YUASA 5C Multi Collet Chuck Block, 4 Station – 640-404

The PN# 640-404 Multi Collet Chuck Block was designed to be used either with a rotary indexer or as a stand alone collet fixture, mounted in a milling vise or similar type fixture. Four, manually operated “dead-length” 5C collet chucks are incorporated into the block. A simple 90 turn of each operating cam collapsing the collet sleeve, will activate the collet mechanism, with zero part movement when clamped.

Also available are 5C Multi-Collet Blocks in 6 and 8 station. These new models feature the same “dead length” style by use of a cam collapsing the collet sleve with a simple 90 turn, as in the 4-station block.

Now supplied as standard are three (3) mounting blocks designed to support and raise the Multi Block so that it may be bolted down to a mounting plate which can then be affixed to the machine table. The Multi-Block now includes drilled holes through the body to allow simple mounting as to a base plate.

NOTE: 6 ea. bolts are included with the new Multi-Blocks.
