Thank you for posting these series of videos. I just ordered a very similar spindle but BT30 tool holder version. Besides the low pressure air seal do these type of spindles require constant air pressure to keep the tool holder in place while it's cutting and being used? And similarly, does the 2 position 4 way 5 port switch has to have constant air pressure? I've seen different versions of the switch with some having constant pressure and others where the switch has a "neutral" position with no air pressure going trough it until the switch is pressed. I appreciate the help and thank you.
I have two of these spindles in service. Both with ISO 20 taper spindle nose. There appears to be a spring that pulls back the drawbar back, but its a good idea to keep the return side of the air cylinder pressurized so there is no chance of it riding on the end of the internal draw bar when the tool is spinning. Heat build up from friction would be pretty terrible at 8000-24000 rpm. It does not consume air to keep pressure on the return side. The air seal does consume air as does the deduster (tool cleaning blast). Extending and retracting the claw uses air only at the time it activates and deactivates but once bled/pressurized air usage is negligible.

Thank you. Most of my CamBam videos were done kind of "off the cuff" to meet a particular need I felt was easier to show in video when somebody has posted a problem or question on the CamBam forums. I didn't go out of my way to create CamBam content so much as trying to answer a fellow users question. As always if you have a particular problem the CamBam user forum is always the first best place to ask.
@@EverhardVideos If you have a particular issue ask, but I always suggest that you will get more expert help from more people by asking on Andy's forum. There has to be the best most helpful group on that forum of any forum I have ever visited on the Internet. www.cambam.co.uk/forum/
My JGL 80 ATC spindle came today. Thank you very much for that video! It is really helpful. I'll definitely build a valve setup based on your design but first I have to prepare proper spindle holder. I would like to ask you a question about air seal. How much air you have in your shop air container and how often is it launch to pump more air if air seal is on? I have small 50 litres air container and I just wonder how often will it launch to pump new air which air seal is using...
I have a 60 gallon (227 liters) compressor with a 3.7 HP motor. The pressure switch is at 125/155PSI on/off. I regulate to 125 for shop distribution. Then it goes to my air filtration. I am running three machines with air seals. I think my compressor cycles on 3-4 times per hour when all three running if I am not using air for anything else. I don't really pay it much attention. Its in a different part of my shop. It runs for atleast a few minutes each time it cycles on. Your air volume might be a little low, but your issue is not really going to be air consumption. The big deal is to provide "DRY" air. I run out of my tank to a filter separator, refrigeration type dryer, then another filter separator. Then there is another filter separator at each machine. You could use a desiccant stack, but you need to regularly pull the desiccant and dry it or it just quits doing anything. McMaster Carr sells a dual desiccant stack that dries air with one while heating the other to drive moisture out, then switches stacks. Sorry, being a damned Yankee I still use Imperial units.
You need to identify the ports on your spindle. I posted a diagram of how my spindle hooked up in one of my videos on this subject. You can use a manual valve or an electric solenoid valve, but you must have a valve with those passages and switching if installing a quick change spindle like the one I installed. I can not identify the ports on your spindle for you, but they should be labeled. Its not helpful if they are labeled in a language you do not read, but many spindle sellers have some information like that in their original sales listings. An inexpensive spindle will likely just have 2 ports for coolant. Some may have a third for an air seal which sprays air around the rotating part of the spindle nose to prevent oil, cutting coolant, and chips from getting into the spindle. An ATC spindle like the one I installed has 2 coolant ports. An air seal. An air blast port (deduster) to clean chips off the tool while its being inserted. A release tool port, and a retract tool port. Each of the air ports have a different recommended air pressure and you need to regulate pressure to each in the appropriate range. This means you will need multiple regulators. The pressures should be listed either in the original sales listing or in the documentation that came with your spindle. They may be listed in a unit of measure you are unfamilar with, but they can be easily converted to other units.

Please do more detailed CamBam videos. Your CamBam videos are by far the best ones I have found on RUclips. I thank you for them.

Just whish you were my next door neighbor, I would be hitting you up for Cambam tips weekly. Luck for you, you are not next door.:)

I am installing a new spindle and I don't understand air schemes
Can I send you a photo , for you help me with schemes

How does the control software release the tool ie automated
Not going to go full ATC at this time.
