves to full perpendicular position and eliminates die sticking near B.D.C. Very rigid slide and bed creating very low deflection which is less than 1/33000''.
