The machines listed in the title are the four CNC machines we own. The shop my boss and I work at has a long and confusing story, long story short: there is a security interest against several of the machines and we are wanting to sell these machines to pay off the security interest, get out from underneath the owner of the equipment, and save the shop. The idea is to sell all the equipment we can live without and finance newer equipment that doesn't have said security interest. The shop is in pretty dire need to sell this equipment but we are not entirely sure what the equipment it worth. We tried contacting a company that buys used equipment and they didn't want anything of ours due to its age. I've read the rules and I didn't see anything that said we had to have a listed price, please let me know if we do need one.
All this equipment works but nothing is without fault. I'm going to list each machine with a bit of information about it, we don't have all the details as neither my boss nor I have been with the company as long as the machines have.
Takisawa Mac V4
This mill is either a 84 or 85. It has a cartridge with "Mac V5 1985" written on it, plugged into the controller. Our shop bought this machine brand new for $80,000. This is the machine that has the highest tolerances, smoothest operation, and is the most capable. The biggest problem with this machine is that even with the most memory upgrades, it can't hold a lot of large programs and still has the smallest amount of available memory. Another problem is that the hand wheel has some kind of problem that causes the machine to "jump" when you rotate it, we use the jog function to get around this and we know it's not the wheel itself because we have swapped it with a known good one and the problem persisted. This machine also has a reeless, high speed, paper tape reader on the side. Our programs were originally typed on a Teletype 33ASR and read into the reader on this machine.
As of writing this the operating hours are: 17030H 01M and the cutting time is: 11598H 15M. I get the feeling those are not completely accurate but the machine is still in excellent condition.
This machine has cut steel, tool steel, stainless, cast iron, brass, plastic, and aluminum since I started working here in 2018.
As a side note, this is the machine we are the most sad to see go. It's in great condition and has very few problems. And, as a second side note, this machine has made parts for the Howard Hughes Aircraft Company as we used to be an R&D facility for Hughes.
Takisawa TC-2 Lathe
This lathe is from 87. This machine has a problem with holding its X home position. As long as you don't turn off the power, it won't have a problem. We aren't entirely sure what the cause of this is. We home the machine when we start it, set everything up with that home position, and send it to a safe distance for doing tool changes. We just ran a test to see if it has to do with sending the machine home without power cycling and it didn't have the same problem. This means that if you are running 1,000 parts you are going to want to run all of them without turn the machine off or you will have to reset a few things.
As far as I was able to tell, this machine doesn't have any way to tell what the hours are.

Takisawa TW-20 Lathe
This Lathe is a bit nicer than the other, it has a bar feeder and a chip conveyor. It's from 95. The bar feeder has a 12 foot long and 2 inch diameter capacity. The bar feeder is a hydraulic driven unit that we use as a backer and we feed against the turret, it can not feed to a specific length like a servo unit could. The chip conveyor is not Takisawa branded and I'm not certain if the machine would be able to turn it on and off as we use the buttons on the side of the unit to control it, it does connect to the machine through a cable. The biggest problem with this machine is that it has a faulty spindle drive amplifier. This means that it can't handle super high torque. specifically, it can't handle super heavy cuts or use a tap (it also won't stop quickly, there is no braking action for the spindle so it has to spool down). I believe it can do everything else and I know it can do threading (just, not with a tap like I said).
The bar feeder is about 18 foot long.
As of writing this, the run time is 191H 42M.
This lathe has cut steel, stainless, tool steel, brass, and aluminum since I started working here.
As a side note, this machine has also made parts for the Howard Hughes company. In fact, we do still use it to bar feed a specific Hughes part made from brass.
Supermax Max3 Mill
This mill is from 94 but the Fanuc controller is from 89. This machine, compared to the Takisawa, has a much lower end controller. There are a lot of features missing that a newer machine would have. But, this is the machine that we use more often. It seems like this machine can do rigid tapping but I've never tried and I was always told it can't (I just think they were setting it up wrong or had the wrong value in the code). There is something wrong with the spindle, we generally run this machine at or under 1,000 RPM because it tends to sound pretty bad otherwise. That being said, yesterday I ran it at 2,000 RPM without it sounding like it was going to take flight into orbit. The version of this machine we have is the kind without a full enclosure. We are the second owners of this machine, it was originally bought by a company making wooden signs and our company bought it from them. This machine has a spot for a paper tape reader to go but it doesn't actually have one installed (it doesn't look like it ever did, either).
As of writing this, the run time is 555H 51M,
This mill has cut steel, tool steel, cast iron, stainless, brass, aluminum, and some copper since I started working here.
We have most, if not all, the manuals for these machines as well as the advertisement brochure for the Supermax. On top of that, while each machine has problems, the problems are all fixable with a little time, effort, money, and/or understanding of the problem. Our shop has little of each to spare as we fight to keep the company going. We are willing to help load the machines as best as we can but the buyer is going to have to be responsible for the actual transport/shipping of the equipment.
I'm going to work on getting pictures of each machine and I'll post a link to wherever I end up uploading them to, for now we needed to get this information out there as soon as possible.
Edit: Here is a link to the pictures of the machines, the main album is a bit of a mess and isn't entirely in order. The sub folders are properly sorted and labeled for each machine.
