L0 Taper dimensions please

Nov 07, 2003 4 Replies

Well, I bid on and won a collet closer on ebay. First time that's happened. ALWAYS, the item I bid on has been bid way over what it was worth. Now I'm a little scared. Probably bought a doorstop. Anyway, this thing mounts to a L0 taper. I'll be using an adapter plate that goes from A6 to L0. But I can't find the taper in Machinery's Handbook or Google. Found the major dia. but not the minor or angle. Anybody know? Thanks, Eric R Snow, No longer an ebay virgin.

Jeez, Eric, you're giving up all your accuracy with that adapter plate! What kind of collet closer is it? I bought a nice Jacobs spindle nose collet chuck for my lathe, and it was HARD to find it in L0 - there were tons of them for A6 spindles, though. Uses #91 collets, I think they go up to 1.25" ..

Hey Grant, I ain't gonna gve up nothin'. This collet closer is one of them E type. 1/16 to 1 1/2 capacity. Includes all the collets in a nice steel box. Two closers actually, One key type and the other a lever type with the lever on the business end of the spindle. The A spindles I have both use a locating device so the mount goes on the same every time. The L0 taper will be mounted to the A adapter and machined in place. It'll be dead nuts. Less than .0001 runout for the male taper guaranteed each time I mount it up. I want to put an air cylinder on the lever and hook it up to the cnc control. I'll make an adapter for the key actuated closer so I can use it on the mill. Cheers, Eric R Snow, E T Precision Adapter Maker

Thanks Errol. Right after I posted that message I googled differently and found the same page. Pays to try several different methods. Cheers, Eric
