The 034.010 bar feeder push collet for LNS - TRYTON bar feeders is a professional component designed for bar feeding systems installed on automatic lathes, CNC lathes, sliding headstock lathes and continuous production machines. Its M5 thread and 10 mm external diameter make it suitable for compact pushing units where grip accuracy, alignment with the bar axis and stable feeding are essential to keep the machining cycle regular.

The function of a bar feeder push collet is to connect the feeder pushing system to the bar being machined, transmitting the feed force in a controlled way during advancement towards the spindle or the machine collet. Depending on the configuration of the feeder and lathe, the component also supports management of the remaining bar end, helping guide the material correctly and reducing the risk of irregular feeding, vibration, impacts or loss of grip.

This item is intended for technical use in turning departments, machine shops, bar machining production, ordinary maintenance and extraordinary maintenance of automatic bar feeders. It is a simple-looking but critical component for process quality: an unsuitable, worn or incorrectly matched push collet can cause feeding errors, misalignment, marks on the material, problems with remnant ejection, machine stoppages and instability when machining small parts.

Push collets can be supplied for round, hexagonal or square bars. For hexagonal or square profiles, grinding is carried out according to the corner dimension, so that the collet matches the actual section of the material. This is important when machining profiled bars, because correct contact between collet and bar provides more uniform pushing action and limits unwanted play during feeding.

When selecting the component, it is advisable to check the bar feeder model, the connection type, the M5 thread, the 10 mm external diameter and the geometry of the bar to be machined. To achieve stable production continuity, the collet must fit correctly into the pushing unit, show no local deformation or wear, and grip the material properly without excessive force. Too much clearance can generate transmission play and irregular feeding, while an overly tight grip can mark the bar or increase friction.

During maintenance checks, operators should verify the cleanliness of the seat, the absence of chips or residues, the condition of the thread, concentricity with the pushing axis and the behaviour of the material during the first feeding strokes. Small form errors, burrs on the bar, inconsistent tolerances or imperfect bar geometry can affect the performance of the collet and the precision of the feeding process. For this reason, the component should be assessed together with the complete system, including bar feeder, guide tube, pusher, spindle, machine collet and machining parameters.

The LNS - TRYTON push collet is intended for technicians, maintenance engineers, process engineers, manufacturers, quality control departments and turning professionals who need a technical spare part consistent with the installed system. Correct selection improves feeding regularity, reduces machine downtime, protects the material and helps optimise productivity on automatic and CNC lathes.
