Bar puller

A bar puller is a tool to remove material ( tube or solid material, round) tightened automatically on a CNC lathe. The machined part is tapped and new material must now be tightened.

Function

Rod grippers are used in CNC turning machines to automatically follow suit rod material from the chuck. They are used in this case as a replacement for bar loader at a NC / CNC lathe.

The bar puller is installed directly into the turret of the lathe or in the boring bar. After execution, there are two different variants: Start in the X- axis ( the radius starting ) or start in the Z- axis ( direction of spindle).

Bar feeder and workpiece stop is not required when using a rod gripper.

Material

The housing can be made ​​of aluminum or steel, the jaws are made of hardened steel, hardened (steel) and burnished.

History

The history of the rod gripper begins with the introduction of NC / CNC lathes about 1980. At that time there was the conversion of rotary machines in order to produce small or medium volume low and economically.

The task of the gripper bar is tightened bar stock in the lathe without people or workers every time required to do this work on the machines. With the introduction of computer numerical control ( CNC Computerized Numerical Control) lathes, it was possible to make the individual steps (start of the turret to the material, open chuck, drawing the material, Close chuck, driving away the revolver with the rod gripper) reliably.
