I just bought this as a project....
12 x 24 x 8" travel, highspeed water cooled spindle. I love public auctions!
I'm into the beast now, and it's not all roses. The spindle was smacked by someone (I think they tapped it with a hammer), and I don't think it can be saved. Happily, I have a 1.2 kw spindle which has identical diameter. The main board will not power up at all. I would spend more time tracing the issue, but the main board only works with the PCI cards sold by Armor CNC, and I don't want to pay $850 for a board that locks me into using their crappy 2003 software with a full form factor ATX case.The motors are servos with (really great) Renco R35i encoders, so I'm going to go with Viper servo drivers. I haven't decided which BOB I will use (any recommendations?) and I'm torn as to whether I will go with a Mach windows machine or LinuxCNC. I actually have a license for MasterCAM (from my work), but I really don't want to pay out for a computer that can run it, and I don't need all the production bells and whistles.
I ran some power to the motors to measure the backlash in the ballscrews, and I'm pretty chuffed that they all came in around 0.0004"...better than the desktop machine at work! It also came with some keen tooling that holds panels in the T slot platen. I will probably make custom wasteboards, though. That's a system that works well for me.
There is a vacuum attachment and a brush around it. I don't think the machine cut anything other than hardboard or MDF. I will put a plastic tub inside for coolant.
The servos, encoders, limit switches, ballscrews, belts, and ways are all in perfect shape, not worn at all. The enclosure is sweet, but really heavy. It's also pretty deep front to back (48") so I'll have to make a stand for it. The gantry is made of welded 14mm plate aluminum, and the base of the enclosure is 4 mm steel plate. I'm not worried about gantry flex for cutting panels. I can fit up to 120 hp x 6u into it, with a bit of room to spare. There is about 4 inches of overrun available at the front of the machine, so I may build a tool change station if it doesn't get in the way...my spindle has that capability, and I can throw it with pneumatics or a solenoid.
The door was a bitch to open after I closed it for transport. I ended up removing the latch, but I'll replace the stupid solenoid latch with a mechanical lever. Maybe I can use that solenoid for tool change.
Unfortunately, it's too wide to go through any door into my house. My shop is still getting repairs from the earthquake damage, so I may have to wait until fall before I have a place to set it up. I figure I need to spend about $1k before it's where I want it.
