Hi everyone! Long time lurker, first time poster. I recently purchased a 2007 Haas OM-2A with approx 4500 hours on it, and I'm in the process of cleaning it up, checking it out, and getting it up and running. This is my first "real" CNC mill, although it's probably considered a small toy to some of you. :-)
There are a few things about this machine that are a bit unique, and I'm hoping my post might catch an experienced eye or two:
The machine was originally spec'd with a grease autolube system using a battery-powered ********* Motion Guard Champion pump. When I got the machine, the batteries in the pump were dead. After taking a look at the lube lines in the machine, I noticed that the lines were mostly filled with oil and then closer to the pump the contents switched back to grease. It looks like the previous owner was probably using oil lube (there is visible oil on the ballscrews) and switched back to the original grease system to prepare the machine for sale. Any concerns I should be aware of when switching back to grease? I'm worried that it won't properly stick to the oiled surfaces and just fall off.
Spindle - this has the standard 30k Haas spindle. I haven't spun it up yet because I want to make sure I understand how it is lubricated first. I don't see any oil/grease lines going to the spindle assembly, so I'm assuming it is permanently grease-packed. Anyone familiar with this year/model of machine can verify?
Control - I have the Coldfire 1 control which apparently Haas no longer supports. I've read some scary posts about the expense of repairing these controls or replacing them with NGC controls. Any updates on this topic for 2021? Is it still horrendously expensive to repair or replace the Coldfire 1 control?
Thanks for your time!
