Bar Feeders
With the right bar feeder, the manufacturing process of a CNC lathe can be fully automated.
Based on their operating principles, we distinguish between manual and automatic bar feeders:
- Manual bar feeders do not have a magazine that would automatically feed the bar material to the lathe, this task has to be performed manually.
- Automatic bar feeders, on the other hand, have a magazine that automatically feeds the bar material to the CNC machine.
Prevotex Hungary Ltd. offers reliable and efficient solutions for both bar feeder types.
Our machines are easy to operate and the necessary know-how can be acquired quickly.
Our automatic bar feeders help automate lathes, making the production process more efficient, predictable and reliable.

BAR FEEDER ACCESSORIES

PB 80
Bar material preparation
The PB 80 is the ideal accessory for bar feeders, allowing to machine the end of bar materials. Can be used for chamfering, center hole and diameter turning tasks.

SE-880
Spindle extension
The LNS SE 880 can be used to increase the length of bars that can be loaded with a short bar feeder up to 1600 mm. This way we can use 3 m raw materials if cut in half. This reduces the number of material ends, increases productivity and increases unattended production time. Can be used in the diameter range 8-80 mm.


Spindle reduction tube
When working with bar material, spindle reduction tubes are an essential accessory for lathe machines. They significantly improve the guidance in the spindle, allowing us to use the ideal cutting speed without compromise. Increases productivity, improves tool life and material surface quality. Supplied ready for installation.
