Maybe a product like this for coloring oils:

My new to me Okuma MC-4VA has been siting for about 3 years.
I want to make sure the entire oiling system is working properly.
I have removed all the way covers for access.
The lines I...
New(er) encoder did the trick. Machine started up and ran well! Very exciting!
Thanks for the reply. I ordered another encoder to swap.
I also determined the -SB suffix is servo with brake. Shouldafigured that one out!
Hi. My Z axis motor got hit hard enough to fracture the motor end cover. Although the encoder looks OK, I am getting an error "065 ALARM P" "SVP start 1021A08"
It also says Memory Test OK, Load SYS...
I ended up buying an American Rotary DIY panel which has the better electronic voltage control built in. I hooked it up to my used 40hp delta motor, and it started right up. Hooked up to 125A single...
I ended up with a 1989 or 1990 machine. Date on Z axis motor was 11/89, would this be a 1990 model?
I just finished installing a 40HP RPC, which does start up OK on a 125A breaker.
Still getting...
After poring over the schematics, it looks like the 3rd leg is the one to use.
L1 and L2 are used for the single phase loads.
Quite a bit of stuff is 3 phase, including the spindle control, axis...
I need to change my new to me machine to 220 3ph from 480V.
It looks like power comes into the main on/off switch, then goes to a multi tap transformer assembly next to the ATC.
I think I just need...
FWIW, phase converter vector drives seem to be available to 20hp

Hi. I just hD a moment of sheer insanity and bought an Okuma MC-4VA mill for my home shop. 10hp spindle.
Machine manual lists power requirements of 26kVA which works out to about 65A at 230 3ph,...
In the back of my mind, I am thinking to replace the control system with something more modern. I think my big question is can I use the existing servo's and encoders? I need a new vector drive for...
Hi. I am looking to buy a much more capable machine than the X4 I have now. My son is a CNC technician, and he recommended an Okuma MC4VA or similar. He really likes the box ways which he says are...
I could interpolate the slots. The bore dimensions for the counterbores are pretty important.
I need to create two slots in a part. One is not straight, it has a jog in it. The endmill is the same size as the slot.
I can't figure out which toolpath to use, and how to handle the entry and...
I have an Enco lathe that is giving me a weird wavy pattern when I face a piece of bronze bushing stock.
I have tried different spindle speeds, feed speeds and cutters.
It almost seems like the...
Nice build! Plenty of food for thought. Do you use a homing switch, or just zero it manually?
Thank you,

Hi. I have a Syil X4 and want to convert a Shars 6" "Yuasa" style rotary table to be an A axis.
My machine was missing the 4th driver, but I purchased one from Syil. The control board and Mach3...
Hi. I bought a used Syil X4 which came with a PC running windows 8.
It has one parallel port and a serial port, plust USB.
The machine came with a CandCNC hand controller, and some kind of a...
Hi. looking for a relatively inexpensive 4th axis rotary table, like the type used by Syil, Tormach and other small to mid-size machines.
For use with CNC 4th axis.
I have a budget of $200 to $300...
Hi. I have disassembled the table to my RF-20 to clean everything before adjusting the feed nuts and gibbs.
I'd like to remove as much slop as possible from the thrust washer assembly.
Is there a...
