One-Step Polishing Machine
The 6850 One-Step Polishing Machine features a dry,
single-paper technology for polishing the ferrule of a single
Hot Melt Connector. It is a 12-volt DC unit that provides
hands-free operation and delivers consistent performance.
Because no wet paper is used, no water is necessary and no
clean up is required.
3M also offers connector termination kits utilizing the
one-step polishing procedure for a variety of Hot Melt
Connectors. The 6355 and 6351 Termination Kits contain all
materials necessary to terminate Hot Melt Bayonet
Connectors (compatible with the ST* Connector). The 3M
polishing machine includes the polishing unit, 110-volt AC
to 12-volt DC converter, and 100 sheets of polishing film.
There are also adapters to polish FC and SC connectors.
