Logan Single and 2-Speed w/ Brake Pick-off Drives for Your Screw Machine

  • Logan brake stops pick-off
    spindle rotation just prior to
    the pick-off collet opening -
    Parts now eject from a stopped
    spindle, minimizing nicks and
    marks and lost parts
  • Reduces or eliminates machine
    lock-ups caused by inconsistent
    part ejection
  • Second speed option for faster
    back finishing speed - fewer
    secondary operations
  • Retrofits with existing OEM or
    after market Air Pick-offs
Now, more than ever, screw machine users must find ways to eliminate secondary operations, and increase machine efficiency. That's why Air Pick-off attachments have been essential in successfully eliminating costly secondary finishing, back machining, recessing, drilling, chamfering and deburring operations.

One drawback to the air pick-off attachment: completed parts eject from the pick-off collet during spindle rotation at speeds well over
1,500 rpm.

This abrupt part cut-off often propels finished parts beyond the parts chute and into the tool zone and chips - creating nicks and marks on the part, and possibly jamming other machine components
such as cross slides and attachments.

New Logan Stop and Drop Feature

Now Logan makes it easy for you to eliminate inconsistent part ejection, nicks and marks, and lost parts with our new Single and 2-Speed Stop and DropTM Pick-off drives. With the standard Logan power-applied brake feature, parts eject from a dead spindle right into your parts chute. Our 2nd speed option enables more back
finishing speed and machining capabilities
up to 45% in many cases.

Logan Single and 2-Speed
Pick-off Drives for your Screw Machine


Single Speed and Brake Pick-off Drive Features:

  • Logan brake stops pick-off spindle rotation just prior to the pick-off collet opening
  • Parts now eject from a dead spindle, enabling finished parts to be ejected more reliably and accurately into your parts chute
  • Reduces or eliminates machine lock-ups caused by inconsistent part ejection
  • Rotational speed is one-to-one with spindle speed
  • Hidden savings - fewer good parts are lost in your coolant and chip reclamation system

2-Speed and Brake Pick-off Drive Features:

  • Eliminates secondary operations Equipped with a second, faster back finishing speed which is useful for back machining or drilling applications

  • Second-speed option provides up to 45% faster RPM than main spindle speeds
