Product catalog summary
Introduction
The document introduces the PULLEX® System, a revolutionary bar puller designed to enhance the efficiency of CNC lathes by integrating directly with the part-off tool shank. This system allows for rapid repositioning of the bar, significantly reducing cycle times compared to conventional short bar feeders.

Specifications
The PULLEX system is compact, allowing cut-off operations close to the chuck jaws. It feeds the bar within 1.5 to 2 seconds, compared to the 10-15 seconds required by traditional feeders. The system is designed to save approximately one day of work each week.

Design and Application
The PULLEX system forms a single unit with the part-off tool shank, eliminating the need for an extra tool-post. It includes a fixing plate that fits between the tool shank and the part-off tool, and a frame that attaches to the fixing plate. The system is adaptable to different sizes and brands of tool holders.

Operating Cycle
After cut-off, the spindle stops, and PULLEX advances slightly behind the bar center to grip the bar. The chuck jaws unclamp, and the bar is pulled into the new cutting position. This process is quick and accurate, reducing errors from the turret or tool holders.

Adjustment of Pulling Plates
The pulling plates are adjusted by turning a diameter slightly less than the bar diameter and pushing the plates against this diameter to lock them in place. The clamping force is amplified by the sagging bar during chuck unclamp, ensuring safe operation.

Spare Parts and Compatibility
The document lists spare parts for both shank and blade applications, including various fixing plates and screws. The fixing plates are versatile, suitable for both left-hand and right-hand tools, and can be mixed with different frame sizes.

Conclusion
The PULLEX® System is a highly efficient and profitable accessory for CNC lathes, offering significant time savings and operational accuracy. It is distributed by MPC Automation Systems AB, based in Stockholm, Sweden.

The PULLEX System You can’t possibly get the work done faster than by using this revolutionary Bar Puller, which forms a single unit together with the part-off tool shank: - it clamps the bar instantaneously after cut-off and spindle stop - it pulls the bar into its new position simultaneously with the tool’s retraction for automatic tool change. PULLEX’ extremely compact design allows cut-off very close to the chuck jaws. PULLEX feeds the bar within 1.5 - 2 seconds, to be compared with the job of a conventional Shortbar Feeder, which would take 10-15 seconds to execute the same operation. Then,...

Adjustment of Pulling plates This method for adjustment of the pulling plates is quick, accurate and eliminates errors originating from the turret and/or tool holders: 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. The Pulling Plates are pushed within their grooves (in the direction of the arrows) into the desired diameter within the Frame´s...
