The 036.101 bar feeder collet for IEMCA bar loaders is a technical component designed for automatic bar feeding systems installed on automatic lathes, CNC lathes and sliding headstock lathes. The M6X0.75 thread and 10mm outside diameter make it suitable for applications where the pushing system must be accurately connected to the bar being machined, maintaining feeding continuity, gripping stability and correct material control during production.

The bar feeder collet works as an interface between the bar loader and the bar. During machining, it helps guide the material towards the spindle or gripping area of the machine, supporting consistent feeding and repeatable production. A correctly sized collet reduces transmission play, vibration, slipping and misalignment that may affect the quality of the finished part, process stability and wear on the mechanical components of the bar loader.

This item is intended for machine shops, production departments, machine builders, maintenance technicians and professionals working with IEMCA automatic bar loaders. Dimensional control of the thread, outside diameter and bar coupling is essential to ensure correct installation and stable operating behaviour. Before installation, it is advisable to check the condition of the push rod, the cleanliness of the seat, the absence of burrs, deformation or chip residues and the compatibility with the bar profile being used.

Bar feeder collets can be supplied for round, hexagonal or square bars. For hexagonal or square profiles, the grinding is carried out according to the corner-to-corner dimension, so that the contact is consistent with the real geometry of the bar and the grip is suitable for the material section. This is particularly important in precision machining, where shape errors, ovality, irregular profiles or uncontrolled tolerances can cause uneven feeding, vibration or difficult bar movement.

For correct use, the collet should be replaced when loss of elasticity, uneven gripping, wear marks on the contact area, deformation or difficulty maintaining bar feed are detected. During preventive maintenance, it is recommended to check the coaxial alignment between bar loader, bar and spindle axis, the correct height of the loader relative to the machine, the absence of abnormal play in the push line and the smooth passage of the bar. Accurate adjustment improves precision, cycle continuity and production reliability.

The IEMCA bar feeder collet is therefore a professional solution for companies, technicians, engineers and laboratories requiring a dedicated component for material handling on bar turning machines. The choice of the collet must always be linked to the bar loader model, thread type, outside diameter, bar shape and machine operating conditions in order to obtain a correct coupling and reduce downtime, feeding errors and production quality issues.
