    My F4 and F5 are both OEM battleship gray. Like most everything else on those machines, the finish is up to Swiss standards. It is not far from bathtub enamel. I think the castings may have been...

    There is no spindle lock interlock on my F4. The F4's spindle lock is practically useless IMHO. It slips too easily. I just throw the machine in low gear and work against the spindle motor inertia...

    All I’ve seen on Woods’ epay account are an over arm and dividing head. I have an over arm already and a Hardinge DH. I’d be interested in a right-angle universal head and a 6-T-slot fixed table. The...

    I am bummed that I could not find the word Aciera in the catalog. I was secretly hoping you found a stash that belonged with the sweet F4 I bought from you a decade ago.

    Replacing the wires with intact wires fixed the problem. The original wire seems to have stiffened and possible shrunk away from its retaining clips. The replacement wire is more tightly gripped by...

    Here are the broken wires.

    The cable is routed under a clip on the side of the carrier below the red block, down to the floor of the...
  7. Aciera F5 Spindle Lock Electrical Interlock Repair

    My Aciera F5 was originally equipped with an interlock switch that was supposed to prevent turning on the spindle motor when the lock was engaged. That feature was broken when I got the machine. I...

    Speaking of which, I finally got around to fixing the drawbar reed switch (mine is more like a normal switch) interlock on my F5 after a near disaster in which I left the spindle lock engaged and...

    Here you go. This is the horizontal drawbar from a late 70's Aciera F4.

    Look at that, the former mayor of Philadelphia, PA, reincarnated. He probably was missing the publicity.

    Explain. The losses in both a Kingsbury (which is hydrodynamic) and cylindrical hydrodynamic bearings are due to viscosity in a thin oil film undergoing shear. The viscosity can't be very different,...

    Can you conjure a way to mount the motor on your mill's table and fix a lathe tool somewhere stationary? Feed the motor along the tool or vice versa using the handwheels. My guess is that you will...

    Huh? No more so than any fluid film bearing. They would not be used on big gas and steam turbine generators, hydro-turbines, and so on, if losses were significantly greater than other kinds of...

    If you have a corner-grounded derived delta system on the secondary side of a transformer, make sure there is no fuse or untied CB in the grounded leg. Otherwise, if you get a fault between one of...

    You probably want a 63C or 71C metric frame motor. WEG has this one that is about 5.5 inches OD. It's 3/4 HP, which should be plenty for that machine. Multimounting High Efficiency 0.75 HP 2P 71 3Ph...

    Can you change to carbide tooling and run without coolant? It'll be way less stinky and you can run 3X as fast at least.

    TNB,
    Thanks for the detailed reply. PM is fantastic! As to the Swiss over-complication, Schaublin's lobed triangular solution to the "problem" of keyed or splined shaft connections is Exhibit A. At...

    There are several YouTube videos about Schaublin 13 disassembly, but I could not find one that showed the rapid feed motor. Did not all 13s have rapid traverse?

    I did it to my Dad's 9" SBA when I was a kid. I'd have to really lean into it with the lathes I have now, so much so that there'd be no point.

    I need to pull mine and clean the clutches because the feed clutch slips after a rapid up move. I’ve been in there before. I used to have pics on PM, but might be gone.
