dumb hbm questions

[idacal]

I never saw this mill run before i picked it up. but I have pretty much figured out what everything does. but I can't find the spindle clutch lever so stupid, I know, feel like a idiot asking this but would it have been an electric clutch originally? it does have in inch button on the ( pendant? but that momentarily starts the motor so 20 horse continuously starting) I'm sure my power company is going to love me I have to start the motor in gear and underload to start the spindle. I found and old brochure for the same model but it has an extra manual lever.
the cover for the lever is not same on mine as the brochure. the serial is 7291 so i think that's early 50s its a 340 t. I have pulled all the inspection covers off trying to figure it out its not making any sense any help would be greatly appreciated

Are you trying to engage the spindle feed? If so, If I remember correctly, on a radial arm drill, pulling those 4 feed handles together engages the feed. I hope this makes sense.

 

[idacal]

no Im talking about the spindle rotation clutch so you can change gears without shutting off the motor and then restarting under load your talking about the spindle travel feed I just purchased and downloaded a manual for it and its way different then the manual so now I need to figure out what I have.its the long lever closest to the ways

Only ever used my Kuraki which doesn't have a clutch.

I would suspect if you have a jog button you do not have a spindle clutch. It doesn't make sense to have both.

My Kuraki has a big pendant with lots of buttons. It has buttons to select fwd/rev, button for spindle start and a button for jog.

When I first hooked it up I hated it. It had a hard time starting in higher gears so I had to use jog to get it up to speed then hit start. It turned out there was a bad connection somewhere because when I moved it to it's final home and rewired everything properly it starts right up no matter what gear or load is on the spindle. A few weeks ago I used it has a lathe spinning a 4' diameter 1" steel plate and it started fine at the slowest speed, 17RPM. I dared not go faster.

Could always put it on a VFD if there isn't a clutch.

 

[idacal]

that must be what it is I just went through a bunch of google photos and the ones with pendant usually dont have the manual lever this is going to take some getting used to. I guess its safer though cant reach across a bunch of stuff and bump the lever with your knee. but if someone is scrapping one of these out I would be interested in the parts to change it. its item F on this page

I think they usually use dual winding motors in these things when they don't have a spindle clutch.

An HBM headstock has more shit going on inside than you can shake a stick at. That motor is spinning a lot of shit

You can configure a VFD with some contactors for a dual winding motor. Think spindle drive.

Though the main reason for using a VFD would be for the soft start ability.

I tried starting it up at 1000 rpm and it blew a 50 amp breaker without any facing chuck on it so Im going to have top do something. but right now I will quit worrying about it and Finnish getting it set up

Is the spindle motor on the headstock or does it use a driveshaft to power the spindle somehow?

I figured the clutch would be buried deep inside the headstock, the clutched VS pushbutton machines might be totally different animals.

 

[idacal]

no the motor is a belt drive on the back uses a vertical spline shaft to run the headstock. so far I can figure out put the head stock between gears, get the table all adjusted . then shut it off again put the head stock back in and away it goes. it will just take some getting used to. this thing is to big for my shop, cant pull a drill rig completely in anymore, if we use the line boring capability, thats what I got it for, I start looking for a smaller newer one, chalk this up as a college level learning experience lol. one option is I could put a couple of hydraulic drive motors on it and have way better control without dimming the neighborhood lights Im only aloud to start a single 25 horse motor and run up to forty horse on my power plan so I will see what jogging a 20 horse motor does to my bill. but I have a 50 horse diesel hydraulic power unit so thats one powering option. Im going to get it usable and go from there. you got to remember this is just to fix my own broken shit so Im not waiting weeks on a shop.

That's kind of the same reason I got mine. I have two big projects that need line boring- I have to rebuild the 1st reduction section of my 300 ton Bliss press and I have a very rare old 4x4 truck with a Willock chassis conversion that will need lots of boring mill work when I get to it.

I actually didn't buy mine. I intentionally DID NOT go to the auction where it was sold because I knew it would go cheap and I needed more iron like I needed a hole in my head at that time. Lucky for me one of my good friends was there and when nobody raised their hand after the auctioneer lowered the price to total giveaway I guess somehow, I vicariously raised my bidding hand through my friend Tom? I don't know, that's how he describes it (Thanks Tom). He did great and got all the tooling and associated bits for it for a killer deal. I was a little shocked when I got the news that I had bid on 25 tons of shit at an auction I never attended, but I was assured it was a good deal. When I got there at 7AM the following morning to see what I bought I realized the reason the scrappers didn't bid on it- There was a 60 foot deep vertical X-ray vault in the floor between where this machine was and the door it needed to load out of and the bridge crane was not big enough to lift this thing. Tom failed to notice this tiny detail as he was busy figuring out which lots I was buying. We got it out on the cheap and don't regret any of it. It is definitely a backwards way to end up with a boring mill in your shop.

 

[idacal]

with friends like that who needs enemies sounds like you were able disassemble it enough to get it out though and got a good machine cheap with lots of sweat labor

There was a side door to a 50' wide alley. The access to that alley was right on a major hwy. We stopped both directions of highway traffic, backed a semi and 53' trailer into that alley, used a versa lift to pick the back of the semi trailer and walk the trailer through a 16' wide door. We loaded the 21 ton HBM on the trailer then picked the trailer w/HBM with the versalift and walked it back out the door. Stopped both lanes of traffic again to get on the highway.

I try my damndest to avoid taking machines apart to move them.

...and then when you were done, you bowed to the traffic, and said "Tah Dah".....

Every horizontal borer I have ever ran is motor start/stop for the spindle. Don't think I have ever seen one with a clutch.

It should be wired for star-delta switchover for starting?

 

[Garwood]

I'd guess they went away from spindle clutches for the expense of problems caused by people that abuse them.

I have a G&L 330T. Mine doesn’t have a pedant. Your machine doesn’t have the start stop reverse lever? I am wondering if you have some wiring messed up? You should not have to start it under load.
Cheers

Those are interesting looking V-blocks.

They are interesting. The shop I purchased it from used them to face a specific part/parts.
What’s more interesting is the quick change chuck. It has 50 taper collets, 40 taper collets and 30 taper collets .
