A bar feeder is the workshop equipment that undertakes the task of automatically feeding metal bars into CNC milling machines. Those types of tools are used to increase the productivity of a workshop and allow CNCs to work unattended and during the night or weekends.
Bar feeders can be connected to a CNC for automated control, or can be set to feed at a specific rate, depending on the application. They can hold many bars on their magazines and feed them to the CNC one by one. Modern bar feeders have the capability to detect if anything is wrong in the process and essentially stop automatically.
Consideration when selecting bar feeders
There are many different bar feeder models in the market today, offering different production qualitative and quantitative characteristics. As these machines are destined to work together with CNCs, compatibility and sizing are especially important when considering buying one. Here's a list with the most significant factors to consider before making a bar feeder choice:
Size of Magazine
The size of the magazine that holds the bars is a critical factor to consider when buying a bar feeder. Determine what type of bars you want to process (gauge class) and calculate how many of them can be held on the magazine. Then consider the feeding rate to figure out how many hours of unattended operation you can get from the feeder. Usually, a minimum of 8 hours (night shift) should be preferred.
Part and Spindle Lengths
Is the part that you want to mill long or short in relation to the maximum bar length that the feeder can hold? How many finished workpieces is a bar going to last for? What is the length of the bar that will be held at the spindle? These are the kind of questions that a buyer needs to answer before figuring out the production efficiency of a bar feeder with precision. Sometimes, a buyer will have to spend quite some time calculating all possible configurations for a bar feeder, but if a workshop produces specific workpieces at known length, the time and effort to take those into account are worth it.
Safety Mechanisms
Bar feeders are machines that are left to operate by themselves for many hours, or even days in some cases. For this reason, they should boast advanced safety features that ensure their good operation while workshop personnel is busy doing something else. Some of those features could be sensors placed in key points, load measurement equipment, and infrared beams that check the position of the bars. Modern bar feeders can even have webcams used for remote monitoring.
Floor Space
Bar feeders are installed right next to the CNC, so considering if a workshop has enough floor space for such a machine is imperative. Also, remember that it's not only about fitting a machine in a corner, but also providing for enough space for regular maintenance and access in the compartments. Finally, if a crane will be used for the feeding of the magazine, enough maneuvering space should be considered.
