The 034.013 bar pusher collet for LNS - TRYTON bar feeders is a technical component designed for automatic bar feeding systems installed on automatic lathes, CNC lathes and sliding headstock machines. Its purpose is to connect the feeder pusher correctly to the bar being machined, ensuring regular feeding, stable contact and consistent positioning of the material during turning, pick-off, parting-off and serial production operations. This version has an M6 thread and a 12.5 mm outside diameter, making it suitable for compatible LNS - TRYTON feeder configurations and for applications requiring compact dimensions, accurate coupling and reliable axial movement of the bar.

The main function of the bar pusher collet is to guide and push the bar towards the spindle or clamping area of the lathe, reducing transmission play, misalignment and vibration that could affect cycle stability. An incorrect grip, unsuitable diameter or worn threaded connection can cause feeding errors, variations in part length, marks on the material, abnormal noise or difficulty when removing the final bar remnant. For this reason, the correct collet must be selected by checking the feeder model, connection type, M6 thread, 12.5 mm outside diameter and the profile of the bar to be machined.

This product is intended for turning companies, mechanical workshops, automated production departments, machine tool builders, maintenance technicians, tool setters, process engineers and quality control laboratories that need to keep the bar feeding system efficient. The collet can be supplied for round, hexagonal or square bars. For hexagonal or square profiles, the internal shape is ground according to the corner dimension, improving contact on the profile and reducing the risk of uncontrolled rotation or uneven gripping during feeding.

During installation, the feeder seat should be cleaned carefully, the condition of the thread should be checked and the collet should be verified for smooth movement without sticking. Chips, dried oil residues or small deformations can affect alignment and generate form errors, eccentricity or premature wear. Before starting the automatic cycle, it is advisable to perform a manual feeding test, check the coaxiality between feeder and spindle, verify the working height of the bar and make sure there is no interference with bushings, guides or clamping systems. Correct adjustment reduces machine downtime, improves cycle repeatability and protects both the bar and the internal components of the feeder.

The bar pusher collet is a small but essential element for the quality of the feeding process. In continuous production it helps keep the bar stable during the final material section, supports the removal of the bar remnant and allows safer cycle management on solid materials, profiled bars and small diameters. To obtain the best result, the component should be matched to the actual bar diameter, material tolerances should be considered, wear, elasticity and rubbing marks should be inspected regularly, and the collet should be replaced when gripping is no longer uniform. Tadaah offers this component as a technical spare part for professional users who need a precise, compatible and production-oriented solution.
