For sale:
2x Axis feedback units from a Hardinge super precision CNC lathe. 1x Spindle feedback resolver from same. If you need parts let me know I'm trying to decide if the machine is worth more to me parted out or retrofitted, it is in very good shape, but it is a complicated machine for retrofitting. For now I'm removing & selling any parts I won't need either way. Here's the link:Where are you located? I've been sort of watching for a parts machine for my CHNC with new control. I'm only looking for iron and servos.

In Maine. I'm going to hold on to the axis servos & other critical parts at least until I decide whether to keep it or not. I only get about 10mins. a day to dig into it & I haven't even figured out how everything would need to be controlled just yet. I just discovered yesterday that the speed control servo isn't a servo after all, it is a stepper motor (I think). For a small & simple machine it sure has a lot of complicated attachments. I'd like to replace the spindle drive with a belt driven BLDC servo & If I could get enough $ in parts from the high-low clutch & brake unit, belts, pulleys, speed control ballscrew unit, motor, etc. to pay for the servo & drive ($1800), I'd sell that stuff off too.
I decided to just part it out, too expensive to retrofit considering I don't really have a use for it in my shop, I need big machines. If anyone wants to buy the whole machine as it is now before I start tearing it apart you'd better let me know soon. If you use chuckers in your shop & you're savvy about retrofitting, this machine is ready to go. It has brush type servos x & y. It needs encoders mounted on the screws, (an easy job) & a couple of digital servo drives. That's the easy part, the collet closer, tool turret, spindle speed control etc. need to be done too. It wouldn't be too bad of a job to make the ancillary stuff manually operated, the speed changer can be replaced with an adjusting screw or lever & lock, the turret is run by only 2 air valves (I have manually tested it & it works well) & the collet closer is just air operated too, the high/low speed clutches are
24vdc & could be switch operated.PolyTech Forum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
