The 034.006 bar pusher collet for LNS - TRYTON bar feeder is a technical component intended for automatic bar feeders installed on automatic lathes, CNC lathes and sliding headstock CNC machines. The product is designed with M4 thread and outside diameter= 6 mm, a configuration suitable for bar feeding systems where compact dimensions, accurate grip and continuous feed during the production cycle are required.

The function of the bar pusher collet is to connect the feeder pushing device to the bar being machined, keeping the material correctly guided while it advances towards the spindle or clamping area of the machine tool. During production it helps stabilise bar movement, reduce unwanted backlash, vibration and misalignment, and support correct management of the final remnant. A correctly sized collet helps the technician achieve smoother feeding, better cycle repeatability and a lower risk of errors caused by dragging, stop position variations or loss of centring.

The component must be selected according to the feeder model, machine type, bar diameter, material profile and operating conditions. Bar pusher collets can be supplied for round, hexagonal or square bars; for shaped profiles, grinding is carried out according to the corner dimension, so that the coupling matches the actual geometry of the material. This aspect is particularly important in precision machining, where correct contact between collet and bar affects stability, feed consistency, noise level and process reliability.

For correct application it is recommended to check the M4 thread, outside diameter= 6 mm, compatibility with the LNS - TRYTON feeder and the condition of the contact surfaces. During preventive or extraordinary maintenance, technicians should inspect wear, residual elasticity, possible deformation, chip build-up, signs of ovality and transmission backlash. A worn or unsuitable collet can cause irregular feeding, difficulty in remnant ejection, vibration and bar feeding defects that may affect machining quality.

This item is suitable for machine shops, production departments, manufacturers and users of automatic lathes, maintenance technicians, quality control managers, process engineers and technical laboratories requiring professional spare parts for bar feeders. Tadaah offers the bar pusher collet as a component designed to support production continuity, with a technical approach focused on correct spare part selection, mechanical compatibility and optimisation of bar feeding in industrial machining applications.
