What can i do with these. I have 4 of the PK299 and 1 PK296. I would love to include them in my build but seeing as its my first i don't know the first thing about em. I got them from a scrap cnc at work. I also have a giant Spindle HSD ES919. that things a beast though no way to incorporate that into a home cnc.
Just Google the model numbers. For example, looks like the 299s are more or less pretty standard 4.5Nm NEMA 34s, common in XY stages. I have a couple in my mill. No idea about the 296s. Spindle's only ISO 30, so not that big, but might need a rebuild if it's got some age on it. That's probably several thousand dollars. Same price as buying a new ISO30 ATC spindle. Not sure about it otherwise.
When i say beast i mean heavy. The cnc my work scraped was in good working condition except for the problems we had with the controller. It was an old machine but only used a few times a day for custom work. Mostly single pieces we have another cnc gantry an even bigger beast with a motor twice the size. So our repair guy let the other sit until he left so they scraped the smaller one just to get it out of the way. So i tore off all the motors to salvage them.
Oh, I had a pretty good idea of what it was. I'd definitely still try and put that on a machine, it's not that excessive for the home shop, except if your power can't supply the VFD to run it. Likely need a 50A line to run a 28A motor, but I think you could limit the power level at the VFD and add some more caps to the HVDC bus to get something pretty useable out of a 30A line. It would probably be a static gantry, single column or even horizontal machine, but if it's in good working order it's too good to pass up. ISO/BT30 is probably about the limit of what's feasible to build in the home shop. The limits of what you can do as a home gamer are 1) physical space and 2) electrical power. Everything else is negotiable! That's a hell of a scrap haul though.
