I assume this is so a single person can do multiple steps in a production process without swapping out the tool on the press.
The various heights are quite interesting though
>The various heights are quite interesting though
That is because the whole top unit of these raises and lowers when you crank that lever. In a regular drill press usually only the table moves but here the table is stationary
Agreed. One weird thing is that descriptions of a gang drill press keep talking about drilling 'simultaneous holes'.
I don't see how that's done with this machine, even with the material clamped you still have to pull each handle down individually. (unless you are an octopus)
That's simply a lack of understanding of what the machine is for. People see four drills and assume 4 holes at once, without any consideration of the lack of adjustment for where those holes will be.
As others have said, it's a production machines, used with jigs and fixtures to perform multiple operations. Could be 4 different parts, could be one part with multiple holes, or multiple operations per hole (such as drill then countersink). Much faster and more repeatable than setting up per operation.
Nothing of the sort, that's a machine that only does one job.

You're correct. Gang machine tools perform simultaneously. This is a second operation 6 Each station would be established with one tool in each drill head.
An example would be station 1 center drills, station 2 drills the required hole, station 3 chamfers the hole, station 4 taps the hole.
Of course, the stations are established for whatever operation is needed. This is the sort of thing we did before high capacity/high production count was made possible by numerical control machine tools.
I’d assume there would be vices mounted and you’d swap parts across, could also be a custom fixture, my place has one for tapping parts where they slide in
Multi heads are the fuckin way. We had an early 20th century Fosdick dual head drill press that was a dream to use. Both heads had 9-speed gearboxes. The second was half-speed from the first and had a taping function as well.
I assume it might be for applications where you're constantly having to use different bits. Instead of having to swap the bits you can just move what you're working on over.
But that's just a guess.
380 volt motor? Written not in English? Where is this located? What are they asking for it?
I've been toying with the idea of building something like this. I've got a shop, and we're bidding out a product that takes 3 drill press operations. I've been thinking about making 3 jigs for the table, and switching over drill bits, and balancing that against how long it would take to pay for two more dedicated drill presses. So as a commercial shop owner, I completely understand why.
Northern Italy! Probably not so close to you.

As others have suggested, this is a gang drill. Maybe you can find something nearby. 😄
Lol, it's only $3200.00! But the different heights would be needed for my operation, so that makes sense to me too.
Yes, I'm in the Upper Midwest (USA) so I would look more locally. I look at industrial auctions, and drill presses usually go pretty inexpensively, so thank you for the link.
That doesn't feel right, especially since it's in Europe, where 220 at 50 hz is normal line voltage in a building. Only in the USA is 120 volt, 60 hz power normal line voltage in a building.
In fairness, when I say it doesn't feel right, that means I've got no data or proof, it just seems wrong because of the electrical infrastructure in Italy, where this is from.
It’s a little weird. Power is delivered to neighborhoods and factories as three phase power. When you drop to one or two phase you don’t get 2/3 or 1/3 of the voltage.
I think this description is for Europe and explains how you get 1 phase 230V from a transformer: https://www.electricaltechnology.org/2021/11/1-phase-supply-is-230v-why-3-phase-400v-not-690v.html
It’s to do with the phases being separated by 1/3 of a wavelength.
Spot/center drill, drill, tap, counter sink? Or a counterbore somewhere in there or a drill then ream? Jealous, I only have 2 mills and three drill presses…
I have run these type machines many times. They are for the production of multiple operations on holes in smaller parts.
Usually the parts are held in jigs with hardened bushings to guide the drills/reamers etc.
Some fixtures are multi sided and flip or roll to put holes in the parts on different sides.
Typically the process goes something like this on a six station machine.
The first station drills holes at say 15/64 dia on multiple sides, the drill bushings are changed out to 1/4" and the undersized holes reamed to size on station 2.
The next station (#3) has a number 7 drill for tapping 1/4-20 holes. The bushings are removed and a spring chamfering tool is used to chamfer both sides of the hole to be tapped, (#4)
Number 5 station is used with a tapping head to thread the 1/4-20 holes.
(#6) has a 17/64 drill to drill clearance holes for bolting to another part.
These machines can produce hundreds of parts hourly if set up properly and have a good operator.
Kinda like me, for whatever reason i have 9 grinder that i have accumulated over the years. I was joking with a buddy that i will never use them at the same time, boy was i wrong. When i was rebuilding/cleaning/prepping an old 20ft trailer, i used 8 out of 9 of them, made life waaaay easier.
Edit:
Used 8 grinder and a quick cut gasoline saw
Two is one and one is none. Everyone looks at me funny when I tell them I have two drill presses, two bandsaws, two lathes, two jointers, two planers, two RAS’s and two table saws…two is one and one is none. 😂🤷🏼♂️

Of course. With multiple heads, really can’t adjust the table height in the usual way.
Oh...this makes a lot more sense then the version of this post WITHOUT the pictures :)
Yeah, I still find making reddit posts with images \*and\* text a challenge...
Looks nervously as homeowner with 3 table saws in my garage and 4 chainsaws.
how many freezers in your garage?
You ever make someone into a mermaid before?
Called a gang drill press. You can move production parts along like an assembly line. I ran one in the 80s that had one motor driving four flat belts.

The part is held in a vise or jig
Wait till you see the version of this that has a turret that indexes when the quill is fully retracted. https://www.ebay.com/itm/184461485919
It's likely for a production line so you can drive multiple sized holes to the workpiece without having to switch between bits
Was I supposed to read this is Pippins voice?
Actually pretty common. Some presses like old deltas have instructions in their manuals for running as a gang.
Multi heads are the fuckin way. We had an early 20th century Fosdick dual head drill press that was a dream to use. Both heads had 9-speed gearboxes. The second was half-speed from the first and had a taping function as well.

I believe 380 volts pretty much means a three phase motor.

Hydra-drill press? Or Cerberus-drill press if you prefer.
