I use a spreadsheet. I input the final dimensions in diameter and length into the sheet along with how much I want to remove in each cutting session by %. The sheet outputs my g code needed to run the tapers. I just cut and past it to notepad and save the files appropriately. I can plug in...

Mike Here we go again, you talking about things as if you know what you're talking about when you really don't. First of all, the + in our new line of shafts is all about the splice and has nothing to do with the LD characteristics of the shaft. All + models do have an open bore at the tip...

The only problem Rick is that he doesn't use any curves. The Lambro joints are straight tapered frustoms. It's not that complicated of a joint. I don't see it as causing any miracle changes to the hit either, but most of that is in our heads anyway. Royce

LosOsosCues According to Joe Merritt of Buff Polish and Grind, he recommends a SFPM of 3770 for our types of finish. He's been a pioneer in the buffing and polishing industry for a long long time. Here's a chart from his website...

Randy Well, I don't know. I would expect the ball screws were done the same way he normally does them. The tough part is that going into it, you just expect that they would be done the way everyone else does them, so you don't even ask. You don't find out it's done differently until you get...

Paul You are absolutely correct. I always try to give my thoughts and explain how I use the stuff. I usually mention the volume I do, but sometimes I forget. Anyway, my goal is to not tell anyone what's best for them, only give my thoughts and observations. I prefer to let them choose for...

Paul I don't disagree, and I said that they will work. But I choose something else. Yes, I've used the the best belts etc, etc. But, they do wear. I recently replaced both pulleys on my belt driven indexer because the teeth had worn and would allow some movement. Don't get me wrong, it's...

I found a good image of the threaded ball screw end machining. Here's the link. http://www.cncshop.com.au/index.php?main_page=product_info&products_id=107 Royce

Randy I'll try to explain this without pictures. In a threaded connection for ball screw mounting, the ball screw has 3 different sections at the end of the screw. The coupler attachment area is closest to the end and is a smooth cylinder machined to fit the coupler to be used. Usually...

Well, you know George, all I wanted was to hear some of the reasoning behind some of your statements. Each time you were questioned about a position you took, you're justification was from a completely different topic. It's just not possible to have a real conversation that way. I mentioned...

George, I tell you what. I really want to discuss these things with you, but we have to do them one at a time. So far, you've mentioned at least 3 or 4 different topics. Pick one. You pick one and we can discuss that one topic. No switching or changing. We can stay on topic until we have both...

George Here's something you don't seem to be aware of. Yes, on some controllers, the encoder feedback does go back to the controller, but do you know what the controller does with that information. On all of those systems, at least the ones that I'm a little familiar with like Fanuc, the motors...

George, He didn't say that, I did. And, it's actually the truth. Especially if you're talking about motors like the leadshine stepper with encoder feedback. In case you didn't know, Cleapath motors are built by Teknic. They are, and have been, a leader in servo motors and drives for...

George I'm sorry but you're wrong on pretty much all accounts. I don't mean to be contradictory, but the truth is the truth. I've seen several Harmonic Drive systems without cross roller bearings. As a matter of fact, Harmonic Drive Systems, the manufacturer of Harmonic systems in the USA...

George Well, I don't think this one is a cross roller, but I haven't taken that end apart as of yet. By the size and shape, I'd guess it's just a deep groove roller bearing. Just so you know, this unit is a Harmonic Drive. I have removed the motor, and found the input side of a Harmonic Drive...

Mac That was yours that Jake looked at. He came by the shop today. I have to admit that I'm pretty impressed with it. I did a quick simple backlash test by jogging the chuck jaws against a simple dial indicator. I zeroed the indicator and stepped forward and back checking to see when the...

Norplex, who was the only company to make the double black linen tube (tube made with black resin and black linen cloth), stopped making it quite a while back. They even dropped an order I had in place at the time, and it was pretty large. The reasoning I was given was that their supplier of...

Patrick Thanks, that explains quite a bit. I guess I don't really see them as any different than most other shots. I know when I line up a shot, I'm only looking at the object ball when I line things up, so I guess it doesn't really matter where the rails are. I guess I'm just different. Royce

I know this is going to sound funny but what exactly are back cuts? I've had this discussion with different people, and received different answers. Whatever they are, I don't think I have a problem with them. Or maybe I do and just don't know it, lol! Royce
