Hardinge CHNC4 Retrofit

[lavrgs]

The coolant system is one area I haven't addressed yet. I see the pump and coolant tank. I will try to determine if there is old coolant that needs to be purged. After that I will review the wiring diagram that I just received to see what I can do to start the pump. Would it be as simple as activating the contactor?

I was able to activate the coolant pump - didn't run it long because there is too much stuff stored inside the enclosure...9-)
I was going to check the coolant first, but that's next...EDIT There is coolant in the 30 gallon tank but the pump might suck air. I don't know what in there, would be best to purge and start over.

I am not sure how to bench test an intact machine... I don't want to remove servos limit switches etc. What do I need to consider for start up? Might as well think about while I have some time before the AlLin1DC arrives.

I bought a 16C collet to see if I could fit it into the spindle - success! The 16C-5C adapter that came with the tooling had problems that didn't let me thread it onto the drawbar.

If you are missing the compact flash card (hard drive) containing the operating system and software, then any kind of startup test is not going to be an option.

If you just want to see/hear the axes move, you could disconnect the servo motor power leads from the SERVO1 drive and hold them to a car battery (or battery charger) to apply 12V to the motors. Take care that you do not run an axis into its end stops, since of course limit switches are out of the picture during this kind of test.

You can replace the missing computer power supply with any ATX or SFX (micro-ATX) supply.

I can provide a compact flash card with Linux and CNC10 v2.72, plus report files from a similar machine, for $320.

I have already ordered a new control. I will be offering some items for sale. It is my understanding that the servo1 board will need to be returned
I hooked up a power supply to the old computer and it's DEAD 9-). There is a card in it I will remove - I think it pairs up with/communicated to the PLCIO2
Spindle motor and axis drives and coolant pump has been tested. That was required prior to ordering the new control.

Typically, it is only the CPU10 board from inside the computer that needs to be returned, in order to receive a discount on the software licenses for the new control kit.

Ordered a manual from Ozark

Today I will take a look at encoder cables...I assume that the multi pin connector for the Servo1 would also be required for the Allin1DC. Because all the cables were cut I will see if I have enough length on the Motor side to reposition the control cabinet on the rear of the machine. In the worst case I could splice them together but I will also investigate running new cables. What is the recommended cable ; do servo and spindle use the same type?

If you'll pardon the web store links, we sell the same cable we use in our pre-wired assemblies and connector kits so you can build them to length. Servo and spindle encoders will be fine using the same cable type as long as the conductors physically fit the components.
