pneumatic electro drilling unit

[stevie]

drilling a thin wall without control of relative position between piece and tip (maybe even by hand, but there must be) is guarantee not only of a job done wrong, but a great example of what not to do from the safety point of view.

in some companies (use), drilling a panel on column drill without blocked piece is right cause for dismissal. will there be a because, or are they also charlaters like those who are advising a different road in this thread?

then, that a tube can be drilled even with a screwdriver and its hammer is obvious, but everything can be done good or bad, it is to those who do the job to choose which professional want to be.

in technical detail an ace dampener serves nothing: one should not dissipate kinetic energy of a moving mass; It is necessary to maintain constant speed at the end of a load. the only mechanical system that guarantees this function is the hydraulic cylinder (or oleo-pneumatic, as suggested by wttm). as already discussed above, the most economical and functional system today, is however the electromechanical one.

so much to add some wood to the fire, you could object that the use of a tip to steps combined with a pneumatic system is certainly not a good choice, since it adds to every step a further leap forward of the tool that loses repeatedly resistance and is still pushed by the force of advancement without position control. the use of this tool on a curved surface is another force of its natural use.

wishing to discuss the type of tool, the one to use would instead be a "short" tip with angle of 90°, suitable to start the hole without preforum with tip from center. A guide compass is obviously indispensable at the entrance, while the one at the exit could be completely absent if the position control of the tool was electromechanical.

I conclude by saying that if wttm comes out of this discussion, who puts us back is the op and would be a sin. Instead, I avoid comments on certain obvious features to the eye even distracted.

I give you a shocking news...the ace damper works with the same principle of the adjustable hydraulic brake (I don't know what you mean with "hydraulic cylinder")...which then is the same principle as the pneumatic flow regulator. if you read the answers of others I have also clarified that the regulation with incomprehensible oil is much more effective than the pneumatic regulation, but that I doubt that the cost of a hydraulic brake is justified. . .
part not relevant.

I have to build a small equipment consisting of three drilling units, arranged on the same floor, at 120° one respect the other, in order to realize at the same time three holes rigged for screw m5 in an aluminum tube of a few mm thick.
I've looked at what the market offers (I don't know if you can put the names of builders) and all seem to me to be oversized for the purpose.
for an application intended to remain unique it is obvious that it is not convenient to design ex-new a drill system
I would like to know if there is a relatively compact system on the market to be considered.
the tip will be maximum diameter of 10 mm, for the race is sufficient 20/30 mm

to add other meat to the fire, always for the series "read others", the initial request previews the need to perform "wrong holes". . .
with a helical tip you certainly don't make holes fused, at least not changing it (and I don't think for reasons of productivity one wants to change tips )....
It seems that you have to resort to the tip of steps, which, by knowledge, starts from different diameters (it is not that there are only the steps that start from 4 to rise).
If I want to pierce from 8 I use a step tip that starts from 8 , it has the trait of simmer, and then the diameters to follow.

and overflight on that "cinners" that, aimed at professionals with years of experience, I really find out place.

This shows that you do not read carefully: "cilators" was addressed to me and to wttm (those who tell her different from you). I have the impression that wttm does not take it for what I wrote, even because of the reverse psychology hidden in the term. . .

if you do not read the posts carefully, then you end up writing answers... "poor adherents", like those regarding the locking of the piece. Maybe read and reformulate.

personally, with this last post, I stopped wasting time reading and responding to users who attend the forum only to give vent to their (supposed?) knowledge and to feed useless polemics that lead to nothing.
I try to cut myself out, fatigued, a little time to keep me updated and learn new things, if that little waste behind useless mouthwashers of polemics.......

 

[exxon]

Besides speaking with one who has 30 years experience in mechanical processing, I the holes on hand drill did them to 14 years...I still have all my hands!!!
that there is a slight "contraccolpo" at the exit stage I understood it as a child. . .
Today I run a company with 4 turning centers, 4 working centers, 2 5-axis centers, column drills, tangential adjustments, circulars... maybe a few jobs I understand, don't I?

