RE: Emco Compact 5 CNC Lathe More Information

For a picture of the bare Lathe itself, go to:

This is the bare Lathe without steppers, and control panel. Scroll about
1/2 way down for the B & W photo of the Compact 5 lathe. Non CNC.

Scroll down to the Gray, and Orange CNC lathe photo, it is the 3 rd one
down.

This is the 3 rd Generation CNC Lathe without a built in computer, so you
can use a better, and faster computer that the "basic one" that was in the
other models, My unit is red in color.
Notice that there are few controls at the top of the control panel, I have
added 4 Led's, and 5 switches for the Reset circuit, IIRC, the led will
come on if a Gecko faults, and you use the switch to reset it. I will have to
study up a bit on what It does. in my first post, I included a link for
the control circuit .

For a picture of the Automatic Tool Changer, scroll down to the 1'st photo:

I have removed the steppers shown, as they were very weak so students could
not operate fast or jam things up and damage the lathe, To control the
changer, you will maintain a voltage for a period long enough for it to scroll
up, just past 120 degrees rotation in the up direction, then reverse it,
and drive it down on the internal Pawl, then maintain a smaller holding
voltage. If the CAM program can operate a relay for a set period of time and
then turn it off, it will be very easy to control. I can include a circuit
using one DPDT relay with the right capacity. the long motor shown on the
changer, is a motor gearbox combination, so if is easier to leave it alone
and just apply a DC voltage for a time period.

In the back of the control panel, I have a power supply on the right side
for the drive motors. There is also a regulated power supply for the other
circuit boards.
There is another panel on the rear, having the Wonder Board mounted on it,
Also there are 5 miniature relays for the Reset board. Also on the same
panel, there are four fan cooled Heatsink's, that the Gecko's mount on for
good cooling. And I have several larger relays so I can turn off various
drives. And use one to control the Tool changer.
The lathe requires an X, and a Y axis. A mill requires X,Y,Z, and in some
cases a A drive,
I planned by changing the plug-in cables on th back, to be able to power up
the lathe, or power up a small, without having a separate control panel
and drives.
My shop was very limited in space. and this was the compelling reason for
that.
Still to be done, make up the cables from the Servo's to the rear panel,
finish the reset relays, and check out all of the wiring, unfortunately there
is no complete print of the entire unit, as there are several things that
tie into each other so I just did a lot of it mentally. And it utilized
the basic circuits that abound around the internet, with various sections
added into the circuits.
The Wonderboard, is basically an opto-isolator board between the computer,
and the CNC lathe electronics.
The Reset board, is tied into the Geckos reset need.
The power supplies are pretty much universal in nature.
