Your recollection and mine are different. I remember coming in grinding one spindle and returning the next day. I was asked to check the first machine again. Upon inspection I noticed significant...

I need to clear something up on this thread. I have worked for Spindle Grinding Service Inc for the past 22+ years. I have handled the calls that come in from the Wichita area. I have NEVER told...

Right. Only talking power drawbars here. Most really don't know how much force should be there. This week I fixed a taper and checked the drawbar on a Mazak 50 taper. It showed 600lbs. The customer...

Since we repair spindle tapers, we check drawbar force on every machine possible. I've seen machines that had a force of zero on the gage and they still are running, complaining of finish problems....

Could be a couple of things. I would first check tool knockout. I know they want the gap set to about .100", but that is just an estimate. Hold a tool in the taper with the draw bar unclamped. Then...

You also need to take into consideration the condition of the spindle taper. ALL spindle tapers wear over time. They become bell mouthed. The big end gets bigger. When this happens creates less...

I was a skeptic of the Fair Tax until I read the book. To me it makes the most sense of any alternative we have. EVERYONE pays the same. Rich, poor, middle class and the underground economy....

No one is going to like strick enforcement, but come on.....300 miles across Iowa last week and 1 state trooper on the road. That's all I saw. And Iowa doesn't have that much interstate. I80 is the...

How about this for an idea? 60mph national speed limit. Minimum fine of $500 for speeding. The state can keep $250 to use as they wish. Maybe hire more police to enforce the limit. The remaining...

Ya know? THere is a real simple way for the US to stop using so much gas. SLOW DOWN!!!!!! I have to drive every day to get to my customers. Maybe as much as 1500 miles a week. Just got back from 2...

Actually non-drying high spot or prussian blue works best. It does'nt dry so you can use less and get a better feel for any bell-mouthing.

Part of the problems we see in the regrinding of tapers deals with coolant. Coolant gets on the tapers, transfers to the pots, dries and gets sticky. Chips stick to the tools and transfer to the pots...

Bottom line is you are worth what the market will pay you. You might thinks you are worth $30 and hour, but if the market where you are is paying $15, then tha'ts what you are worth. I'm trying to...

You said a mouth full. Not that I'm complaining about my pay...but I also work for the best people I have ever met. That's one of the advantages of working for a small company. You get treated like a...

Hey! Wait just a minute! I would never consider myself to be as smart as Walt himself. He is what we call the "guru" of spindles. I'm just one of his lowly employees. But seriously folks....we just...

Gar:

Logical explanation? I couldn't tell you. I've never concerned myself with the frequency of the vibrations that we fix. It just seems that since the problem has been going on for almost a...

I just found this thread. I didn't see if the fit of the taper was ever addressed. If not, try using a good holder and some high spot bluing. Not the liquid or spray dykem. Use prussian blue. A thin...

Sure there are oil fields in Alaska that could help with the problem. But sooner or later oil will be gone. I have driven all over this country doing my job, and it is a beautiful place. I understand...

Ford is making trucks and cars that run on E85. I saw E85 in Hutchinson, MN last week for $2.20/gal. Not "cheap", but less that gas. So we have the technology to make the vehicles. We have the...

You've got it. a lot of trial and error by the boss and we can now do it quicker and for the most part cheaper than pulling the spindle. It's not the cost of the spindle as much as the cost of the...

I understand that you may be in a situation where nobody in yur area can regrind this thing for you. That video makes it look easy. But from years of experience, I can tell you that it is not. The...

Cutting a piece of round steel with a lathe tool won't tell you much. If it is a bad bearing, you might see some runout on the piece. You will see more runout on the side of the piece opposite of the...

There is so much that can go wrong here. Even us so called "experts" don't work on these in the machine anymore. And the tapers we do work on, we would never do by programming the machine. Again way...

A couple of things for you to consider before trying to grind the taper. Machine alignments. If your spindle is not parallel and perpendicular to the axis you are grinding with you will absolutely...

Got to be careful with that "cure" too. Any lengthening of the retention knob with a washer decreases the amount of drawbar pressure you have. That can cause a tool to come out at a very bad time....

That's about right for a 50. 4000 to 5000 isn't unusual. Some these days are up to 8 or 9000. They vary greatly by manufacturer. Some of the older 40 taper Haas were less than 1000. LeBlond Makino...

Also be carefull. If you put in too many springs, there is a chance that when the drawbar unclamps, it could compress them too far and break a few.

Too late. The new engine is in place. At least I get a 36,000 mile warranty. Maybe instead of anti seize, I should try loctite and just not ever change them. Really though, I'll just pay it off this...

Sure except the dealer repair warranty is 90 dyas or 4000 miles. It's been only 45 days, but about 6000 miles. They are going to claim that the warranty has expired which it has. I have a sister in...
