Re: Unimat 12 x 1 mm 4 Jaw Chuck Numbered Jaws.

Did you get the chuck new?? One explanation I can imagine is that the jaws were not original to that particular chuck and were made for a chuck with a ring type adjustment that drove all four jaws at once.

Hello the Forum.? Looking at a Unimat DB / SL 4 jaw check, the jaws and jaw positions ARE numbered 1 thru 4.

Somehow I doubt these were fitted to each chuck. With 3 jaw chucks, the individual chuck jaws are different, to

match the scroll chuck. You do want to put the jaws back in the correct place and in sequence engage them.

This is not true for the 4 jaw chuck. These jaws are the same ! The screw adjusters are the same. (they though

these are NOT numbered. WHY ARE THE JAWS AND POSITIONS NUMBERED ?

?

THANKS FOR ANY RESPONSES.
