How to select the right fixing plate for Pullex Crocodile

Square shank part-off tool

1.When you have a shank part-off tool to be mounted on a tool holder you shall use the fixing plates with a flange together with the part-off tool in the tool holder.

2.

When you have a square shank part-off tool and there is no space for the flange, you should use the fixing plate without a flange. This is a frequent occurrence when mounting the square shank part-off tool directly on the turret.

Adjust the pulling plates to a diameter of 0,1 mm to 0,2 mm less than the bar diameter.
The pulling plates are hardened and profile-ground for best performance.

FAQ – Frequently Asked Questions 

Below you’ll find the most common asked questions about Pullex. If you have any questions about Pullex or our other products please contact us.

Question: Can I use my own part-off tool together with Pullex Crocodile?

Answer: Yes. Iscar need not to to be prepared with M6 screw holes in the holder. Other manufacturers do. 

Question: Can I use both left- and right hand tools?

Answer: Yes, the same Pullex Crocodile can be used both for left and right hand tools.

Question: How do I adjust the pulling plates?

Answer: It’s easy. You just adjust adjust the Pulling Plates 0.1 to 0.2 mm less that the bar diameter.

 

 

 

One way to adjust the pulling plates, when the Pullex Crocodile is mounted in the the machine is to use the following method:

The adjustment of pulling plates is simplified by turning a diameter of 0.1 mm to 0.2 mm less than the bar diameter. Then, the pulling plates are pushed against the turned diameter and locked in this position. This method is quick, accurate and eliminates errors originating from the turret and/or tool holder.

  • Turn a diameter of 0.1 to 0.2 mm less than the bar diameter.
  • Push the Pulling plates against the turned diameter to be locked in this position.
  • The clamping force achieved by the Pulling plates entering the bar is then amplified by the somewhat sagging bar at chuck unclamp, thus securing safe operation.

Question: Does Pullex works with a spring?

Answer: No, Pullex doesn’t use any spring which can tear out
