Print Page Bar Feeds or Bar Pullers?...
What's the difference between a bar puller and a bar feed? Well it's fairly straight forward, a bar feed is interfaced to a turning centre and feeds bar into the headstock of the lathe and through the chuck into the working environment. Working in conjunction with the CNC control, the whole process is automated, this allows an operator to focus his efforts elsewhere.
A bar puller is positioned on the turret or toolpost of a lathe, working off of an M code the turret is moved into the chuck area, the chuck releases the bar and an M code activates the bar puller, gripping the diameter of the bar. The turret (Z axis) is then retracted pulling the bar into the working area. This concept is popular and often used when less volume parts are required and limited floorspace to accomodate a bar feed is an issue.
The drawbacks of a bar puller include using shorter bar lengths which will increase material costs due to greater remnant. Also you will lose a working station on the turret and you can only machine one bar at a time. On the flip side, it's far cheaper to buy a bar puller and far easier to set.
A new barfeed will cost approximately £8,000.00 as opposed to a bar puller costing nearer £500.00.
