What is bar feeder?
A bar feeder or barfeed is an optional piece of support equipment that allows barstock to be automatically loaded into a CNC lathe, greatly increasing productivity. The feeder is attached to the headstock with a lathe adapter and filled with bars that are then moved through into the work area.
What is the bar feeding automation?
Bar feeding automation works for manufacturers making turned parts in volume. Most CNC lathes, screw machines and Swiss-style turning machines can accept a bar feeder. Applications include hydraulic components, couplings, specialty washers, nuts, bolts and screws — as well as watch and machine parts.
How does a bar puller work?
Rather than pushing a bar through a lathe’s spindle and into the workzone as a bar feeder does, a bar puller, installed in a turret station, pulls the bar out of the spindle. The lathe’s turret positions the puller to grip the bar and then retracts along the Z-axis, bringing a portion of the bar into the workzone.
What is bar capacity in CNC lathe?
about 23 bars
Bar diameter directly affects the capacity of the bar feeder. Typical of most bar feed manufacturers, the majority of the 12-foot magazine bar feeders offered by CNC Indexing will hold about 23 bars at 3/8-inch diameter.
What is the main purpose of bar feeder and bar puller?
What is a bar puller? Like a bar feeder, a bar puller also allows a CNC lathe or turning center to run on its own, freeing up operators to focus on other jobs. Rather than pushing bars through the lathe’s spindle, a bar puller pulls the bar from the spindle, grips the bar and then moves it into the work zone.
What is a bar puller used for?
A bar puller is a tool for automatically drawing in material (round tubes or solid bars) on a CNC lathe. The machined part is cut off and new material has to be fed into the machine.
What is a bar lathe?
Function. Bar pullers are used in CNC lathes to automatically draw in bars from the clamping chuck. In this case they serve as a substitute for a bar feeder on an NC/CNC lathe. The clamping chuck is fitted directly into the turret of the lathe or into the bar holder.
How many axis are in turning?
Although they might look alike, horizontal CNC turning centers are an evolutionary leap from the CNC lathe machines of the past. Lathes, by definition, are 2-axis machines. Once lathes evolved to include 3-axis, 4-axis and 5-axis capabilities, they became known as turning centers.
What is meant by canned cycle?
A canned cycle is a combination of machine movements that perform machining operation like drilling, milling, boring and tapping. This cycle simplifies the program by using a single block with a G-code to specify the machining operations usually specified in several blocks. This cycle is also called as fixed cycle.
Why do you need a bar feed system?
Bar feed systems help improve productivity, throughput and quality, but in order to achieve the most benefit from them it is essential that a bar feed system be matched to the particular needs of the turning operation. Bar changeover for this single bar feeder is about 3 minutes.
How does a bar feeder and pusher work?
Both styles have their advantages, whether cost, accuracy or speed. During operation, a pusher retracts all the way to the end of the feeder, a new bar drops in to the channel, and the pusher feeds the bar in as it is needed. The channel keeps the bar from vibrating or moving up and down.
How big does a bar feeder have to be?
Spindle-length loaders only load bars as long as the lathe spindle. Clearly, the floor space they take up is a lot less, but the customer must cut the bars into 2-, 3- or 4-foot sections to the length of the lathe spindle. Another advantage of the 12-foot bar feeder is that it produces fewer (and typically shorter) remnants.
