Description:
Extremely versatile
Emco
Rotary Table with stepper motor positioning added. I picked this up recently with an Emco Maximat lathe.
This rotary table has been substantially modified.
Currently the rotary table has a Microkinetics 175 ounce NEMA 23 stepper motor. This could easily be changed to a more
powerful NEMA 23 motor.
The stepper motor transmission is geared 64:1 with substantial holding power as listed here.
The transmission uses 80MXL timing belts. I noticed these aren't Kevlar belts and would suggest the upgrade, as Kevlar belts are stronger.
This is an important consideration when adjusting the tension screws for both timing belts. The higher the tension on the belts
the greater the precision and rigidity (until the belts break of course!).  As it is with the existing belts, there is no free play in the table
per se but about 1/3 +/-  degree of backlash from the belts only noticeable as expected on changes of direction. I believe
this would be reduced by Kevlar belts.
A table tension system using spring washers was added to maintain rigidity using the old rotary table lock down screws.
Also a  grease port was added for heavy rotary table use. The item is currently full of grease.
Does not include hold down hardware. You will have to make or acquire these items to properly use this accessory.
Contraindications:
This is not an Emco production item so there are no instructions. If you are not  mechanically adept
you will be confounded by the nature of the rotary table setup and will never be able to get it reassembled and working properly
after a simple timing belt change. Alcoholic beverage consumption and barbituate use may also complicate the setup and use of the accessory.
Condition:
I fired it up using my CNC system and it turns smoothly in both directions. The table surface is excellent and looks reground;
there are some minor cosmetic marks on it from light use that show plainly in the photos. Overall e
xcellent operating and cosmetic condition.
There are some minor flaws in the painted plates and t
here are
some oil and oxidation stains a
s can be expected from age on the bare metal surfaces.
I didn't actually use this rotary table to produce parts but my guess would be that if you take reasonably sized cuts on each pass
you will realize outstanding results exactly as configured here. This would be a superb accessory for cutting gears or threading operations.
