The 210E- SH10 feed finger collet is a technical component for automatic bar feeders installed on automatic lathes, CNC lathes and Swiss-type CNC machines. Its function is to grip, guide and push the bar during the feeding cycle, keeping the material correctly aligned with the feed line and supporting continuous turning operations. It is a quick-change collet for FMB, TRAUB, HAGENUK, IEMCA, ROBOBAR, LNS, SAMECA, MINISPRINT and MINITURBO bar feeders, designed for production departments where feeder reliability and repeatable movement directly affect part quality and machine productivity.

The product works as the connecting element between the feeder pushing system and the bar to be advanced. During the cycle, the collet closes on the material, transmits the feed movement and allows the bar to reach the position required by the machine program or mechanical cycle. A correctly selected feed finger collet reduces slipping, vibration and misalignment, especially on Swiss-type lathes, where bar stability and smooth feeding are essential to maintain dimensional accuracy, surface finish and tool life. The quality of the contact with the bar is also important when managing the final bar remnant, because unstable pulling or pushing can cause impacts, positioning errors or interruptions in the automatic cycle.

The choice of the collet should consider the bar feeder model, bar type, nominal diameter, material geometry, remnant length, feed speed, spindle-line height, alignment between feeder and lathe, and backlash in the pushing transmission. For accurate operation, the collet should match the real bar diameter and should be checked for wear on the gripping areas, abnormal elastic deformation, burrs, irregular contact marks or loss of concentricity. Insufficient gripping can cause slipping and non-repeatable feeding, while excessive closing force can mark the material or affect the smoothness of movement. During preventive maintenance, it is also useful to check the bushing, pusher tube, guide systems, axial settings and feeder height in relation to the machine axis.

In industrial applications, this collet is used in machine shops, automated production departments, bar turning companies, manufacturers of precision components, maintenance teams for automatic lathes and technical laboratories that need reliable feeding continuity over repetitive cycles. It is suitable for production environments where the bar must advance in a controlled way, without vibration-induced form errors, loss of position or transmission backlash that could compromise the cycle. The collet is not a measuring instrument in itself, but its correct use requires accurate dimensional and geometric checks, because bar diameter, working height, coaxiality, guide wear and feed-force adjustment directly influence the precision of the complete system.

For technicians, engineers, maintenance specialists and quality control managers, the 210E- SH10 feed finger collet is a strategic spare part for keeping the connection between bar feeder and lathe efficient. When replacing it, the code, product family and compatibility with the installed feeder should be checked, while also ensuring that the quick-change system moves without sticking and that the opening and closing action is clean, free and repeatable. Regular maintenance, including seat cleaning, wear inspection and alignment checks, helps reduce machine downtime, production scrap, feed errors and gripping-quality problems on the bar.
