As an essential accessory for lathes and machining centers, bar feeders significantly streamline production by automatically loading materials into machines. Several key factors must be considered to ensure a worthy investment.
Compatibility: A crucial first step is to verify the compatibility of the bar feeder with your existing machinery. It should match the machine's make, model, and bar diameter requirements.
Bar Diameter and Length: Bar feeders handle various bar sizes, so ensure the feeder suits your operations. Double-check both the maximum and minimum diameter and length that the bar feeder can support. It's also crucial to consider whether you need a short or long bar feeder based on your production requirements.
Condition: The condition of the used bar feeder directly impacts its performance. Request detailed photos and if possible, videos of the equipment in operation. Examine for any signs of excessive wear, corrosion, or other potential issues.
Feed Rate: The feed rate determines how quickly the bar feeder can supply material to the lathe. Depending on your production volume and speed requirements, verify the bar feeder's feed rate.
Maintenance History: Regular maintenance ensures the longevity of a bar feeder. Ask for the equipment’s service log to review its maintenance history. Well-maintained machinery will often run more reliably and efficiently.
Brand Reputation: Certain manufacturers are known for their quality and reliability. Do some research on the brand and model of the bar feeder you intend to purchase.
Safety Features: Safety is paramount in any production setting. Confirm that the used bar feeder has intact safety features, such as emergency stop controls and safety guards.
By checking these crucial points before purchasing a used bar feeder, you can ensure the machine will meet your operational needs while providing good value for your investment.

This includes the maximum and minimum diameter and length it can support. Depending on your production needs, you might also need to consider whether you need a short or long bar feeder.
Feed Rate: The speed at which the bar feeder supplies material to the lathe is a crucial factor. If you have high-volume or high-speed production requirements, ensure the bar feeder's feed rate is up to the task.
Physical Condition and Maintenance History: The current condition of a used bar feeder can greatly affect its performance and longevity. Always request detailed photos and, if possible, videos of the equipment in operation. Look for any signs of excessive wear or other potential issues. It's also beneficial to review the service log or maintenance history of the machine. A well-maintained machine is often a more reliable machine.
Manufacturer: Some manufacturers have a reputation for producing high-quality, long-lasting bar feeders. Notable names include Iemca, LNS Group, FMB Machinery, Edge Technologies, Lexair/OML, and Haas Automation. Do your research to understand the strengths and weaknesses of each brand.
Safety Features: In a professional setting, safety is paramount. Ensure the used bar feeder has all necessary safety features intact, such as emergency stop controls, safety guards, and any other required features in your jurisdiction.
Support and Parts Availability: Support from the manufacturer or supplier and the availability of spare parts is also a key consideration, particularly for older models. You want to ensure that you can source parts and get support when required.
Seller Reputation: Purchase from a reliable seller. Reputable sellers offer transparent communication, accurate machine descriptions, fair pricing, and after-sales support.
Return on Investment (ROI): Finally, always calculate the potential ROI. Consider the cost of the machine, the operational cost savings it will bring, and the potential for increased productivity. This will help ensure your purchase is a sound investment.
There are several well-known manufacturers in the field of bar feeders that have been recognized for the reliability and quality of their products. Here are some key players:
Iemca (a division of Bucci Industries): An Italian company with a long history, Iemca is one of the leading manufacturers of bar feeders worldwide. They offer a wide range of models suited for different machine types and production needs.
LNS Group: LNS has a strong global presence and is known for its innovative and high-quality bar feeders. The company offers both short and long bar feeders, along with a range of other peripherals.
FMB Machinery: FMB, based in Germany, is another respected name in the field. They manufacture a wide range of bar feeders, known for their reliability and performance.
Edge Technologies: A division of Hydromat, Edge Technologies is a US-based manufacturer known for its innovative and robust bar feeders.
Lexair/OML: Lexair (based in the USA) and its Italian counterpart, OML, are known for their well-designed, efficient bar feeding systems.
Haas Automation: Though more commonly known for their machining centers, Haas also produces reliable bar feeders as part of their extensive lineup of automation equipment.
Remember, while these are renowned manufacturers, the best choice of bar feeder will depend on its compatibility with your current machinery, your operational needs, and your budget. It's also vital to consider the condition and maintenance history of the equipment if you're purchasing used machinery.
Bar feeders, as the name suggests, are used to automate the process of feeding bars or rods into a CNC lathe or other types of machining centers, saving significant labor time and improving efficiency. Here's a simple overview of how a bar feeder works:
Loading: Bars are loaded into a magazine, which is essentially a storage area in the bar feeder. This can often hold multiple bars at once. Loading can be done manually or with a lift-up mechanism, depending on the design of the bar feeder.
Feeding: The bar feeder pushes a bar from the magazine into the lathe. This action is usually performed by a pusher or feed tube, which moves the bar forward.
Machining: Once the bar is in the lathe, the machining process can start. The lathe will then cut, shape, or form the bar according to the programmed operation.
Bar Change: When the first bar is almost fully machined, the bar feeder prepares the next bar from the magazine for loading. As the remnants of the first bar are ejected from the lathe, the bar feeder immediately pushes in the next bar, minimizing idle time between bars.
Repeat: The process repeats, with the bar feeder continuously supplying new bars for machining as long as bars are available in the magazine.
As a general guideline, you might expect to pay anywhere from 10 000 to 40 000€ for a new bar feeder.
Entry-level models from less well-known manufacturers might be available at lower prices, often starting around 10 000 EUR. On the other hand, high-end models from established brands, equipped with advanced features like automatic loading systems and adaptable bar size capacities, could go up to 40 000 EUR or more.
For used bar feeders, you will need to count between 6000 and 10 000€.
It's also important to consider additional costs like shipping, installation, training, and any necessary accessories, which can add to the total investment.
A bar feeder's operation helps maintain continuous production without the need for manual intervention, significantly boosting the efficiency of machining operations. It's also worth noting that different models of bar feeders might operate slightly differently, and capabilities can vary, such as maximum bar length and diameter they can accommodate.
