We are in the market for a new piece of equipment. We currently cut mild steel sheet and plate with a CNC plasma table. We are looking at the feasibility of upgrading to a laser. The typical...
Are you getting any kind of error code on the Hypertherm when the torch misfires?
1/8" would be more than enough for support the load. I think you could even get by with something as thin as 16 GA. This is also going to be dependent on where the dryer is positioned on the angle...
I would agree that this sounds like an electrical noise issue. I had something similar after changing out the motherboard on my computer. The x and y directions would stutter and lose position. In...
Hi Bradley, It's an ASRock B75M-GL R2.0. If this one isn't compatible with your computer I'm sure ASRock makes one that is.
Sorry Bradley,
I forgot all about it. I will make a note to check on this tomorrow.
That is the correct brand but I'm not sure which model I have. It is going to be slightly different for your computer because you are running Windows XP. I'm at home right now and my plasma table...
The replacement motherboard that WinCNC sent me is made by ASRock. I don't recall the exact model. I am using Windows 7 on this particular computer. WinCNC indicated that ASRock motherboards are...
I had a similar problem several years ago after the motherboard on my computer was replaced. As long as the torch was off the pattern was correct. As soon as I fired up the torch the table would...
I have had issues with the 45 amp fine cut consumables as well. In my case it is almost like the arc gets weak and it can intermittently struggle to cut all the way through the steel. It's not all...
I had something similar happen several years ago after I had to change the mother board on my computer. It would have an intermittent stutter in either the X or Y direction which would lead to out...
Thanks for the info. I didn't know if you were doing some type of special cleaning that I didn't know about. I typically change the swirl ring after so much use. It doesn't prevent the stuck...
Hi Flyinwilly,
You mention that you still have a few "stuck consumables" and that doing a complete cleaning of the torch could resolve this. What type of cleaning are you doing? I too have stuck...
The picture of your consumables is indicating that you have moisture or oil contamination issues. My consumables use to look identical to this and I tried quite a few different types of filters...
100% agree. I said it wrong and didn't catch it until I hit submit. What I meant to say is that in an FEA analysis it will show that the higher grade of aluminum can handle a higher load because of...
I would have to agree with Triumph406 on this one. The engineering formulas are tried and true. The deflection formula only takes cross section and Young's Modulus into consideration. Knowing that...
I think you are over complicating it. Unless you are going to see some major swings in the ambient temperature where your machine is kept I don't think you need to worry about this. The machine...
There are a couple mistakes you are making in your calculations. If we just consider the cross section to be an 80mm square section the moment of inertia would be 3,413,333 mm^4. This is a...
In general FEA is a tool (computer software) that helps to determine stresses for different shapes/geometries. It is particularly nice on complex shapes. It will quickly tell you where the high...
If you are good at math and physics and have a mechanical mind it really isn't difficult. It is a tremendous amount of work though.
I think one of the more important aspects if you are going to...
I wanted to add to my comment above to better support what I was saying. The only time you could consider using the full surface area of the hemisphere is if both bodies can be considered ridged and...
I would agree with kawazuki. The surface area bearing the load is going to be much less than the surface area of a hemisphere. The majority of the load will be carried near the bottom of the...
We manufacture 1000's of parts using plasma cutting and we have run into the same question about deburring. For just pure deburring we use either a tumbling process (part on part contact) or a wire...
I would highly recommend the Shop Sabre brand. I can't say enough good things about them. We purchased our table back in 2010 and we use ours for production cutting. It is a very well built unit...
I've experienced the exact same issues on 16GA as well. Just as Jim Colt mentioned it is only when the consumables are new. I too found that raising the cutting height up a bit drastically reduces...
Can you feel any vibration in your gantry? Also check to see if your torch is moving or vibrating too.
As it was mentioned many times already, mactec54 you are confusing HP with torque. The HP can't change. One of my engineering professors use to always say that "there are no free lunches". You...
I would highly recommend the Hypertherm brand. I have owned both the Thermal Dynamics A80 and Hypertherm Powermax 85. Absolutely no comparison between the two. I also do a lot of cutting on 1/4"...
I'll second the Shopsabre brand. We bought the 4896 model (4x8) back in 2010. I looked at many different brands and really didn't like what I was seeing until I came across the Shopsabre. It is a...
