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. There are two different versions, depending on the design: Start on the X-axis (starting ...
The progressive stamping die is placed into a reciprocating stamping press. As the press moves up, the top die moves with it, which allows the material to feed. When the press moves down, the die closes and performs the stamping operation. With each stroke of the press, a completed part is removed from the die.
CNC lathes and screw machines have accessories called "bar feeders", which hold, guide, and feed the bar as commanded by the CNC control. More advanced machines may have a "bar loader" which holds multiple bars and feeds them one at a time into the bar feeder. Bar loaders are like magazines for part blanks (or pallets for milling work) in that ...
