    Looks a like a pressure switch, or possibly sensor.
    What's stamped on the side of it?
    And is there a small adjusting screw between the terminals? It may of been sealed over with some sealer/paint (if it has a screw, then it's most likely a switch)
    .
    Probably some form of monitoring that tells the controller that lube is actually being pumped. Where does the wiring go to?
    Do you know if it's a one shot type pump (fires single shot every xx minutes), or a continual pressure pump (pumps/maintains pressure constantly)?

    The wiring goes nowhere. It ends with a wire with 2 ends and labelled 'lube pump'. Thing is - pump runs with a relay activated. I dont know what this does. I might try and open it to see.

    The manual talks about only running the lube pump once the slides have moved 16meters. Since this is now a Mach 3 system, there will be no such logic.

    Does anyone know what parting tool actually fits into this turret? Most are too long and cannot turn behind the turret when it does a tool change.

    It's definitely a sensor of some kind, as it just connected via bog standard T-piece.
    It could be the pump is designed to only run for a set period, after a set pressure has been reached, then switch off. If it's a continual pressure pump, then I suspect it's not meant to run continuously on such a small machine.

    I'd guess just a pretty standard insert parting tool would work (small tip type, not big flat blade type), with the holder cut shorter if needed.

    Thanks. The problem is to tighten into the slot you need to get behind the tool. Ive done some CAD drawings of the setup. Just rendering them quick, not sure if it will show the issue.

    I made a bracket but out of alu which bent. Might try one from steel instead. The issue is the Glanze tool I have has a max of 25mm, so not ideal. The blade type would be better.

    Ive drawn the blade holder in glass to see through it. It can be shortened, as it will hit the rear of the turret (centre).

    The issue is how to tighten the 'spacers' that are use to squeeze the 12mm tight against the turret (vertically)?

    The question is how to get to the nuts to tighten up.

    I could drill the holes at 30 degree and use the drill bit holder 'holes'. A bit risky and need a sine vice for that. Alternately perhaps cut slots to allow me to get to the size 8 spanner to tighten up.

    What diameter would you like to part?
