Reseat CHUCK; Centrl Mach. T-586-HOW?

[abi456]

The Quil keeps droping OUT!

[uncle pete]

Uhh, There's just not enough information to answer this correctly. The machines quill? The tooling shank? A drill chuck dropping off the jacobs taper? Yes I know you did say quill, But I'm suspecting maybe the wrong terminology may have been used. If I'm wrong, I'll apologise for that assumption.

We need a bit more information about exactly what's happening please.

Sorry, if I 'confused' the description.

Chuck...wedged onto ?Spindle -> with an end, having been shaped Flat, (on 2 sides).

This 2 part assembly gets inserted into the Drill...then, PRESUMABLY, gets twisted, (so the Flats can align with an internal slot; to drive rotation). Then 'jamed'; by action of jerkking the chuck down...driving it into a block of wood.

All this is straight-foward, except; you drill 1 hole ... and it FALLS OUT!

Is there a method for displaying CAD or 3d-files?

Clean both the male and female tapers, any debris will cause them to be unable to mate.

Insert and whack with a rubber mallet or with a regular hammer using a wooden block to protect the chuck.

Do not use the quill feed to try and jam the chuck on.

Do not whack excessively hard, You will only ruin something

Check the arbor/spindle for dings/dents.

Do be sure to retract the jaws on the drill chuck before you give it a good whack with a rubber mallet!

OK, Now were getting somewhere. I'll assume it's a standard Morse taper. That type of spindle holds due to a wedgeing action, And they will hold very tightly. BUT!!!! And it's already been mentioned, That "wedgeing" action requires both the male and female tapers to be spotless, And undamaged. Even dust a few thousands of an inch in diameter can and will reduce the holding power of a Morse taper. It's also possible that the internal taper may be damaged now due to I'd guess this problem happening multiple times.

You may have to buy a new male taper, And just maybe very lightly ream the female taper with a designated Morse taper reamer. Try seating the taper as the others have suggested. If that doesn't fix the problem? Then my points above are going to cost you some money.

Black Moon;

Thank you for the informative response.

On my first try; sloppy cleaning, of just the spindle, made a significant difference, however, ultimately, failed. I plan, to return and meticuosly clean both male/female parts.

The owner's manuel, (in mangled Chinese French), Tip; for pressing together - Drive them up, using the TABLE.

Using those, I'll give it another go!
