I am trying to get into a used VMC here. I have found a used Cinci 500 local to me that is in pretty good shape. It does have a bad Z axis drive unit in it and the fellow that is selling the machine has bought a beautiful new VMC that is much larger and more powerful so he just wants to sell this machine rather than try to fix it. The machine is under power and can be turned on to check it out. He says it will go right up until the Z axis tries to initialize and then it alarms out. He removed the Z drive and showed me where there are some brown spots on the terminals. I have found out that you can have these drives repaired for around a grand or so from the manufacturer. It has the Control techniques control on it. He has been very forthcoming with any issues the machine has and he has given me the option to repair it where it stands under power in his shop before I buy it as long as I pay for any parts and we would make a contract about this. He seems like a very honest fellow and has some nice equipment in there. He said this machine was his first CNC vmc and he used it for several years to get his business going. He also said he had the Y drive unit repaired about a year or two ago. Right now it is just sitting in his shop and he wants the space.
He has offered it to me for a very low price since it is needing repair and I was just wondering what you guys think about this. Does anyone here have this same machine with the same control? How do you find it? He did say it is 3d capable altho it does not like to run very fast while doing it. I am pretty much gonna pick it up unless you guys tell me it is a problematic or bad machine. It certainly LOOKS to be in good shape and from the looks of the rest of his machines he does not appear to be someone who abuses machinery.
I am also curious as to what you guys are using to power these machines and how much air consumption I can expect with this machine. I have a capable vertical compressor but it is not unlimited. I think it outputs like 13.5scfm at 90 or something like that. Will this be adequate? Anyways, Any and all help or advice would be appreciated. Peace
