Denford Triac VMC with ATC Conversion / Fix

**uli12us** · 19-10-2015

Can you post some pics of the ATC parts. I have a (I think) similiar machine with Pickup ATC and know what you need for this part. IIRC aou want to buy 110V solenoids for the pneumatic harness. I would better use only 24V, you can them
connect directly to the PLC output (if the amperage of the Output is enough)

Can you post a few pics of the mill in position. Nice idea with the castors. Will do the same to mine I think . What kind of rapid feedrates are you getting on the machine?

Ill take some pics of the wheels this weekend.

Feedrates, about 2000mm/min at max before I see PID issues but I dont believe ive tuned the new motors properly. I need a laptop with a serial connector for the software and 2 attempts to use either a USB cable or PCI to Serial connector havent worked.

That said, 2000 is plenty for most operations. I need more spindle rpm / power now ideally as most of my stuff is Alu.

If you could post some pics of the mill too that would be great.

The 10000rpm spindle on the new Tormach 440 would be really nice on the Denford. I have emailed Tormach to see if it is possible to get one as I would like to fit to my Triac.

Some pics below. A bit rushed this weekend, let me know if you want pics of anything specific.

Thanks

any update on your build did you finish the atc conversion?

Hi,

Yes, its fully working with Mach3. Id like to redo some of the wiring but its working as needed. Ive since installed an AC Servo spindle as the DC motor wasnt working well.

Any details on the servo conversion?

I've currently got mine in bits, and am currently working on the finer details of how the servo is going to fit.

Ye, Ill share some stuff when I get home. I had to do a fair bit of test fitting due to the constraints of the physical space. I am using a 1.5KW Panasonic servo.

Sorry, are you looking for info or advising me?

I can post pics on the weekend, anything specific you need? There is also a drawing on the Denford main forum that shows how the bits fit together.
