Choosing a Bar Feeder
Bar feeders are an essential part of the equipment set of workshops that utilize automated CNC milling machines. Their main operational purpose is to feed the CNCs with metal bars used as the raw material for workpieces and resulting products. This essentially eliminates the need for manual labor on that part and allows for the continuous and unobstructed operation of the CNCs.
Bar feeders are directly attached on the one side of the CNC that features the spindle. The machine is controlled by the CNC electronic control unit that orders specific feeding rates as per the processing requirements. The bar feeder undertakes the actions of holding, guiding and moving the bars into the CNC machine.
Things to consider when buying a bar feeder
Depending on the CNC model, size, and brand, workshops can benefit the most by choosing particular bar feeder models that are perfectly compatible with the existing equipment. Technical specifications that define this interoperability are of the utmost importance in order to narrow down the choices initially. After that, buyers may pay special attention to the following four factors when choosing the right machine tool accessories:
The magazine size of the bar loader determines how many metal bars can be loaded on it. Different bar gauges will yield different results, so it is important to know how many bars you can load to the machine beforehand. This detail determines whether a particular bar feeder will service during night shifts (8 hours), or even holidays (24 hours).
Part and Spindle Length
For workshop units that are dedicated to the production of particular pieces, it is very important to first determine the exact length of the metal bar needed for each workpiece. This, combined with the length of the bar remnant inside the spindle itself, will provide an accurate approximation of how many workpieces can be produced out of a single bar. This element is very important considering the cost of the wastage and the time needed for the loading of a new bar.
Safety of Operation
Maybe the most important feature of any automatic piece of machinery is its operation self-checking capability. Modern bar feeders boast multiple sensors, load meters and infrared checkpoints that allow the remote checking of their operation. These safety measures can actively prevent potential uncontrolled wastage and damage of the equipment in the case that something goes wrong.
CNCs are already bulky and as bar feeders are attached on the one side of them floor space may become an issue. Before choosing the right bar feeder, consider the available workshop floor area and make sure that it is enough for technicians to perform maintenance work. While many things can be modified, the size of the bar feeder and the workshop cannot, so pay special attention to this factor before buying.
