You might consider a manually acutated table.
There are two styles, push-to-index and rotate-to-index.
We use these style tables allot on two pallet verticals, mounted on top of horizontal pallets for 5 axis postioning, and verticals where positioning only is needed.
On the push-to-index type tables, the table has a plunger on the top of it, you simply take the tool in the spindle push down on the plunger, at 200 ipm or less, and it unlocks the rotary and indexes a pre-set amount or you can push it multiple times for larger index amounts. Accuracy is 15 to 30 arc seconds on this type with up to 2.5 tons of clamp force, it uses shot pin type clamping, very reliable and lasts just about forever with no backlash, about $5,700.00 for a 210mm/8" table.
On the rotate-to-index type tables, the table requires a actuator kept in the magazine, you tool change the actuator into the spindle then plug it into the table and rotate, this style uses a curvic coupling so indexing accuracy is great around 5 arc seconds and no backlash ever
and clamp force over 3 tons this style is more expensive around $12,500.00 for a 10" table.
