What size Aloris Quick Change Tool Post do I need for my lathe?
The required tool post size is a function of the swing of the lathe, and the center height dimension. The center height is the distance from the top of the compound to the centerline of the spindle. There is a chart in the middle of the Aloris catalog with tool post recommendations for most common makes and models. If you have any questions call us and we will recommend the proper tool post for your lathe.
How does the Aloris Tool Post mount on my lathe?
On most makes and models of lathes the Tool post is attached to the compound by the t-nut that fits in the t-slot of the compound, and is tightened down by the flange nut on the top of the post. For those machines without a t-slot in the compound alternative mounting methods are available.
What size t-nut comes with the tool post?
As every lathe has a different t-slot configuration t he tool post is supplied with a blank t-nut whose size is dependent on the series tool post purchased. The t-nut is manufactured from non-hardened steel, and is easily machined to fit the slot on your lathe. If you supply us the t-slot dimensions for your lathe, (filing out the chart on page 3 of the catalog), at time of purchase we will machine your t-nut at no charge.
I use 1”, (or ¾”, 1-1/4” etc.) tooling. What size Aloris Tool Post do I need?
This would generally be referring to the size of square shank tooling being used. The size of the tool post would be determined by the slot size of the #1 turning & facing holder as specified by the “B” dimension on page 4 and 5 of the catalog. The tool post still must meet the center height requirements.
Why is center height important?
To properly cut material on a lathe the tool must be at the centerline of the work piece. If the tool post is too big for the machine the tool will not be able to get down far enough to reach the centerline of the work piece. If the tool post is too small the tools will not be able to reach high enough to get to the centerline.
How do I adjust my tools to get to centerline?
Each holder has a height adjustment assembly for setting the tool to centerline. This is mounted in the center of the holder and is comprised of a threaded stud, a knurled nut, a hex nut and a keyed washer. The knurled nut is adjusted till the tool is on centerline, and then locked into place with the hex nut.
What part #'s do I use for ordering?
Use the part#’s just as they appear in the catalog. For a CXA Tool Post use part# CXA. For a #1 holder for an AXA Tool Post use part# AXA-1. The same is true for spare parts. The part# to order a 1-R chipbreaker is 1-R. Will my CXA holders fit on a CA Tool Post?
Will my CXA holders fit on a CA Post?
No, the holders and the tool post must be of the same series. This is due to a difference in the dimensions of the dovetail. As the size off the tool post and holders increases the size of the dovetail increases as well.
Is Aloris Quick Change Tooling interchangeable with other brands?
Yes, with the exception of KDK, which uses an entirely different system, other brands of quick change tooling are interchangeable providing they are of the same series. Aloris was the originator of the Quick Change Tool Post system and set the standard for tool post and dovetail sizes. As the other brands were imitations of the Aloris system they duplicated the sizes and fits found on Aloris tooling. Of course, as we do not manufacture their products we cannot guarantee they will work, or speak for the quality of their products.
