IEMCA adds a third Maestro bar feeder to its range

A leading manufacturer of automatic bar feeders for CNC lathes, the Italian company Iemca, has introduced a third model to its Maestro range.

All are designed to maximise productivity on fixed-headstock lathes and offer unattended production around the clock. They are available in the UK and Ireland through sole agent 1st Machine Tool Accessories, Salisbury.

The two existing models can handle round stock up to 100 mm diameter. They are both capable of bar changeover in 31 seconds, as is the new Maestro 52, which is designed for smaller lathes running material up to 51 mm diameter, 42 mm hex and 36 mm square. Bars up to 4.2 metres in length to a maximum combined weight of 100 kg may be loaded.

Among the innovative design features incorporated into the new bar feeder, three have been granted patents. One protects ABACOS (Adaptive BAr COntrol System), a self-adjusting bar clamping arrangement designed to guide the material, damp vibrations and tighten on the pusher, all without changing the guide channel.

Vibration is avoided by another patented feature, the VIBRA-DAMP COLLET with interchangeable inserts. It restricts bar oscillation by reducing their amplitude and lowers bending and torsional stresses on the bar. A third patent has been granted for the HANDYLOQ quick change collet system, which allows manual exchange within three seconds without the need to use tools.

Additional advantages of all Maestro bar feeders are Industry 4.0 data sharing as an option, and a choice of bar loading systems including an UP magazine that allows material to be presented at an ergonomic height. Built-in boxes at the front facilitate access to the electrics, lubrication system and tools, and there is a drawer for storing remnants.

The Maestro is supplied with a modern, 7-inch touch-screen control that has the ability to adjust the magazine automatically for a new bar size, making it quick and user friendly.
