We also thought it was some sort of shipping bracket at first but it definitely is not.
Imgur: The magic of the Internet Picture of drawing attached. It is the pivot point to the arm that releases the pullstud during tool change. It has some sort of shims but we cannot tell because this is the only drawing we have of this machine. We have reached out to essentially every dealer/service dept. we can for any information related to this. We are waiting for response but until then the machine is down.
I was trying to find the internals for Robodrill / Curtis Wright original concept … And (temporarily) gave up.
The thing that caught my eye is what appears to be a mini river / trail of dissolved goethite corrosion products that appear to make trail out of that Tapered washer, bushing , / (whatever it is) cap screw part.
[looks like something that should be lubricated is not and has failed somehow ? i.e. a seal may have failed also. ].
On some machines the inside of the castings are not finished / sprayed with a sealer just left to actively corrode very slowly. Red goethite indicates active (higher rate) corrosion whereas black magnetite ferrous corrosion products indicates slower corrosion processes that also have a surface passivating effect.
From the picture (it's only picture can't really tell) they may have used a bronze type of bushing for the pivot bearing, (depending on which bronze) they used and the composition of the spindle tool changer lifting arm there could be active corrosion in how that assembly seats. [Galvanic corrosion where key components are left "Anodic" to the rest of the machine... In simple terms something could be behaving as a sacrificial anode (like on a boat).].
@Yasnak is there a maintenance manual to show you where particular points have to be lubricated / inclusion of grease nipples etc. Or maybe they used an oil impregnated sleeve type bearing where they thought lubrication might not be necessary?
Maybe reach out to Robodrill or Brother Speedio service people for any procedures to fix that or tackle that... ?
I.e. how to pull the machine apart, have it serviced; the machine is only a few years old right ?

Daniel Jend of Jend Machinery in Colorado was aiming to sell Bulova but I see also they are not on his "Books" anymore. He sells good machines like OKK too.
I went through some of their literature (at the time) … They bill themselves as "Micro machines" but there really wasn't anything I could find that would make them any more precise or accurate than a Robodrill.
I think around the IMTS before … (Not 2018/2016 ) 2outof3 was kinda pouring scorn on these machines and kinda predicted that these guys would go "Belly up/Tits up"/Tank... He is usually given to smothering things in the nest before they can gain traction (which in business is not a bad way to go if you are in very competitive sectors and slim margins) , but to his credit he may have "Called it".
