Pick-Off Drives Acme Gridley

• Logan brake stops pick-off
• Spindle rotation just prior tothe 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

Typical Air Pick-off Arrangement

Ideal Parts for Generation III Air Pick-Offs Logan Single and 2-Speed Stop and DropTM Pick-Off Drives.

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.
