    BMC30 spindle rebuild

    Thanks Everyone! Too many other things have gotten in the way of getting this done. For the spindle main bearing nut it just needs to be tight, there is no torque value, no determined amount of force. Just needs to be tight enough where the assembly is restrained. I have been trying to set...

    BMC30 spindle rebuild

    I did not get back to it over the weekend. I spent an hour or so cleaning parts and still have more cleaning to do. I plan on heating the bearings to set them to ensure that I can get them seated properly without having to force them, I am going to try to get the aluminum cone fabbed up for...

    BMC30 spindle rebuild

    Eric at Compact set me up! They had a spindle spacer that was close enough, and was able to provide the preload data for those bearings. Which preload is supposed to be 8-12 microns, I am still looking to find the best way to do that. One thought was turn of the nut, it is 1.5mm pitch. With...

    BMC30 spindle rebuild

    Seems like there is very little info on this vintage of machine, That makes sense if they got complete spindles from Taiwan and have no design control or technical information on them, they were not confident on what spindle it could be either. I would not mind a new Hurco, A buddy has VMX...

    BMC30 spindle rebuild

    Thanks again Richard, That is the video series that encouraged me to tackle it. I did mark where all the nuts were before disassembly and took measurements from stationary points. I wanted to find what pre-load should be in case someone else has worked on this spindle. I have only had the...

    BMC30 spindle rebuild

    Thanks Richard!! I did buy Isoflex NBU-15 for it and found the NSK tech manual for the bearings that states the fill for the bearings. Once everything has been cleaned once it will be moved into the room that is cleaner than where the machines are. All these areas of the shop are kept pretty...

    BMC30 spindle rebuild

    I am in the process of rebuilding the spindle in my 1992 blue Hurco BMC-30 Is there anyone here with experience this deep into the machine ? The upper set of lower spindle bearings has checked out on me. Its got a bunch of hours on it, it did not get crashed, and it gets babied. I found...

    Leblond dual drive spindle shaft removal

    Morning John, I figured the end bearing was going to be a #0. What I can't get some ole truck bearings at O'Reilly's for this? Leblond quoted me $1100 for the set there. But forgot to get me a price on the other two on the shaft, and availability. Do you think the intermediate support and...

    Leblond dual drive spindle shaft removal

    It appears that thanks to some oil sludge that plugged up my oil port to the spindle bearing it is now trashed. 2-3 thou of movement...... The spindle has never really been quiet on this machine, but still had good surface finish until about a week ago. I'll get pictures in a bit. I have...

    OT Lightning Protection- 2,000 sf residential new construction in rural NY

    I'm an industrial electrician. Yes properly designed lightning protection systems that are installed and maintained per the design specifications work very well. The plant I work at used to trip constantly in storms due to strikes freaking out instrumentation and electrical systems. $10m...

    California Power Outages

    Yes this is political and posturing for the results of the finger pointing from previous fires. You don't insulate the majority of overhead medium voltage line 2kv-69kv. Insulated jumpers are used on fuses, breakers, lightning arrestors, jumpers, transformer taps..... Still doesn't make up...

    Re-plate nickel handles

    That is what kills every plating/coating shop. If your ok with more of an "industrial" finish I sent some stuff to Precise hard chrome in Waco,TX. The pretty much do hydraulic cylinders, I had blasted and sanded the parts myself, and told them I just wanted them done with one layer as I was...

    Modbus controlled VFD: what are the best safety practices for when Modbus comm fails?

    My walker is not MODBUS controlled, only controlled from a local control panel at the walker gate. The E-STOP chain goes through the run command contact, there is a E-STOP at the control panel, which is also reachable from the arena. There is also another E-STOP over at the tackroom. I ended...