Wow, almost a multinational. . .
I expected this moment, when in place of technical motivations are justified positions by adducing experience, the number of employees and "how good".
If the validity of the claims was the function of the business size that has 2,000 employees could say any cable, but... it is not so: the correctness of a statement, ultimately always depends on the usual laws of physics and mathematics, those that someone here defines "noious". . .

as well as confirmation of the chestnuts that tells.. .

... it seems obvious to me that I'm dealing with someone who maybe the drill sees him at the leroy merlin when he goes around on Sunday.. .

Careful, insults slip on me, but for a lot less, hunter wiped me whole posts. he is impartial and (as he wrote to emphasize it) does not tolerate at least that users express themselves in this way. Wait. .

I see no arrogance in the words of stevie.. .

I was wrong.

For the rest... as the unbearable Milanese says... "tiremm innanz!"

but if you have a message from a user and then my answer that was given to another message makes a false ideology, making me say what I didn't say. I understand that we are in the fake news period, but a minimum of respect for the space that is given to you....

We'll see you in a week.

 

[TECNOMODEL]

Now that, perhaps, a bit of order has been put back I try to ask a question that could give an extra point.
in a pneumatic system it would be possible to insert a system (discuss the game of words) load sensing, like the hydraulic ones to interderci?
in this way would be the resistance encountered by the tip to "definite" the necessary load and the system would follow. to decrease the resistance would decrease the speed of advancement.

I'll be arrogant though "embarrass" if you allow me not to tell by anyone, less by such who lately has as only goal to create useless polemics on a forum (substantially it is 1 month that is fighting with all users of the forum).
said this my "presuant" skills I hold them for me, I leave you to the theoretical-philosophical wanderings of some users of the forum...

please do not respond to the user @exxon that having been banned does not have the faculty to fight, thanks for the collaboration.

the system with load cell and proportional valve can only be realized if the main thrust cylinder was hydraulic. This is because it requires an incomprehensible fluid to have a stable signal of action and regulation, in order not to have instability of regulation.
therefore the only realable true system is a hydraulic damper with adjustment ring that takes for a "elastic" part the force that is generated, as if you are still drilling and the part of "smorzation" of the peak if the tip tends to start on the tube.

as I wrote in a censored message there are pneumatic proportional valves, so at the theoretical level you could reverse the signal of a load cell to vary the pressure of the cylinder.
as you have rightly said hydraulic drives have the undoubted advantage of the incomprimibility of the fluid.. .

"reading what you write is a question "but have you ever seen a drill pierce something? " This would be a "do we call for greater realism?"
I leave every other technical consideration and I stop here. congratulations to the moderator for his objective and ...moderation.

 

[meccanicamg]

I highly recommend taking in hand the Ace catalog where you see how the components workIn a very synthetic way it can be seen how braking action is constant even if the system is perturbed with a high dynamic (big variation of force in very short time).the drilling of the travases and the double room increases exponentially the internal effect of the decelerator that compensates for the non-linear effect of the physical phenomenon.
there are then tanks to increase braking capacity and brake units to be mounted before cylinders, if we want to block them in a certain position.
There are many alternatives on a pneumatic drilling board.

All very interesting, the only doubt concerns the cost.
an adjustable hydraulic brake believes costs at least one hundred euros.
the idea of a match with adjustable spring in the terminal phase of drilling that I had suggested could be good especially as cost-benefit ratio.

but you know, you usually become moderators after you have been long users, but at the time when you become moderators it is not that you stop being users. in the prerogatives of the moderator surely there is not that of technically unionizing the opinions of the users: If you take care of the moderators' interventions come only on disciplinary issues or for requests regarding pirated software, you will never see a punished user for saying that the land is flat. on the other hand it is true that moderation could be more precise, timely and attentive, but you can not always be present and sometimes something escapes: among the many professional and family commitments we reduce to moderate discussions in time clippings from the screen of a mobile phone. However, write to the administrator, at the limit will take away the "grades" ?, which I will tell you are more than a service that is done to the forum without anything in return, obtaining more the acricity of some users.
