So today a lot of the HAAS users got together and did some maintenance on the HAAS.
The HAAS is STILL out of Service until tomorrow afternoon sometime. We are in the middle of doing a flush.
So we cleaned the HAAS heavily.
The HAAS Kurt Vise is out of commission, the thrust bearings are toast. We are ordering the parts for it.
We removed the way covers & cleaned them up real well.
We installed the replacement tool release button.
We installed a new coolant filter.
We think we found the source of the Spindle fault, the VFD fans do not appear to come on, the fans are good as we tested them. We will likely power it with a 24 volt source.
AND MOST IMPORTANTLY a NEW Sticker. It’s worth another 30 percent better performance.
For those who were unable to participate … I saw some of the gunk that came out of the HAAS and it looked like something that would eat your skin off. Kudos to those who braved the goo and gave an entire (long) Saturday for this maintenance.
So I wasn’t suppose to come by today but did because I had some work to do. I found the old guide pin assembly for the trap door on the machine upside down. So I put the new bushing with flanged bolts on the guide for the trap door on the tool changer. I also cleaned all the tool holder tapers & ran the tool changer through about 2 dozen changes to check the operation of the trap door on the tool changer.
So I put in a power supply in the HAAS for the fans on the spindle drive. Now when the spindle is running the fans are as well. After we seal it up, I think we need some extended runs to check to see if there are any more faults.
So yesterday I re-piped the internal drain into the basin so hopefully no more automotive drain pan.
What still needs to be done is:
New wipers
New Way cover gaskets
Pulling of the sacrificial Aluminum table to inspect the table.
New light for inside the HAAS.
The last time I had the table off I cleaned underneath it. It does need to be resurfaced which will take a couple of hours. I’ll try to do that Friday.
Unless you use a tiny step-over there will be some high spots between the passes. I know - there shouldn’t be but there always is with step-overs of 40% or so. Going smaller just takes a LONG time.
Running a 2nd spring pass at 45 (or actually any angle that is not parallel to the 1st pass) will hit the high ridges and gives a smoother, flatter surface. I find this to be true on wood as well when surfacing my spoil board. cheers!
