Anyone put this together? if so and any comments?

Hey Al, I built a turrtet for my Syil C6 Lathe, it is the same Concept as Rons.But Scaled down to fit the C6. The Turret Head is 5.00 O.D. X 1.25 Thick. Total Weight 19.25Lbs. Here are some pics to give you some ideas. If you decide to do a build maybe I can help you. I built the Head first as it has alot of detail. C/L of tools ect. I used .500 tools. Bob

Thanks, this is for a 9x30 Lathemaster, I have access to Hydraulic Cylinder material for the cylinder itself, how did you manufacture and attach the semi-circular base?

[Journey_Man]

The Base measures 4.312 X 3.0 X 1.5 I Stood the base up in my vise Indicated every thing square vertically. The Diameter of the Cylinder is 4.5 so it would be 2.25 rad. and used a .500 x3.0 LOC Carbide end mill (relieved to 3.25) it only goes down 3.125 deep. Then used a Boring bar to finish. (left .010) The Cylinder Bore is 3.500 X 2.75 deep. The thing ended up being absolutely flat within .001 and was good enough for my eyes.

I have been thinking of building something like this for my manual lathe.

-Journey Man - Awesome Craftsmanship!

Does it work as well as you expected?
How did you program the tool change into Mach3 (?) ?
Can you share the code to do the tool change here?

[Journey_Man]

Yes! The Turret works Excellent if a person is going to run a Gazillion parts...I built the Turret with my C6Lathe & SX3 Mill. I had to put an extra Driver in the Syil Control Box along with a 12v relay in order to make the 12v solonoid cycle. It uses M7 & M9 to cycle,which is (i think) to turn coolant on&off. I would then use the Mach turn wizards to do turn;drill;bore;thread;part off; whatever...then paste them together to make a part.Between each OP I would Put the Tool Change Macro in Like this:
Rem TOOL 1 OD Turn
Code "G0"
Code "Z3.0"
Code "M7"
Code "G4 P.25"
Code "A0.00"
Code "T0101"
Code "G4 P.25"
Code "M9"
Code "g0"
The g0 rapids the turret back 3.0 in
m7 opens;
g4 p.25 pauses the turret
a0.00 rotates to tool1;
g4 pauses m9 closes;
g0 goes to the pgm code and does the work.
I have 8 different sets of these that I use.
The rotation would be A.o tool1 A.125tool2 ect.

Journey_Man,
Do you mean add 1 more stepper driver? If I use servo driver on all axis, can I use stepper driver for the turret or I should use servo on turret. Can mach3 be used for stepper and servo.

How did you machine the 4.5 radius od the base? so you have a .5" cyl. wall to secure to, ?
The tubing I have is 3.5" I.D. Hydraulic cyl. matl. so I have to come up with a way to mount the cyl. to the base, not so easy with a relatively thinner wall?
Al.

[Journey_Man]

The Radius in the base is 2.250. You need to be able to do the base like I did it in order to mount it to the Crosslide. Also there is an O ring groove & a Counter Bore and a 1" Bore in the front part of the cyl as well as a .060 O ring groove in the face of the rear of the Cyl. I will take mine apart and post pics of the Cyl./Piston too. I am going to make another Cyl. out of 6061 to cut down the weight. Also The CenterLine of the Tooling is Based on the base it needs to be within .001 on every tool location. After I post the other pics this afternoon, you will have a better working knowledge of it.

I have been looking for an 8 posn Hirth coupling but have had no luck so far, distributors don't return emails?
Probably very pricey?

Made one of these for my SX3....Just Saw The Pic and here it is

Al.

I did a bunch of searching on Hirth couplings and just about every source stressed how expensive they are. I needed a lead on something that could give me 40 or more indexes on a diameter less than 1.5". Eventually I sat down, calculated all the coordinates and wrote a program to cut my own. That was an exercise in tedium but it works.

Hey guys - found this file out on the internet years ago - might be useful.
I see no copyright or author on it.. not sure where I got it.

[CNC-Joe]

Hey - also found the plan set from Dieter Friend's website, but can't upload the ZIP file - even though its barely 4 Megs...

Anyone have an idea of why the upload would fail?

[Journey_Man]

Hey Joe...That Is the file I used to make My Turret!...except I scaled it to fit my C6! I am glad that you found that. Look at these Pictures and then those and you can see the resemblance...I just Scaled to fit my Lathe After taking the Cyl Off yesterday,I have decided to make another out of 6061 and Anodize it Red too. Ordered This@McMaster Carr 1 each 1610T45 Multipurpose Aluminum (Alloy 6061) 5" Diameter, 6" Long. 64.88.

You don't need an 8 position coupling. Something with 16,24,32,40 etc. positions would be almost as good. The stepper would just skip a few teeth on the coupling before locking in.

With 8 teeth on a 4" dia??
Anyway, I may not use a stepper.

Sorry Al, I failed to explain my point in a logical fashion.

8 positions is 45 degree indexing. If you have double the grooves, it takes 2 grooves per 45 degree index (22.5 each), triple the grooves, it takes 3 grooves per 45 degree index (15 each).

My point was that you could use a hirth coupling with any multiple of the desired number of teeth and you could still "lock it in" at the desired 45 degree index position.

If your rotation was actuated by a stepper motor, the stepper position would be more than accurate enough to make sure the proper teeth meshed when the coupling locked up. Even if you used a pneumatic rotary actuator and some type of ratcheting mechanism I'd think you could easily get within 5 degrees of your desired position, thereby making the use of a coupling with 16,24,32,40 or more grooves quite workable in the absence of an 8 groove variety.

No doubt 8 may be better/easier but it isn't the only option.

Maybe not, looking again at the original 8 pin design, Misumi have some nice precision locator pins.
I much prefer servo if I can use one.
