Hi all,
I apologize in advance if this is the wrong section.
We have parts that are outsourced to China to be manufactured and we found that these parts are coming in damage. These parts are around 3W"x3L"6H" and they have very thin wall features that are getting dented. I don't know if they...
Thank you all for your thoughts. I think I will go with runout on the OD and cylindricity on the inner ID as you suggested Drawoh.
Nescius,
The engagement is over the whole entire cylinder and the thickness of the press fit tubes are twice as thick as the one shown.
Hi all,
I am somewhat of a novice in GD&T and needed some guidance on the call outs in this thin walled tube drawing. This is an aluminum tube and there will be another thin wall tube that will press fit against the OD of it. Then there will be another tube that will press against the ID of...
Andre,
Not sure if you figured it already but if you have then let us know what you did. My first guess is that your pressure is way too low to be cutting 10mm. I suggest going to at least 21 bar or 300 psi. I also suggest try bringing the focus even further down to around -8mm and -10 to see...
Hi Merrill 101,
What are your cutting conditions?
I have had success cutting Aluminum before with a Precitec head with an IPG laser on 4mm AL. Like footstrap said, it won't be completely burr free but it was pretty good and there will be striations. I can possibly show you pictures later.
I...
I have actually ordered from UKAM for a custom core drill. I was trying to cut out some tiny glass and their product was not bad. I, however, am not sure how good of a quality their wet diamond saw is.
You can refer to this thread for help as someone provided an answer for running an cost analysis on lasers.

You can also talk to your original Vendor and ask if they have any data on cost savings.
Have you tried Centricut or now known as Hypertherm? They have high rigorous quality standards and they provide nozzles to many different applications such as fiber, co2 and plasma. They also make nozzles that fits into a lot of the major laser system such as precitec, amada, laser mech...

I guess the best example I can give you is that it needs to push against a door and close it at a certain time. It just need it to do this task once just for an experiment. That's really the best example I can give you that's close to what I am doing.
@itsmoked
I looked at air...
@mcgyvr
You are right. A crank slider did cross my mind because I can just 3d print the parts but I still need it to activate on a timer. I'm not sure how difficult it would be to make a programmable though and run on some sort of motor. I believe that a linear actuator seems to be right...
Thanks for the replies.
@Mike
That's actually what I am looking for. Earlier I was searching "programming linear actuator" but it didn't produce the same results like I did with "programmable."
The only problem is that most of the programmable actuators offer are above 300$. I am, however...
Hi guys,
I am trying to make a system that drives an object in and out at a set a time automatically. The speed, power and precision does not matter. What matter is programming it to automatically move in during a set time and retract and then later repeat the process all by itself.
I...
I'm curious to see what your cut conditions are. Generally cutting such a thick mild steel will require not only high power but lower speed. Have you tried going to wider nozzle and increasing the pressure just a little? The increase pressure may help get rid of the dross by pushing the material...
Well no one really replied but I seem to figure out the problem. Apparently, people do use CW when typically cutting mild steel and I found that some OEM cheat and use nitrogen instead of oxygen. The idea is that nitrogen is inert and the high pressure will help blow the molten material through...
The fiber laser system is a YLS from IPGP and the cutting head is an old precitec head. The motion control system is an acs spiiplus. A lot of what I do is hard code the movement of the head. The system doesn't have any fancy piece options so I code the software to pierce 4mm away from the work...
