  1. Electromagnet Chuck Rebuild - Proper Potting Compound to Use?

    I'm in the process of rebuilding a Walker 8x18 that had a coil go bad due to liquid intrusion. I have the chuck stripped apart and did the math to order the correct length of magnet wire to make new...
  2. Re: Surface Grinder Spindle Rebuild Recommendations, Ballpark Costs

    I appreciate the guidance. I gave some thought to regrinding the taper using the CNC itself with an NSK Planet 550 air spindle fixtured horizontally to the table to do the regrind. Either way, I'll...
  3. Re: Surface Grinder Spindle Rebuild Recommendations, Ballpark Costs

    Agreed that I may find other contributing issues. I balanced, mounted, dressed, unmounted, rebalance, and re-dressed. I was able to get workable results when I made sure that I maintained the...
  4. Re: Surface Grinder Spindle Rebuild Recommendations, Ballpark Costs

    Thanks for the feedback. I turned here after dressing and balancing and having a tough getting a decent finish. It became apparent when I saw the runout in the taper. I am balancing with near zero...
  5. Surface Grinder Spindle Rebuild Recommendations, Ballpark Costs

    Hi Folks,

    I recently picked up a Chevalier Smart B818-II as surplus. Its definitely in need of some love and a new enclosure. The machine itself is mechanically (ways and ballscrews) and...
  6. Re: Fanuc 16i SRAM Parity Error - Faulty SRAM Module? Sanity Check

    No love clearing from the IPL menu either. Bad module it is. Now for the argument with the vendor over the return and replacement. :-/
  7. Re: Fanuc 16i SRAM Parity Error - Faulty SRAM Module? Sanity Check

    memoryman. Thanks for the additional tip on IPL. I was testing by trying to restore the 3MB backup from another machine when the RESET+DELETE failed, I should have clarified that. Also, the test...
  8. Fanuc 16i SRAM Parity Error - Faulty SRAM Module? Sanity Check

    Hi Folks,

    I have a 16i-MA (A20B-8100-0130 Main board, A20B-3300-0050 CPU, B0F4-19) that I am trying to upgrade from 1MB SRAM to 3MB SRAM (A20B-3900-0020). I'm getting an SRAM parity error when I...
  9. Re: 16i-MA 4th Axis Behaves as an Index???

    Just to tie off on this, it turned out thare was an option parameter that was turned on which should not have been. Apparently, when the 4th axis was removed a while back, the person that did it...
  10. Re: 16i-MA 4th Axis Behaves as an Index???

    @freakycnc What guide covers that parameter? I can't find it in any of the 16i or Alpha manuals. I just want to make sure I understand what I would be poking at.

    Edit: The indexing options...
  11. Re: 16i-MA 4th Axis Behaves as an Index???

    @oetkbyentc Mostly from memory. Bumped 9900 from 3 axis to 4 to get it to register the extra amp, bumped up the cnc controlled number of axes from 3 to 4 in parameter 1010, then completed the FSSB...
  12. Re: 16i-MA 4th Axis Behaves as an Index???

    Mostly from memory. Bumped 9900 from 3 axis to 4 to get it to register the extra amp, bumped up the cnc controlled number of axes from 3 to 4 in parameter 1010, then completed the FSSB and servo...
  13. Re: 16i-MA 4th Axis Behaves as an Index???

    Pretty sure its not a missing option, as the machine was originally purchased (by previous owner) with a 4th axis that supposedly was capable of synchronized motion. The old 4th axis ended up being...
  14. 16i-MA 4th Axis Behaves as an Index???

    Hi folks,

    Does anyone here happen to know what needs to be changed to have a 16i control assign a 4th axis as a fully controlled axis instead of just doing indexing. I have a 4th axis that I've...
  15. Fanuc 16i-MA Controls (2) for Sale, Reasonable Offer

    I have two Fanuc 16i-MA controls available for sale. Both are the exact same build and in the same condition, so I'm only posting photos of one. Both of these controls are factory optioned for RISC...

    Macro Compiler For 16i

    I'm in a position where I want to add some in-house custom screens to machines I already own. They have a few custom p-code macros on them already that are stored in F-ROM, so I know the macro...
  17. Miyano TSV-35 - Need Toolchange Macros, 9000 - 9003

    Hi Folks,

    Our shop had someone we trusted with machine maintenance turn out to be a bad actor that (I can only imagine intentionally) deleted the macro-a toolchange macros from an older TSV-35...
  18. Re: Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    I *THINK* this is the correct pickup, but really would want to confirm before buying one.

  19. Re: Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    @bumzag Correct. The alpha spindle motor manual has the channel signals designated as PA/RA, PB/RB for this, but its purely semantics. Each channel is a differential, twisted pair, which is what...
  20. Re: Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    @zavateandu. You are correct regarding the gear ring that is currently installed. So, just to confirm, the external magnetic sensor wouldn't be sufficient to provide the single pulse per revolution...
  21. Re: Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    No worries, let me elaborate further and hopefully it will make the situation clear.

    What I currently have for the new 16i based control setup is spindle motor a3/8000, model A06B-0853-B100...
  22. Re: Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    It's able to do that with just the standard pulse generator (a/b 1v peak to peak sine) and an external 1 ppr index signal? I thought a motor with a bz or mz built-in coder was needed. Basically, a...
  23. Fanuc Alpha 3 Spindle Motor - Add Position Coder?

    I'm putting together a retrofit to upgrade a tapping / light duty machining center from an old 0MC to a very well optioned 16i that I picked up (was previously in a high speed machine, so it has all...
  24. Re: Docs For Fanuc Operator Panel Boards (A20B-2002-0520, for example)

    Got an immediate sidebar comment with an answer, so I'll post here in order to have the info out there for anyone wondering or searching with the great google. I kept thinking if this as I/O, but...
  25. Docs For Fanuc Operator Panel Boards (A20B-2002-0520, for example)

    I'm planning out the upgrade of an older Kitamura from its original 0C to a (new to me) 16i-M. I already have all of the hardware (control, amps, servos, IO module, etc.) and have worked through the...
  26. Did you ever figure out the cause of this? I...

    Did you ever figure out the cause of this? I have a Kitamura MyCenter Zero that exhibits the exact same behavior and it drives me nuts. You have to do a zero return after reset in order to get back...

    Re: Fanuc 0T-B PMC-L backup

    If you are backing up the ROMs, you only need a generic EPROM reader/writer. The TL866II is a pretty common universal reader/writer that a lot of folks have used successfully. It’s the one I have...
