Need Help!- Near-Dry Machining???

[Kincade]

I need help adding a automated component to a CNC vertical mill.

I would like to hook an oil-air mister to a certain drill-ream job, tieing in the solenoid with and M7 to activate, and M9 hopefully will turn off. I have electritions to do the electrical 24vac through relay switch.

Has anyone here done this before?

Looking fosr a little guidence to point me in the right direction. Basically need the the program source M-code to communicate with the mister.

Machine is Matsuura RA-4F with 8 extra pairs of m-codes.

The hardware is Unist Uni-Max Coolubricator.

Thanks in advance for your help.

I have done similar things on a Haas which has the connector on the control cabinet to a relay on the board that just performs a circuit closure from an M code. Is this what the Matsuura has, a multi-pin connector somewhere that is wired in to a relay on the board?

If this is the case it is fairly simple:

You need a 12volt solenoid valve to turn on the air to the mister.

Then you need a 12volt source which can simply be a 12 volt DC 1 amp wall socket power supply.

Some wire, plugs, switches.

Your circuit just connects the 12 volt power source through the machine relay and the solenoid valve and you need a snubber across the realy contacts; your electrician should know what this is.

Hi Geof,

I appreciate your reply.

I believe it's a ice-cube relay 24v, each relay has a code number associated with it. I believe it will need to tie in the m-code by parameter with the relay switch, "some how".

I was just trying to confirm this with others who have done this before. Of course every machine is slightly different.

In your application were you able to fire it On and Off with an M-code?

Thanks.

[Geof]

Yes one code for ON the other for OFF. On the Haas the ONs are M51 to M59 and OFFs M61 to M69.

The operating voltage of the relay is not the important thing it is the voltage and current capacity of the contacts; most likely this will be up to 120VAC and a maximum of 3 amps or something like that.

Hi Kincade,

I have recently done what Geof is talking about on my HAAS TM-1P utilizing the M Codes to turn air on and off.

I currently have it hooked up to a double acting solenoid valve. I can use it to operate my Heinrich 5C air actuated collet fixture or to supply an air blast as needed. I have it hooked up to a bracket on my HAAS PCOOL nozzle so it can give me a programmable air nozzle that adjusts to specific heights for individual tools as they are placed in the spindle.

I am also working on hooking up another version as a friend of mine gave me a programmable timer that will allow me to give air blasts of variable amounts and also program the duration between air blasts (great for dry machining). Haven't finished that project yet but it will be easy to work. Just turn it on with an M Code and the timer will deliver the programmed air blasts until it gets an M Code to turn it off. It will work very similar to the HAAS MOM (Minimum Oil Machining) module except it will dispense air instead of oil.

My other item that I hope to work on soon is to make an air/coolant ring that will fit around the spindle housing of my HAAS TM-1P that can either supply air or coolant in a programmed fashion. It will have multiple nozzles.

Just some thoughts from a hobbyist machinist. If any of this interests you feel free to send me a PM and I will be glad to share some additional information.

I appreciate your time, I will keep you posted on how this works for me.
