Clamping fingers or finger collet mounted in automatic machines, single and multi-spindle automatic lathes, CNC lathes with movable tailstock, CNC lathes with fixed head, counter-spindle, pick-up spindle, are components that act as levers, allowing the bar puller to perform a longitudinal stroke in the axis, which allows clamping of the collet on the bar. In the case of using draw collets, Clamping fingers or finger performs the retraction movement of the rod on which the collet is mounted, which, by acting on the closing cone, allows clamping of the bar. If the collet is clamped in compression, the collet is held on the length by a nut that prevents axial movement. Through the movement of the bar puller, it pushes the conical sleeve against the nut, causing the collet to clamp. The adjustment of the front nut allows adjusting the clamping force of the bar. The same operating method is used for all closing systems that use Chuck lever. This technology is applied for the engagement or disengagement of mechanical clutches used on dated but still functioning automatic machine tools, for stopping or rotating the main spindle or pick-up spindle. The manufacture of these components, even though it may seem simple, is actually complex because they have to perform the function of opening and closing the collet with a significant closing force for thousands or hundreds of thousands of times. Special steel is used, undergoing various heat treatments also in different areas of the finger. It is considered a wear part for extraordinary maintenance. Its lifespan depends greatly on how the hammer is made.
