Haas website says spindle nose is a2-6

A is the type of taper on the nose of the spindle. B is a different taper, not a larger spindle. Like Morse tapers versus R8.

 

The second thing is the number, A1 or A2. This is the bolt pattern on the nose of the spindle used to mount the chuck, not the bore through the spindle. One of them has an extra set of threaded holes, but I forget which one it is.

 

The last number, A1-8, for example, is some diameter measure of the bolt holes, or spindle diameter, or something. I forget exactly what diameter it is. This is the overall size of the spindle.

 

The bore diameter isn't in the specification, it can vary based on what the manufacturer wants to do.

 

A2 - 8:

• A - The taper on the nose of the spindle.
  
• 2 - The bolt hole pattern on the spindle.
  
• 8 - The diameter of some dimension on the spindle
  

 

 

Hardinge has some dimensions for this:

I would guess there are bolts going thru the face of the chuck, remove those and the chuck should come off.

 

 

Nevermind, Day late, Dollar short....
