DIY - CNC H/V Rotary Table

[QSPSB]

I am in the process of making a new DIY-CNC H/V Rotary Table... I purchased a 30 to 1 worm gear reduction unit a few years ago for another application... That failed... So I'm going to see if i can make this work... It's just a standard 30 to 1 worm gear drive reduction unit... I'm going to machine a box to mount around it.. Then mount that box in a larger one... It will be aprox.. 8'' x 8'' x 4 1/2'' I"m designing it so it can accept a table up to or there about's.. 10''/12''.. I plan on machining a 1'' x 6'' MIC-6 table for it... Hopefully it will work out for this task... My primary reason for making one is to machine 1/4 scale V8 engine cam lobs... I'll have to figure how to make an attached/removable tail stock for it once i get it built... Shouldn't be hard to figure out..

I've ordered all the aluminum and fasteners so hopefully I'll have it all and have it built in a week or soo...

Here is a few pics of the cad rendering i did on it as well as a few of the reduction unit... I did manage to machine a hole threw the output shaft casing so i can mount a 1/2'' shaft... Whew... That was fun... Nothing like trying to drill a hole in hardened steel... A 3/16'' two flue end mill even had a challenge doing so..

Well the rotary table is now done... other than squaring up the enclosure a tad that is... There isn't alot of vertical height but there is plenty of horizontal height... I primarily built this to machine 1/4 scale engine parts... such as... Cam Shafts/Crank Shafts/Cutting ring grooves/cutting gears... I still need to machine a tail stock for it and machine a grinding attachment that will mount to the z axis...

Gotta run
