R8 Collet seld releasing?

The section about R8 states: "they are self releasing and tool changes can be automated."

I own a bridgeport serties 1 millibng machine with R8 Collets and I have to hammer the drawbar to release the collet. Thats common and I've seen it may time. If the collet or other tool does "self release" - its considered unaccurate/broken.

I'd like to change that section but wanted to ask first if there is some unknown context.

Mechanical Pencils

A very similar mechanism is used to hold the lead in mechanical pencils. — Preceding unsigned comment added by 70.230.159.92 (talk) 07:48, 15 September 2012 (UTC)

dead length collets

The problem of movement of the workpiece when a collet is tightened up is not mentioned here. Strangely it is mentioned in the article on 'chucks - engineering'. Of course, if you search for 'chuck' you wont get anything on engineering chucks.

Internal combustion engines

There is good, helpful information there about removing and refitting valve stem collets but to fit in with normal Wikipedia standards, should it not be in a section somewhere about car maintenance, rather than here? With a link, of course.

The description of the split collet and groove in the valve stem most certainly does belong here, and it might be expanded to say more clearly (a picture might be useful) how the valve spring force acting on the cap with its tapered bore keeps the collet halves held tightly together. In some older engines, which might be subject to valve bounce, and collet unloading, the wide end of the split collets has an external groove and a spring clip provides some small force to keep them together if the spring becomes momentarily unloaded, to remove the possibility of them being ejected. So we may want to improve/expand that. What do you all think? Tiger99 (talk) 19:57, 18 October 2018 (UTC)

Contradiction about ER collet collapsibility

In the section or ER collets, there's this statement:

Thus a given collet holds any diameter ranging from its nominal size to its 1mm-smaller collapsed size, and a full set of ER collets in nominal 1mm steps fits any possible cylindrical diameter within the capacity of the series.

which contradicts this statement:

ER collets collapse to hold parts up to 1mm smaller than the nominal collet internal size in most of the series (up to 2mm smaller in ER-50, and 0.5mm in smaller sizes)

Perhaps the former statement should be rewritten as "Thus a given collet holds any diameter ranging from its nominal size to its 0.5 to 2mm smaller collapsed size, and a full set of ER collets in nominal 1mm steps (or 0.5mm steps for smaller size ER collets) fits any possible cylindrical diameter within the capacity of the series."--Maximumcoolbeans (talk) 15:23, 22 February 2020 (UTC)
