how to set up a atc tool changer from china

[eloid]

Hello looking at buying a ATC Chinese

I would like to know how to wire it into the bob
how do the pneumatic controls, what are the correct Pressure Switch and solenoid valve to purchase.

You're going to have to provide documentation for the specific spindle and breakout board you're using.
Even then, you'll need to find someone familiar with the specific hardware you'll be using. I think I've only seen one or two of those here.

im using a C32 - Dual Port Multifunction CNC Board [C32]from cnc4pc as my bob

CNC4PC

Spindle is not purchased yet...tring to figure out this puzzle.. before I order it.

This is what I have been able to come up with in my search, my background is not pneumatics so I need some help



clean shop dry air in (point 4)
Compressed air filtering 5um (point 5 in diagram)
Compressed air filtering 0.1um (point 6 in diagram)
Pressure regulator (point 7 in diagram)
Pressure Switch (point 8 in diagram)
5/2 Monostable solenoid valve, including connector coil etc (point 9 in diagram)

Question? how does this get wired into my bob
What are the i/o setting in mach?
I understand someone wrote some marco for the tool changes year ago.....anyone using them?

This is the top drawing of the atc spindle



with all the ports for the spindle Im interested in.

4.5 kw atc bt30 220v

I found a video helps illustrate the 5/2 actuator assuming the spindle uses a dual action piston



I hope this helps others,

Im a little worried about what it said about the piston, "The cyclinder is double-acting: It must be kept under pressure to maintain the piston in the upper position, far from the rotating parts."

If I understood that correctly, then what happens if your compressor dies or suddenly loses air pressure in another way?

If I were you, I would implement some type of warning/shut down system for it. SOmething like a electric pressure monitoring relay/valve. If the pressure drops to one reading, it will sound an audible alarm or visual indication, if the pressure continues to drop, it will initiate a shutdown sequence for the spindle/machine. Saving your spindle in the even of a full pressure loss, allowing that piston to fall into the moving parts.

It should be pretty easy to do. There are pressure valves/relays on the market that can be purchased.

Commercial machines have a pressure switch in the E-Stop circuit, so the machine shuts down if air pressure is too low.
