Excello 604 cnc mill info.

Link P.M'd.
Here is the spindle mod.
The 'Gear' Tooth is for a tach.

Al, I assume you only did this cause something was broken??

I use mine with both the varispeed and the VFD. Set the speed in the right ballpark with the varispeed, then use the VFD attached to a pot on the control when running.

Well for one I did not like the unknown rpm with the vari-speed, also it was noisy.
I have a Acroloop motion card running Acromill with one of the analogue outputs to control it, so I can issue a M3 & S value for the spindle.
I have an input that indicates when it is in low gear.

Thanks for the replys guys,I have built a small cnc mill with stepper motors and am using Mach3 with it and I really like it so I think Im going to go with it.
So would I be better off going with the rutex drives or the gecko drives in your opinions or something else.I really like the look of the gecko drives they look really easy to wire up. But I also know they only go to 80volts and 20 amps and I need 85 volts,28 amps so I dont think they will work. Any opinions on this would be great.

Thanks Mike

If going with Mach and the same motors you could look at Larking Viper drives, I have not used them however, but it appears there are a few here that have.

The 604 was used by a few OEM's for CNC conversion, so it depends on what controller is on it?
Many had SEM DC brushed motors with old Westamp drives.
I have the original manual in PDF, this would be before conversion.

Here is a picture of my servo motor.
It looks like it says .7 amps could this be right?


Thanks Mike

What is the dimensions of the motor?
What is reduction/gearing involved?
Al.

Hi AL,
The dimensions on the motor are 4" diameter x 11" long including the tach. and about 6.5" for just the motor to the back of the brushes.
The gearing looks to be a 2 to 1 ratio.

I think the decimal is an accidental DOT!
More like 7A at least.

Hey AL,
I hate to keep asking you questions but it seems like your the only other member with an Excello 604 cnc mill. I think Im going to start another thread just on my conversion when I get a few more things done. I have started to gut the old control and Im wondering if you used your old power supply.
I was wondering if I keep everything in the main power panel or not,heres a picture of the inside of the main panel.

I think your right.

Thanks mike

Yes I used the same power supply and kept what I needed in the panel.
