    Hi Raayaa 1962:
    Can't you just phone him?
    I assume this is an older manual machine where you can't just look up the tech on the control from a previous program.

    If so, you'll never get there...

    Hi All:
    There is another approach that has not received a lot of press which may actually be a better use of our collective resources and that is to find an effective way to support those...

    Hi again Vancbiker:
    Yep you're right on; my machine is a 5C gang chucker that you cannot even turn the coolant pump on or off without a command, and yes it has a 7" monochrome display.
    It's clearly...

    Hi Vancbiker:
    You wrote "You need to blame your cheapo machine builder for that, not Fanuc."

    Consider it done...blame has been apportioned, a satisfying rant has been ranted and a load is off my...

    Hi All:
    So far as I know (and certainly on my Oi TC lathe), the keyboard has no way to put in parentheses, and it treats all characters within parentheses as a single block, so if you try to edit a...

    Hi Booze Daily: Cobalt Chrome has no iron in it,...

    Hi Booze Daily:
    Cobalt Chrome has no iron in it, so it's quite different in chemistry from 17-4 PH.
    However it is about the same hardness as 17-4 in condition H900 (maybe a bit harder).

    Good morning sfriedberg:
    That is an illusion.
    I made a bunch of Vee blocks ages ago when I had a big block of hardened A-2 left over from an abandoned project.
    I took the chunk and just wire cut...

    And here's the last of the parts; simple turning and wire EDM.

    And here's the last set:

    So I made two turned parts, then cut them up on the wire.
    Next I made a sleeve to hold the halves together and tacked them with the laser welder after aligning the split...

    Hi again All:
    So today I made a housing for these little grabber parts and I thought I'd walk everyone who is interested through the process, just to get all our minds off that damned coronavirus...

    Hi TeachMePlease:
    There are a couple of factors that make the situation in our town what it is.

    First, I have no idea how many shops the customer actually contacted but I do know there are not...
  13. Another small project biopsy simulator grabber

    Hi All:
    Here's another project I was given to make recently.
    It is part of a prototype grabber mechanism for a surgical simulator.
    Milled on a Minimill with a 6K spindle and then cut off on the...

    Hi Thunderjet:
    That's a very cool way to do it...I've never even thought of trying it that way...probably because I'm spoiled by having a wire EDM so I've gotten mentally lazy.

    Besides, since I...

    Hi turbotadd: It depends a bit on how accurate...

    Hi turbotadd:
    It depends a bit on how accurate you need them to be.
    The very best way is to cut them on the wire EDM.
    The process involves building a jig to hold them but you can cut hundreds at a...

    Hi thenrz:
    Are you still going to go with C145 (tellurium copper)?
    Were you aware you can get flat bar from McMaster Carr?

    If you do it in Telco it will be so damn easy you'll wonder why you...

    Yeah, the operative word here is "approximates"
    Of course, if your microscope is discriminating enough that is true of all processes that make gears, but there is a fundamental...

    Hi Nibleswick:
    Did you remember to tell the machine where the tip of the tool is supposed to be?
    Don't forget, the place where Z0 is depends on where the tool tip is and it changes from tool to...

    Hi empwoer:
    I have had success using a 3 flute endmill that has been necked back until there is only about 0.100" of the flutes left.
    Even better, if you remove the side relief and let it cut only...

    Hi Milland:
    I think we actually agree on most of it.:D
    I fully concur that a D bit is a non starter for production.
    I also agree that drilling for roughing the shape is the fastest, safest way...

    Hi again Mud:
    OK, I think we have beaten the subject of whether to CNC turn these or not to death, and all your points make sense to me.
    So the next best option is to come up with a form tool by...

    Hi Mud:
    A quick comment on materials:
    If you have a choice I'd pick 303 stainless or Leadloy over mild steel especially if you plan to form turn these with a zero rake tool.
    Mild steel will tear...
