Can an oil lubricated industrial air compressor be used to feed air to the ht2000 with a refrigerated air dryer and numerous filters with drains on a timer?

Or is it better recommended to by air...

I have come to a jam where i need to make a decision on how to move forward.

My hypertherm 45 is just not cutting it (no pun intended) for me. I am loyal as heck to Hypertherm and it is the...

Actually the motor is doing the moving, not so much the backlash/clearance. The motor is reacting to the load we are putting on it through the belt/pulley and chain/sprocket...

Hey,

My total reduction is approximately 9:1 on the y axis. The reduction consists of pulleys-belt and sprockets-chain.

Youtube movie here shows how much the y axis moves when I put about 20...

Is there a belt adjustment? Are you ordering a belt for this? Looks good! Erik

dan, words dont mean s___t post up pics now! ya slacker.

Its a hypertherm 1250.
My electrodes are holding up good.
My nozzles are not!
Im using a hand torch for now (it came with the machine) but with unshielded nozzles.

I have a water bed and the...

My consumable life is quite short. I get about maybe 60 pierces and less than 1 sheet of cutting (4x8' , 1/4" mild steel) before requiring a consumable change. From reading other posts, it appears...

I know these consumables are designed for thinner materials but...

What parameters are you using?

Go to any university or technical institute that has a mechanical engineering program.

Get a book on Machine Design.

But please note if you will understand the content in the book better if you...

I just got one of these sliders off ebay for cheap (see link) and i say cheap because they saved me a crapload of time to build them and they come with a motor (i changed mine to a servo from a...

I wouldnt worry about it.

I used a single motor in mine

My gantry is probably 200 lbs i cannot remember.
Im turning 1 1" diameter solid shafts that...

F = force
m = mass
a = acceleration
T = torque
w = rotational acceleration
I = inertia
r = radius of shaft

F = ma
T = wI

You could put the a bit you want to use on your router and put it on the router on the wood you want to cut and then turn it on. Push the router at the speed you want it to cut. How much force does...

Robin im glad i met you on this board here. Hopefully we can check eachothers calculations. Do you go as far as calculating the inertia ratio of the servos? Apparently from a robotics point of view...

lamicron let us know what you come up with. Your motor should have no problems turning that heavy beast of a gantry.

Post your calculations with explanations and we can check them for you....

I wouldnt bother lowering the weight until you do the math.

My gantry is big and heavy (see www.ubcustom.com/cnc) and on top of this im turning two 6foot long 1" shafts. I barely have any friction...

Does HF stand for high frequency. I know with TIG welding you have something called a high frequency start, and if you use that you can start welding without tapping the electrode onto the metal. The...

Ready to re-start another revolution to standardize SI units Robin? lol

Erik

You can go with belt drives too.

A = ( change in velocity / time )

So calculate your maximum velocity you want the machine to accelerate to. For instance lets say 12 in/sec. Your initial...

My table is similiar to yours.

3 I beams spanning longidutinally. 4 hss holding each I beam up giving a total of 12 legs. Each leg has adjustable feet with swivelling capabilities by use of...

Hey man, give me a shout at [email protected] and give me your number etc and we can hook up? I will be off work and in Edmonton Aug 17 for 4 days. I live close to 97st and 137 ave, about 5 kms north...

Where in canada are you?

My buddy and I rebuilt an old CNC table installing new equipment.

We also build a pretty bad-*** cnc table that is 90% finished (buddy went off to build a house and I...

Why have the water so deep? My table's waterbath is only 1 inches deep at the most. I have not used it yet though.

240lb gantry, 1000ipms, 1 450ozin (approx) servo. Horizontal gantry though. If it was vertical, my gawd i need something probably 10 times larger at 240lbs!! (shudders)

Its all about the...

hope this helps?
They are pretty beefy and quite a steal for the amount of alumium you are getting and its already machined!

Erik

check out mine at http://www.ubcustom.com/cnc/index.php?img=140

i got these from www.aa-mfg.com, they are pretty cheap like 10 bux each.

bought em at 1.25 dia and had em bored to 1-3/8. that...

Here is our update.

Thanks to mike laws for the electronics and the enclosure!

Has anyone make a automatic torch igniter that works perfect everytime?

I learned so much about building cars, 4x4 trucks and stuff from mags. Thats where I got all my ideas and then I started to do some of it myself and became pretty good at it. I didnt become a car guy...
