Bar feeder for CNC Lathes
In the world of modern machining, numerically controlled (NC) lathes occupy a central position. These machines, renowned for their precision and productivity, require a continuous flow of bars to operate at optimum efficiency. Without a regular supply, downtime accumulates and profitability plummets. This is where NC lathe bar feeders, also known as automatic bar feeders, come in. This equipment has become essential for manufacturers, plant managers and bar turners looking to maximise their performance. In this article, we offer a complete overview: definition, operation, different types of bar feeder, leading brands and advice on choosing the right equipment.
Over and above these technical aspects, it is essential to be supported by an experienced professional. As a recognised expert in the sale and rebuilding of machine tools, SAMO puts its know-how at the service of manufacturers to offer bar feeders that are perfectly compatible with their production environment.
What is an NC lathe bar feeder?
1.1 What is a bar feeder?
A bar feeder is a device designed to automatically feed metal bars to an CNC lathe. It enables the machine to machine continuously without repeated manual intervention. In a production workshop, this equipment saves considerable time and reduces downtime associated with bar reloading. The integration of a bar feeder therefore represents a major lever for improving the rate and regularity of machining.1.2 How a bar feeder works
The principle is simple: the bar feeder automatically feeds a new bar into the lathe spindle as soon as the previous one is finished. This process is synchronised with the production cycle of the NC lathe, guaranteeing perfect continuity. The most recent models, known as automatic bar feeders, incorporate intelligent systems capable of handling different bar diameters and lengths with great reliability.What are the different types of bar feeder?
1. Automatic bar feeders
Automatic bar feeders represent the top of the range. They operate fully automatically, without human intervention. They offer exceptional precision, remarkable productivity gains and a drastic reduction in downtime. These models are particularly well suited to high-volume production, where every minute counts.2. Semi-automatic bar feeders
More affordable in terms of cost, semi-automatic loaders require partial human intervention (for initial loading, for example). They represent a good compromise between performance and budget, and are perfectly suited to medium-sized workshops looking to increase their efficiency.3. Mechanical loaders
Simpler and more economical, mechanical loaders often operate manually. Although they are less efficient than automatic solutions, they are useful for small production runs or one-off requirements. Their main advantage is their low cost and ease of maintenance.What are the advantages of bar feeders?
There are many benefits to adopting a bar feeder in an industrial workshop:- Optimised productivity: continuous machining without interruption.
- Improved safety: less manual handling, so fewer risks.
- Reduced downtime: automated bar changeover.
- Flexibility: ability to handle bars of different diameters and lengths.
Overview of the main bar feeder brands
Iemca bar feeders
The Italian brand Iemca is considered the world leader in automatic feeding systems for NC lathes. Its catalogue covers a wide range of needs, from small to large production runs, with models renowned for their reliability and precision. Choosing Iemca means investing in long-term performance.LNS bar feeders
LNS, a Swiss manufacturer, is also a global benchmark. Its bar feeders stand out for their robustness and their ability to adapt to the requirements of high-performance workshops. With an international presence, the brand enjoys a solid reputation in the bar turning sector.Other brands to know
Other players such as Giovanni Cucchi and SAMECA also offer interesting solutions. By comparing several brands, you can select the bar feeder best suited to your specific needs in terms of output, budget and compatibility with your machinery.How do you choose the right bar feeder for your NC lathe?
To make the right choice, a number of criteria need to be taken into account:- Type of production (large or small series)
- Diameter and length of bars used
- Level of automation required
- Available budget and expected return on investment
Over and above these technical aspects, it is essential to be supported by an experienced professional. As a recognised expert in the sale and rebuilding of machine tools, SAMO puts its know-how at the service of manufacturers to offer bar feeders that are perfectly compatible with their production environment.
