1997 DYNA MYTE DM4800 VMC to Mach3 Conversion

[JHChoppers]

We just picked up this 1997 DM4800.  All the parts are present however the machine does not fully function.  Tool changer has issues and Y thrusts bearing was worked on before we got it.  The way covers have been removed where the work to Y Axis was performed and there is surface rust everywhere.  Not to sure DYNA MYTE machines, however it has large boxed ways, monster ball screws, 32 x 20 x 20 travel, 24 ATC and weighs in at 11,400 lbs!

Going through the electronics now to see what I can reuse and what I need to replace. 

Currently we are working on the coolant tanks and chip pans, adding new casters and Teflon sliders to ease moving them around.  Checking for leaks and repairing as needed.

woow .very interesting
I always love your changes on the machine.

WOW,

I see another long and interesting tread with lots of pictures and even some video.

Looks like a nice sold machine, never knew Dyna Myte made big machines.
Looking forward to seeing the progress.

There are 4 parts to the coolant system, 2 chip pans and 2 coolant pans.  The coolant pans sit on the floor and contain the coolant while the chip pans have casters and roll in and out from under the VMC. 

Overall the chip pans were in good shape.  The caster needed to be replaced and the dents were hammered out, then degreased, sanded and ready for paint.
 
I am starting here first so we can get the heights of all this figured out before we level out the machine IRON and the sheet metal enclosure.

Hood this thing is a beast ! 

BTW: What type of PLC do you use again for your I/O ?  I am looking for a better way to control my signal to noise ratio

Thanks,
JH

I use the DL06 PLC from Automation Direct, specifically the D0-06DR model.

Have you moved the Z all the way up yet? It doesn't look like you would have enough clearance above it for 20" of Z!

There is a guy on cnczone (caprirs) who used to work for Dyna Mechtronics and He seems to know alot about them.

I am guessing you have the Meldas 2 or 3 on this machine. I think all the DM4800's I have seen have had rigid tapping on them.

Nice machine and I know it will be even nicer once you are done with it!

I haven't moved the Z up yet, but my calculations indicate it should fit with about 4 inches to spare.  Thanks for the tip about the zone.  I think it will be very nice when its done too as the machine core is very solid.  The Meldas M3 is a good control, but I like the customization ease of Mach3 ... tool probe, 4th axis and being able to fit things when they break.  

I should be able to reuse the logic from the BP412 VMC Project for the Tool Changer, Tool Probe and User Interface to get this up and running.

Attached are specs that I used for the height calculations

Thanks

I agree about the customization ability on Mach. 

I have (3) machines with Mitsubishi controls, (2) with the MO control, and (1) with the 520AMR. If I didn't use them constantly i would love to retro the MO machines to Mach.

If the DM has mitsu brushless motors/drives on it, you may be able to re-use those.

BTW,
Have you run any serious 3d code on the BP412?
