Kolver: NFK Series Screw Feeders
NFK Screw Feeders | Up to M5 Screws
When it comes to speeding up assembly operations, NFK screw feeders are a game changer.
These simple and small devices are meant to avoid any time loss between one tightened screw and the next. Screw feeders present one screw at a time with no need for the operator to manually pick up each screw. Models for automated applications are also available.
Fully adjustable
NFK-N screw feeders are supplied with interchangeable spacers between the rails (spacer size: 0.05 to 0.20 in). You can also combine spacers to reach the desired rail width. Model NFK UNI can be used with any (non-countersunk) screw with diameter 0.06 – 0.20 in.
Speed up automated applications
NFK RS delivers one screw at a time to a specific position so that one single screw can be easily picked up when using an autocatcher or suction head. A trimmer on the side panel allows you to adjust how fast each screw is supplied. Available for screws with shank diameter from 0.05 in up to 0.24 in. An optional cover is available in order to avoid screws falling inside the NFK RS screw feeder.
The whole NKF Screw Feeder series can handle max. 0.8 (0.7 mm on NFK N60/RS) in long screws.
