    Re: My Fadal 4020 Kflop Retrofit

    HI Murray,

    Nice job with the Fadal!

    Thanks for making your C files available. I have used some great examples from your code.

    I have a question about your tool change program.

    Re: Hurco BMC20 Dynomotion Retrofit

    Glad to help!

    I couldn't figure out many other possibilities, as long shot ish as it was, it was a simple place to start.

    Angle of probe tip might be the problem, not the indicator or tip...

    Re: Hurco BMC20 Dynomotion Retrofit

    I thought it was a long shot. Would have been nice if the problem was an easy fix like that.

    Seems they never are though.

    Nice job, will be a great machine when your done.

    Re: Hurco BMC20 Dynomotion Retrofit

    Troy,

    This will sound dumb, but does your test indicator have the correct length probe on it?

    If it's not right the indicator will not read accurately.

    It will always repeat to .000...

    Re: KFlop Single Point Threading

    Works great on my lathe, and you can engage the threading with spindle off, rotate spindle by hand and the z axis will slave along so that you can line up with an already cut thread that needs to be...

    Re: Foundations for 8.5ton Bed Mill

    If the noise cannot be seen in the resulting surface finish, then it could be spindle drive settings. Plenty of splindle drives operate at high frequency and make a terrible obnoxious noise, but this...

    Re: Foundations for 8.5ton Bed Mill

    It's not electronic imbalance causing this. 20 volts is not going to cause a disturbace in the cut. Can the noise be seen in the surface finish of the cut? If it can, then the splindle bearing...

    I have been having more fun. Decided to try some aluminum parts. Machine has been performing better than I expected.

    Nice work troy!

    Looks like a good start. Going to be killer with dynomotion running things.

    I think a photo of the setup and saw could help determine potential problems.

    Sounds like a good plan Milton.

    Re: How many machines

    I must agree!

    The dynomotion stuff is great, and the service cant be beat.

    I have 2 kflop/kanalog setups.

    One setup is in a 3 axis milling machine with advanced motion servo amps....
  20. Re: Slant bed lathe, tool changer, pneumatic 5c drawbar, DYNOMOTION control, PICS!

    Hi Milton,


    Yes, mine have the 22mm nut and 19x1 thread. I was surprised by the small nut too.

    Do you think they will work in your machine?

  24. Re: Slant bed lathe, tool changer, pneumatic 5c drawbar, DYNOMOTION control, PICS!

    Thanks Milton!

    Its been a fun build, and its nice not making these parts on my manual lathe anymore. I ran into some problems along the way, but now that it is running, its working really well.
  25. Re: Slant bed lathe, tool changer, pneumatic 5c drawbar, DYNOMOTION control, PICS!

    You won't have any trouble modifying the flat, they are hardened but not super hard. I would say 48 to 50 rc no higher. Carbide cuts it just fine.

    Hope they work for you.
